Abstract

A method for estimating the quality of localization using sensor detection, wherein the vehicle detects dynamic objects on the road and in the direct surroundings of the road and estimates the dimensions of the objects. The movement of these objects in the near future is estimated. The outer casings of these objects are entered into a map of the surroundings. From the perspective of the sensors used to detect the features in the surroundings, the limitations of the fields of view and the predicted temporal development thereof resulting from the movement of the transportation vehicle and the predicted movements of the objects are entered into the map of the surroundings. The surrounding features that have been entered into the map of the surroundings and which may at visible in the near future are determined. An upper limit for a measure of the quality of localization is estimated.
