The invention discloses a steering wheel steering angle detection system which comprises a steering drag link sensor which is used for measuring position information of a steering drag link. The camera is used for monitoring and recording the position relation between the wheels and the vehicle body and shooting corresponding pictures; the picture processor is used for receiving and processing pictures shot by the camera and calculating the steering angle theta 2 of the wheels; the vehicle control unit is used for receiving data information sent by the steering drag link sensor and the picture processor, and processing and calculating the data to obtain a wheel steering angle theta; according to the invention, the accurate wheel steering angle can be calculated according to the structural relationship of the steering system and the angle between the wheel and the vehicle body. And the feedback is provided for a whole vehicle system to form good feedback so as to help better transverse control of the whole vehicle.
本发明公开了一种方向轮转角检测系统,包括转向直拉杆传感器,转向直拉杆传感器用于测量转向直拉杆位置信息;摄像头,用于监控记录车轮与车身位置关系,拍摄出对应的图片;图片处理器,用于接收摄像头拍摄的图片进行处理,计算出车轮的转向角度θ2;整车控制器,用于接收转向直拉杆传感器和图片处理器发出的数据信息,并对数据进行处理和计算得出车轮转向角度θ;本发明可以根据转向系统的结构关系及车轮与车身的角度计算出准确的车轮转向角度。提供给整车系统,形成良好的反馈,帮助更好的进行整车横向控制。
