Abstract

In a method for safely parking a vehicle, it is checked whether an emergency situation is present, and the vehicle is driven by the driver assistance system to a road shoulder upon recognition of an emergency situation. In controlling the driving operation, information is requested from an external database and taken into account by the driver assistance system.

Claims

1-15. -15. (canceled)

16. A method for automatically parking a vehicle, comprising:

checking, using a monitoring of the vehicle, whether an emergency situation is present; and

automatically parking the vehicle, by a driver assistance system of the vehicle, upon recognition of an emergency situation;

wherein the driver assistance system requests information from an external database and takes into account the requested information in automatically parking the vehicle.

17. The method as recited in claim 16, wherein at least one of (i) data of a digital map regarding a road shoulder and (ii) information of the external database regarding the road shoulder is taken into account by the driver assistance system.

18. The method as recited in claim 17, wherein the driver assistance system is configured to selectively transfer the control of the driving function to the driver, and

(i) if the driver assistance system indicates to the driver an intended transfer of control of the driving function to the driver but the driver refuses to take control of the driving function, an emergency situation is recognized and the vehicle is automatically parked by the driver assistance system, and

(ii) if the driver assistance system indicates to the driver an intended transfer of control of the driving function to the driver and the driver indicates an intent to take control of the driving function, the automatic parking of the vehicle is interrupted by the driver assistance system.

19. The method as recited in claim 18, wherein at least one of a health state, tiredness, a state of distraction, and intoxication of the driver is checked to recognize an emergency situation.

20. The method as recited in claim 17, wherein a weight distribution of the driver is monitored and an emergency situation is recognized in the case of a predefined deviation of the weight distribution from a predefined reference distribution.

21. The method as recited in claim 17, wherein a selected technical function of the vehicle is checked and an emergency situation is recognized when the selected technical function does not have a predefined functionality.

22. The method as recited in claim 17, wherein the surroundings of the vehicle are detected by sensors and taken into account by the driver assistance system.

23. The method as recited in claim 17, wherein at least one of (i) a speed of a target vehicle ahead and (ii) a distance from the target vehicle is detected and taken into account by the driver assistance system during braking and changing lanes.

24. The method as recited in claim 17, wherein upon recognition of an emergency situation:

data about the road shoulder in the driving direction of the vehicle are analyzed for a possible stopping place for the vehicle within a defined distance from the vehicle;

a stopping place is selected based on the analysis; and

the driver assistance system automatically drives the vehicle to the stopping place and parks the vehicle at the selected stopping place.

25. The method as recited in claim 24, wherein upon recognition of an emergency situation, a transmission of additional data about the health of the driver to a rescue center is initiated by the vehicle with the aid of an external database.

26. The method as recited in claim 24, wherein upon recognition of an emergency situation, a transmission of technical data about the vehicle to a rescue center is activated.

27. The method as recited in claim 26, wherein the technical data are one of detected by sensors of the vehicle, read out from an internal database, or read out from an external database.

28. The method as recited in claim 19, wherein a message is output to the driver upon recognition of tiredness of the driver, and wherein one of the frequency of the output or the intensity of the output is a function of the degree of tiredness.

29. The method as recited in claim 17, wherein upon recognition of an emergency situation, the vehicle is one of (i) decelerated by the driver assistance system in the lane and stopped, or (ii) the vehicle is driven by the driver assistance system to a road shoulder and stopped.

30. A non-transitory computer-readable data storage medium storing a computer program having program codes which, when executed on a computer, performs a method for automatically parking a vehicle, the method comprising:

checking, using a monitoring of the vehicle, whether an emergency situation is present; and

automatically parking the vehicle, by a driver assistance system of the vehicle, upon recognition of an emergency situation;

wherein the driver assistance system requests information from an external database and takes into account the requested information in automatically parking the vehicle;

wherein at least one of (i) data of a digital map regarding a road shoulder and (ii) information of the external database regarding the road shoulder is taken into account by the driver assistance system; and

wherein upon recognition of an emergency situation;

data about the road shoulder in the driving direction of the vehicle are analyzed for a possible stopping place for the vehicle within a defined distance from the vehicle;

a stopping place is selected based on the analysis; and

the driver assistance system automatically drives the vehicle to the stopping place and parks the vehicle at the selected stopping place.
