Abstract
A method for wrong-way driver detection, including a step of reading in position data via an interface, the position data representing a measured position of a vehicle, a step of reading in map data mapping road segments negotiable by the vehicle, a step of reading in a plurality of particles, one particle representing an assumed position of the vehicle and a weighting assigned to the assumed position, and a step of determining a deviation between the plurality of particles and the measured position represented by the position data, using the map data.
Claims17
A method comprising:
- reading in position data via an interface, the position data representing a measured position of a vehicle;
- reading in map data mapping road segments negotiable by the vehicle;
- reading in a plurality of particles that each represents an assumed position of the vehicle and a weighting assigned to the assumed position;
- determining a deviation between the plurality of particles and the measured position represented by the position data, using the map data;
- determining a plausible road segment of the road segments of the map data based on the deviation, for which it is assumed that the vehicle is situated thereon;
- comparing an instantaneous driving direction of the vehicle with a driving direction assigned to the determined road segment in the map data;
- and
- determining that the vehicle is driving in a wrong direction based on the comparing.

- compare an instantaneous driving direction of the vehicle with a driving direction assigned to the determined road segment in the map data;
- and
- determine that the vehicle is driving in a wrong direction based on the comparing.
