PURPOSE:To improve the steering stability by controlling working oil for supply and discharge into and from the oil chamber of a suspension cylinder to suppress variation in attitude of a vehicle when the vehicle is detected for acceleration, deceleration or turning thereof. CONSTITUTION:A wheel 3 is held by a chassis 1 via a suspension cylinder 4. Working oil is fed and discharged from and into the outside parts into and from upper and lower oil chambers 4A and 4B of a piston 4a inside the suspension cylinder 4 via a control valve 6. A control valve 6 is controlled by a control unit 8. In such equipment, the control unit 8 receives detected signals given from a stroke sensor 5, the pressure sensor 7 of the upper oil chamber 4A and a speed sensor 10. When acceleration, deceleration and turn of a vehicle is detected, the suspension cylinder 4 is controlled to suppress variation in attitude of the vehicle. |
