Abstract
According to the present invention, as soon as the sporadic protrusion or sinking of a road surface is detected at the front wheel of the vehicle during its running on the road surface, the air chambers of the air suspensions for the right and the left rear wheels of the vehicle are connected to each other to alter the spring constant of the rear suspensions to `soft` when the rear wheel passes over the sporadic protrusion or sinking of the road surface, so that the feel of ride of the vehicle and the controllability and stability thereof are kept good. After the rear wheel moves over the sporadic protrusion or sinking, the characteristic of the rear suspensions is returned to the original state appropriate to the normal running state of the vehicle. Detectors for the sporadic protrusion or sinking of the road surface may be provided for the right and the left front wheels of the vehicle, respectively. The rear suspensions of the vehicle can be more appropriately controlled by that.
