The utility model discloses a self-temperature regulation control device for a vehicle-mounted air conditioner. The self-temperature regulation control device for the vehicle-mounted air conditioner consists of infrared photoelectric switches, temperature sensors, stepping motors, wind shields, an electromagnetic clutch, a ventilation pipeline, an air inlet, air outlets and a microprocessor, wherein the infrared photoelectric switches are fixedly arranged at the positions of front and rear doors of a vehicle and are used for detecting the number of people who get on the vehicle and get off from the vehicle; the temperature sensors are placed at the front, middle and rear parts of the vehicle respectively; the stepping motors are placed on the side surfaces of the three air outlets respectively; the wind shields are mounted on the three stepping motors respectively. According to a working mode, the number of the people in the vehicle can be detected by the infrared photoelectric switches, the microprocessor outputs different PWM (Pulse Width Modulation) signals according to the number of the people in the vehicle, the signals control the separation and reunion of the electromagnetic clutch, and the start and stop of the compressor can be controlled, so that the aim of automatically regulating the temperature according to the number of the people in the vehicle is achieved; meanwhile, the quantities of air output by the three air outlets can be self-regulated according to the distribution situation of passengers in the vehicle, so that a greater amount of air can be supplied to a more crowded region, and a smaller amount of air can be supplied to a less crowded region.
