STEERING DEVICE FOR VEHICLE

PURPOSE:To improve turning performance, by a method wherein, in a steering device which varies the steering angle of rear wheels, a change in steer due to a change in the roll angle of a vehicle during turn running can be effectively reduced through control of steering of the rear wheels. CONSTITUTION:During running of a vehicle, based on previously set data by means of output signals from front wheel steering angle sensor 13 and other sensors, computing process is effected by a computer 12 to obtain rear wheel steering information d0. From a detecting signal (s) proportioning the roll angle of the vehicle body detected from a roll angle sensor 14, based on previously set data, control information d1, which steers the rear wheels in a direction in which a fluctuation amount, equivalent to a steer amount produced by means of said roll angle, is obtained. According to control information d0+ or -d1 determined through addition of steering information d0 to the control information d1, an actuator 8 for steering the rear wheels is controlled.
