<P>PROBLEM TO BE SOLVED: To reduce cost by arranging so that an air conditioner electronic control means for an engine-driven compressor can be employed in a control system for an electric motor-driven compressor, without having a substantial design change made to the hardware configuration. <P>SOLUTION: A hybrid ECU 5 controls the rotation speed of a compressor electric motor 47. In this case, an output circuit, which outputs a driving signal for driving the compressor electric motor, only needs to be provided in the hybrid ECU 5. Therefore, when a hybrid vehicle or an electric vehicle is manufactured based on an engine vehicle, a large cost increase is not caused even if the output circuit is provided in the hybrid ECU 5, because it is a new additional part which should newly be designed and manufactured. In addition, the output circuit does not need to be provided in an air-conditioner ECU 7, thus solving the above problem. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
