Abstract

PURPOSE:To improve reliability and responsiveness by forming a close-up so as to cause actual discharge pressure in a pressure control valve for attitude control to accord with operating pressure, and making it so as to release its slide motion at the time of something wrong in the pressure control valve, in case of a controller, bearing the above caption, which detects acceleration and performs the attitude control. CONSTITUTION:Each detected signal out of G sensors 55-57 is inputted into a controller 54 together with each signal of leveling sensors 58 and 59. The controller 54 calculates control pressure to be added to each actuator 29 for setting a vehicle attitude to the specified goal state on the basis of acceleration G to be inputted, while it drives a servo-solenoid 27, and controls a pressure control valve 31 for attitude control. And, actual pressure in a oil passage 49 is detected by a pressure sensor 30, finding its deviation with operating pressure by the controller 54, and something wrong in slide motion of the pressure control valve 31 is judged from the variation, and this abnormality outputs a slide motion releasing signal.
