It is an object of the invention to improve the utility of an electromagnetic absorber system which is disposed in a suspension system of a vehicle and which generates a damping force by a generation force of a motor. The electromagnetic absorber system 18 is equipped with high-speed-motion responding means, thereby obviating an insufficiency of the damping force and a deterioration of the controllability in a high-speed stroke motion. More specifically, a hydraulic absorber 64 is provided in combination with the electromagnetic absorber system such that the hydraulic absorber 64 operates in the high-speed motion in which an electromotive force of the motor 68 exceeds a power source voltage Further, two motors having mutually different T-N characteristics are provided, and the two motors are selectively operated depending upon a stroke speed. Further, a variable resistor is interposed between the motor and the power source, and a resistance value of the variable resistor is increased in the high-speed motion to realize a decrease in a time constant of the motor, etc. Moreover, to cope with a large extent of unevenness of a road surface, an active stroke motion is performed by a drive force of the motor, thereby preventing the high-speed motion from being performed.
