Method and device for determining a probability of a vehicle's presence in one of several lanes of a roadway

摘要

The invention relates to a method (200) for determining a probability (145) of a location of a vehicle (100) in one of several lanes (110) of a roadway (115), the method (200) comprising the one step of reading in (210) having lane data (127) representing a number of lanes (110) of a lane (115) traveled by the vehicle (100) and / or a possibility to switch between the lanes (110), and lane change data (137) representing one of represent a lane change of the vehicle (100) detected by a lane change sensor (135), and lane delimitation type data (141) are read in, which a type of a lane delimitation (143, 117) detected by a lane delimitation type sensor (137) of the lane currently used by the vehicle (100) ( 110) represents. The method (200) further comprises a step of linking (220) the lane data (127), the lane change data (137) and the lane delimitation type data (141) in order to determine a probability (145) of the vehicle (100) for one of several lanes ( 110) of the roadway (115) to be determined. Finally, the method (200) comprises a step of selecting (230) that lane (110) as the lane (110) in which the vehicle (100) is currently located and which has the highest determined probability of being (145).
