A method for the tuning of a steering wheel frame the rear of the torque and electromechanical force of a vehicle steering system

摘要

The invention relates to a method for the tuning of a steering wheel frame the rear of the torque of an electromechanical steering system, by means of which a vehicle steering wheel in a straight line leading back to the angular position is. The steering wheel return moment is set in accordance with a restoring function is set which is an instantaneous steering angle position is taken into account, for which the restoring function is designed in such a way that this resetting torques, with increasing deflection of the vehicle steering wheel angular position of the leading to a straight run-out increase the restoring function a for the polarity change of the return moment leading portion, the angular position provided for the traveling straight ahead, and this region provides for resetting torques from the maximum magnitude by the restoring function, which can be introduced into the restoring moments are relatively low inlet. A of the restoring function value supplied by an angle offset value is changed, whereby this angle offset value is adjusted so that the amount of the on the steering wheel steering wheel return torque perceived by the driver when driving straight ahead, below a threshold value is applicable. In this way, it is possible to operate an electromechanical steering system in such a way that, with a motor vehicle equipped with it in an advantageous straight running under with a on the part of the driver''s steering wheel which is felt as matching the rear of the control characteristics can be obtained. Furthermore, a to carry out the method given suitable electromechanical steering system.
