PROBLEM TO BE SOLVED: To control the occurrence of a torque change in an electrical rotating machine when an inverter is stopped.SOLUTION: A control device executes programs including a step (S108) for executing boosting target increase control if an inverter is stopped by abnormality of an electric circuit including the inverter (S100:YES) and a counter-electromotive voltage Vr generated in a second MG is higher than a system voltage VH (S102:YES), a torque estimation value is substantially zero (S104:YES) or a vehicle is in an acceleration and deceleration state (S106:YES), and a step (S110) for executing normal boosting control if the counter-electromotive voltage Vr is lower than the system voltage (S102:NO), the torque estimation value is not zero (S104:NO) or the vehicle is not in the acceleration and deceleration state (S106:NO). |
