４輪操舵車両において、車速を検出する手段と、
後輪の操舵角度を検出する手段と、車速検出手段
よりの出力信号に基づく最大操舵角度と後輪操舵
角度検出手段よりの出力信号に基づく実操舵角度
とを比較して実操舵角度が最大操舵角度を超えた
場合に信号を出力する制御手段を設けたことを特
徴とする４輪操舵車両のフエイルセーフ装置。 In a four-wheel steering vehicle in which the rear wheels are steered in accordance with the steering of the front wheels, means for detecting vehicle speed;
The means for detecting the steering angle of the rear wheels compares the maximum steering angle based on the output signal from the vehicle speed detection means and the actual steering angle based on the output signal from the rear wheel steering angle detection means, and determines whether the actual steering angle is the maximum steering angle. A fail-safe device for a four-wheel steering vehicle, characterized in that it is provided with a control means that outputs a signal when the angle is exceeded.
