Vehicle drive device
View Patent ↗A vehicle drive device comprises an actuator located between an electric motor and axles for driving the vehicle, a built-in power source for supplying electric power to the actuator, and a control means for controlling the drive of the actuator. The built-in power source can be consisted of a battery, and the actuator can be consisted of an electromagnetic clutch. Here, the vehicle drive device further comprises a boost means, such as a DC-DC converter, for boosting voltage of the built-in power source such as the battery. The output voltage of the boost means is supplied electric power to the actuator such as the electromagnetic clutch. The output voltage of the boost means can be also supplied the electric power to the field coil of the electric motor.
