To suppress generation of noise and vibration due to instable rotation of an internal combustion engine in starting a compressor, and to improve fuel consumption.SOLUTION: A compressor control device applied to a compressor operated by power of an internal combustion engine transmitted through an electromagnetic clutch, and starting the compressor by bringing a power transmission mechanism in a power transmission cutoff state, into a power transmission permission state, includes an estimation portion 120 estimating a cylinder internal pressure peak timing of a cylinder of the internal combustion engine on the basis of an operation state of the internal combustion engine, and a start control portion 130 determining a power transmission start timing for making the cylinder internal pressure peak timing and the start timing of the compressor, agree with each other on the basis of the cylinder internal pressure peak timing estimated by the estimation portion when a compressor start condition is established during the operation of the internal combustion engine, and executing a compressor start control to bring the power transmission mechanism into the power transmission permission state at the determined power transmission start timing.SELECTED DRAWING: Figure 3
【課題】圧縮機の始動時に内燃機関の回転が不安定になって騒音及び振動が発生することを抑制可能にすると共に燃費改善を図ることを可能にする。【解決手段】電磁クラッチを介して伝達される内燃機関の動力により作動する圧縮機に適用され、動力伝達遮断状態の動力伝達機構を動力伝達許容状態にさせることで圧縮機を始動させる圧縮機制御装置は、内燃機関の運転状態に基づいて内燃機関の気筒の筒内圧ピーク時期を推定する推定部120と、内燃機関の運転中において圧縮機始動条件が成立した場合に、推定部によって推定された筒内圧ピーク時期に基づいて、筒内圧ピーク時期と圧縮機の始動時期とを一致させる動力伝達開始時期を決定して、決定した当該動力伝達開始時期に動力伝達機構を動力伝達許容状態にさせる圧縮機始動制御を行う始動制御部130と、を備える。【選択図】図3
