Vehicle suspension apparatus

Abstract

Abstract A vehicle suspension apparatus having a fluid spring chamber provided for each wheel and inserted between the wheel and a vehicle body, a fluid supply unit for supplying a fluid to each fluid spring chamber through a supply valve, a fluid exhaust unit for exhausting the fluid from each fluid spring chamber through an exhaust valve, a roll amount detector for detecting a roll amount of the vehicle body, and a roll controller for setting a control target corresponding to the roll amount detected by the roll amount detector and executing roll control in which the supply valves corresponding to the fluid spring chambers at a contracting side with respect to a direction of roll generated in the vehicle body and the exhaust valves corresponding to the fluid spring chambers at an expanding side are opened in accordance with the control target, includes a plurality of memories, provided in the roll controller, each for storing a control target corresponding to the roll amount of the vehicle body, the control targets stored in the memories being different from each other, and a selection switch for outputting a selection signal for selecting one of a plurality of memories in the roll controller to the roll controller, wherein the roll controller calculates a control target in accordance with one of the memories selected by the selection switch on the basis of the roll amount detected by the roll amount detector and executes the roll control on the basis of the obtained control target.
