Abstract
Estimating a lane change intention of a vehicle includes capturing a plurality of different lane change indicator signals, transforming the respective lane change indicator signals into respective associated individual probabilities of a lane change using respective assigned transformation functions, weighting these individual probabilities of a lane change, determining a weighted overall probability of a lane change as the average of the weighted individual probabilities of a lane change, and estimating the existence of a lane change intention depending on the overall probability of a lane change, and outputting an associated lane change estimation signal.
