Description:FIELD OF THE INVENTION

[0001] The present invention relates to a vehicle mudguard cleaning and protective system for cleaning and protecting surfaces of vehicles, particularly those exposed to mud, moisture, and environmental contaminants, thereby improving vehicle’s maintenance efficiency, durability, and long-term protection against external conditions.

BACKGROUND OF THE INVENTION

[0002] Vehicles frequently operate in varied environmental conditions, exposing certain areas to excessive accumulation of unwanted substances. Surfaces that are in close proximity to roads, off-road terrain, and wet or dusty environments tend to retain layers of dirt and moisture, which over time lead to reduced performance, inefficiencies, and increased maintenance needs. Continuous exposure to moisture, road grime, and temperature variations accelerates surface wear and degradation, requiring frequent cleaning and upkeep. Existing cleaning methods are often manual, inefficient, and inconsistent, failing to address persistent accumulation and surface damage effectively.

[0003] Conventional maintenance methods rely on manual intervention, which is often time-consuming, labor-intensive, and inefficient in addressing stubborn deposits. While some external cleaning solutions provide temporary relief, they fail to prevent repeated accumulation or mitigate damage over time. Moreover, inconsistent cleaning procedures may result in incomplete removal of contaminants, thus causing persistent issues that impact vehicle longevity and operational efficiency.

[0004] The challenges associated with removing adhered material are further compounded by environmental factors, including variable weather conditions, high humidity, and uneven terrain exposure. These conditions exacerbate the retention of unwanted substances, leading to increased frequency of maintenance cycles and higher long-term upkeep costs. Additionally, inadequate preventive measures contribute to early-stage degradation, requiring costly repairs or replacements over time.

[0005] KR0126306B1 discloses about an invention having a slit-shaped fender access hole in the wheel house of the vehicle to provide a fender cleaning device for cleaning the dirt fleece while passing through a contaminated road, such as a muddy road. And the blades and which protrude into the mudguard entrance holes and are preloaded on both sides of the mudguard through the pressure plates and of the wheel house. While installed on both sides, the inner side of the wheel house is configured by winding the upper end of the mudguard to the winding roller attached to the winding motor.

[0006] CN221114109U discloses about an invention having a utility model belongs to the technical field of automobile wheel covers, in particular to a self-cleaning automobile wheel cover, which comprises an automobile wheel cover main body, wherein a mud guard self-cleaning component is arranged in the automobile wheel cover main body, a tire cleaning component is arranged on one side of the automobile wheel cover main body, and a mud guard component is arranged at the bottom of the automobile wheel cover main body; the self-cleaning assembly of the mudguard comprises a hollowed-out layer, a filtering hole and a water outlet, wherein the filtering hole is formed in the hollowed-out layer, and the bottom of the filtering hole is communicated with the water outlet; the filter holes and the water outlets form a communication structure through the hollowed-out layer, the filter holes are arranged at equal intervals relative to the inside of the hollowed-out layer, and the water outlets are arranged at equal intervals relative to the bottom of the hollowed-out layer; the utility model is convenient for flushing the mud guard, ensures the cleanliness, does not need manual water injection, is convenient for protecting the mud guard, and prolongs the service life of the mud guard.

[0007] Conventionally, many methods are available for cleaning the mudguards of vehicle. However, the cited invention lacks in providing a fully automated, cleaning method that integrates multiple cleaning and protective features into a single system. Existing solutions rely on mechanical components, such as blades, pressure plates, and winding rollers, or passive water flushing mechanisms with filtering holes and water outlets, which, while effective to an extent, do not offer a comprehensive approach to mud removal, protection, and maintenance. These methods often require continuous physical contact, leading to increased wear and tear, or depend on external factors like water flow, making them less efficient in ensuring thorough cleaning under all conditions. Additionally, the absence of real-time detection and automated actuation based on actual mud accumulation makes such systems reactive rather than proactive, thus leading to inefficient cleaning cycles and frequent maintenance needs.

[0008] To overcome the aforementioned drawbacks, there exists a need in the art to develop a more automated, efficient, and reliable system capable of detecting, cleaning, and protecting vehicle surfaces from external contaminants. An optimized solution must integrate automated monitoring, cleaning methods, and protective applications for ensuring minimal user intervention while maximizing effectiveness and longevity. A system that proactively address surface accumulation, remove unwanted deposits, and enhance durability would significantly improve maintenance efficiency and overall vehicle performance.

OBJECTS OF THE INVENTION

[0009] The principal object of the present invention is to overcome the disadvantages of the prior art.

[0016] Another object of the present invention is to develop a system that preserve the visual appeal of the vehicle by preventing the accumulation of unwanted substance for ensuring that exposed surfaces remain clean and well-maintained, thereby sustaining the aesthetic appearance over extended periods.

[0017] Yet another object of the present invention is to develop a system that ensures the cleaning process is carried out under safe conditions to prevent activation while the vehicle is in motion.

[0018] The foregoing and other objects, features, and advantages of the present invention will become readily apparent upon further review of the following detailed description of the preferred embodiment as illustrated in the accompanying drawings.

SUMMARY OF THE INVENTION

[0019] This summary is provided to introduce a selection of concepts in a simplified format that are thoroughly described in the detailed description of the invention. This summary is not intended to identify key or essential inventive concepts of the invention, nor is it intended for determining the scope of the invention.

[0020] The present invention relates to a vehicle mudguard cleaning and protective system, for removing accumulated mud, moisture retention, and corrosion that impact vehicle components. The disclosed system aims to automatically detect and remove mud, apply protective coatings, and provide maintenance alerts, thereby enhancing vehicle longevity and reducing manual cleaning efforts.

[0021] In accordance with an embodiment of the present invention, a vehicle mudguard cleaning and protective system, comprises of a sensing unit integrated with a detection means to identify the presence of accumulated mud, moisture, and potential rust formation on the surface of the mudguard. The sensing unit includes a capacitive sensor for detecting moisture levels and an optical sensor for detecting clumps of mud or corrosion. Upon detection, a microcontroller processes the data and communicates with the vehicle's control unit to notify the user via the dashboard.

[0022] To facilitate automated cleaning, a plurality of vibration units is installed along the mudguard, which are actuated upon receiving signals from the microcontroller. These vibration units, configured as piezoelectric actuators, generate vibrations to dislodge adhered mud. A scrubber is provided, comprises of a sliding member mounted on the bottom surface of the mudguard and equipped with brushes arranged in an arced manner to scrub across the entire width of the mudguard. The system further incorporates a fluid-based cleaning means, wherein a series of openings along the scrubber are connected to a container containing a mud dispersant fluid. The fluid is sprayed through nozzles onto the mudguard, aiding in the removal of stubborn mud deposits. A tapping arrangement is also integrated into the system, utilizing a reciprocating piston to apply mechanical force onto the mudguard, further assisting in dislodging firmly adhered debris.

[0023] For extended protection, the system includes a set of sprayers positioned along the mudguard, which are connected to a multi-sectioned chambercontaining a hydrophobic coating. This coating is applied onto the surface of the mudguard to repel water and prevent the accumulation of moisture for reducing the risk of rust formation. The sprayers are rotatably mounted via hinges to ensure complete coverage of the mudguard surface.

[0024] In addition to cleaning functions, the system features a corrosion prevention mechanism, wherein an optical sensor detects signs of rust on the mudguard. Upon detection, the system triggers the application of an anti-rust coating via dedicated nozzles, which are connected to a multi-section chamber containing the protective solution. This process enhances the durability of the mudguard and minimizes maintenance requirements.

[0025] The system is designed with operational safety measures, ensuring that the cleaning process is only initiated when the vehicle is stationary. The microcontroller receives driving and halt condition data from the vehicle's control unit and prevents manual actuation of the cleaning means while the vehicle is in motion. A dashboard alert is generated for instructing the user to bring the vehicle to a halt before proceeding with cleaning operations.

[0026] In accordance with yet another embodiment of the present invention, a method for cleaning and protecting the mudguard, has been provided, which includes the steps of detecting presence of moisture levels and clumps of mud adhered with the bottom surface of the mudguard. The collected data is processed by a microcontroller, which communicates with the vehicle's control unit to generate an alert on the dashboard, informing the user of the need for cleaning. Once the presence of mud is confirmed, the method proceeds with vibrating the mudguard using multiple piezoelectric actuators arranged along its surface. These actuators generate mechanical vibrations, aiding in the dislodging of adhered mud. Simultaneously, a scrubber is activated, wherein a sliding member integrated with an array of brushes moves across the width of the mudguard, scrubbing off accumulated debris.

[0027] To further enhance cleaning efficiency, a mud dispersant fluid is sprayed onto the mudguard through multiple openings over the member. The dispersant fluid assists in loosening stubborn dirt particles, making removal more effective. A tapping arrangement, consisting of a reciprocating piston, applies mechanical force to the mudguard to aid in dislodging firmly adhered mud. After cleaning, the method includes applying a hydrophobic coating to the mudguard to prevent moisture retention and reduce future accumulation of dirt. The coating is sprayed onto the surface via a set of rotatable sprayers, ensuring complete coverage. To prevent rust formation, an additional step is performed where an anti-rust coating is dispersed onto the mudguard through dedicated nozzles, further extending the longevity of the vehicle's components.

[0028] The method also incorporates an essential safety means to ensure that cleaning operations do not interfere with vehicle operation. Before initiating any cleaning procedures, the microcontroller receives driving and a halt condition data from the vehicle’s ECU. If the vehicle is in motion, the system prevents manual activation of the cleaning process and generates an alert on the dashboard, instructing the user to bring the vehicle to a stationary condition before proceeding.

[0029] While the invention has been described and shown with particular reference to the preferred embodiment, it will be apparent that variations might be possible that would fall within the scope of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

[0031] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting.

[0032] In any embodiment described herein, the open-ended terms "comprising," "comprises,” and the like (which are synonymous with "including," "having” and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[0033] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0034] The present invention relates to a vehicle mudguard cleaning and protective system specifically designed to remove accumulated contaminants and provide protective treatment. The system enables automated detection, cleaning, and protection for ensuring efficient removal of adhered substances while minimizing manual intervention and maintenance efforts.

[0035] Figure 1 exemplarily illustrates a perspective view of a mudguard 101 configured with a vehicle mudguard cleaning and protective system. Figure 2 exemplarily illustrates a bottom view of the mudguard 101 associated with the system. The system is primarily installed on a mudguard 101 of a vehicle having a member 202 mounted with the bottom surface 201 of the mudguard 101, plurality of vibration units 203 arranged along the mudguard 101, the member 202 is mounted by means of a pair of sliding units 204 arranged parallel along the bottom surface 201 of the mudguard 101 that include a track 204a fabricated over the bottom surface 201 of the mudguard 101 and a pair of motorized rollers 204b resting over the track 204a and coupled with the member 202, a scrubber 205 mounted on the member 202, a container 206 arranged with the member 202, a plurality of sprayers 207 is mounted at a bottom surface 201 of mudguard 101 attached with a multi-section chamber 102 via conduits 103, each attached with hinges 208 and a plurality of nozzles 209 is provided on the mudguard 101 attached with the multi-sectioned chamber 102 via conduits 103.

[0036] The system disclosed herein includes a sensing unit 301 designed for detecting accumulated mud, moisture, and debris on the bottom surface 201 of a vehicle’s mudguard 101. The sensing unit 301 comprises a capacitive sensor for detecting moisture and an optical sensor for identifying clumps of mud. These sensors are mounted on a curved member 202 integrated with the bottom surface 201 of the mudguard 101. The sensors continuously monitor environmental conditions and detect the presence of mud accumulation, water retention, or debris adhered to the mudguard 101. The collected data is then transmitted to a microcontroller, which processes the information and determines whether cleaning is required. The output pin of the sensor is connected to an analog/digital input pin of the microcontroller for feeding the real time information.

[0037] The capacitive sensor is configured to detect the presence of moisture by measuring changes in capacitance levels due to water or wet mud accumulation. Capacitive sensors function by detecting variations in dielectric properties, which occur when moisture accumulates on the surface of the mudguard 101. When water or damp mud adheres to the mudguard 101, the sensor registers an increase in capacitance, thus triggering a signal that is sent to the microcontroller. This detection helps prevent prolonged moisture retention, which otherwise lead to rust formation and corrosion of the mudguard 101.

[0038] On the other hand, the optical sensor is responsible for detecting solid clumps of mud and debris adhered to the mudguard 101. The optical sensor operates by emitting light, typically in the infrared spectrum, and measuring the reflection or absorption characteristics of the surface. Clean surfaces or those with minimal dirt reflect light differently compared to surfaces covered with mud. By analyzing these reflections, the optical sensor determines the extent of mud accumulation for distinguishing between minor dirt deposits and significant obstructions that require cleaning.

[0039] The sensing unit 301 is integrated with a processor for processing real-time data to allow the microcontroller to assess the severity of mud accumulation. The microcontroller is pre-fed with a threshold level, beyond which an automated pop-up alert is generated. If any of the categories i.e. first category in which the detected moisture level exceeds a predefined limit or second category in which the optical sensor identifies substantial mud buildup, or the third category if both the values of optical sensor and capacitive sensor, in combination exceed a threshold value, the system activates an alert. The microcontroller carries out corresponding operations based on the detected category.

[0040] The alert is communicated via a dashboard of the vehicle for notifying the user about the need for cleaning when the second or the third categories are detected. The dashboard notification serves as an early warning for ensuring that the mudguard 101 is cleaned before excessive accumulation affects vehicle performance or safety. The dashboard includes an option of manual activation of the cleaning operation. In case no command is received from the user for a threshold period of time, the microcontroller embedded within the system communicates the information regarding the second or the third category with the control unit of the vehicle that is an ECU (Engine Control Unit). In an embodiment, the threshold period of time may extend from 1 to 5 days and is changed by a user. The ECU continuously monitors vehicle movement, including parameters such as speed, wheel rotation, and acceleration.

[0041] When the cleaning process is manually or automatically triggered, the microcontroller first checks the vehicle's operational status by retrieving the instant condition of the vehicle, selected from a driving condition and a halt condition, to prevent a manual actuation of cleaning of the mudguard 101 upon detection of the driving condition and an alert is pushed to the vehicle’s dashboard display, regarding bringing the vehicle to the halt condition prior to initiating cleaning operations. If the vehicle is detected to be in a driving condition, the microcontroller immediately blocks the execution of the cleaning process for ensuring that cleaning operations are only carried out when the vehicle is safely halted.

[0042] The alert is communicated via a dashboard of the vehicle for notifying the user about the need for cleaning when the second or the third categories are detected. The dashboard notification serves as an early warning for ensuring that the mudguard 101 is cleaned before excessive accumulation affects vehicle performance or safety. The dashboard includes an option of manual activation of the cleaning operation.

[0043] In case, no command is received from the user for a threshold period of time, the microcontroller embedded within the system communicates the information regarding the second or the third category with the control unit of the vehicle that is an ECU (Engine Control unit) which in turn receives driving or halt condition data from the ECU. In an embodiment, the threshold period of time may extend from 1 to 5 days and can be changed by a user The ECU continuously monitors vehicle movement, including parameters such as speed, wheel rotation, and acceleration. When the cleaning process is manually or automatically triggered, the microcontroller first checks the vehicle's operational status by retrieving the driving condition data. If the vehicle is detected to be in motion, the microcontroller immediately blocks the execution of the cleaning process and pushes an alert to the vehicle’s dashboard display.

[0044] The dashboard alert notifies the driver or user that the cleaning process cannot proceed while the vehicle is in motion and instructs them to bring the vehicle to a complete stop before retrying the cleaning operation. This real-time feedback prevents activation of the cleaning mechanism during transit, thereby avoiding distractions or potential risks associated with vehicle operation.

[0045] In an embodiment of the present invention, the microcontroller is pre-fed with a predefined speed threshold that determines when cleaning operations are executed. If the vehicle is moving above 0 km/h, the system remains in a locked state for preventing any manual or automatic activation. Once the vehicle speed is 0 km/h i.e. stationary condition for a predefined duration (10-30 minutes), the microcontroller then unlocks the system, for allowing the cleaning operation to proceed.

[0046] In another embodiment of the present invention, the system is configured with voice and haptic feedback. If a user attempts to activate the cleaning function while the vehicle is in motion, an audio alert is played through the vehicle’s infotainment system or speaker for providing warning the driver of the restriction. Simultaneously, the haptic feedback (such as vibrations in the steering wheel or seat) is used to reinforce the alert for ensuring that the driver immediately acknowledges the restriction.

[0047] In yet another embodiment of the present invention, the driving condition detection is integrated with remote access. For example, if the user attempts to activate the cleaning process via a mobile application while the vehicle is parked but still in a driving state (such as on a slight incline), the system rejects the request and notifies the user via a mobile push notification. This implementation extends the safety mechanism beyond in-vehicle controls for ensuring remote monitoring of cleaning operations.

[0048] When the vehicle is stationary and the system initiates the cleaning process, the microcontroller operatively commands a plurality of vibration units 203 arranged along the bottom surface 201 of the mudguard 101 of a vehicle to dislodge adhered mud and debris through controlled vibratory motion. Each vibration units 203 is configured as a piezoelectric actuator, which is capable of generating precise, high-frequency vibrations upon electrical excitation. Piezoelectric actuators operate on the principle of piezoelectricity, where certain materials generate mechanical strain when subjected to an electrical voltage. When activated, the piezoelectric actuators produce rapid oscillations for causing the mudguard 101 to vibrate at a controlled frequency in view of effectively loosening and detaching dried and adhered mud particles from its surface. The piezoelectric actuators are mechanically fabricated with the peripheral surface of the mudguard 101 by means of one or more fasteners and brackets (not shown in the figure). In another embodiment of the present invention, the piezoelectric actuators may be installed within the thickness of the mudguard 101 at the time of manufacturing.

[0049] The vibration units 203 are actuated based on signals received from the microcontroller, which continuously monitors the mud accumulation status through the sensing unit 301. If the capacitive and optical sensors detect a significant level of moisture and mud (i.e. third category), the microcontroller triggers the vibration units 203 to initiate a cleaning cycle. The vibratory motion facilitates the initial removal of loose mud for reducing the adhesion strength of remaining debris.

[0050] In an embodiment of the present invention, the vibration units 203 are pre-fed to operate at variable frequencies based on the severity of mud accumulation. For light debris, the system initiates low-frequency vibrations, sufficient to shake off loose particles. However, for heavier mud deposits, the actuators generate higher-frequency oscillations for ensuring effective dislodging of firmly adhered dirt without damaging the mudguard 101. The adaptive vibration control enhances the efficiency and longevity of the cleaning process.

[0051] In another embodiment of the present invention, the vibration units 203 are activated in a sequential pattern, instead of operating all at once. The microcontroller coordinates a wave-like activation sequence, where adjacent actuators vibrate in a phased manner for creating a progressive movement of dislodged mud away from the mudguard’s 101 surface. This wave propagation manner prevents re-deposition of mud and ensures a more uniform cleaning effect across the entire width of the mudguard 101.

[0052] Furthermore, the vibration units 203 are integrated with real-time feedback monitoring. The system detects changes in vibration intensity and mud adhesion resistance for allowing the microcontroller to adjust the vibration frequency dynamically. If a particular region of the mudguard 101 retains excessive mud despite initial vibrations, the system automatically increases the vibration intensity for that specific area for optimizing cleaning performance.

[0053] An advantage of using the piezoelectric actuators used in the vibration units 203 are selected for their low power consumption, high durability, and rapid response time due to direct connection. Unlike traditional mechanical vibration mechanisms, piezoelectric actuators require minimal energy input, making them highly efficient for vehicle applications. Additionally, they offer precise control over vibration frequency and amplitude for ensuring that the cleaning process is gentle yet effective, without causing excessive wear on the mudguard 101 material.

[0054] In yet another embodiment of the present invention, the positioning of vibration units 203 is optimized for different vehicle types. For heavy-duty trucks and off-road vehicles, where mud accumulation is more severe, the actuators are placed in higher-density arrangements for ensuring more intense vibration coverage. In smaller passenger vehicles, a lower density of actuators is used for providing sufficient cleaning while minimizing power consumption.

[0055] Figure 3 exemplarily illustrates an isometric view of a member 202 installed over the mudguard 101 having a sensing unit 301 mounted on the member 202, a plurality of openings 302 is formed along the member 202, a tapping arrangement 303 provided on the member 202 by means of fasteners 304, the tapping arrangement 303 comprises a bracket 303a attached on the member 202, a spring loaded piston 303b slidably coupled with the bracket 303a being reciprocated by a rotating cam 303c mounted in the bracket 303a.

[0056] After dislodging the initial level of adhered mud from the mudguard 101, the next step is to perform a second level of cleaning of the mudguard 101, for which a scrubber 205 is mounted on the member 202 which is equipped with a plurality of brushes 204a. The member 202 is installed on the bottom surface 201 of the mudguard 101 and is integrated in a slidable manner by means of a pair of sliding units 204 arranged parallel to each other. The sliding units 204 provide controlled linear movement along the length of the mudguard 101 for enabling the scrubber 205 to traverse and cover the entire length and width of the mudguard 101 for a thorough cleaning effect.

[0057] The sliding units 204 enable the controlled linear translation of the scrubber 205 along the bottom surface 201 of the mudguard 101 for ensuring efficient and uniform cleaning. The sliding units 204 are parallelly arranged and serve as a guiding means for allowing the member 202 to move smoothly back and forth across the entire width of the mudguard 101. The movement is controlled by the microcontroller, which regulates the speed and direction of translation based on the level of mud accumulation detected by the sensing unit 301.

[0058] The sliding units 204 operates through a motorized means where each of the sliding units 204 includes a track 204a fabricated over the bottom surface 201 of the mudguard 101 and a pair of motorized rollers 204b resting over the track 204a and coupled with the member 202. The motorized rollers 204b serve as drive components that are powered by electric motors that receive control signals from the microcontroller. Upon activation, the motors rotate the rollers 204b, generating a controlled linear motion along the track 204a, thereby facilitating the smooth translation of the member 202 over the bottom surface 201 of the mudguard 101.

[0059] The microcontroller adjusts the motor speed to optimize cleaning efficiency and increasing the translation speed for light mud deposits and reducing it when stubborn debris is detected, allowing for intensive scrubbing action. The rollers 204b maintain consistent traction with the track 204a for ensuring stable movement without slippage. Also, the direction of translation is reversed after each cleaning pass for ensuring that the entire width of the mudguard 101 is thoroughly scrubbed.

[0060] As the member 202 translates along the sliding units 204, the scrubber 205 equipped with arced brushes 204a, makes continuous contact with the mudguard 101 surface for dislodging adhered mud and debris. The sliding units 204 ensure stability for preventing misalignment or uneven cleaning, while linear guides minimize friction for allowing smooth, low-resistance movement.

[0061] In another embodiment of the present invention, the scrubber 205 employs rotating cylindrical brushes, which spin as they move along the sliding track 204a. These rotating brushes provide enhanced mechanical cleaning, particularly useful for removing firmly adhered mud and debris that is not dislodged by vibration alone. The rotational speed of the brushes is adjustable for allowing the system to adapt to different levels of mud accumulation.

[0062] A plurality of openings 302 is formed on the member 202 through which a mud dispersant fluid is sprayed onto the bottom surface 201 of the mudguard 101. These openings 302 are crafted at different positions to ensure uniform distribution of the fluid, softening hardened mud and reducing adhesion strength for making it easier to scrub off debris. The openings 302 are connected to a fluid container 206, which is arranged within the member 202 and supplies the dispersant fluid.

[0063] The fluid is controlled by the microcontroller, which regulates the flow rate and activation timing based on data from the sensing unit 301. Upon detecting excessive mud accumulation, the microcontroller activates the dispersal of the fluid for allowing the pressurized fluid to be sprayed through the openings 302 in the member 202. This pre-treatment stage ensures that hardened mud layers are sufficiently loosened before the scrubbing and vibration mechanisms are engaged.

[0064] In an embodiment of the present invention, the fluid dispersal includes adjustable spray valves for capable of directing fluid at different angles to ensure maximum coverage. The sprayers 207 are configured to oscillate or rotate for enabling precision spraying even in difficult-to-reach areas of the mudguard 101. The pressure and volume of fluid release is also dynamically adjusted, depending on the severity of mud accumulation for ensuring optimal fluid usage and minimal wastage.

[0065] In yet another embodiment, the mud dispersant fluid includes but not limited to be a bio-degradable cleaning agent for reducing the environmental impact of vehicle maintenance. The system may also be configured to heat the dispersant fluid in colder climates for ensuring that frozen mud deposits are efficiently melted and removed.

[0066] In addition to fluid dispersal and scrubbing, the system incorporates a tapping arrangement 303 for removing firmly adhered mud that is not effectively dislodged by vibration or fluid alone (Fig. 3). This tapping arrangement 303 applies mechanical impact force to the mudguard 101 for causing hardened debris to break apart and detach.

[0067] The tapping arrangement 303 is mounted on the member 202 by means of fasteners 304 such as threaded fasteners, rivets, adhesives. The tapping arrangement 303 comprises of a bracket 303a attached to the slidable member 202 supporting the scrubber 205. The bracket 303a houses a spring-loaded piston 303b, which is slidably coupled within the bracket 303a. This piston 303b is actuated by a rotating cam 303c, also mounted within the bracket 303a for enabling reciprocating motion of the piston 303b.

[0068] The tapping action is generated as the rotating cam 303c pushes the spring-loaded piston 303b forward, causing it to strike the mudguard 101 with controlled force. Once the cam 303c rotates further, the piston 303b retracts under spring tension for preparing for the next tapping cycle. The cam 303c is coupled with a motor at an eccentric point which enables the linear motion of the spring loaded piston 303b. This continuous impact ensures that stubborn, dried, or hardened mud layers are mechanically loosened, making them easier to remove during the subsequent scrubbing process. The tapping arrangement 303 operates in synchronization with the fluid dispersal and scrubber 205 as the mud dispersant fluid is sprayed onto the mudguard 101 to soften the mud layer. The tapping arrangement 303 is activated, generating controlled impacts to break apart and dislodge hardened debris. The slidable scrubber 205 translates across the mudguard 101, using brushes 204a to remove the loosened debris.

[0069] In an embodiment of the present invention, the tapping arrangement 303 utilizes an electromagnetic solenoid actuator that consists of a coil wound around a ferromagnetic core, which, when energized, generates a strong magnetic field, causing a plunger or striking rod to move forward and tap against the mudguard 101 surface. The microcontroller controls the frequency and intensity of the tapping action by modulating the electrical current supplied to the solenoid coil. When activated, the solenoid generates a series of rapid, controlled impacts against the mudguard 101, breaking apart firmly adhered mud layers. After deactivation, the plunger returns to its resting position via a spring return mechanism and ready for the next cycle.

[0070] In an alternative implementation, multiple solenoids are positioned along the length of the mudguard 101 for allowing for independent activation of different sections. This sectional tapping control ensures targeted mud removal for optimizing energy consumption and improving cleaning effectiveness.

[0071] In another embodiment of the present invention, the tapping arrangement 303 operates via a pneumatic piston actuator, which generates controlled impacts through compressed air pressure. The system includes:

• A pneumatic cylinder mounted on a bracket 303a attached to the slidable member 202.
• A compressed air reservoir housed within the vehicle chassis or sourced from the existing vehicle air system (if applicable).
• A solenoid-controlled air valve that regulates air pressure and piston stroke frequency.

[0072] During operation, the microcontroller actuates the pneumatic valve, directing pressurized air into the cylinder, which extends the piston to strike the mudguard 101. Once the air pressure is released, the piston retracts, completing one tapping cycle. The pneumatic tapping offers adjustable impact force, allowing the system to increase or decrease air pressure based on mud adhesion levels. This makes it particularly effective for off-road vehicles and heavy-duty trucks, where thicker mud layers require stronger mechanical impact to be effectively dislodged.

[0073] In yet another embodiment of the present invention, the tapping arrangement 303 utilizes a motorized eccentric cam system, where a rotating camshaft with an offset lobe cyclically pushes and releases a striker against the mudguard 101 surface. This arrangement 303 consists of a small DC motor or stepper motor driving the camshaft, a striker rod that is periodically lifted and dropped as the cam rotates, and a spring return system that ensures the striker moves back into position after each impact. The rotation speed of the camshaft determines the tapping frequency, while the lobe size and shape define the impact force applied to the mudguard 101, enabling continuous and repetitive tapping action for efficient removal of stubborn mud deposits. In the exemplary embodiment of the present invention, i.e. figure 3, no element is attached at the end point of the system, however as per the variations, different shape elements can be attached to interact with the bottom surface 201 of the mudguard 101.

[0074] In an embodiment, for enhanced performance, the tapping arrangement 303 is integrated with an accelerometer-based feedback, which detects the impact effectiveness of each tap. If residual mud is still detected after a tapping cycle, the system automatically increases the frequency or duration of tapping for ensuring maximum cleaning efficiency.

[0075] Multiple sprayers 207 are mounted via hinges 208 onto the mudguard 101 for allowing them to rotate and adjust their spray angles for complete coverage of the entire bottom surface 201. The hinged design enables the sprayers 207 to be positioned in an aligned manner for ensuring that every section of the mudguard 101 is effectively coated. The sprayers 207 are adjusted to different angles for allowing the coating to be applied uniformly, including on curved or hard-to-reach areas of the mudguard 101.

[0076] Each of the hinges 208 is imparted a rotational motion via a motor regulated by a motor driver in communication with the microcontroller. This configuration enables automated spray angle adjustments for ensuring that fluid dispersal is optimized based on the vehicle's conditions and mudguard 101 shape. The microcontroller determines the ideal positioning of the sprayers 207 based on feedback for adjusting the rotation speed and angle for maximum efficiency.

[0077] A hydrophobic coating is stored in a multi-sectioned chamber 102, which is connected to the sprayers 207 via conduits 103 disposed over the mudguard 101. The microcontroller regulates the flow rate and spray timing for ensuring that an optimal amount of coating is applied to the mudguard 101. The spraying process is triggered automatically based on predefined conditions, such as post-cleaning operations, changes in humidity, or detection of excessive moisture by the sensing unit 301. This ensures that the mudguard 101 remains protected under varying environmental conditions.

[0078] The system is equipped with a weather module linked to the control unit for enabling real-time weather analysis and forecasting. The weather module receives weather data, including rainfall predictions, and communicates with the microcontroller to determine whether preemptive hydrophobic coating application is necessary. Upon receiving a positive forecast for rain, the microcontroller automatically triggers the sprayers 207 to apply the hydrophobic coating onto the mudguard 101 for ensuring that the surface is adequately protected before exposure to wet conditions. This proactive approach minimizes water retention, reduces the formation of mud deposits, and prevents potential rust development.

[0079] If light rain is predicted, the sprayers 207 applies a standard coating layer, whereas in cases of heavy rainfall or extended wet conditions, the microcontroller increases the coating thickness to enhance water repellency. The sprayers 207, mounted via motorized hinges 208, adjust their angles to provide full coverage, ensuring that all critical areas of the mudguard 101 are evenly coated.

[0080] In an embodiment of the present invention, the system incorporates a pressure-regulated spraying process, where the flow of the hydrophobic coating is adjusted based on the level of dirt accumulation and environmental exposure. If high levels of moisture or mud adhesion are detected, the microcontroller increases the flow rate to ensure a thicker layer of coating is applied for providing greater protection against water and dirt adhesion. The spray patterns may be conical, fan-shaped, or jet-based, depending on the area requiring coating coverage. The system also includes automated self-cleaning sprayers 207 that prevent clogging and buildup of residual coating material over time.

[0081] In another embodiment of the present invention, the sprayers 207 are motorized and capable of rotating at a controlled speed. This allows the hydrophobic coating to be applied dynamically for ensuring consistent coverage even if the vehicle’s mudguard 101 has an irregular shape or curvature. The rotation speed of the sprayers 207 is controlled by the microcontroller, which adjusts the movement based on the area that requires coating.

[0082] In yet another embodiment of the present invention, the hydrophobic coating incorporates self-healing nanotechnology, where the applied layer automatically repairs micro-abrasions and minor scratches. This extends the lifespan of the coating and ensures continuous protection, even in high-wear conditions such as off-road or heavy-duty vehicle applications.

[0083] Herein, the sensing unit 301 with optical sensor detect rust formation on the mudguard 101 surface. The optical sensor operates by emitting light (infrared or visible spectrum) onto the surface and analyzing the reflected signal. Since rust has distinct optical properties compared to clean metal or painted surfaces, the sensor distinguishes rusted areas from non-corroded sections by detecting color variations and surface texture changes. The sensor continuously scans the surface and sends real-time data to the microcontroller, which processes the information and determines whether rust has begun forming. If rust is detected, the microcontroller generates a notification, which is communicated to the vehicle’s dashboard display for alerting the user to undertake maintenance activities for corrosion prevention.

[0084] A series of sprayers 207 is mounted along the mudguard 101 which is responsible for dispensing the anti-rust coating onto the affected areas. These sprayers 207 are connected via a network of conduits 103 to a dedicated anti-rust coating multi-section chamber 102, securely housed over the mudguard 101. Upon receiving the rust detection signal, the microcontroller activates the nozzles 209 for allowing the pressurized anti-rust solution to be sprayed directly onto the rusted sections of the mudguard 101. The coating forms a protective barrier for preventing further oxidation and deterioration of the metal surface.

[0085] In an embodiment of the present invention, the rust detection is enhanced with electrochemical sensors, which measure the oxidation levels and metal conductivity of the mudguard 101. This allows for early-stage rust detection, even before visible discoloration appears. The system continuously monitors corrosion progression, and if oxidation levels exceed a predefined threshold, an automatic anti-rust coating cycle is initiated.

[0086] In another embodiment of the present invention, the anti-rust sprayers 207 apply a two-stage protective coating: The first layer consists of a corrosion inhibitor, which neutralizes oxidation and prevents further rusting. The second layer is a durable polymer-based sealant, which shields the metal surface from moisture and road debris.

[0087] In another embodiment of the present invention, the anti-rust coating process is equipped with a pre-set scheduling feature for allowing users to set periodic maintenance cycles for automatic rust prevention. Additionally, the system is remotely activated via a mobile application for enabling on-demand anti-rust coating application even when the vehicle is parked or stored for extended periods.

[0088] In yet another embodiment of the present invention, the sensing unit 301 is configured for continuous scanning to detect the presence of rust formation on the mudguard 101. Upon completion of the cleaning cycle, the sensing unit 301 re-evaluates the surface condition, and if rust is detected, the microcontroller autonomously triggers the activation of the nozzles 209. The nozzles 209, connected to the multi-section chamber 102 containing an anti-rust solution, are controlled via electromechanical valves for ensuring precise solution dispersal over the affected areas. The anti-rust coating is uniformly applied for forming a protective barrier that prevents further oxidation and corrosion. The microcontroller regulates the flow rate and coverage area based on the extent of rust detected in view of ensuring optimal coating efficiency.

[0089] The present invention further provides a systematic method for cleaning and protecting a vehicle's mudguard 101 for ensuring efficient removal of adhered mud, prevention of corrosion, and enhanced durability. The method ensures that mud and debris do not accumulate, which lead to performance deterioration, excessive wear, and corrosion.

[0090] To ensure safe and controlled activation, the method incorporates real-time vehicle status monitoring and allows cleaning to be performed only when the vehicle is stationary, thus preventing unintended operation while in motion. The method follows a structured sequence of operations, controlled by the microcontroller and vehicle control unit (ECU) to ensure safe and optimized execution.

Step 1: Receiving Input for Cleaning Operations

• The system receives an input command to initiate cleaning operations.
• The input is triggered manually by the user through the dashboard interface or automatically by the sensing unit 301, based on mud accumulation levels detected via optical and capacitive sensors.
• If mud levels exceed a predefined threshold, an automatic alert is generated for notifying the user that cleaning is required

Step 2: Determining Instant Condition of the Vehicle

• The microcontroller communicates with the Electronic Control Unit (ECU) to determine the instant condition of the vehicle.
• The system evaluates whether the vehicle is in a driving condition or a halt condition, using data from the ECU, which monitors:
o Speed of the vehicle
o Wheel rotation
o Acceleration

Step 3: Alerting the User if the Vehicle is in a Driving Condition

• If the vehicle is detected to be in a driving condition, the microcontroller blocks the execution of cleaning operations.
• A dashboard alert is displayed, notifying the user that cleaning cannot be initiated while the vehicle is in motion.
• The system instructs the user to bring the vehicle to a halt condition before proceeding with cleaning and protective measures.

Step 4: Initiating Cleaning and Protection Upon Halt Condition

Once the vehicle is confirmed to be stationary, the cleaning and protection sequence is initiated. The process of cleaning and protection is as follows:

Step A: Detecting Mud Adhered to the Mudguard 101

[0091] The process begins with the detection of mud accumulation on the bottom surface 201 of the mudguard 101. The sensing unit 301, comprising a capacitive sensor for moisture detection and an optical sensor for identifying mud deposits, continuously monitors the surface condition of the mudguard 101. The collected data is processed by the microcontroller, which evaluates whether the mud accumulation exceeds a predefined threshold. If cleaning is required, the system notifies the user via a dashboard alert for allowing for manual activation if necessary.

Step B: Vibrating the Mudguard 101 to Dislodge Mud

[0092] After detecting the presence of mud, the system activates a plurality of vibration units 203 that are configured as piezoelectric actuators, which generate high-frequency vibrations when an electrical current is applied. The vibrations cause the mudguard 101 to oscillate, loosening the adhered mud particles and making them easier to remove in subsequent cleaning stages.

Step C: Spraying Mud Dispersant Fluid onto the Mudguard 101

[0093] Once the vibrations dislodge loosely adhered mud, the system sprays a mud dispersant fluid onto the mudguard 101 surface to break down stubborn deposits. The dispersant fluid is stored in a container 206 over the mudguard 101 and is supplied to the openings 302. The sprayers 207 are positioned along the mudguard 101 to spray the fluid in a uniform pattern for ensuring complete surface coverage.

Step D: Scrubbing the Mudguard 101 Surface

[0094] After the mud dispersant fluid softens adhered mud, the scrubber 205 consists of a plurality of brushes 204a arranged in an arced manner for ensuring maximum surface contact during cleaning while translating via the sliding units 204. As the scrubber 205 moves, its bristles effectively scrape off softened mud for preventing accumulation in critical areas of the mudguard 101.

Step E: Tapping the Mudguard 101 for Removing Firmly Adhered Mud

[0095] In cases where mud remains stubbornly adhered, the system incorporates a tapping arrangement 303 to provide mechanical impact force, further loosening hardened debris. The tapping mechanism consists of a spring-loaded piston 303b, which is reciprocated by a rotating cam 303c mounted on a bracket 303a attached to the member 202. As the camshaft rotates, it pushes and releases the spring-loaded piston 303b, generating cyclic impact forces on the mudguard 101. These controlled taps break apart hardened mud layers, which are then scrubbed away by the brushes 204a.

Step F: Spraying Hydrophobic Coating onto the Mudguard 101

[0096] Once the mudguard 101 surface is fully cleaned, the system applies a hydrophobic coating to prevent future accumulation of mud and moisture. Also, the hydrophobic coating is applied upon receiving a positive forecast of rain by means of a weather module for applying a protective barrier over the mudguard 101 to eliminate chances of mud accumulation during rain. A plurality of sprayers 207, mounted via hinges 208 for optimal positioning, is used to distribute the hydrophobic coating evenly across the entire bottom surface 201 of the mudguard 101.

Step G: Dispersing Anti-Rust Coating onto the Mudguard 101

[0097] In the final stage of the process, the system ensures long-term protection against corrosion by applying an anti-rust coating onto the mudguard 101 surface. This coating is automatically dispersed through a set of sprayers 207, connected to a multi-section chamber 102 containing the anti-rust solution. The sensing unit 301, equipped with optical sensor, continuously monitors the mudguard 101 for signs of oxidation. If early rust formation is detected, the system activates the anti-rust coating application process. The coating formulation neutralizes oxidation and creates a protective seal, preventing further corrosion.

[0098] The present invention works best in the following manner, where the system incorporated with the sensing unit 301 that detects moisture levels and mud accumulation using capacitive sensor and optical sensor mounted on a movable member 202 positioned near the bottom surface 201 of the mudguard 101. If significant mud adhesion is detected, the microcontroller processes the data and communicates with the Electronic Control Unit (ECU) to verify the vehicle’s driving condition. If the vehicle is in motion, the system blocks activation, displaying the dashboard alert instructing the user to bring the vehicle to stationary condition before cleaning operations commence. Upon activation, plurality of vibration units 203 generates high-frequency oscillations along the mudguard’s 101 surface, loosening adhered mud particles. To further enhance removal, the mud dispersant fluid stored in the container 206 sprayed through multiple openings 302 for breaking down stubborn debris. The sliding scrubber 205, mounted on parallel sliding units 204 moves across the mudguard 101, where arced brushes 204a scrub the entire width of the surface to remove loosened contaminants. For firmly adhered mud, the tapping arrangement 303, comprises of spring-loaded piston 303b reciprocated by rotating cam 303c, delivers mechanical impact force for ensuring complete debris removal. Once the mudguard 101 is cleaned, the hydrophobic coating is applied via rotatable sprayers 207, creating water-repellent layer that prevents future accumulation. Also, the sensing unit 301 via optical sensor monitors rust formation, and if detected, anti-rust coating is dispersed through sprayers 207 in view of forming protective barrier against corrosion.
