PURPOSE:To eliminate a lag of adjustment of a ground clearance which is attributed to vibration of a vehicle by performing the adjustment of the ground clearance on the basis of an average value during monitoring of the ground clearance. CONSTITUTION:Suspension systems 1 through 4 are supplied with compressed air by the effects of opening-and-closing valves 7 and 8, a breathing valve 10 and a compressor 5 for adjusting the ground clearance. Responding to signals from potentiometers 12 through 15, a controller 20 controls those valves and a motor 6. The controller derives an average ground clearance during monitoring, on the basis of which it controls ground clearance. Even if the vehicle vibrates, the ground clearance may be adjusted without a lag. |
