The invention discloses an automobile lane changing safety reminding auxiliary system. The system is characterized by comprising proximity radars installed on the left side and the right side of the tail of a vehicle, a speed measuring radar installed on the rearview mirror of the vehicle, a vehicle speed sensor arranged in the drive axle housing or transmission housing of the vehicle, LED lamps arranged at the left end and the right end of a middle rearview mirror in the vehicle, a left LED drive module, a right LED drive module, a data acquisition card and an MCU; the MCU calculates an initial front-back distance between an approaching vehicle and the vehicle according to the signals of an approaching radar; the MCU calculates the vehicle speed of the approaching vehicle according to thesignals of the speed measuring radar; and whether safe lane changing can be achieved or not is judged in the MCU based on the vehicle speed of the approaching vehicle, the vehicle speed of the vehicle and the initial front-back distance, and if the safe lane changing can be achieved, the MCU controls the corresponding LED lamps to work for reminding. Based on existing mature radar speed measurement and distance measurement technology and in combination with a reasonable data algorithm, a lane change safety condition can be intelligently judged.

    本发明公开了一种汽车变道安全提醒辅助系统,其特征在于:包括安装于车尾左、右侧的接近雷达,安装于本车后视镜的测速雷达,设置在本车的驱动桥壳或变速器壳内的车速传感器,设置在本车内中间后视镜的左、右端的LED灯,以及左、右LED驱动模块,数据采集卡,MCU。MCU中根据接近雷达的信号计算得到接近车辆与本车的初始前后间距;MCU根据测速雷达的信号计算得到接近车辆的车速;MCU中基于接近车辆车速、本车车速、初始前后间距判断是否可实现安全变道,若可实现安全变道则MCU控制相应的LED灯工作进行提醒。本发明基于现有成熟的雷达测速和测距技术,并结合合理的数据算法,能实现智能判断变道安全条件。
