Power transmitted from an electric motor can be efficiently transmitted to a drive shaft while changing a shift state of a shift transmission means. In a hybrid vehicle 20, the engine 22 is stopped while the clutch C0 is engaged, and, for example, the transmission state of the transmission 60 is changed when the power from the motor MG2 is transmitted to the drive shaft 67 by the transmission 60. In order to transmit power from the motor MG1 to the drive shaft 67, the clutch C0 is released while setting torque commands to the motors MG1 and MG2 so that power based on the required torque Tr * is output to the drive shaft 67. In this state, the rotation speed of the motor MG1 is adjusted so that the motor MG1 can be connected to the drive shaft 67, and both the motor MG1 and MG2 are connected to the drive shaft 67 by the transmission 60, and the power is transferred from the motor MG2 to the motor MG1. And the connection between the motor MG2 and the drive shaft 67 by the transmission 60 is released. [Selection] Figure 1 |
