PURPOSE:To improve the responsiveness of turn movement and the stability of straight running by controlling the steering angle direction of a rear wheel in response to the steering speed of a handle. CONSTITUTION:A judgment circuit 22 judges the size of the angular frequency of a handle, i.e., steering speed, based on the steering quantity signal inputted from a detection means 20. A control circuit 24 allows a rear wheel to generate the steering angle in the opposite direction to that of a front wheel and outputs the control signal generating the steering angle in response to the steering quantity signal when the steering speed of the handle is high based on the judged result of the judgment circuit 22 and the steering signal. On the other hand, when the steering speed is low, it allows the rear wheel to generate the steering angle in the same direction as that of the front wheel and outputs the control signal generating the steering angle in response to the steering quantity signal. |
