PURPOSE:To increase the response of the mean car height to the present car height and to secure a pleasant riding feeling constantly by making the level of the weight of the present car height to the past car height when the car is braked larger than that when the car is not braked, in the operation of the mean car height. CONSTITUTION:In shock absorbers 20 to 26 attached to suspensions responding to wheels 12 to 18, the damping property can be converted freely into two steps, the hard and the soft, by actuators 28 to 34 respectively, and the conversion is carried out by controlling electromagnetic switch valves 44 to 50 by a control device 58. In the case, the output signals of the car height sensors 52 and 54 are input to the control device 58, a mean car height to give specific weights to the past car height and the present car height respectively is computed, and when the deflection between the present car height and the mean car height exceeds a specific value, the hardness property is converted to the hard side for a specific period. When braking is detected, the level of the weight of the present car height to the past car height is set larger than that when the braking is not detected. |
