Abstract

A suspension apparatus of an automotive vehicle controls a posture of the vehicle body by controlling supply and discharge of an operating liquid to and from a cylinder unit interposed at each of the wheels between a sprung weight and an unsprung weight. The pressure within a high-pressure line for supplying the operating liquid of a high pressure to the cylinder units is released to the reservoir tank at a faster speed when a trouble occurs which cannot normally perform a control of the posture of the vehicle body and at a slower speed when an ignition switch has been turned off.
