  • Method of damping the parasitic vibrations coming from the front axle assembly of a motor vehicle
    Patent number: 7379802
    Abstract: The invention relates to a method for motor vehicles provided with an electrical sero steering controlled by an electronic processor. The method comprises using an electrical signal within the processor which has at least one component image of the parasite vibrations coming from the front subframe. Said signal is filtered such as to isolate the component image of the parasite vibrations, from which a corrective value for the control current, which controls the electric servo motor for the steering, is calculated. The corrective value thus calculated is subtracted from the current control, determined by taking into account other parameters, to give a corrected control current, which gives to rise to an attenuation in the vibrations transmitted to the steering system and the steering wheel by acting on the servo steering.
