Vehicle-mounted intelligent air conditioner control method and system based on fuzzy PID control

The invention relates to a vehicle-mounted intelligent air conditioner control method and system based on fuzzy PID control. The method comprises the following steps that an interior temperature of acurrent vehicle is collected; the interior temperature of the current vehicle is compared with a target temperature, so that a working mode is selected; a temperature difference value between the interior temperature in the vehicle and the target temperature is calculated; when the temperature difference value is larger than a first preset value, a working power of an air conditioner is output asa maximum working power of the air conditioner; when the temperature difference value is smaller than a second preset value, a working power of the air conditioner is output as a minimum working powerof the air conditioner; when the temperature difference value is larger than the second preset value and smaller than the first preset value, the temperature difference value is input as an input quantity of a PID controller,
