Abstract

A driver assistance system and method for a motor vehicle includes a detector that is designed to detect at least one object in the area surrounding the vehicle. A vector field generator is configured to create an environmental potential field for the at least one object detected in the area surrounding the vehicle and to calculate a vector field from the created environmental potential field. A control device is configured to define control commands for the vehicle on the basis of the calculated vector field.

Claims

1-15. -15. (canceled)

16. A driver assistance system for a motor vehicle comprising:

a detector configured to detect at least one object in the area surrounding the vehicle;

a vector field generator configured to create an environmental potential field for the at least one object detected in the area surrounding the vehicle and to calculate a vector field from the created environmental potential field; and

a control device configured to define control commands for the vehicle on the basis of the calculated vector field, which commands will guide the vehicle past the at least one detected object.

17. The driver assistance system according to claim 16, wherein the vector field generator creates a plurality of environmental potential fields, superimposes the plurality of created environmental potential fields on each other to form a total potential field, and calculates the vector field from the total potential field.

18. The driver assistance system according to claim 16, wherein the detector comprises a plurality of sensors which detect an object in the area surrounding the vehicle.

19. The driver assistance system according claim 16, wherein the detector comprises at least one of a radar sensor, an ultrasonic sensor, a camera, and a LIDAR.

24. A vehicle comprising:

a driver assistance system including;

a detector configured to detect at least one object in the area surrounding the vehicle;

a vector field generator configured to create an environmental potential field for the at least one object detected in the area surrounding the vehicle and to calculate a vector field from the created environmental potential field; and

a control device configured to define control commands for the vehicle on the basis of the calculated vector field, which commands will guide the vehicle past the at least one detected object.

25. A method for operating a driver assistance system for a vehicle comprising:

detecting at least one object in the area surrounding the vehicle;

creating an environmental potential field for the at least one detected object;

calculating a vector field from the created environmental potential field; and

defining a control command for the vehicle that guides the vehicle past the at least one detected object using the calculated vector field.

26. The method according to claim 25, further comprising superimposing a plurality of environmental potential fields on each other to produce a total potential field, wherein calculating the vector field comprises calculating the vector field from the total potential field.

27. The method according to either of claims 25, further comprising receiving information about at least one object in the area surrounding the vehicle.
