The invention discloses a method for automatically detecting and alarming foreign matters before closing a car door, which is characterized by comprising the following steps of: S1, when the car door is in an open state, acquiring an included angle between the car door and a door frame through an angle sensor arranged on the car door, and when the angle between the car door and the door frame is continuously reduced by a, detecting the foreign matters at the position of the car door in subsequent steps; s2, detecting the actual distance between a radar sensing device and the bottom of a door frame by using the radar sensing device mounted at the lower edge of the vehicle door; and S3, if the actual distance between the radar sensing device and the bottom of the door frame is smaller than the theoretical distance between the radar sensing device and the door frame, judging that foreign matters exist between the vehicle door and the door frame, and giving an alarm to prompt passengers. According to the method, foreign matter detection and alarm on the vehicle door position in the vehicle door closing process are achieved, and damage to the vehicle door and objects due to the fact that the vehicle door clamps the foreign matter is avoided.

    本发明公开了一种轿车车门关闭前异物自动检测报警方法,其特征在于:该方法包括以下步骤,S1、当车门为开启状态,通过车门设置的角度传感器获取车门与门框间夹角,当车门与门框之间角度连续减小a时,进行后续步骤的车门位置异物检测;S2、利用安装于车门下边缘位置的雷达感应装置,检测雷达感应装置与门框底部的实际距离;S3、若雷达感应装置与门框底部的实际距离小于二者之间的理论距离,则判断车门与门框之间存在异物,发出警报提示乘员。该方法实现了车门关闭过程中对车门位置的异物检测和警报,避免了因车门夹到异物对车门和物品造成的损伤。
