PROBLEM TO BE SOLVED: To suppress occurrence of booming noise or the like due to torque variation of an engine.SOLUTION: An ECU executes control processing including: a step (S102) of calculating a frequency fe and angle speed ωe when an operation point of an engine is within a predetermined region (YES in S100); a step (S104) of calculating torque variation amounts of the engine; a step (S108) of executing opposite phase torque control; a step (S110) of acquiring rotation speed of a MG; a step (S112) of calculating output shaft torque variation amounts; a step (S116) of calculating correction amounts when phase displacement is not equal to a threshold D or less (NO in S114): and a step (S124) of stopping control when the output shaft torque variation amounts are equal to a threshold B or less (YES in S118) and when the engine torque variation amounts are smaller than a threshold C (YES in S122).SELECTED DRAWING: Figure 8 |
