To suppress a sense of incompatibility to be given to a user by suppressing occurrence of fluctuation in an actuation state of an electric load when performing engine stop control.SOLUTION: An engine stop control device 10 is applied to a system comprising an engine 70, a generator 30, a power source part 50, electric loads 55-57 and a switching part 40. The switching part 40 performs switching between a power generation state p1 where a power generating current of the generator 30 is output to a power supply path 29 and a reflux state p2 where the power generating current is returned within a closed circuit. The engine stop control device 10 executes engine stop control by generating power by the generator 30 in response to an engine stop request. The engine stop control device 10 determines whether the electric loads 55-57 are being actuated in the case where the engine stop request occurs. In the case where it is determined that the electric loads 55-57 are being actuated, the power generation of the generator 30 under the power generation state p1 is limited in relative to the case where it is determined that the electric loads are not being actuated, and causes the generator 30 to perform a braking operation under the reflux state p2.SELECTED DRAWING: Figure 1

    【課題】エンジン停止制御を行う際に、電気負荷の作動状態に変動が生じるのを抑制して、ユーザに与える違和感を抑制する。【解決手段】エンジン停止制御装置10は、エンジン70と発電機30と電源部50と電気負荷55〜57と切替部40とを備えるシステムに適用される。切替部40は、発電機30の発電電流が電源経路29に出力される発電状態p1と、発電電流が閉回路内で還流される還流状態p2とに切り替える。エンジン停止制御装置10は、エンジン停止要求に応じて、発電機30の発電によりエンジン停止制御を実施する。エンジン停止制御装置10は、エンジン停止要求が生じた場合において電気負荷55〜57が作動中であるか否かを判定する。そして、電気負荷55〜57が作動中であると判定された場合に、作動中でないと判定された場合に比べて発電状態p1下での発電機30の発電を制限し、かつ還流状態p2下で発電機30に制動動作を行わせる。【選択図】図1
