PURPOSE:To make a rear wheel turn-steering speed controllable at will, by driving a pulse motor with an interposal process carried out in accordance with an interposal pulse to be outputted to a rear wheel control device from a timer device. CONSTITUTION:A steering angle sensor 3 detecting a steering angle of a front wheel steering device 2 detects a turning angle in a steering wheel shaft with a solenoid pickup type sensor and outputs the signal to a controller 4a. Likewise, a signal out of a speed sensor 8 is outputted to the controller 4a as well. A rear wheel turn-steering device 5 is turned and steered with oil pressure being fed to a power cylinder 18 from a pump 19 via a rotary valve 20 operated by rotation in a stepping motor 6. Each signal out of the front wheel steering sensor 3, the speed sensor 8 and a rear wheel turn-steering angle sensor 9 is processed at the controller 4a, and with an output signal out of this controller, a stepping motor driving circuit 46 is driven, controlling the motor 6, thus rear wheel turn-steering takes place. |
