Abstract: A method for predicting a driving maneuver in a driver assistance system of a motor vehicle. Based on dynamic data of the vehicle detected with the aid of sensors, a history of a driving maneuver, which is not yet completed, is recorded and, based on the history, a future course of the driving maneuver is predicted. Multiple hypotheses for potentially occurring driving maneuvers are represented by respective associated sets of parameters. A theoretical history of the driving maneuver is calculated based on the parameters for each hypothesis. The recorded history is compared to at least one of the theoretical histories. Based on a similarity degree, the hypothesis which describes the presently occurring driving maneuver with the highest probability is determined and output as the prediction result.
