ABSTRACT:
When a sporadic shock due to a protrusion or sinking of a road surface is detected at front wheels of a vehicle during its cruising on the road surface, the characteristic of the rear wheel suspension of the vehicle is immediately altered to improve the controllability and the stability of the vehicle or the feel of the ride thereof. For that purpose, a height sensor for detecting the distance between the body of the vehicle and each of the right and left front wheels thereof, a judgement section by which a front wheel vehicle height signal generated by the height sensor is compared with a predetermined reference range signal, and a controller for altering the characteristic of the rear wheel suspension of the vehicle depending on the result of the comparison are provided. In addition, a returning control of the characteristic of the suspension to the original state immediately after the rear wheels of the vehicle have passed over the protrusion or sinking which causes a sporadic shock may be performed. More effective control can be performed if these section are provided for the right and left wheels of the front and rear of the vehicle, respectively.
