    • The present disclosure relates to estimated road geometries used in vehicles, and in particular to a method and a control unit in a vehicle for determining a confidence level of an estimated road geometry. A method for determining a confidence level of an estimated road geometry is disclosed. The road geometry being estimated at least partly based on a position of a road object. The method comprises obtaining (S1) a reference position of the road object relative to the vehicle, updating (S3) a reach of a confidence zone of the vehicle, wherein a part of the estimated road geometry comprised within the confidence zone is associated with one or more reference confidence levels, and determining (S5) the confidence level of the estimated road geometry based on whether the reference position is comprised in the confidence zone.
    • 本公开涉及在车辆中使用的估计道路几何形状,特别涉及用于确定估计道路几何的置信水平的车辆中的方法和控制单元。 公开了一种用于确定估计道路几何的置信水平的方法。 至少部分地基于道路对象的位置来估计道路几何形状。 该方法包括获得(S1)道路对象相对于车辆的参考位置,更新(S3)车辆置信区域的距离,其中包括在置信区域内的估计道路几何的一部分与一个 或更多的参考置信水平,以及基于所述参考位置是否包括在置信区中来确定(S5)估计的道路几何的置信水平。
