A compressor control device is presented to control driving power of a compressor of a vehicle air conditioner. The control device is composed of a first means which detects ambient temperature conditions of the vehicle, a second means which decides a necessary air-conditioning capacity according to the ambient temperature conditions and a third means which transmits driving power to the compressor from the engine when the necessary cooling capacity is larger than a reference capacity and from the electric motor when said necessary cooling capacity is not larger than said reference capacity.
