Method and apparatus for determining a plausible lane for guiding a vehicle and an automobile
First Claim
1. A method for determining a physical lane on a roadway for a vehicle having at least three independent sensors, comprising the steps of:
- a) obtaining data for a first area surrounding the vehicle with at least one first sensor;
b) determining a first representation of the lane based on the data for the first area surrounding the vehicle;
c) obtaining data for at least two additional areas surrounding the vehicle with at least two additional sensors;
d) determining at least two additional representations of the lane based on the data for the at least two additional areas surrounding the vehicle;
e) comparing the first representation of the lane with the at least two additional representations of the lane to determine whether at least two representations of the first representation of the lane and the at least two additional representations of the lane are identical, andf) determining the physical lane from the at least two representations of the lane that are identical and omitting from consideration a representation of a lane that is not identical with the at least two identical representations of the lane.

Abstract
A method for determining a lane on a roadway for a vehicle having at least two independent sensors includes the steps of obtaining with a first sensor data for a first area surrounding the vehicle, obtaining with at least two additional sensors data for at least two additional areas surrounding the vehicle, determining a first lane based on the data for the first area, determining at least two additional lanes based on the data for the at least two additional areas, and determining a resulting lane from the first and the at least two additional lanes, wherein when two of the least three lanes are identical and a third of the at least three lanes is not identical with the two identical lanes, the third lane is not taken into account when determining the resulting lane.
