PURPOSE:To prevent a body drift caused by a corrective steering by setting a corrective steering region in the reverse direction to a steering direction with the control steering angle set based on a present steering angle as the standard, and not conducting the supply and discharge of a pressure fluid when steering is made within the region. CONSTITUTION:When the detected values from a speed sensor 11 and a steering angle sensor 12 are inputted in a control device 9, a real steering for turning or a corrective steering is judged with a control steering angle setting means 13, and when the real steering, a steering angle is set to a control steering angle. And a lateral acceleration is estimated from a speed and a control steering angle with a lateral acceleration estimation means 14, moreover a roll angle is calculated with a calculation means 15, and thereby a pressure oil is supplied or discharged to or from a hydraulic cylinder via oil supply/discharge means 8a-8d. At that time, a corrective steering region is set in the reverse direction to a steering direction with the means 13, and the means 8a-8d are made unoperative in the corrective steering in the region. Thus a ride feeling can be improved. |
