Abstract
A suspension apparatus has suspension units which have individual fluid spring chambers and are arranged on the wheels. When a detected negative acceleration (deceleration) exceeds a reference negative deceleration, front wheel fluid supply valves are opened for a control time T to supply a predetermined amount of fluid to the front wheel spring chambers and rear wheel fluid extent valves are opened for the control time T to exhaust a predetermined amount of fluid from the rear wheel fluid spring chambers, thereby decreasing nose dive at the time of deceleration.
