The invention discloses a rearview mirror-based vehicle door opening detection safety early warning system. The system comprises a long distance measuring radar, a door locking module, a short message alarm circuit, a user terminal and an electric control unit, according to the safety pre-warning system for detecting vehicle door opening based on the rearview mirror, the long distance measuring radar detects whether an object (a pedestrian or a vehicle) is close to the two sides of a vehicle body or not, measures the distance (S) and the speed (V) between the vehicle door and the moving object at the same time, and then sends the measured data to the electric control unit; after receiving the data, the electric control unit calculates a safe distance (S0) for opening the vehicle door by using the speed (V) of the moving object, and then compares the safe distance (S0) with the measured distance (S), and if the actually measured distance is greater than the safe distance (S is greater than S0), the vehicle door can be normally opened; and if the actually measured distance is smaller than the calculated safe distance (S is smaller than S0), the system automatically locks the automobile door and starts the sound-light alarm system, and the sound alarm module in the automobile gives out alarm sound.
本发明公开了一种基于后视镜检测车门开启安全预警系统,包括长测距雷达、锁门模块、短信报警电路、用户终端和电控单元,此基于后视镜检测车门开启安全预警系统长测距雷达先检测车身两侧是否有物体靠近(行人或者车辆)同时测出车门与行进物体的距离(S)与速度(V),之后将测得数据送入电控单元,电控单元在接收到数据后利用行进物体的速度(V)计算出打开车门的安全距离(S0),然后与测得的距离(S)进行比较,如果实测距离大于安全距离(S>S0)车门能够正常的打开,如果实测距离小于计算出的安全距离(S
