PURPOSE:To make a precise body attitude control by making a pressure control valve for a fluid pressure cylinder control to be controlled in response to a lateral acceleration, force and aft acceleration, and rolling or pitching angular velocity. CONSTITUTION:When a detection signal is sent to a controller 22 from a lateral acceleration sensor 24 and up and down acceleration sensors 26FL-26PR, the controller 22 operates a lateral acceleration and rolling angular velocity, and determine a command signal respectively by a given procedure. Then command signals in response to the lateral acceleration and rolling angular velocity are added and operated right and left respectively, command signals for fore and aft, right and left each pressure control valves 20FL-20PR are prepared, each pressure control valve 20FL-20PR is controlled, and thereby each fluid pressure cylinder 18FL-18RR is operated. This constitution enables an attitude control to be stabilized with constraining occurrence of a self-excited vibration.
