PURPOSE:To secure air intake/exhaust operation by a prescribed number of times for a prescribed period of time after an engine is stopped by keeping pressure less than a prescribed value in a reservoir tank even after an ignitions witch is opened. CONSTITUTION:Respective heights of front and rear wheels are independently detected by means of a front vehicle height sensor 23 and a rear vehicle height sensor 24, and thereby a front air spring 11 and a rear air spring 21 are independently adjusted via a front valve 12 and a rear valve 19. Once an Ig, SW is switched on, a vehicle height adjusting means 22 starts its adjusting operation to process input signals from a sensor 24 and a switch 20 for driving an exhaust valve 18, a reserve tank valve 13, and a rear side valve 19. The adjusting means further effects ordinary reinforcing operation without interrupting an engine operation provided the switch 20 is on when the Ig, SW is off, and stops the engine with the aid of engine stop means after the switch is put off. |
