The invention relates to the technical field of automobile control, and provides an electronic outside rear-view mirror visual field adjusting method, which comprises the following steps: according to calibrated body data of a semitrailer truck, respectively carrying out kinematic model building on a tractor and a trailer, collecting steering wheel angle and vehicle speed information transmitted in real time, and calculating real-time angles of the tractor and the trailer in real time; the moving pixel value distance of the camera is calculated by combining the focal length and the pixel of the camera, the follow-up view adjustment of the semitrailer truck is realized by dynamically adjusting the display view range of the camera, a driver is kept in the view range capable of seeing the traffic condition at the tail of the truck all the time, and the safety of the truck is improved.
本发明涉及汽车控制技术领域,提供一种电子外后视镜视野调节方法,依据半挂货车标定的车身数据,然后分别对牵引车与挂车进行运动学模型搭建,采集实时传输的方向盘角度与车速信息,实时计算出牵引车与挂车的实时角度,进而结合摄像头的焦距、像素计算摄像头移动的像素值距离,通过动态的调节摄像头的显示视野范围,实现半挂货车的随动视野调节,保持驾驶员一直处于能够看到车尾交通状况的视野范围,提高车辆的安全性。
