METHOD AND DEVICE FOR DETERMINING A POSITION OF A VEHICLE IN A ROAD NETWORK

A method is described in which a position of a vehicle is determined in a road network, having a plurality of edges, each of them being associated with a road section or a driving lane on a road section, by means of a sensor group of the vehicle, wherein first sensor data are detected by means of the sensor group, on the basis of the first sensor data each edge of a plurality of first edges of the road network is associated with a first probability that the vehicle is located in the road section associated with the first edge or in the driving lane associated with the first edge, second sensor data are detected by means of the sensor group, on the basis of the second sensor data and the probabilities associated with the first edges, a second probability is associated with each edge of a plurality of second edges of the road network that the vehicle is located in the road section associated with the second edge or in the driving lane associated with the second edge, and the second edge with the highest associated probability is determined to be the position of the vehicle.
