The invention discloses a vehicle-road cooperative positioning system and method. The vehicle-road cooperative positioning system comprises a roadside sensor unit, an edge calculation unit, a roadside communication unit, a vehicle-mounted communication unit and a vehicle-mounted calculation unit which are sequentially connected for data transmission, the vehicle-mounted calculation unit comprises a preprocessing module, a multi-target matching tracking module, a target position prediction module and a self-vehicle probability prediction module which are connected in sequence; and the vehicle-mounted calculation unit is used for positioning the vehicle in the road area according to the road side sensing information and the state information of the vehicle. The method can get rid of dependence on GNSS signals, can achieve long-distance continuous positioning of the networked vehicle, can obtain the relative position relation with surrounding vehicles, and is more practical.

    本发明公开了一种车路协同定位系统及方法。本发明车路协同定位系统包括依次连接进行数据传输的路侧传感器单元、边缘计算单元、路侧通信单元、车载通信单元、车载计算单元;车载计算单元包括依次连接的预处理模块、多目标匹配跟踪模块、目标位置预测模块、自车概率预测模块;所述车载计算单元用于根据路侧感知信息和车辆自身的状态信息在道路区域中定位车辆自身。本发明能够摆脱对GNSS信号的依赖,能够实现网联车辆的长距离连续定位,且能够获取与周围车辆的相对位置关系,更具实用性。
