Abstract
A control system for controlling the damping force of a plurality of hydraulic dampers, each of which includes a damping force producing mechanism; a damping force adjustment member for adjusting the effective passage area of an oil passage in the damping force producing mechanism; an actuator connected to the damping force adjustment member; and an electrical power supply circuit for supplying electrical power to the actuator. The system includes: a first circuit for monitoring the operating time of the actuator and, when the operating time exceeds a first predetermined value, for forcibly moving the damping force adjustment member to a predetermined position by the actuator so as to thereby perform a forced damping force adjustment control and a second circuit for monitoring the operating time of the forced first circuit and, when the operating time of the first circuit exceeds a second predetermined value, for stopping the forced damping force adjustment control.
