The embodiment of the invention provides a positioning method and system based on vehicle-road cooperation, a medium and a vehicle-mounted device. The method is applied to a vehicle and comprises thesteps of when the vehicle is located in a preset area managed by a roadside device, receiving the positioning data broadcasted by the roadside device, wherein the positioning data comprises the coordinate values of the roadside device and the pseudo-range observation values corresponding to the roadside device; obtaining the pseudo-range observation value corresponding to the vehicle; according tothe positioning data, carrying out pseudo-range correction processing on a pseudo-range observation value corresponding to the vehicle to obtain a corrected pseudo-range observation value; and basedon the corrected pseudo-range observation value, calculating the corrected coordinate value of the vehicle. Therefore, the positioning precision can be improved.

    本申请实施例提供一种基于车路协同的定位方法及系统、介质和车载设备,应用于车辆,所述方法包括:在所述车辆位于路侧设备所管理的预设区域时,接收所述路侧设备所广播的定位数据,其中,所述定位数据包括:所述路侧设备的坐标值和所述路侧设备对应的伪距观测值;获取所述车辆对应的伪距观测值;根据所述定位数据,对所述车辆对应的伪距观测值进行伪距修正处理,得到修正后的伪距观测值;基于修正后的伪距观测值,计算出修正后的所述车辆的坐标值。如此,能够提高定位的精度。
