The invention discloses an automobile door opening anti-collision early warning system and a multistage early warning method. A radar sensor is simultaneously connected with a vehicle-mounted entertainment host and an automobile body controller through a CAN bus, and the vehicle-mounted entertainment host is connected with a loudspeaker; and the vehicle body controller is simultaneously connected with the in-vehicle door handle sensor, the in-vehicle electronic lock and the door opening early-warning alarm indicator lamp. According to the invention, clear voice information is provided to replace buzzing sound, so that alarm information is clearer and easier to understand, and people in front and back rows of a vehicle can clearly receive an alarm state of door opening early warning; when the user neglects the alarm information and still continues to open the door, the vehicle door can be locked, and the user is forbidden to open the door from the interior of the vehicle. After the collision risk is relieved, the door opening forbidding function is relieved, and the user can operate a door handle in the vehicle to open the door to get off. Through the optimization, the collision risk can be more reliably avoided when the door of the vehicle is opened, and the safety of a driver and passengers and surrounding personnel is guaranteed.
本发明公开了一种汽车开门防碰撞预警系统及多级预警方法,雷达传感器通过CAN总线同时与车载娱乐主机和车身控制器连接,车载娱乐主机与扬声器连接;车身控制器同时与车内门把手传感器、车内电子锁、开门预警报警指示灯连接。本发明提供明确的语音信息代替蜂鸣音,使报警信息更加清晰易懂,并且让车辆前后排人员都能清楚的接收到开门预警的报警状态;当用户忽略报警信息后仍然继续开门时,能够将车辆车门锁住,禁止用户从车辆内部开门。当碰撞风险解除后,禁止开门功能解除,用户可操作车内门把手开门下车。通过上述优化,可以更可靠地避免车辆开门时发生碰撞风险,保障驾乘及周围人员安全。
