[0002] In the existing technology, the radiator is usually self-cleaned by controlling the fan to reverse at the highest speed through the vehicle controller VCU by transmitting PWM signals when the vehicle is powered on. This method mainly performs a self-check when the vehicle is powered on, and the vehicle controller VCU transmits a PWM signal to the fan to reverse the fan at full speed for a period of time to achieve the purpose of self-cleaning.
