Abstract

An object of the present invention is to provide a controller for an electric four-wheel-drive vehicle, which is capable of minimizing torque changes and consuming excessive power even when the excessive power is generated by a generator. A motor control unit causes an AC motor to generate desired torque by controlling an inverter. When the power generated by the generator exceeds the power consumed by the inverter and AC motor to generate excessive power, a current command determination unit in the motor control unit consumes the excessive power by increasing a loss in the AC motor.
