Claims

[Scope of utility model registration request]

A fluid spring chamber provided for each suspension unit that supports each wheel, a fluid supply means for supplying fluid to each of the fluid spring chambers through a supply valve means, and a fluid discharge from each of the fluid spring chambers. a fluid discharge means for discharging fluid through a valve means; a roll amount detection means for detecting the amount of roll of the vehicle body; roll control means for driving the supply valve means and the discharge valve means so as to supply a set amount of fluid to the fluid spring chamber of the suspension unit and to discharge a set amount of fluid from the fluid spring chamber of the suspension unit on the extension side; In a vehicle suspension system that has a vehicle height adjustment function that raises and lowers the vehicle height by supplying and discharging air to the fluid spring chamber of each suspension unit, a G sensor that detects the horizontal acceleration G generated in the vehicle body is used. , means for suspending the vehicle height adjustment when the lateral acceleration G detected by the G sensor is equal to or higher than a set value.
