Problems solved by technology

[0003] However, a possible problem with the use of active steering systems is that the steering wheel is not necessarily in the center position when the motor vehicle is moving straight ahead
Can be caused by production deviations, incorrect steering wheel or steering system settings, wear or damage
It is also possible that driving on a sideways lowering road causes an offset between the straight-ahead direction of the motor vehicle and the center position of the steering wheel
This deviation has a negative effect on driving comfort

Embodiment Construction

[0038] figure 1 Shown is a motor vehicle 1 comprising an active steering system according to the invention. The driver of the motor vehicle 1 controls the motor vehicle 1 via a steering wheel 2 and in this case turns the steering wheel 2 to a steering wheel angle 3 . In superimposed gear mechanism 4 , superimposed angle 6 provided by usually electric motor 5 is superimposed on steering wheel angle 3 . In a motor vehicle with front axle steering of the front wheels 9-1 and 9-2, the resulting total drive angle 7 causes the steering gear 8 to move, and the movement of the steering gear 8 produces the desired, wheels 9-1 to 9 Two of the -4 change in position. figure 1 The active steering system in has a device 10 for determining a steering wheel angle 3 , which detects the steering wheel angle 3 and transmits this angle 3 to a control unit 12 . Further, the active steering system of the exemplary embodiment comprises a device 11 for determining the directional movement of the m...

Abstract

A method for operating an active steering system of a motor vehicle 1 of the present disclosure may include the following steps of determining the driving state of the motor vehicle 1; determining the steering wheel angle (3) of a steering wheel (2) of the motor vehicle 1; determining the steering angle; determining an instant driver angle; determining the respective angle deviation, and calculating the correction angle of the steering wheel angle (3). Further, the present invention relates to the active steering system for the motor vehicle 1 and the motor vehicle 1 possessing the steering system.

Description

technical field [0001] The invention relates to a method for operating an active steering system of a motor vehicle, in particular to a method for correcting a steering angle error, also to an active steering system for a motor vehicle and to a motor vehicle having such a steering system. Background technique [0002] In active steering systems in motor vehicles, the steering angle of the steering wheel is set by a mechatronic assistance system. Typical examples of active steering systems are: steer-by-wire systems, in which there is no mechanical connection between the steering wheel and the steering gear of the wheels; and superimposed steering systems, in which the The steering angle is superimposed on the steering angle generated by the servo motor in a superimposition gear mechanism, and the sum of the two steering angles is transmitted to the steering gear of the wheels. The advantages of these steering systems include that the coupling between the angle of the steeri...
