A control system controls a hybrid vehicle having an engine for rotating a drive axle, an electric motor for assisting the engine in rotating the drive axle, and electric energy storage means for supplying electric energy to the electric motor. The control system has an electric motor control unit which calculates an output power of the electric motor depending on an operating status of the hybrid vehicle and assists the engine based on the calculated output power of the electric motor. The electric motor control unit also reduces the output power of the electric motor when the rotational speed of the engine or the speed of the hybrid vehicle exceeds a predetermined value.
