The invention discloses a safety early warning method and system for vehicle door opening. The method comprises the steps that the opening and closing state of a rear seat vehicle door on the corresponding side is detected through a pressure sensor installed on an inner side door handle of the rear seat vehicle door of a vehicle; when it is detected that the backseat door is in the open state, an obstacle detection device installed on the backseat door on the corresponding side of the automobile is triggered to detect the obstacle condition behind the backseat door on the corresponding side; when the obstacle is detected, the obstacle type of the obstacle is identified according to the moving speed of the obstacle currently detected by the obstacle detection device; according to the type of the obstacle and the distance, currently detected by the obstacle detection device, between the automobile and the obstacle, the early warning prompt information is determined so that the automobile window display screen of the rear seat automobile door on the corresponding side can display the early warning prompt information, and therefore the situation that when the automobile door is opened, the automobile door/passengers collide with the rear obstacle is effectively avoided; and the opening safety of the vehicle door is ensured.

    本发明公开了一种车门开启的安全预警方法及系统,该方法包括:通过安装在汽车的后座车门的内侧门把手的压力传感器检测对应一侧后座车门的启闭状态;当检测到后座车门处于开启状态时,触发通过安装在汽车对应一侧的后座车门上的障碍物检测装置检测对应一侧后座车门后方的障碍物情况;当检测到有障碍物时,根据所述障碍物检测装置当前检测到障碍物的移动速度,识别所述障碍物所属的障碍物类型;根据所述障碍物类型和所述障碍物检测装置当前检测到所述汽车和所述障碍物的距离,确定预警提示信息,以使得对应一侧后座车门的车窗显示屏显示所述预警提示信息,从而有效避免车门打开时,车门/乘客与后方障碍物发生碰撞,保证车门开启的安全性。
