PURPOSE:To adjust the height of two portions of a vehicle through a single pressure supply/discharge unit in accordance with the driving conditions, by providing a priority circuit in a control circuit to smoothly adjust the height of the vehicle even if the adjustment is opposite at the front and rear portions. CONSTITUTION:When the front portion of a vehicle is low and its rear portion is high, a detector 5F sends out a signal ''1'' and another detector 5R sends out a signal ''0'' and still other detectors 6F, 6R send out signals ''0'' so that the output of a NOR circuit 15 becomes ''1'' due to an OR circuit 12, an AND circuit 20, NOR circuits 13, 15 and a NOT circuit 14 and the outputs of a NOR circuit 28 and a NOR circuit 29 respectively become ''1'' and ''0'' due to NOR circuits 24-29 and an exclusive OR circuit 23. As a result, a pressurizer 22 acts and an actuator 8 for the front portion of the vehicle acts so that the pressurizer 22 supplies pressure to a pusher 7 for the front portion to adjust its height to a normal level. The smaller height is thus first adjusted prior to the larger height. |
