ABSTRACT:
In an apparatus for controlling a variable damping coefficient for at least one vehicular shock absorber, the shock absorber being interposed between a vehicle body and a tire wheel, an adjuster of the shock absorber which is so constructed as to change its position so as to provide an optimum damping coefficient for the shock absorber in response to a drive by means of an actuator (pulse motor), vehicle behavior detector which is so constructed as to detect a vehicle behavior, a damping coefficient control portion to derive an optimum damping coefficient according to the vehicular behavior, and a drive/control portion to form a drive/control signal to actuate the actuator, the drive/control portion is separated from the damping coefficient control portion and is integrally incorporated into the actuator. Furthermore, a fail safe circuit is integrally incorporated into the actuator, which is so constructed as to provide a predetermined fail safe drive for the actuator upon receipt of a signal indicating an occurrence of abnormality in either the damping coefficient control portion or drive/control portion from the damping coefficient control side.
