Abstract

A method for operating a control system for dynamics control of a vehicle, in particular a motor vehicle, which includes: detecting an object with the aid of at least one surroundings detection device which detects a detection area in the vehicle surroundings, determining the probability of an interaction, between the vehicle and the object, to cause damage to the vehicle or its occupants, and changing the intensity of a control intervention by the vehicle dynamics control system as a function of the previously determined probability of an interaction between the vehicle and the object in at least one operating mode of the control system, the vehicle dynamics control system being a vehicle dynamics control system for preventing a lateral breakaway of the vehicle. Also described is a corresponding control unit and control system.

Claims

1-11. -11. (canceled)

12. A method for operating a control system for providing dynamic control of a vehicle, the method comprising:

detecting an object with the aid of at least one surroundings detection device which detects a detection area in the vehicle surroundings;

determining a probability of an interaction, which is between the vehicle and the object, to cause damage to the vehicle or an occupant; and

changing an intensity of a control intervention by the vehicle dynamics control system as a function of the previously determined probability of an interaction between the vehicle and the object in at least one operating mode of the control system, the vehicle dynamics control system being a vehicle dynamics control system for preventing a lateral breakaway of the vehicle.

13. The method of claim 12, wherein the change in the intensity of the control intervention by the vehicle dynamics control system includes automatically activating or deactivating this vehicle dynamics control system.

14. The method of claim 12, wherein the detection of the object includes an ascertainment of at least one of a position, a speed and an acceleration of the object relative to the vehicle.

15. The method of claim 12, wherein the surroundings detection device includes at least one of a visual and an acoustic sensor, which is a sensor of a radar system, a sensor of an infrared vision system, a camera of a video system and a sensor of an ultrasonic system.

16. The method of claim 12, wherein the surroundings detection device includes a surroundings detection device of a driver assistance system of the vehicle.

17. The method of claim 12, wherein the determination of the probability of an interaction between the vehicle and the object is a determination of the probability of an interaction between the vehicle and the object, and wherein the change in the intensity of the control intervention by the vehicle dynamics control system takes place as a function of a preselected probability threshold.

18. The method of claim 12, wherein the driver of the vehicle selects the at least one operating mode from multiple selectable operating modes.

19. A control unit for operating a control system for providing dynamic control of a vehicle, comprising:

a determining arrangement to determine a probability of an interaction, between the vehicle and an object detected in the vehicle surroundings, to cause damage to the vehicle or an occupant, wherein the object is detected with the aid of at least one surroundings detection device which detects a detection area in the vehicle surroundings; and

an intensity arrangement to change an intensity of a control intervention by the vehicle dynamics control system as a function of the probability of the interaction between the vehicle and the object in at least one operating mode of the control system, the vehicle dynamics control system being a vehicle dynamics control system for preventing a lateral breakaway of the vehicle.

20. A control system for providing dynamic control of a vehicle, comprising:

at least one surroundings detection device to detect a detection area in a vehicle surroundings for detecting an object;

a probability arrangement to determine a probability of an interaction, between the vehicle and the object, to cause damage to the vehicle or an occupant; and

an intensity arrangement to change the intensity of a control intervention by the vehicle dynamics control system as a function of the probability of the interaction between the vehicle and the object in at least one operating mode of the control system, the vehicle dynamics control system being a vehicle dynamics control system for preventing a lateral breakaway of the vehicle.

21. The system of claim 20, wherein the surroundings detection device includes at least one of a visual and an acoustic sensor, which includes at least one of a sensor of a radar system, a sensor of an infrared vision system, a camera of a video system and a sensor of an ultrasonic system.

22. The system of claim 20, further comprising:

a selection device to select an operating mode from multiple selectable operating modes.
