Abstract
The expanding/contracting accelerations of shock absorbers on a motor vehicle are detected and compared with preset accelerations, respectively, by an electronic controller, which individually varies the damping forces of the shock absorbers as a result of the comparison. The electronic controller corrects the preset accelerations so that the damping forces of the shock absorbers will be switched over at a uniform frequency or the damping forces of the front left and rear left shock absorbers and the damping forces of the front right and rear right shock absorbers will be switched over at a constant frequency.
