ABSTRACT:
A vehicle drive apparatus includes a battery that is a direct current power source, a converter that increases the voltage of the battery, an inverter connected to a motor that drives the vehicle, an inverter connected to a motor generator that functions as a motor or generator, and a motor control device that controls the motor. The vehicle drive device is also provided with a voltmeter, non-energized state determination devices that determine a non-energized state of the inverters, and ammeters that detect currents applied to a motor from each phase arm of the inverters. Signals of these devices and a signal from the non-energized state determination device are sent to the motor control device.
