PURPOSE:To carry out the running in the suspension state which is suited for a road surface state before a recessed and projecting state by providing returning means to return the suspension characteristics which has been altered by the suspension characteristics altering means for rear wheels to the original characteristics. CONSTITUTION:Levelling valves 151-154, are provided in a pair of air suspensions 3-6, and the opening or the closing between the supplying and exhausting system 200 for compressed air and the main air chambers 3b-6b of the suspensions 3-6 is carried out by the existence of electric conduction of electromagnetic solenoids 151a-154a. Signals from vehicle height sensors 1, 32 and a vehicle speed sensor 250 are input to a ECU 300, and the ECU 300 is inputted these signals to process its data, and it outputs a driving signal to the actuators 3d-6d of the air suspensions 3-6, the levelling valves 151-154, the motor 200a of the supplying and exhausting system 200 and a solenoid valve 200e, and after the processing is carried out, the suspension characteristics of the rear wheel is returned to the original characteristics when the rear wheels have already gotten over a recessed and projecting portion. |
