    摘要： A motor drive-control device drive-controls a plurality of auxiliary devices with a single motor while securing a necessary capacity of the auxiliary devices side in correspondence with usage conditions. As such, in an air-conditioning system, necessary speeds of auxiliary devices such as a compressor and a warm water pump are calculated based on a necessary cooling capacity and a necessary heating capacity. The higher of these two necessary speeds is set as the motor speed for driving the auxiliary devices. The motor is thus controlled to this speed. Therefore, even if the air-conditioning heat load varies greatly due to changes in the usage environment, cooling and heating capacities necessary for air-conditioning temperature control can be obtained at all times.

    摘要： 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.

    摘要： An exhaust gas detoxifying system includes a catalytic converter in the exhaust system of an engine to detoxify exhaust gas. An air conditioner includes a compressor which is driven by the engine, and it performs air conditioning of the vehicle interior based on a refrigeration cycle. The operation of the air conditioner compressor is restricted depending on the degree of necessity of air conditioning, which is calculated from the difference between a vehicle interior temperature and a target temperature, if the catalytic converter exhaust gas detoxification performance is expected to deteriorate during accelerating or heavy-load operations of the engine.

    摘要： In an electric vehicle air conditioner, unpleasant compressor noise is reduced after issuance of an instruction to stop the operation of the air conditioner. An air conditioner controller calculates a delay time T1 from a map stored in a microcomputer in advance when an air conditioning switch or a blower switch is turned off and initializes a built-in timer to start counting. Thereafter, the speed of rotation of the coolant compressor (the speed of rotation of an electric motor) is decreased at the maximum rate of change of the speed of rotation through an inverter until the calculated delay time T1 passes. After the delay time T1 passes (after the counting by the timer terminates), the coolant compressor is stopped. The delay time T1 recorded in the map is set such that it becomes shorter with a decrease in the blower level.
