A vehicle includes an internal combustion engine that drives a first set of wheels, a generator, wherein the generator is powered by the internal combustion engine, a inverter connected to an output of the generator, an AC motor connected to an output of the inverter, and a controller, wherein the controller controls the generator, the inverter and the AC motor. The AC motor drives a second set of wheels. Power output by the generator is controlled according to a desired torque output for the second set of wheels. The controller calculates a potential power based upon the current status of the generator and controls the AC motor by the inverter based on the smaller of the desired torque and the potential power output of the generator.
