エンジン及びエアコンフアン制御装置。 A condenser fan is attached to the radiator and condenser installed in parallel to air-cool the condenser, and a radiator fan is also attached to air-cool the radiator and condenser, and the temperature is controlled based on the engine coolant temperature, air conditioner switch, and refrigerant pressure switch on/off. In the vehicle engine and air conditioner that control the respective rotation speeds of the radiator fan and condenser fan, a power transistor that controls the drive current of the radiator fan and the condenser fan, and a vehicle speed that inputs the vehicle speed and engine cooling water temperature are used. 1. A vehicle engine and air conditioner fan control device, comprising: an electronic control circuit for duty-controlling the power transistor with a duty that decreases as the power transistor increases.
