The invention provides a vehicle rear-end collision prevention warning system based on license plate display signal reminding, and the system comprises a license plate body which is provided with a normal lamp and a warning lamp; a signal acquisition module which is used for acquiring the ambient light brightness of the vehicle, wherein the acquisition module is also used for acquiring the wheel rotating speed of the vehicle and the real-time distance between the vehicle and the two adjacent vehicles during following driving; a processing module which is used for adjusting the brightness of the normal lamp according to the ambient light brightness, wherein the processing module is further used for monitoring the distance between the front vehicle and the rear vehicle in real time according to the rotating speed of the wheels and the real-time distance and sending out a warning signal through the warning lamp when the distance between the front vehicle and the rear vehicle is smaller than the safe distance. According to the invention, the brightness of the normal lamp can be automatically adjusted according to the ambient light brightness, so the license plate information recognition degree is greatly improved; and when the distance between the front vehicle and the rear vehicle is smaller than the safe distance, the warning lamp can warn the rear vehicle, so that vehicle owners of the front vehicle and the rear vehicle can judge as soon as possible, and rear-end collision accidents of the vehicles are prevented.

    本发明提供一种基于牌照显示信号提醒的车辆防追尾警示系统,包括:车牌本体,所述车牌本体上设有常态灯和警示灯;信号采集模块,用于获取车辆的环境光亮度;还用于在跟驰行驶时,获取本车辆的车轮转速,以及所述车辆与相邻两车间的实时距离;处理模块,用于根据所述环境光亮度调整所述常态灯的亮度;还用于根据所述车轮转速和所述实时距离对前后车距进行实时监控,并在前后车距小于安全距离时通过所述警示灯发出警示信号。本发明可根据环境光亮度自动调整常态灯的亮度,极大的提高了车牌信息识别度;还可在前后车距小于安全距离时通过警示灯对后方车辆进行警示,以便前后车辆的车主及早进行判断,预防车辆追尾事故的发生。
