In a compressor control system for a vehicle air conditioner, a hybrid ECU of the vehicle controls a rotation speed of a compressor electric motor. In this case, an output circuit, which outputs a driving signal for driving the compressor electric motor, only needs to be newly provided in the hybrid ECU when a hybrid vehicle or an electric vehicle is manufactured based on an engine vehicle. Therefore, a high cost is not caused even when the output circuit is provided in the hybrid ECU which should be newly designed and manufactured. In addition, because the output circuit does not need to be provided in an air-conditioning ECU which is an existing component of the engine vehicle, the air-conditioning ECU in the engine vehicle can be directly applied to that in the hybrid vehicle without a substantial hardware change. Therefore, design cost can be reduced.

In a first forward drive mode, at speeds of the vehicle lower than a predetermined speed, an electric traction motor (17) drives the wheels (12, 13) of the vehicle, while an internal-combustion engine (27) drives an electric generator (34) or rests. The generator charges an electric battery (38), or powers the traction motor, or both. In a second forward drive mode, at speeds of the vehicle higher than the predetermined speed, the engine drives the electric generator and the wheels of the vehicle, while the traction motor is not energized. In a third forward drive mode, at speeds of the vehicle higher than the predetermined speed, the traction motor, powered by the electric battery, together with the engine drive the wheels of the vehicle. In a reverse drive mode the traction motor alone drives the wheels of the vehicle. A clutch (32) selectively interrupts the power transmission between the engine and the wheels of the vehicle. The traction motor selectively operates as an electric braking generator, during speed retardation and braking of the vehicle, and charges the electric battery.

A vehicle air conditioner includes an air conditioning case, a blower fan for blowing conditioned air into a passenger compartment, and an evaporator disposed in the air conditioning case. The air conditioning case has a cooling opening upstream from the evaporator, so that at least inside air is blown by the blower fan to vehicle electronic units through the cooling opening.

Further, because at least inside air, without being cooled by the evaporator, is blown to the electronic units, the electronic units can be prevented from being excessively cooled. Accordingly, it can restrict the surface temperature of the electronic units from reducing less than a dew point, thereby effectively reducing condensed water on the electronic units.
