The invention relates to a visual field follow-up method for an electronic rearview mirror of a commercial vehicle, and belongs to the technical field of vehicle safe driving assistance. The electronic rearview mirror at least comprises two cameras, two displays and one controller. According to the commercial vehicle electronic rearview mirror visual field follow-up method, images are collected through an electronic rearview mirror camera, signals such as the vehicle speed, the steering wheel rotating angle and the time transmitted by the whole vehicle are received in real time through an electronic rearview mirror controller CAN module, and the signals are analyzed through a hinge angle algorithm; the state of the hinge angle can reflect the form of the commercial vehicle in real time, the general position of the trailer in the view of the electronic rearview mirror is judged, and when the trailer is about to exceed the class-II view range, translation is conducted on the interception range of the class-II view through a self-built view follow-up algorithm, so that the trailer can be moved out of the class-II view range. Therefore, the image required by the driver is output, and the visual field follow-up effect is achieved. And the danger caused by a view blind area generated in the turning process of the commercial vehicle is avoided.

    本发明涉及一种商用车电子后视镜视野随动方法,属于车辆安全驾驶辅助技术领域。电子后视镜至少包括2个摄像机、2个显示器和1个控制器。本发明提供的一种商用车电子后视镜视野随动方法通过电子后视镜摄像机采集图像,通过电子后视镜控制器CAN模块实时接收整车传输过来的车速、方向盘转角、时间等信号,通过铰接角算法对这些信号的分析,计算出牵引车和挂车之间的铰接角,铰接角的状态可以实时反映商用车的形态,判定挂车在电子后视镜视野中的大体位置,当挂车即将超出II类视野范围时,通过自建的视野随动算法,对II类视野的截取范围进行平移,从而输出驾驶员需要的图像,达到视野随动的效果。避免商用车因转弯过程中产生视野盲区造成的危险。
