PURPOSE:To prevent nose dive by feeding a fluid into front wheel side fluid spring chamber while discharging fluid out of a rear wheel side fluid spring chamber for a set time when the rate of change of vehicle speed is above a set rate of change during the operation of brakes. CONSTITUTION:As the brakes in operation is recognized from the signal of a brake switch 48, a controller 36 calculates the change in time in vehicle speed (the rate of change in vehicle speed) detected by a vehicle speed sensor 41 and, if the absolute value of the rate of change is increased, it obtains a controlling time from a vehicle speed change rate map. Then, in accordance with this controlling time, solenoid valves 223, 224 are operated to feed compressed air into front wheel side air spring chambers 11, 12 while operating solenoid valves 271, 272 to discharge compressed air out of rear wheel side air spring chambers 11, 12. Thereby, the front side of vehicle body is lifted up while lowering the rear side. By this structure, nose dive can be prevented. |
