The invention provides a vehicle-mounted air filter self-cleaning system which comprises an electromagnetic directional valve, the input end of the electromagnetic directional valve is connected with the air outlet end of an original air compressor of a vehicle through a pneumatic triple piece, and the output end of the electromagnetic directional valve is connected with the input end of a vehicle-mounted pneumatic system and the input end of an air filter self-cleaning system. The air filtering self-cleaning system comprises an oil-gas filter, a speed regulating valve and an air filtering device, the input end of the oil-gas filter is connected with the output end of the electromagnetic reversing valve, the output end of the oil-gas filter is sequentially connected with the speed regulating valve and a first one-way valve in series and then communicated with the output end of the air filtering device, and the input end of the air filtering device is communicated with an external air source. The output end is connected with the input end of the air-conditioning ventilation system. According to the system, the filter element can be effectively cleaned in a relatively lossless mode through internal source compressed air, the filtering effect of the filter element is enhanced, and meanwhile the service life of the filter element is prolonged.
