PROBLEM TO BE SOLVED: To suppress vibration of a hybrid vehicle that has an MG (motor generator) coupled to an engine MG so as to transmit power while suppressing pick-up response of an engine rotating direction when the engine is started.SOLUTION: The period from the starting of an engine 11 until when the engine rotating speed increases and gets stable within a predetermined range including a target engine rotating speed is determined as a starting state, and when the starting state is determined, command value correction is executed to correct a variation amount per unit time of an actuator (throttle, valve timing) command value according to a target output of the engine 11, so that an abrupt increase in engine rotating speed is suppressed. The engine rotating speed is gently increased by gently increasing a suction air amount of the engine 11 through the command value correction so as to suppress pick-up response of the engine rotating speed, and an abrupt increase in load torque of an MG 12 is suppressed so as to suppress vibration of the vehicle. |
