The invention provides an intelligent tripod for guaranteeing driving safety. According to the intelligent tripod, ambient light is reflected through a reflecting material, warning information is sent to a rear vehicle through a flicker lamp signal of an LED lamp strip, an anti-collision radar signal Rx1 of a rear coming vehicle is automatically detected when the vehicle encounters an emergency, the signal modulation feature of the signal is extracted, the Doppler frequency shift fd1 of the signal is estimated, and the anti-collision radar signal Rx1 of the rear coming vehicle is calculated. Then, an active anti-collision early warning signal Tx1 is generated and emitted, the Tx1 and the Rx1 have the same modulation characteristic and reversely compensate fd1 on the frequency, and propagation time delay caused by the early warning distance D1 is brought forward by two times on the time. By adopting the scheme of the invention, a virtual reflecting surface can be generated at a position D1 away from the accident vehicle, the signal of the rear vehicle anti-collision radar is reflected, and the anti-collision early warning and linkage functions of the rear vehicle anti-collision radar are triggered beyond the safety early warning distance, so that the driving safety, especially the driving safety of a highway, is ensured.

    本发明提供一种用于保障行车安全的智能三角架。该智能三角架除了通过反光材料反射环境光线,以及通过LED灯带的闪烁灯语信号向后车发出警示信息外,还在汽车遇到紧急状况时自动检测后方来车防撞雷达信号Rx1,提取其信号调制特征,估算其多普勒频移fd1,然后生成并发射主动防撞预警信号Tx1,Tx1与Rx1具有相同调制特征且在频率上反向补偿fd1、在时间上提前两倍预警距离D1引起的传播时延。采用本发明方案,可以在距离事故车D1处产生一个虚拟的反射面,反射后车防撞雷达信号,在安全预警距离之外就触发后车防撞雷达的防撞预警和联动功能,从而保障行车安全尤其是高速公路行车安全。
