基于RFID车车通信的防碰撞预警系统设计

Design of an Anti-collision Early Warning System Based on RFID Vehicle-to-vehicle Communication

针对路边侧方位停车起步或车门开启时存在与道路上行驶车辆发生碰撞的问题,设计了基于无线射频识别(RFID)车车通信的防碰撞预警系统。停放车辆通过传感器收集自身转向车轮转动和车门开闭状态的数据,采用RFID技术将收集到的数据信息传输至附近道路的行驶车辆,经道路行驶车辆的电子控制单元(ECU)安全判别后,决定是否生成预警或相应驾驶辅助操作。经实验室模型车试验,验证了该系统的有效性。

Aiming at the problem of collisions with vehicles on the roadside when the parked car is started to drive-off or the door is opened by the vehicle passengers,an anti-collision warning system based on vehicle-to-vehicle communication is designed.The parked car collects its own road wheel movement and door movement data through sensors,and then uses radio frequency identification(RFID)technology to transmit the above data information to the moving vehicles on the nearby roads and the electronic control unit(ECU)of the moving vehicles on the nearby roads compared the data with the safe value to determine whether to generate an early warning or correlative driving assistance operation.The effectiveness of the system is verified by the model car tests in lab.
