ELECTRIC POWER GENERATION CONTROL DEVICE

PROBLEM TO BE SOLVED: To improve vehicle energy efficiency.SOLUTION: An electric power generation control device 10 for controlling a motor generator 16 connected to an engine 13 includes: an engine control section 51 for stopping the engine 13 on the basis of a stop condition and restarting the engine 13 on the basis of a start condition; an electric power generation control section 53 for increasing target electric power generation voltage of the motor generator 16 when the engine 13 is restarted; and a threshold value setting section 54 for setting a threshold value on the basis of electric power storage amount of an electric power storage body connected to the motor generator 16 when the engine 13 is restarted. When electric power generation efficiency of the motor generator 16 is below the threshold value, the electric power generation control section 53 lowers the target electric power generation voltage that has been increased along with the restart of the engine 13.SELECTED DRAWING: Figure 2 【課題】車両のエネルギー効率を向上させる。【解決手段】エンジン１３に連結されるモータジェネレータ１６を制御する発電制御装置１０であって、停止条件に基づいてエンジン１３を停止させ、始動条件に基づいてエンジン１３を再始動させるエンジン制御部５１と、エンジン１３が再始動された場合に、モータジェネレータ１６の目標発電電圧を上げる発電制御部５３と、エンジン１３が再始動された場合に、モータジェネレータ１６に接続される蓄電体の蓄電量に基づいて閾値を設定する閾値設定部５４と、を有し、発電制御部５３は、モータジェネレータ１６の発電効率が閾値を下回る場合に、エンジン１３の再始動に伴って上げた目標発電電圧を下げる。【選択図】図２
