PURPOSE:To widen the width of maneuverability control by dividing a yawing motion and a lateral motion, setting their target values separately, and performing the steering angle control of wheels so as to realize the target values. CONSTITUTION:Front and rear wheel steering devices 4, 5 are constituted with a solenoid driver 21, a control valve 22, and an oil pump 26. The control value 22 is provided with oil paths 28, 29 communicated to the right and left hydraulic chambers 34, 35 of hydraulic steering devices 6, 7 and has a spool valve 25 adjusting the operating oil flowing into these oil paths 28, 29. The solenoid driver 21 feeds an electric current signal proportional to the front and rear steering angle target values deltaF, deltaR provided by a microcomputer 1 to one of the right and left solenoids 23, 24, thereby the spool valve 25 is switched, and steering devices 6, 7 are operated. |
