The invention provides a lane-level road condition obtaining method, device and equipment and a vehicle end navigation system, and the method comprises the steps: obtaining the road information of at least one road in a preset range for each high-precision track point in a vehicle driving track, and determining a first target lane matched with the high-precision track point based on the road information; acquiring adjacent high-precision trajectory points, predicting a plurality of selectable paths between the high-precision trajectory points and the adjacent high-precision trajectory points, and determining a target path from the plurality of selectable paths; aiming at a plurality of target paths of a plurality of high-precision track points in a preset time period, determining a target driving track, and acquiring lane matching information corresponding to the target driving track so as to determine a second target lane; acquiring lane-level road condition information according to the road condition information of the second target lane; thus, the accuracy and integrity of the vehicle path can be ensured, the road condition is closer to the actual state, and the accuracy of road condition acquisition is further improved.

    本申请提供一种车道级路况的获取方法、装置、设备及车端导航系统,包括:针对车辆行驶轨迹中的每个高精轨迹点,获取在预设范围内至少一个道路的道路信息,基于道路信息确定与高精轨迹点匹配的第一目标车道;获取相邻高精轨迹点,预测高精轨迹点与相邻高精轨迹点之间的多条可选路径,从多条可选路径中确定目标路径;针对预设时间段内的多个高精轨迹点的多个目标路径,确定目标行驶轨迹,获取其对应的车道匹配信息,以确定第二目标车道;根据第二目标车道的路况信息获取车道级路况信息;这样,本申请可以保证车辆路径的准确性和完整性,路况也更接近实际状态,进而提高了路况获取的准确性。
