Beschreibung
Zusammenfassung:	A method and system for guiding a vehicle comprises a location module (26) for collecting location data for the vehicle. A vision module (22) collects vision data for the vehicle. A maximum allowable correction duration and a maximum allowable vision-derived displacement are established for correction of a position of a vehicle. A location quality estimator (24) estimates location quality data for the corresponding collected location data during an evaluation time window. A vision module (22) estimates vision quality data for the corresponding collected vision data during the evaluation time window. A selector (210) selects the application of location data or vision data based on the quality data and at least one of the maximum allowable correction duration and the maximum allowable vision-derived displacement for the evaluation time window or for an application interval trailing the evaluation time window.
