PURPOSE:To improve controllability and comfortableness, in a suspension provided with a shock-absorber having variable damping force, by detecting the magnitude of disturbance of pavement during travel and varying the damping force of the shock-absorber. CONSTITUTION:Variation of vehicle height due to variation of pavement condition or load is taken out as a rotary amount of the shaft of a torsion bar 18, then it is transmitted through a link mechanism 19 to a vehicle height sensor 20. The vehicle height sensor 20 provides a vehicle height detection signal to a control unit 24 based on the rotary amount. The control unit 24 obtains a difference of vehicle height during when the vehicle is empty and when the vehicle is traveling and operates the variation of the difference thus providing a control signal for the damping force of shock-absorbers 2R, 2L, 3R, 3L. By such arrangement, control can be made with the magnitude of pavement disturbance being considered, resulting in the improvement of vibration suppressing performance and comfortableness. |
