An electric four-wheel drive vehicle and a control unit for the same, which can be applied to cars of class having larger displacements than the class to which the electric four-wheel drive vehicle equipped with the DC motor is applied, without increasing the cost over that of the known mechanical four-wheel drive vehicle. Front wheels of the vehicle are driven by an engine, and rear wheels are driven by an AC motor. A generator is driven by a rotating force of the engine to output DC power. An inverter converts the DC power outputted from the generator to AC power. A control unit controls the generator such that energy Pm required for driving the AC motor is outputted from the generator.
