The following specification particularly describes the new or original invention and the complete manner in which it is to be performed.

TECHNICAL FIELD
[0001] The present disclosure relates, in general, to automobiles and more particularly, the present disclosure relates to a system and method for monitoring the condition and health of an air intake system of a vehicle.
BACKGROUND
[0002] An Air intake system (AIS) has significant impact on the performance of a vehicle's engine. The AIS directs air to the engine which requires oxygen for combustion. The engine delivers better performance when the intake system supplies clean, uninterrupted, and required amount of air to the engine. If dirt, debris, or other pollutants enter the engine, they begin to wear the components of the engine down. Thus, the AIS is intended to supply filtered compressed air to the engine of the vehicle.
[0003] The AIS comprises of an inlet duct (dirty side duct), an outlet duct (clean side duct), and an air filter. The primary function of the air filter is to remove dirt and other particles from the input air for providing purified air to the engine. When the air filter gets clogged up, the AIS may not be able to provide enough air to the engine. As a result, the engine would suffocate or end up using more fuel, resulting in inferior performance and lower fuel economy. Therefore, the air filter needs to be replaced when it gets too dirty. The filtered air from the AIS is monitored by the air pressure using a pressure sensor. When the air pressure of the filtered air reaches a particular threshold limit, it indicates that the air filter is too dirty and air filter element (air filter cartridge) needs to be replaced. In a conventional AIS, a warning to change the air filter element is provided to the user once the air filter element is chocked and reached it's acceptable working limit. However, the conventional AIS fails to provide real¬time information regarding the health of the air filter during its lifetime. Therefore, a user is unable to predict the remaining life of the air filter element and is required to change the air filter element as soon as possible after receiving the replacement warning. Moreover, conventional AIS fails to provide a warning in case of foreign particle, water ingress or leakage in the AIS. Foreign particle and water ingress be harmful to the engine as it may cause to destroy the engine. Also, leakage in the clean side duct of AIS leads to in dirty air inside the engine which leads to severe damage to the engine.

[0004] Presently, every vehicle has an Electronic Control Unit (ECU) embedded in a vehicle. The ECU is responsible for controlling one or more of the electrical systems or subsystems in the vehicle. The primary function of the ECU is to ensure that the engine runs smoothly. When the ECU identifies a problem with one of the vehicle's systems, the associated warning light is normally turned on to warn the user of the identified problem. However, conventional ECUs do not provide information regarding the remaining life of an air filter. Further, the conventional ECUs also fail to provide a warning in case of foreign particle, leakage, or water ingress in the AIS.
[0005] In view of the above, there exists a need to provide a system and method which overcomes the above-mentioned problems by providing information regarding foreign particle, water ingress, leakage, also providing the remaining lifetime of the air filter.
[0006] The information disclosed in this background of the disclosure section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

The ECU 115 may be configured to generate a lifetime indication alert corresponding to the determined pressure range.
[0036] FIG. 2 illustrates a block diagram of an air intake monitoring system 200, in accordance with some aspects of the present disclosure.
[0037] The air intake monitoring system 200 may include a memory 201, at least one controller 203, a pressure sensor 205, a warning module 207 and a communication module 209 in communication with each other. In one non limiting aspect, the at least one controller 203 may be electronic control unit (ECU) of the vehicle. However, the air intake monitoring system 200

is not limited to above hardware components and may comprise any other component for performing various other functions known to a person skilled in the art.
[0038] The communication module 209 may be configured to connect the air intake monitoring system 200 with one or more external components including the engine 113, etc. The communication module 209 may be configured to send and receive data via any medium known to a person skilled in the art. The communication module 205 may be configured to send and receive data via the connection established with the external components. The communication module 209 may comprise a transceiver.
[0039] The pressure sensor 205 may be coupled to the air intake system (AIS), as discussed in above aspects. The pressure sensor 205 may be configured to provide output pressure from the AIS to the at least one controller 203. The memory 201 is used to store a plurality of data including instantaneous threshold and a plurality of pressure ranges along with their respective lifetime indication.
[0040] In an aspect of the present disclosure, the at least one controller 203 may be configured to receive an output pressure of the air from the pressure sensor 205. The pressure sensor 205 may send the output pressure directly to the at least one controller 203 or send it via the communication module 205, as discussed in the above aspect.
[0041] The at least one controller 203 may be configured to monitor the output pressure of the air from the air filter 101. To monitor the output pressure, the controller 203 may first determine whether the monitored output pressure changes beyond a previous pressure, by the instantaneous threshold for a pre-determined time interval. The range for the instantaneous threshold may be retrieved by the at least one controller 203 from the memory. In one aspect of the present disclosure, the pre-determined time interval may be a time interval as known to a person skilled in the art. If the monitored output pressure changes beyond the previous pressure, by the instantaneous threshold, for the predetermined time interval, the at least one controller 203 may then be configured to generate a failure alert for a user of the vehicle. The failure alert is used to alert the user about water or foreign particle ingress which may cause significant damage to the engine of the vehicle. The failure alert may be communicated to the user of the vehicle by the warning module 207. The warning module 207 may be configured to generate an audio/visual cue for the driver/user of the vehicle, thereby preventing permanent damage to the engine.

[0042] In an aspect of the present disclosure, the at least one controller 203 may be also configured to determine if the monitored output pressure does not change beyond the previous pressure, by the instantaneous threshold, for the predetermined time interval. In this case, the at least one controller 203 may be configured determine whether the monitored output pressure falls within a pressure range of the plurality of pressure ranges for the predetermined time interval.
[0043] For the determination, the at least one controller 203 is configured to compare the monitored output pressure with the plurality of prestored pressure ranges to determine that monitored output pressure falls within one of the pressure ranges of the plurality of pressure ranges. The plurality of prestored pressure ranges may correspond to a remaining life of the air filter, which is determined by monitoring the lifecycle of plurality of similar type of air filters. In case the monitored output pressure falls within a pressure range from the plurality of pressure ranges, the at least one controller 203 is configured to generate a lifetime indication alert corresponding to the pressure range. The generated lifetime indication alert may be communicated to the user of the vehicle by the warning module 117 which receives the alert from the at least one controller 303 via the communication module 305. In one non-limiting aspect, the respective lifetime indication alert may have different type visual color indication.
[0044] Thus, the air intake monitoring system 200 facilitates lifetime indication of the air filter during different stages of usage of the filter, thereby allowing required maintenance to be taken up based on the condition of the air filter.
[0045] In one aspect, the at least one controller 203 may be embodied as a multi-core processor, a single core processor, or a combination of one or more multi-core processors and one or more single core processors. For example, the at least one controller 303 may be embodied as one or more of various processing devices, such as a coprocessor, a microprocessor, a controller, a digital signal processor (DSP), a processing circuitry with or without an accompanying DSP, or various other processing devices including, a microcontroller unit (MCU), a hardware accelerator, a special-purpose computer chip, or the like.
[0046] In one aspect, the memory 201 is capable of storing machine executable instructions. In an aspect, the at least one controller 203 is embodied as an executor of software instructions. As such, the at least one controller 203 is capable of executing the instructions stored in the memory 201 to perform one or more operations described herein. The memory 201 is also

capable of storing a plurality of data including the instantaneous threshold and plurality of pressure ranges including the pressure value for a fully functioning air filter 101 and the pressure value for replacement of the air filter 101 along with their respective lifetime indication alerts. The memory 201 can be any type of storage accessible to the at least one controller 303 to perform respective functionalities. For example, the memory 301 may include one or more volatile or non-volatile memories, or a combination thereof. For example, the memory 301 may be embodied as semiconductor memory, such as flash memory, mask ROM, PROM (programmable ROM), EPROM (erasable PROM), RAM (random access memory), etc. and the like.
[0047] FIG. 3 shows a flowchart illustrating a method 300 for monitoring an air intake system of a vehicle, in accordance with some aspects of the present disclosure.
[0048] As shown in fig. 3, at step 302, the method 300 discloses monitoring at predefined time intervals, a plurality of pressure values sensed by at least one pressure sensor. The at least one pressure sensor may be coupled to the output of the air filter. In one aspect, the output pressure measured at least one pressure sensor is received by the controller/ECU (as discussed in above aspect).
[0049] At step 304, the method 300 further discloses determining difference/change between a current pressure value and a previous pressure value for a predetermined time interval. In one non-limiting aspect, the ECU may retrieve an instantaneous threshold from the memory. At step 306, the method discloses determining whether monitored output pressure changes beyond a previous pressure by the instantaneous threshold for the predetermined time interval.
[0050] At step 308, if the current pressure value does not change beyond the previous pressure value, by an instantaneous threshold, for the predetermined time interval, the method 300 discloses determining whether the current pressure value falls within a pressure range of the plurality of pressure ranges for the predetermined time interval. Each pressure range of the plurality of pressure ranges is associated with a respective lifetime indication alert. For determining whether the current pressure value falls within the pressure range of the plurality of pressure ranges for the predetermined time interval, the method comprises comparing the current pressure value with the plurality of pressure ranges for determining whether the current pressure value falls within one of the pressure ranges of the plurality of pressure ranges.

[0051] At step 310, the method 300 discloses generating a lifetime indication alert corresponding to the pressure range for the user of the vehicle. The lifetime indication alert may be sent by the ECU to the user of the vehicle via the warning module, as discussed in above aspects.
[0052] In one non-limiting aspect, the method 300 discloses generating a failure alert for a user of the vehicle, if the current pressure value changes beyond the previous pressure value by the instantaneous threshold for the predetermined time interval. The failure alert is used to alert the user about water or foreign particle ingress which may cause significant damage to the engine of the vehicle. The failure alert may be communicated to the user of the vehicle by the warning module.
[0053] Thus, the method 300 facilitates monitoring condition of an air filter of a vehicle and providing a lifetime indication alert of the air filter to the user of the vehicle. Further, the method 300 facilitates providing a failure alert for a user of the vehicle, thereby avoiding significant damage to the engine in case of water or foreign particle ingress.
[0054] The method 300 may be described in the general context of computer executable instructions. Generally, computer executable instructions can include routines, programs, objects, components, data structures, procedures, modules, and functions, which perform specific functions or implement specific abstract data types.
[0055] The order in which the method 300 is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method. Additionally, individual blocks may be deleted from the methods without departing from the scope of the subject matter described herein. Furthermore, the method can be implemented in any suitable hardware, software, firmware, or combination thereof.
[0056] The disclosed method 300 with reference to fig. 3, or one or more operations of the flow diagram 300 may be implemented using software including computer-executable instructions stored on one or more computer-readable media (e.g., non-transitory computer-readable media, such as one or more optical media discs, volatile memory components (e.g., DRAM or SRAM), or non-volatile memory or storage components (e.g., hard drives or solid-state non-volatile memory components, such as flash memory components) and executed on a computer (e.g., any suitable computer, such as a laptop computer, net book, web book, tablet

computing device, smart phone, or other mobile computing device). Such software may be executed, for example, on a single local computer.
[0057] Furthermore, one or more computer-readable storage media may be utilized in implementing aspects consistent with the present disclosure. A computer-readable storage medium refers to any type of physical memory on which information or data readable by a processor may be stored. Thus, a computer-readable storage medium may store instructions for execution by one or more processors, including instructions for causing the processor(s) to perform steps or stages consistent with the aspects described herein.
