基于电子车牌的车辆追尾预警系统研究

Early warning system based on the electronics license plates of vehicles

针对行车安全中追尾以及盲区检测等问题,基于现有车载电子车牌,将射频识别技术(RFID技术)应用于前后相邻车辆之间距离、速度及加速度等关键参数的获取和动态变化分析。通过建立车辆各个运动状态下的动力学安全距离模型,对行车安全预警机理以及预警级别进行实时检测与分析。实验结果表明,基于RFID动态测距技术的车辆追尾预警系统能够提高行车安全性,根据不同级别的预警,提醒司机采取适当的行车措施,避免发生追尾事故的发生,减少国民经济损失。

For safety in the collision and blind spot detection, based on the existing vehicle electronic license plate, the dynamic range RFID technology is applied to detect the distance, speed and acceleration between adjacent vehicles according to the acquisition and dynamic changes of the key parameters, such as mechanism analysis. Through the establishment of vehicle under various motions of dynamic safety distance model, early warning mechanism and early warning on the traffic safety level in real-time detection and analysis. The experimental results show that the rear-end collision warning system based on RFID dynamic range technology can effectively improve the driving safety, according to different levels of the early warning system, remind the driver to take appropriate measures, avoid the happening of the accident and reduce the loss of national economy.
