Description:FIELD OF THE INVENTION

[0001] The present invention relates to an autonomous maintenance and cleaning system for public transport vehicles developed to automatically perform essential maintenance and cleaning functions upon detection of unoccupancy within the vehicle for ensuring passenger safety, operational reliability and efficient scheduling of maintenance and cleaning tasks.

BACKGROUND OF THE INVENTION

[0002] Public transport vehicles require to maintain high standards of cleanliness, operational safety and reliability to ensure passenger satisfaction and uninterrupted service. Vehicle maintenance and cleaning processes relies heavily on manual labor and scheduled inspections, which is inconsistent, time-consuming and prone to oversight. Additionally, the efficient detection of early faults reduces vehicle downtime. Hygiene has also become important, especially in shared spaces, where regular and thorough cleaning is necessary to maintain public health. Ensuring proper maintenance without manual intervention and operate safely in coordination to ensure well-maintained environment for passengers.

[0003] Traditional maintenance and cleaning of public transport vehicles involves tools such as mops, brushes, pressure washers, cleaning sprays, cloths, sewing kits, fabric scissors, staple guns, foam cutters, adhesive sprays, heat guns and replacement fabric or foam require significant manual effort, dedicated personnel to perform inspections to identify faults, clean interiors and carry out repairs. These tasks done with conventional tools are time-consuming, inconsistent and inefficient. Manual processes are prone to human error, overlook early signs of wear or damage and delay corrective action until after problems escalate. Cleaning large surfaces or hard-to-reach areas inside the vehicle is physically demanding and results in uneven sanitation. Similarly, routine inspections for engine health or seat damage lack real-time feedback, leading to reactive rather than preventive maintenance. These limitations highlight the need for a more efficient, solution that not only reduces physical labor but also improves the precision, speed and effectiveness of vehicle care and monitoring.

[0004] CN203713834U discloses a bus window cleaning device which comprises a T-shaped glass brush. The head of the T-shaped glass brush is provided with soft rubber, the upper surface of the head of the T-shaped glass brush is provided with a sprayer, a rod of the T-shaped glass brush is provided with a pneumatic water spraying box, the water outlet end of the pneumatic water spraying box is connected with the sprayer through a hose in the rod, the tail portion of the pneumatic water spraying box is provided with a hand-pressing handle, and the handheld end of the rod is provided with anti-slip threads. The bus window cleaning device is simple in structure, and water spraying and brushing can be carried out at the same time, so that water is saved and work efficiency is improved.

[0005] US5046251A discloses a low-cost hand-portable light-weight tool ideally suited for seamstress or upholster in domestic or commercial work, employing an electrical/heating-element of substantially known type of construction, into at least one blade member; whereby three species of the invention are set forth including variants thereof: a.) a scissor like embodiment, whereby the essential cutting and searing function is achieved under normal scissoring action by virtue of the oppositely closing blade's vertical shearing action relative to the opposed planar surface of the substantially thermoplastic fabric material, a species performing particularly effectively upon such fabrics having a proponderance of natural fibers in the weave, as well as ultra-sheer synthetic fabrics; b.) a fixed V-mouthed configuration similar to an opened scissor, therefore essentially relying upon a transversely moving manual thrust penetration into the fabric edge, generally more suitable for those heavier fabrics having a higher-percentage of thermoplastic-fibers in the weave; c.) a mono-bladed basic embodiment of the invention, whereby a handle portion includes a heating-tip having a fairly sharp blade edge which is directly applied anywhere upon the planar surface of the fabric, including a flat backing panel serving as a provisional working surface during the manual drawing procedure;-all three species serving to simultaneously cut and minutely sear those severed fibers so as to negate occurrence of fraying threads, and hence resulting in an exceptionally clean 'finished edge', ultimately saving the labor and expense involved in otherwise providing conventionally sewn seam construction.

[0006] Conventionally, many systems have been developed to perform cleaning, and maintenance in transport vehicles, but these existing devices lack full automation, real-time responsiveness and integration with passenger presence detection. They operate independently without coordinated control, leading to inefficient task execution, safety concerns and delayed fault detection. Additionally, they require significant manual input and cannot adapt dynamically to changing operational conditions or initiate preventive actions.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a system that requires to be capable of performing automatic cleaning, real-time monitoring and maintenance within public transport vehicles. Additionally, the system also needs to operate safely based on occupancy detection, reduce manual labor, minimize downtime, enhance hygiene and ensure early fault detection. This leads to improved efficiency, safety and reliability in daily transport operations with minimal human intervention.

[0024] The present invention relates to an autonomous maintenance and cleaning system for public transport vehicles that automates interior cleaning and seat restoration during unoccupied period and initiating corrective actions for significantly improving hygiene, preserving interior quality while ensuring a comfortable environment for passengers.

[0025] Referring to Figure 1, an isometric view of an autonomous maintenance and cleaning system for public transport vehicles is illustrated, comprising a continuous guiding rail 101 installed along an inner perimeter of a public transport vehicle, an internal imaging unit 102 mounted inside the vehicle, a dedicated water chamber 103 mounted on the guiding rail 101, a vertical slider 104 mounted on an outer front periphery of the water chamber 103, a telescopic rod 105 mounted on the slider 104 having a conduit 106, a pair of C-shaped plates 107 fitted with soft bristles 108 attached in front of the rod 105, a U-shaped wiping unit 109 mounted on the vertical slider 104, a panel 110 attached with guiding rail 101 via an extendable bar 111, a storage unit 112 configured with the panel 110, an automated foam dispensing unit 113 installed on the panel 110.

[0026] Figure 1 further illustrates a compressing unit 114 arranged around the outer periphery of the panel 110, a fabric roller 115 mounted on the panel 110 coupled with an integrated cutter 116, an adhesive applicator 117 installed on the panel 110, a telescopic vertical pole 118 mounted on the guiding rail 101 via a motorized ball-and-socket joint 119 fitted with a soft-bristled cleaning brush 120, a pneumatic link 121 suspended from the guiding rail 101 fitted with an array of sensors 122, a motorized air blower 123 is mounted on the guiding rail 101 and a vacuum-based cleaning unit 124 with a waste receptacle 125 integrated with the guiding rail 101.

[0027] The system disclosed herein comprises of a continuous guiding rail 101 that is installed along the inner perimeter of a public transport vehicle, seamlessly extending from the driver's cabin to the passenger compartment, serves as a stable base and core component of the system and is made from strong and lightweight materials which includes but not limited to hardened steel, Aluminum alloy, hard fiber and composite material to withstand weight, handle loads and irregularities, while providing a reliable foundation.

[0028] A user is required to initiate the operations in the manually by pressing a button installed on the public transport vehicle and linked with a processing unit associated with the system. The button is a type of switch that is internally connected with the system via multiple circuits that upon pressing by the user, the circuits get closed and starts conduction of electricity that tends to activate the system and vice versa.

[0029] An internal imaging unit 102 is installed with the enclosure work in synchronization with a laser sensor to detect and monitor presence of individual(s) within the vehicle. After system is activated by the user, the processing unit initiates a predefined sequence of operations by activating the imaging unit 102 which comprises an image capturing module including a set of lenses that captures multiple high-resolution images to detect and monitor the presence of individual(s) within the vehicle, then the captured images are stored within memory of the imaging unit 102 in form of an optical data. The imaging unit 102 incorporates a processor that is fed with an artificial intelligence protocol.

[0030] The artificial intelligence protocol operates by following a set of predefined instructions to process optical data and perform tasks autonomously. Initially, captured images are collected and input into a database, which then employs protocol to analyze and interpret the optical data. The processor of the imaging unit 102 via the artificial intelligence protocol processes the optical data and extracts the required data. The extracted data is further converted into digital pulses and bits and transmits to the processing unit.

[0031] An infrared sensor works by detecting changes in infrared radiation emitted naturally by human bodies, within their field of view, causes a sudden change in the IR radiation levels, which the sensor interprets as motion. The sensor then converts this thermal change into an electrical signal and further transmits to the processing unit, which integrates both data to verify the presence of individual(s) within the vehicle. The synchronization between the imaging unit 102 and the infrared sensor enhances reliability by cross-validating the data.

[0032] A telescopic vertical pole 118 is mounted on the guiding rail 101 via a motorized ball-and-socket joint 119 and is equipped with a soft-bristled cleaning brush 120, suitable for delicate surfaces such as interior walls, windows or ceiling panels of the public transport vehicles. when the vehicle remains stationary beyond a predefined duration such as at terminals or depots, the telescopic pole 118 actuates through a pre-programmed signal from the processing unit. The telescopic vertical pole 118 consists of nested tubular sections that slide within each other, connected to a pneumatic unit. Which includes an air compressor, a cylinder with a piston and solenoid valve. The air compressor generates compressed air, which passes through a solenoid valve and enters into the air cylinder. The air pressure inside the cylinder causes the piston to push the pole 118 outward, causing multiple nested tubular sections to extend for positioning the brush 120 to remove dust and debris.

[0033] The motorized ball-and-socket joint 119 provides full rotational freedom and precise angular control, enabling the brush 120 to reach multiple orientations and angles for effective coverage. The motorized ball-and-socket joint 119 includes a spherical ball enclosed within a socket and driven by multiple small electric motors, positioned orthogonally around the joint 119. Each motor is linked to the socket via gear train, allowing to apply torque to tilt or rotate the ball along specific axes. When the motor is activated by the processing unit, drives the gear train to push or pull against the ball’s surface, causing the ball to pivot or rotate within the socket to enable smooth multi-directional articulation of the brush 120 in confined or irregular spaces for cleaning interior surfaces of public transport vehicles.

[0034] A dedicated water chamber 103 is mounted on the guiding rail 101, features an internal heating element to warm water for cleaning purposes. The chamber 103 is thermally insulated to maintain water temperature efficiently and is connected to the processing unit that monitors vehicle occupancy through infrared sensor or imaging unit 102 and upon detection that the vehicle is unoccupied, activates the heating elements which works by converting electrical energy into heat through resistive heating, made of materials like nichrome and is integrated within base or sidewalls of the chamber 103. When activated by the processing unit, an electric current passes through the resistive coil, generating heat, which is transferred directly to the surrounding water to raise the temperature to a preset level suitable for cleaning or disinfection.

[0035] A cleaning module is integrated with the water chamber 103 to maintain the cleanliness of the vehicle's interior glass surfaces, particularly windows. The module includes a vertical slider 104 which is mounted directly onto outer front periphery of the water chamber 103 for allowing motion along the interior window surfaces, enabling the cleaning components to move up and down during cleaning. The vertical slider 104 comprises a motor coupled with a lead screw arrangement that converts rotational motion into precise linear movement, runs parallel to guide rails. The lead screw passes through a threaded nut fixed to a carriage which is also mounted on the guide rails to keep carriage aligned and stable during movement. Once the water is heated to a predefined temperature, the processing unit signals the motor to drive the lead screw, causing the carriage to move smoothly along the rails for ensuring smooth and stable movement to minimize lateral shifts or vibrations during cleaning.

[0036] A telescopic rod 105 is mounted on the vertical slider 104, integrated with a conduit connected to the water chamber 103, enabling warm water to be dispensed directly onto the vehicle's window glass surface to soften dirt and grime for more efficient cleaning. The rod 105 is extendable, allowing to adjust length for reaching various window heights and contours during dispensing. The telescopic rod 105 mentioned herein works by pneumatic unit that works same as above mentioned working of telescopic vertical pole 118.

[0037] A pair of C-shaped plates 107 are attached to the front end of the telescopic rod 105 to partially wrap around the curvature of the glass, ensuring broad surface contact without obstructing visibility or damaging delicate surfaces. Each plate 107 is densely fitted with soft, flexible bristles 108 to provide effective scrubbing action while preventing scratches. After water get dispensed, the processing unit signals the rod 105 to advance the C-shaped plates 107 toward the wetted glass surface. As the plates 107 glide across the surface, the bristles 108 gently agitate and lift dirt, stains and residue from the glass for effectively breaking up stubborn particles without causing wear. The curved design of the plates 107 ensures edge-to-edge coverage, reaching into corners and along the frame where dirt tends to accumulate.

[0038] The cleaning module also includes a U-shaped wiping unit 109 is mounted horizontally on the vertical slider 104 to perform thorough wiping and drying of the window glass surface. The U-shaped design ensures that even the edges and corners of the window receive effective wiping coverage. Along the inner periphery of the unit 109 is a strip of soft, rubberized fabric for high absorbency and gentle contact. After completion of scrubbing phase, the processing unit signals the vertical slider 104 to position the wiping unit 109 to align precisely with the curvature of the window, ensuring full contact across the surface during wiping. As the slider 104 moves in a controlled motion, the wiping unit 109 glides smoothly along the cleaned, wetted glass surface. The rubberized fabric efficiently absorbs excess water while collecting residual grime and streaks, leaving the glass clean and dry. The softness and flexibility prevent scratches, scuffs or damage to the vehicle’s glass. This ensures a clear, streak-free finish, enhances visibility and helps to extend the lifespan of the glass surfaces.

[0039] A seat repair module is mounted on the continuous guiding rail 101 to perform efficient maintenance and restoration of damaged passenger seats within the public transport vehicle. The repair module includes a panel 110 attached to the guiding rail 101 via an extendable bar 111, allowing the panel 110 to move along the rail 101 and extend toward the target seat when actuated by the pre-programmed signal from the processing unit upon detection of vehicle’s unoccupancy. The extendable bar 111 mentioned herein works by pneumatic unit that works same as above mentioned working of telescopic vertical pole 118. A storage unit 112 is integrated with the panel 110 that holds various seat repair components. These components are securely organized for quick access during repair.

[0040] An automated foam dispensing unit 113 is mounted on the panel 110 accurately dispenses foam into the damaged or worn seat cavity, restoring the seat's shape and structure. Once the repair module aligns with the damaged seat and the panel 110 is extended into position, the processing unit activates the foam dispenser to extrudes a controlled amount of foam at the affected area. The foam expands to fill voids, reshaping the internal structure of the seat.

[0041] A compressing unit 114 is installed around the outer periphery of the repair module’s panel 110 to apply uniform pressure to the foam after get dispense into the damaged seat area. Once the foam dispensing unit 113 has filled the cavity with expandable foam, the processing unit actuates the compressing unit 114 to press gently but firmly against the seat surface to conforms seat’s original contours, guiding the foam to set in the correct shape as cures. The applied pressure ensures the foam bonds securely within the damaged section, avoids bulging or irregularities, and restores the seat’s comfort and structure.

[0042] A fabric roller 115 is mounted at the bottom side of the seat repair module's panel 110 to provide replacement fabric to cover repaired areas. The roller 115 securely holds a roll of seat-grade upholstery material, which matches the original seat fabric in texture, flexibility, and durability. Once the foam has been dispensed into the damaged area and compressed into shape by the compressing unit 114, the processing unit signals the fabric roller 115 motor attached with a rotating spindle that holds a roll of fabric. When activated, the motor drives the spindle via a gear drive, allowing controlled unrolling of the fabric.

[0043] An integrated cutter 116 is positioned along the fabric path to cut the fabric to the exact dimensions needed to match the repair site. After fabric reached to required surface area for coverage, the processing signals motor, which is coupled to the cutter 116 via a gear drive, to perform clean and controlled cuts. This ensures precise edges and accurate sizing, reducing material waste and providing a seamless visual fit.

[0044] An adhesive applicator 117 is integrated on the panel 110 to apply bonding agent along the edges of fabric patches to ensure secure and lasting attachment to the repaired seat area. After the fabric roller 115 dispenses and the cutter 116 trims the patch to the required size, the processing unit activates the applicator 117 to apply a controlled line of adhesive along the perimeter of the patch, ensuring even coverage without overflow. Once the adhesive is applied, the fabric patch is positioned precisely over the repaired foam area and lightly pressed into place. This enhances repair consistency and helps maintain interior quality of public transport vehicles by ensuring each fabric patch is accurately sized and neatly applied, contributing to a professional finish and extending the lifespan of seating surfaces across the vehicle.

[0045] A vacuum-based cleaning unit 124 is mounted on the guiding rail 101 to withdraw waste and dust removal from the interior of public transport vehicles. The cleaning unit 124 activate by the processing unit during unoccupied periods as confirmed by the infrared sensor. The unit 124 consist of a compact waterproof electric motor connected to an impeller pump that generates suction through a suction nozzle. When powered by the processing unit, the motor spins the impeller to generate negative pressure for creating a steady suction force that pulls dislodged debris, dust particles and waste materials from seat restoration, floor edges and other hard-to-reach interior surfaces. The intake pathway leads to a waste receptacle 125 attached to the vacuum unit. The receptacle 125 is developed with filters to separate fine dust from larger debris, ensuring efficient containment and easy maintenance. This enables comprehensive interior cleaning that enhances hygiene standards and ensures the vehicle is consistently maintained for passenger comfort.

[0046] A pneumatic link 121 is suspended from the guiding rail 101 near the vehicle’s engine compartment serves as a flexible, retractable arm developed to assess critical engine conditions. The pneumatic link 121 mentioned herein works by pneumatic unit that works same as above mentioned working of telescopic vertical pole 118. The free end of the pneumatic link 121 houses an array of sensors 122 that includes a temperature sensor that monitors heat levels around the engine block, coolant lines and exhaust to detect abnormal rises or cooling inefficiencies and a sound sensor that captures acoustic signatures from the engine, analyzing for irregularities such as knocking, misfires or bearing wear. When the vehicle is designated for a maintenance check, the processing unit actuates the pneumatic link 121 to position the sensor array close to key engine components.

[0047] The temperature sensor disclosed above works on the Seebeck effect, where a voltage is generated at the junction of two dissimilar metals when there is a temperature difference between that sensing junction and the other reference junction, due to the difference in electron energy levels across the metals. This voltage is proportional to the temperature difference and is measured by the voltmeter, which is then then processed by the processing unit to monitor temperature levels of engine compartments in real-time, helping detect overheating and prevent component damage by enabling timely interventions.

[0048] The sound sensor disclosed above works by detecting pressure variations in the air and converting them into electrical signals. The sensor consists of a piezoelectric element that responds to sound vibrations. When sound waves hit the sensor, they cause diaphragm to vibrate. These vibrations are then converted into an electrical signal, which is processed by an amplifier and filtered to isolate the relevant frequencies, allows to detect acoustic sound from the engine that are not audible to the human ear, then resulting signal is transmitted to the processing unit for analysis. The collected data analyze by the processing unit for diagnostic evaluation. If thresholds are exceeded or anomalies detected, the processing unit alert the issue for review or triggers preventive maintenance actions.

[0049] A motorized air blower 123 is mounted on the guiding rail 101 to prevent engine overheating. The blower 123 is activated by the processing unit only when the engine temperature exceeds a predefined threshold as detected by the temperature sensor. The motorized air blower 123 works using an electric motor connected to a high-speed impeller housed within a blower 123 casing. When the motor is activated by the processing unit, rotates the impeller drawing in ambient air through an intake vent. The impeller's curved blades accelerate the air outward by centrifugal force, increasing both air pressure and velocity. This high-speed airflow is then directed through a nozzle towards engine. This targeted airflow accelerates heat dissipation, protecting engine components from thermal stress, reducing the risk of breakdowns and extending the engine lifespan.

[0050] A pressure sensor is integrated with a motion sensor and mounted on the vehicle’s brake pad to measure braking force and stopping time with high precision. The pressure sensor detects the amount of force applied to the brake pad during braking. The pressure sensor works, when quartz generate an electric charge in response to applied force. In the sensor, a piezoelectric quartz element is placed between two electrodes. When external pressure is applied, the deformation of the element produces a proportional electrical charge. This charge is then amplified and converted into a voltage signal by internal electronics and transmitted to the processing unit.

[0051] The motion sensor disclosed above detects movement by measuring changes in velocity or orientation. The core component is a Micro-Electro-Mechanical arrangement that contains a small mass suspended within a structure. When motion occurs, such as acceleration or deceleration, the mass shifts slightly due to inertia, causing a change in capacitance between the mass and surrounding electrodes. This change is converted into an electrical signal that represents the magnitude and direction of the motion. The signal is then processed by the processing unit to determine deceleration and stopping time during braking events. The processing unit analyzes both data to determine the braking efficiency by comparing applied pressure against deceleration response and stopping time. If discrepancies are observed such as increased stopping distance despite normal braking pressure or reduced force response—the processing unit interprets this as a potential sign of brake wear, pad degradation. In response, the processing unit issues a maintenance alert, recommending brake inspection before performance further deteriorates.

[0052] A force sensor integrated with an accelerometer, mounted on the accelerator pedal to assess the driver’s input consistency and detect potential engine or wiring faults. The force sensor works by converting force into a measurable electrical signal through the deformation of strain gauges bonded to a structural element called flexing element within accelerator pedal. When an external force is applied to the pedal, the flexing element deforms slightly, causing the strain gauges of thin conductive foils arranged in a grid pattern to stretch or compress. This deformation changes the electrical resistance of the strain gauges. The strain gauges are connected in a Wheatstone bridge configuration, which accurately detects small resistance changes and converts them into a voltage signal proportional to the applied force. This voltage is then amplified and interpreted by the processing unit to determine the magnitude of the force.

[0053] The accelerometer disclosed above measures acceleration forces by detecting changes in motion using Micro-Electro-Mechanical arrangement contains a small mass suspended by microstructures within a silicon chip. When the vehicle experiences acceleration, the inertial force causes the mass to shift slightly. This movement alters the capacitance between the mass and fixed electrodes. The change in capacitance is directly proportional to the amount of acceleration and is converted into an electrical signal by the sensor’s circuitry.

[0054] This signal is transmitted to the processing unit to determine the direction and magnitude of acceleration along one or more axes and helps monitor how consistently and quickly the pedal is pressed. The processing unit analyzes both data to determine throttle position, RPM change or torque output. If the processing unit detects a mismatch, such as strong pedal pressure with minimal or delayed engine response, indicate issues like throttle malfunction, wiring damage. Upon identifying such discrepancies, the processing unit issues an alert for diagnostic review.

[0055] An ultrasonic sensor is integrated with the guiding rail 101 serves to prevent collisions between the passengers or obstacles within the vehicle. The ultrasonic sensor works by emitting high-frequency sound waves from a transmitter module. These sound waves travel through the air until they encounter an individual, where they reflect back toward the sensor’s receiver. The sensor measures the time interval between emission known as the time-of-flight and uses this to calculate the distance to the individual based on the speed of sound in air. The sensor continuously sends and receives pulses, providing real-time distance measurements. When the sensor detects a presence within a predefined proximity, immediately sends a signal to the processing unit. In response, the processing unit halts ongoing operations and triggers the retraction of all extended components, primarily by moving them upward and away from the detected object. This retraction minimizes the risk of collision or injury.

[0056] The processing unit continuously aggregating data from a diverse sensor including temperature sensor, sound sensor, pressure sensor, accelerometers, and others to monitor engine and vehicle performance. As sensors data is transmitted to the processing unit, executes real-time analysis by comparing the incoming measurements against predefined performance levels and safety thresholds. For example, evaluates engine temperature levels, detects abnormal sound patterns indicative of faults, assesses braking force consistency, and monitors acceleration input accuracy. When the unit identifies deviations that suggest potential issues such as overheating, unusual vibrations, inefficient braking or inconsistent acceleration immediately flags these anomalies. Upon detecting such irregularities, the processing unit generates diagnostic alerts and transmits to a connected computing unit via a communication module, enabling technicians to intervene before minor issues escalate into critical failures.

[0057] The computing unit receives and processes these alerts in real-time, interprets the data, prioritizes issues based on urgency and notify maintenance personnel or trigger responses such as scheduling service appointments. The computing unit mentioned herein includes, but not limited to a smartphone, tablet or laptop equipped with a processor that receives data from the processing unit to store, process and retrieve output data in order to display on computing unit.

[0058] The communication module for establishing a wireless connection between the processing unit. The communication module used herein includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The communication module used herein is preferably a Wi-Fi module that is a hardware component that enables the processing unit to connect wirelessly with the computing unit. The Wi-Fi module works by utilizing radio waves to transmit and receive data over short distances. The core functionality relies on the IEEE 802.11 standards, which define the protocols for wireless local area networking (WLAN). Once connected, the module allows the processing unit to send and receive data through data packets.

[0059] A battery is associated with the system for powering up electrical and electronically operated components associated with the system and supplying a voltage to the components. The battery used herein is preferably a Lithium-ion battery which is a rechargeable unit that demands power supply after getting drained. The battery stores the electric current derived from an external source in the form of chemical energy, which when required by the electronic component of the system, derives the required power from the battery for proper functioning of the system.

[0060] The present invention works best in the following manner, where the system disclosed herein, comprises of continuous guiding rail 101 extending from the driver's cabin to the passenger compartment. The internal imaging unit 102 synchronized with the integrated infrared sensor, continuously detects passenger presence. When the vehicle is unoccupied, the dedicated water chamber 103 with the heating element supply heated water to the cleaning module. The cleaning module consists of the vertical slider 104 with the telescopic rod 105 connected to the water chamber 103 conduit, the C-shaped plates 107 with soft bristles 108 and the U-shaped wiping unit 109 with rubberized fabric performs thorough glass cleaning. The telescopic vertical pole 118 equipped with a soft-bristled cleaning brush 120 and motorized ball-and-socket joint 119 auto-deploys for interior cleaning during prolonged idling. The seat repair module mounted via the extendable bar 111 includes the storage unit 112 contains multiple seat repair components, the foam dispensing unit 113 to dispenses foam to damaged areas, the compressing unit 114 to compresses the foam into shape, the fabric roller 115 with integrated cutter 116 to cut-to-size fabric patches and the adhesive applicator 117 to apply adhesive on patches for automated seat restoration.

[0061] In continuation, the vacuum-based cleaning unit 124 collects waste into the integrated waste receptacle 125. The pneumatic link 121, positioned near the engine carries an array of sensors 122 with the temperature sensor and the sound sensor for real-time engine monitoring. The pressure sensor and the motion sensor on the brake pad assess braking performance, while the force sensor and the accelerometer on the accelerator pedal track input consistency.
