The system creates a device for presetting a driver's desire for movement of the vehicle, coupled at least indirectly to an actuator of the internal combustion engine. According to the invention, the electric motors are operated as generators, at least upon release of the system for presetting a driver's desire. Drawn from the driven wheels by the electric motors is a first output portion that is generated in generator mode and fed to the electric machine for driving the internal combustion engine. The first output portion is selected such that the internal combustion engine operates at least at a speed of rotation greater than or equal to idling speed of rotation and at which the fuel supply is interrupted completely by means of a control coordinated with the internal combustion engine.
