The invention discloses an automobile back door interactive opening and closing control method which comprises the steps that if an intelligent key enters a signal recognition area, a projection pattern is projected to a projection area, and the projection pattern is used for displaying a range capable of being treaded and recognized; projecting an infrared signal to the projection area, and calculating a user treading area proportion of the projection area treaded by the user according to whether the infrared signal of the projection area is shielded or not; judging whether the shielding duration of the infrared signal in the projection area exceeds a preset threshold value or not; if the user treading area proportion exceeds the threshold value and the duration of shielding of the infrared signals in the projection area exceeds the threshold value, a back door is opened; when the back door is opened, the intelligent key leaves the signal identification area, and the back door control system controls the back door to be closed.

    本发明公开了一种汽车后背门交互开关控制方法,包括:若智能钥匙进入信号识别区域内,向投影区域投射投影图案,投影图案用于显示可踩踏识别的范围;向投影区域投影红外信号,根据投影区域红外信号是否被遮挡计算用户踩踏投影区域的用户踩踏面积占比;判断投影区域红外信号被遮挡的持续时间是否超过预设阈值;若用户踩踏面积占比超过阈值并且投影区域红外信号被遮挡的持续时间超过阈值,开启背门;背门开启时,智能钥匙离开信号识别区域,背门控制系统控制背门关闭。
