Embodiment Construction

[0026] exist figure 1 A steering device 10 for a motor vehicle is schematically shown in FIG. A wheel 20 is coupled directly to the steering element via a steering link arm 21. Depending on the design of the steering device 10 , a steering rod and a steering knuckle may also be provided.

[0027] An electronic steering assistance unit 22 is arranged between the steering element 12 and the actuating element 18 , which can generally be designed to assist the steering device 10 . This can include actively adjusting the actuating element 18 and generating torque in the steering element 12 in order to create an improved feeling on the part of the driver. The electronic steering assistance unit 22 can also actively return the steering element 12 when the vehicle transitions from cornering to straight-ahead driving.

[0028] exist figure 1 Only those components of the electronic steering assistance unit 22 that are required for the active return of the steering element 12 into it...

Abstract

A steering device (10) for a motor vehicle is described, which comprises a steering element (12) for steering the motor vehicle, and an actuating element (18) with which wheels (20) of the motor vehicle are adjusted depending on an actuation of the steering element (12). A steering support unit (22) is assigned to the steering element (12), in particular an electronic steering support unit for active resetting of the steering element (12), which comprises a motor (26) and an open-loop and closed-loop control unit (24) which actuates the motor (26) to generate a support torque. The open-loop and closed-loop control unit (24) receives data from a first sensor (28) which directly detects the position of the actuating element (18), and controls the motor (26) depending on the position of the actuating element (18). A method for controlling a steering device (10) is also described.

Description

technical field [0001] The invention relates to a steering system for a motor vehicle and to a method for controlling the steering system. Background technique [0002] Modern steering systems of motor vehicles are today typically electronically assisted, so that the steering torque exerted by the driver of the motor vehicle is amplified by an electronic steering assistance unit. As a result, the driver feels the steering of the motor vehicle as a whole more comfortable. The steering assistance unit can also generate a reaction torque, so that precisely at higher speeds an increased steering torque must be applied by the driver in order to steer. This contributes to operational safety. [0003] Typically, an electronic steering assistance unit has a reduction gear and an electric motor, which result in a certain friction and inertia of the steering device. In particular, the automatic and also desired centering behavior of the steering system, which is known to the driver...
