Abstract

A motor/generator and drive wheel are connected to an engine, and the drive wheel is driven by the engine and motor/generator according to running conditions. A sensor which detects a slip of the drive wheel and a sensor which detects a depression of an accelerator pedal are provided, and the motor/generator is operated as a generator when the accelerator pedal is depressed and the drive wheel has slipped. Further, a spin of the drive wheel is prevented by increasing the rotation resistance of the motor/generator according to the frictional coefficient of the road surface.
