Method and system for assisting a driver of a vehicle in driving the vehicle, vehicle and computer program
First Claim
1. A method for assisting a driver of a vehicle in driving the vehicle, comprising the steps of:
- sensing an environment of the vehicle by sensors mounted on the vehicle;
determining parameters of the vehicle or objects in the environment of the vehicle on the basis of the sensor outputs, wherein a vehicle position is determined as one parameter of the determined parameters;
classifying an encountered traffic situation on the basis of the determined parameters by comparing the determined parameters with parameters of prototypical traffic situations that are stored in a database, wherein each of the prototypical traffic situations is related to one specific road and environment object configuration pattern;
extracting, from the database, risk information associated with the encountered traffic situation from the classification and the respective prototypical traffic situations,wherein the risk information associated with the prototypical traffic situation includes risk information on most frequent accident types for the respective prototypical traffic situation and the vehicle position;
calculating an expected risk for the encountered traffic situation on the basis of the extracted risk information; and
outputting driver information or actuating vehicle controls on the basis of the calculated expected risk in addition to the classified traffic situation,wherein the risk information comprises statistics related to a quantification of an expected risk for the respective prototypical traffic situation.

Abstract
An advanced driver assistant system and a method for assisting a driver of a vehicle in driving the vehicle. The system includes sensing means for sensing an environment of the vehicle, a storing unit for storing a database for storing prototypical situations associated with risk information, a processing unit and an output unit to output an assistance signal on the basis of which driver information can be output and/or vehicle operators can be actuated. The processing unit is configured to determine parameters of the vehicle and/or objects in the environment of the vehicle based upon the sensing means output, to classify a traffic situation on the basis of the determined parameters by comparing the determined parameters with parameters of the prototypical traffic situations, to extract risk information from the database and to calculate an expected risk for the encountered traffic situation on the basis of the extracted risk information.
