Method for automatically adjusting opening height of electric tail door of automobile
The invention discloses a method for automatically adjusting the opening height of an automobile electric tail door. In order to overcome the phenomenon that some short users cannot normally close the tail door due to the fact that the height of an automobile electric tail door cannot be automatically adjusted. The method comprises the following steps that a passenger manually operates a tail door button to trigger an electric tail door to be opened; the vehicle machine system obtains the distance A between a person and a vehicle tail through a middle reversing radar; the vehicle machine system actively opens a back-up image and recognizes the position B of the head of a person in the image; according to the data A and the data B, height data C is found in the calibration library and mapped to the corresponding maximum opening height D of the tail gate; and the vehicle machine system sends the maximum opening height D to the tail gate controller, and after the tail gate controller executes the maximum opening height D, opening is completed. The method has the advantages that the automatic adjustment of the maximum opening height of the electric tail gate is realized through a visual identification algorithm and a calibration method by utilizing a reversing image and a reversing radar of an automobile without adding an additional sensor, and the method has great flexibility and adaptivity.
本发明公开了一种汽车电动尾门自调节开启高度的方法。为了克服有汽车电动尾门不能自动调节高度，导致一些身高偏矮的用户无法正常关闭尾门的现象；本发明采用以下方法：乘客手动操作尾门按钮触发电动尾门开启；车机系统通过中置倒车雷达，获取到人和车尾之间距离A；车机系统主动打开倒车影像，识别画面中人员头顶位置B；通过数据A和B，在标定库中找到身高数据C，并映射到对应的尾门最大开启高度D；车机系统发送最大开启高度D给尾门控制器，尾门控制器执行后，完成开启。优点是利用汽车本身的倒车影像和倒车雷达，不需增加额外的传感器，通过视觉识别算法和标定方法，实现电动尾门开启最大高度的自动调节，具有很大的灵活性和自适应性。
