PURPOSE:To improve the riding comfortableness of a vehicle by stopping the pitching prevention control and preferentially performing the level adjustment control and the nose-dive control when a predetermined time has elapsed from the start time of the pitching prevention control if a condition requiring the pitching prevention control to be performed is continued. CONSTITUTION:The right and left front wheel hydraulic cylinders 12, 10 are arranged between both end sections of front and rear axle housings and a chassis frame. When a condition requiring the pitching prevention control to be performed is continued after the pitching prevention control is started at the vertical acceleration of a vehicle of a predetermined value or more during the vehicle operation, whether a predetermined time has elapsed or not from the start time of this control is judged. When the predetermined time has elapsed, the pitching prevention control is stopped, and the preferential level adjustment control controlling the hydraulic cylinder expansion/shrinkage quantity within a specified value is performed. Or, the nose-drive prevention control preventing the sinking of the front section of the vehicle during braking is performed. |
