PURPOSE:To restrain the rise of center of gravity at the time of turning by specifying relationships among each maximum and minimum control pressure of a hydraulic fluid in each hydraulic cylinder located at the inner and outer sides of turning, and the extent of a change rate in each pressure of the hydraulic fluid. CONSTITUTION:Each of hydraulic cylinders 18FL to 18RR fitted between a body side member 10 and each of front and rear, and right and left wheel side members 16 is controlled with a controller 22 via front and rear, and right and left pressure control valves 20FL to 20RR on the basis of each detected signal from a lateral acceleration sensor 24 and each of front and rear, and right and left vertical acceleration sensors 26FL to 26RR. In this case, the pressure control is so set that the hydraulic fluid pressure of a hydraulic cylinder at the inner side of turning will be a minimum control pressure at lateral acceleration equal to or more than the lateral acceleration value where the hydraulic fluid pressure of the hydraulic cylinder at the outer side of turning reaches a maximum control pressure. Also, when lateral acceleration is equal to or less than the aforesaid acceleration value, the rates of change in hydraulic fluid pressure at the inner and outer sides of turning are set to be equivalent to each other.
