A method is provided for controlling a drive system andor a wheel braking system of a vehicle, in which a total braking power to be exerted on the wheels of a motor vehicle is composed of a drive braking power andor a wheel braking power. In valves such as these, the valve member typically includes a valve surface that contacts a valve seat included on the valve body when moving to its closed position. The method also entails applying a first section of a first elastic strand onto the first web and generally transversely to the web plane path and applying a second section of a second elastic strand onto the first web and generally transversely to the web plane path. An electromechanical sensor can be incorporated with at least a part of the cantilevered portion of the sensor member for sensing the vibrations of the sensor member caused by the precipitation, and generating an electrical response from which precipitation properties can be determined.
