Abstract

To provide a vehicle drive device capable of effectively driving a vehicle by using in-wheel motors without falling into the vicious cycle between enhancement of driving via the motors and an increase in vehicle weight. The present invention is a vehicle drive device that uses in-wheel motors to drive a vehicle and includes in-wheel motors () that are provided in wheels () of a vehicle () and drive the wheels, a body side motor () that is provided in a body of the vehicle and drives the wheels of the vehicle, and a battery () and a capacitor () that supply electric power for driving the in-wheel motors and/or the body side motor, in which a voltage of the battery is applied to the body side motor and a voltage of the battery and the capacitor connected in series is applied to the in-wheel motors.
