Abstract
A shock absorber control system controls vehicle shock absorbers by bringing them selectively into a softer dampening mode or a harder dampening mode in response to operation of a steering wheel of a vehicle. The shock absorbers are changed from the softer to the harder dampening mode only when the vehicle speed is higher than a reference vehicle speed and the steering wheel is turned at an angular velocity greater than a predetermined reference angular velocity. The angular velocity of rotation of the steering wheel is used as a parameter to select one of the softer and harder dampening modes only when the vehicle wheel has been angularly moved beyond a certain reference angle dependent on the vehicle speed. Therefore, no unwanted switching between the softer and harder dampening modes takes place when the steering wheel is angularly moved back and forth through relatively small angles. The harder dampening mode continues for a preset interval of time.
