Compressor control system for vehicle air conditioner
First Claim
1. A compressor control system for an air conditioner of a vehicle, the vehicle includes:
- a driving electric motor for driving the vehicle;
a main battery for supplying electric power of a high voltage to the driving electric motor; and
a driving electronic control unit which has at least one of a function for controlling operation of an electric actuator driven when being applied with the high voltage of the main battery, a function for controlling a drive-power switching of the vehicle between the driving electric motor and an engine of the vehicle and a function for controlling a charge and a discharge of the main battery, the compressor control system comprising;
a compressor which is provided in a refrigerant cycle of the air conditioner for performing air-conditioning in a vehicle compartment; and
a compressor electric motor for driving the compressor, wherein the compressor electric motor has a rotation speed that is controlled by the driving electronic control unit.

Abstract
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.
