ABSTRACT:
In a vehicular suspension a vertical acceleration of a sprung mass of a vehicular body and a relative speed between the sprung mass and an unsprung mass (viz., a wheel assembly) are detected. A sprung mass vibrating frequency is derived on the basis of detected vertical accelleration and relative speed, and a control unit determines whether the derived sprung mass vibrating frequency is equal to or higher than a predetermined dead frequency or not. The control unit outputs a control signal to the damper to change the damping force coefficient on the basis of the determination of whether the derived sprung mass vibrating frequency is equal to or higher than a predetermined dead frequency or not.
