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 rearview mirror is composed of a left rearview mirror assembly and a right rearview mirror assembly. The rearview mirror assembly at least comprises a rearview mirror module, a regulator module, a control module, a CAN module and a power module. According to the visual field self-adaption method for the rearview mirror of the commercial vehicle, a rearview mirror controller CAN module receives vehicle speed, steering wheel rotation angle and time signals transmitted by the whole vehicle in real time, then the signals are analyzed through a hinge angle algorithm, and the hinge angle between a tractor and a trailer is calculated; the state of the hinge angle reflects the form of the commercial vehicle in real time, the general position of the trailer of the commercial vehicle in the view of the rearview mirror is judged according to the form of the commercial vehicle, and when the trailer is about to exceed the class-II view range, the angle of the lens in the class-II view range is adjusted through a self-built lens angle adjusting algorithm, so that the view follow-up effect is achieved, and the view follow-up effect is achieved. The danger caused by a view blind area generated in the turning process of the commercial vehicle can be reduced and 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。后视镜由左后视镜总成和右后视镜总成组成,后视镜总成至少包括后视镜模块、调节器模块、控制模块、CAN模块和电源模块。本发明提供的一种商用车后视镜视野自适应方法通过后视镜控制器CAN模块实时接收整车传输过来的车速、方向盘转角和时间信号,然后利用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,铰接角的状态实时反映商用车的形态,根据商用车的形态判定商用车的挂车在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,通过自建的镜片角度调节算法,对II类视野区域镜片的角度进行调整,达到视野随动的效果,能够降低避免商用车因转弯过程中产生视野盲区造成的危险。
