Abstract

A method and a system for controlling a driving function of a vehicle, whereby in a first operating state, the driving function is controlled by a vehicle guidance system, and in a second operating state, the driving function is controlled by a command of a driver, a transition from the first operating state to the second operating state being accomplished with the aid of an orderly handover through a preset handover procedure when it is recognized that a predetermined first condition is fulfilled, or with the aid of a handover in a fallback solution when it is recognized that a predetermined second condition is fulfilled.

Claims

1-15. -15. (canceled)

16. A method for controlling a driving function of a vehicle, comprising:

in a first operating state, controlling the driving function by a vehicle guidance system; and

in a second operating state, controlling the driving function by a command of a driver;

wherein a transition from the first operating state to the second operating state being accomplished with the aid of an orderly handover through a preset handover procedure when it is recognized that a predetermined first condition is fulfilled, and with the aid of a handover in a fallback solution when it is recognized that a predetermined second condition is fulfilled.

17. The method as recited in claim 16, wherein a transition from the second operating state to the first operating state ensues when an input for a change from the second operating state to the first operating state takes place and a further condition is satisfied.

18. The method as recited in claim 16, wherein the first condition is satisfied when the vehicle is in a predetermined first operating range, and when the vehicle guidance system is in a predetermined first system state.

19. The method as recited in claim 16, wherein the second condition is satisfied when the vehicle is in a predetermined second operating range, and when the vehicle guidance system is in a predetermined second system state.

20. The method as recited in claim 19, wherein at least one of the first, the second, and a third operating range is a function of at least one defined limit, the at least one predefined limit including at least one of:

a specified road section, a national border, a predetermined speed range, a predetermined speed differential with respect to other vehicles, a predetermined traffic situation, a trajectory of the vehicle, a predetermined weather condition, and a predetermined road condition.

21. The method as recited in claim 19, wherein at least one of a first, a second, and a third system state, is a function of a failure of at least one of:

a sensor system, an actuator system, at least one functional part of the vehicle guidance system, and an overload of the vehicle guidance system.

22. The method as recited in claim 16, wherein prior to the handover procedure in the case of the orderly handover, a takeover request is made by a vehicle guidance system to the driver, and the driver indicating a take-back of driving responsibility to the vehicle guidance system by an input.

23. The method as recited in claim 16, wherein prior to a complete transfer of driving responsibility to the driver, the handover procedure checks for a predefined period of time, whether a predetermined driving behavior of the driver is present, and if the predetermined driving behavior is recognized, the driving responsibility is handed over to the driver, and if the predetermined driving behavior of the driver is not recognized, the driving responsibility of the driver is at least partially restricted.

24. The method as recited in claim 23, wherein in the event the predetermined driving behavior of the driver is not recognized, a command by the driver is at least partially ignored, and the vehicle is controlled at least in part by the vehicle guidance system.

25. The method as recited in claim 16, wherein in response to the presence of a third condition, a driver command, in the form of an intuitive intervention, replaces a control by the vehicle guidance system and is used to control the vehicle.

26. The method as recited in claim 25, wherein the third condition is an overload of the vehicle guidance system.

27. The method as recited in claim 25, wherein the third condition includes at least one of a third operating state of the vehicle and a third system state of the vehicle guidance system.

28. A method for controlling a driving function of a vehicle, comprising:

in a first operating state, controlling the driving function by a vehicle guidance system;

in a second operating state, controlling the driving function by a command of a driver; and

in response to the presence of a predetermined third system state of the vehicle guidance system, a driver command, in the form of an intuitive intervention, replaces a control by the vehicle guidance system and is used to control the vehicle.

29. The method as recited in claim 28, wherein the predetermined third system state is the vehicle guidance system being overloaded.

30. The method as recited in claim 28, wherein for a duration of an intuitive intervention by a driver, a driving responsibility remains with the vehicle guidance system, and only after a predetermined duration of the intuitive intervention by the driver, after the intuitive intervention has ended and in response to a further existing overload of the vehicle guidance system, is a request made by the vehicle guidance system to the driver to take over the driving responsibility.

31. The method as recited in claim 28, wherein the vehicle guidance system indicates the status in which it finds itself to the driver.

32. A system for controlling a driving function of a vehicle, the system designed to:

in a first operating state, control the driving function by a vehicle guidance system; and

in a second operating state, control the driving function by a command of a driver;

wherein a transition from the first operating state to the second operating state being accomplished with the aid of an orderly handover through a preset handover procedure when it is recognized that a predetermined first condition is fulfilled, and with the aid of a handover in a fallback solution when it is recognized that a predetermined second condition is fulfilled.
