<p>PURPOSE:To simplify a control method and to improve control reliability by detecting a position with an analog sensor until the specified position is judged, and detecting the position after the specified position is judged with a second digital sensor. CONSTITUTION:In a rear-wheel steering control device, the steering angle of front wheels is detected with an analog type first front-wheel steering angle sensor 14 and a digital type second front-wheel steering angle sensor 15. When a front-wheel steering angle thetaF1 which is detected with the sensor 14 is within a specified value region with the neutral position as the reference and the sensor 15 outputs the signal, it is judged that the front wheels 17FL and 17FR are located at the neutral position. Until the neutral position is judged, the steering angle thetaF1 which is detected with the sensor 14 is selected, and the control is performed based on the steering angle thetaF1. After the neutral position is judged, the front-wheel steering angle thetaF2 which is detected with the sensor 15 is selected, and the control is performed based on the steering angle thetaF2. Therefore, the steering angles of the front wheels 17FL and 17FR can be detected highly accurately, and the control reliability can be improved.</p> |
