The invention provides a CMS visual field adaptive adjustment method. The method comprises the following steps: step 1, acquiring a reference pixel point coordinate of a target vehicle tail; 2, when it is judged that the vehicle is in the moving state, the current pixel point coordinates of the target vehicle tail are obtained; 3, the offset of the target vehicle tail is calculated; and 4, adjusting the CMS view angle according to the motion state of the vehicle, the offset and a third preset rule. The method is short in calculation link, simple in logic processing, high in accuracy and high in efficiency, not only can follow up during left-right turning, but also can follow up during uphill and downhill, expands the follow-up view range of the CMS rearview mirror, is wide in adaptability, and can be used by one section of trailer and also can be used by multiple sections of trailers.

    本发明提供CMS视野自适应调节方法,方法包括:步骤1、获取目标车尾的基准像素点坐标;步骤2、当判断车辆处于运动状态时,获取所述目标车尾的当前像素点坐标;步骤3、计算所述目标车尾的偏移量;步骤4、根据本车运动状态、所述偏移量及第三预设规则调整CMS视野角度。本发明的方法计算链路短,逻辑处理简单,正确率高,效率高,而且不仅可以在左右转弯时随动,还能在上下坡时随动,拓展了CMS后视镜随动视野的范围,并且适应性广,不仅一节拖车可以使用,多节拖车也可以使用。
