(57) [Problem] To prevent overcharging of a power storage means by consuming electric energy stored in the power storage means without increasing the number of parts without affecting power output to a drive shaft. When the remaining capacity of a battery is equal to or greater than a predetermined value close to full charge, a motor that is not being driven among the clutch motor and the assist motor is determined based on a connection state of a first clutch and a second clutch. Find out. Then, only the d-axis current (field current) flows through the three-phase coil of the motor that is not driven. As a result, the electric energy stored in the battery 94 can be consumed due to copper loss of the motor and the like. In addition, since no q-axis current (torque current) is passed through the three-phase coil of the motor, no torque is output from the motor to the drive shaft 22 or the crankshaft 56, which affects the output of power to the drive shaft 22. There is no. |
