The invention provides an automatic driving positioning method and device, computer equipment, a medium and a program product. The automatic driving positioning method comprises the following steps: acquiring map information of the position of a vehicle to obtain global path data for guiding the vehicle to run; applying vehicle positioning based on the vehicle driving process, and recording local vehicle positioning data in unit time as historical path data; matching the historical path data with the global path data to determine coarse positioning information of the vehicle based on position information provided by the matched global path data, therefore, the positioning precision of the vehicle in the driving process is not sharply reduced due to dependence on positioning modes such as wireless echoes and carrier phase differences under the condition of building shielding, so that the vehicle positioning precision meeting the automatic driving condition in various environments is provided for the vehicle.

    本公开提供了一种自动驾驶定位方法、装置、计算机设备、介质和程序产品。本公开的自动驾驶定位方法包括:获取车辆所在位置的地图信息,以得到用于引导车辆行驶的全局路径数据;基于所述车辆行驶过程应用车辆定位,记录单位时间内局部的车辆定位数据作为历史路径数据;通过所述历史路径数据与所述全局路径数据匹配,以基于匹配的全局路径数据所提供的位置信息确定所述车辆的粗定位信息,使车辆在驾驶过程中的定位不因依赖于无线回波、载波相位差分等定位方式在建筑物遮挡的情形下定位精度急剧下降,从而为车辆提供各种环境下符合自动驾驶条件的车辆定位精度。
