Steering rack controlling method for e.g. electrical active front steering vehicle, involves replacing part of signal by temporally averaged part to obtain modified signal, where set point signal of rack is determined from modified signal

摘要

#CMT# #/CMT# The method involves delivering a signal representing an angular position of a flywheel and determining a position set point signal (SCC) of a steering rack from the delivered signal. A temporal average of a part of the delivered signal frequentially situated in an average frequency range is carried out by an averaging module (MMY). The part is replaced by the temporally averaged part in order to obtain a modified signal (S1M), where the position set point signal of the steering rack is determined from the modified signal. #CMT# : #/CMT# An independent claim is also included for a device for controlling a steering rack of motor vehicle, comprising a signal delivering unit. #CMT#USE : #/CMT# Method for controlling a steering rack of a motor vehicle such as electrical active front steering vehicle. #CMT#ADVANTAGE : #/CMT# The method permits to control the steering rack of the motor vehicle in a simple manner, thus avoiding risk of degradation of safety and comfortness of a driver of the vehicle during strong phase shifting of position setpoint signal of the rack. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view illustrating a steering rack controlling device.
