Embodiment Construction

[0022] figure 1 A steering system for a motor vehicle is shown in diagrammatic form with a steering shaft 1 holding a steering wheel 2 at its upper end and a steering pinion 3 at its lower end. The steering pinion 3 meshes with the teeth on the rack 4 so that when the steering wheel 2 is turned, the rack 4 is displaced in its axial direction. A toothed rack is guided in a rack case 9 fixed to a vehicle structure 25 corresponding to the vehicle chassis. Tie rods 5 are attached to both ends of the rack 4 and are connected to knuckles 7 which in turn support steered wheels 6 . Thus, rotation of the steering wheel 2 causes the steering wheels 6 to pivot in a known manner. The steered wheels 6 contact the road surface 19 . A MacPherson strut unit 8 or similar biasing and damping unit fixed to the vehicle structure 25 corresponding to the vehicle chassis, allows linear movement of the steered wheels 6 to improve driver comfort, cushioning road undulations . Through this linear ...

Abstract

A method for operating an electromechanical steering system for a motor vehicle with variable chassis height, with a steering rack, which is driven by a servo motor through a recirculating ball screw drive, with a control unit, which receives input signals and generates output signals for driving the servo motor, the output signals being representative of an assist torque to be provided by the steering system, may be characterized in that, in operation, the control unit may receive or generate a chassis height signal that may indicate a current chassis height of the vehicle, and may limit the assist torque, on the basis of the chassis height signal, to an upper limit, wherein the upper limit may be decreased with an increase of the difference between the current chassis height and a mean chassis height.

Description

technical field [0001] The invention relates to a method for operating an electromechanical steering system for a motor vehicle, and a steering system for a motor vehicle. Background technique [0002] Known electric power steering systems are designed in such a way that the steering assistance is applied directly to a toothed rack by means of a recirculating ball screw drive, wherein the toothed rack is provided with a corresponding roller screw. As far as rack and pinion steering systems are concerned, the generally known principle is that the connection between the rack and the steered wheels is provided by a trackrod attached to the free end of the rack. Tie rods are also sometimes called tierods. The tie rods are not coaxially aligned with the rack, but at an angle relative to the axis of the rack. Thus, the force acting on the rack from the steering wheel via the tie rod has an axial component and a radial component with respect to the axis of the rack. The greater ...
