PURPOSE:To improve initial responsibility, the riding comfortableness and travelling steadiness of a car even against continuous vibration by determining the rate of variation in hydraulic pressure on the each hydraulic pressure on compression and elongation sides in a variable damping force type shock absorber, and varying the damping force according to the above mentioned rate of variation. CONSTITUTION:Detecting means (a), (b) detect each hydraulic pressure on compression and elongation sides in a variable damping force type shock absorber respectively. Each output of the means (a), (b) is inputted into a controlling means C, which determines the rate of variation in the hydraulic pressure, and then computes control value to make the shock absorber turn into high damping force and to determine the value of the high damping force according to extreme value when the rate of variation has attained the extreme value, and to make the shock absorber turn into a fixed low damping force when the rate of variation has lowered to a fixed value. After that, operating means (d), (e) very the damping force on the compression and elongation sides in the shock absorber according to the output of the controlling means C respectively. |
