PURPOSE:To improve followability by decreasing the steering speed of rear wheels by a rear wheel steering device when the front wheel steering speed is low at the high car speed and increasing it when the front wheels steering speed is high at the low car speed. CONSTITUTION:The steering angle of the steering handle 6 of a steering device 2 is detected by a steering angle sensor 7, and a control means fed with at least the signal of this steering angle sensor 7 feeds a control signal in response to the front wheel steering angle to a pulse motor 5. A drive pulse frequency setting means outputs a signal increasing the drive pulse frequency of the pulse motor 5 when the car speed is low and relatively decreasing the drive pulse frequency of the pulse motor 5 when the car speed is high to the pulse motor 5 via the control means. |
