PROBLEM TO BE SOLVED: To accurately adjust an output of an engine at a time of actuating a compressor by using an existing sensor.SOLUTION: A compressor 54 is driven by an output of an engine. A pressure sensor 72 is provided to measure a downstream pressure of the compressor 54, a thermister 74 is provided to measure a downstream temperature of an evaporator 66, and a rotary encoder is provided to measure a rotational speed of the engine. A memory stores therein a plurality of graphs corresponding to a plurality of rotational speeds below a maximum rotational speed of the engine, respectively and each indicating a relation among the downstream pressure of the compressor 54, the downstream temperature of the evaporator 66, and an engine torque. An ECU adjusts the output of the engine at a time of actuating the compressor 54 on the basis of outputs from the pressure sensor 72, the thermister 74, and the rotary encoder and the plurality of graphs stored in the memory.SELECTED DRAWING: Figure 2

    【課題】コンプレッサの起動時におけるエンジンの出力を既存のセンサを利用して正確に調整する。【解決手段】コンプレッサ54は、エンジンの出力によって駆動される。圧力センサ72はコンプレッサ54の下流の圧力を測定するために設けられ、サーミスタ74はエバポレータ66の下流の温度を測定するために設けられ、ロータリエンコーダはエンジンの回転数を測定するために設けられる。メモリには、エンジンの最大回転数を下回る複数の回転数にそれぞれ対応し、かつコンプレッサ54の下流の圧力とエバポレータ66の下流の温度とエンジンのトルクとの関係を各々が示す複数のグラフが記憶される。ECUは、圧力センサ72,サーミスタ74およびロータリエンコーダの出力とメモリに記憶された複数のグラフとに基づいて、コンプレッサ54の起動時におけるエンジンの出力を調整する。【選択図】図2
