In a power output apparatus including two electric motors and a transmission transmission means, both of the two electric motors are connected to a drive shaft by the transmission transmission means to continuously obtain a relatively large torque. In a hybrid vehicle 20, when traveling in a two-motor traveling mode in which both of motors MG1 and MG2 are coupled to a drive shaft 67 by a transmission 60, the required torque Tr * set in step S110 is obtained. , The torque commands Tm1 * and Tm2 * for the motors MG1 and MG2 are such that the sum of the loss of the motor MG1 and the loss of the motor MG2 is minimized and the power based on the required torque Tr * is output to the drive shaft 67. Is set (steps S130 to S150). [Selection] Figure 12 |
