Abstract

In a method for at least partly automated driving in a vehicle, termination of the automated driving function and at least partial transfer of vehicle control to the driver is carried out only after expiration of a takeover time span that is ascertained from the actuation by the driver of a device communicating with the vehicle. The device can be a mobile device.

Claims

1-12. -12. (canceled)

13. A method for at least partly automated driving in a vehicle, in which a driving system carries out one or more driving functions in automated fashion, the method comprising:

prompting a driver by the driving system;

after the prompting, ascertaining a takeover time span based on an actuation of a device communicating with the vehicle by the driver; and

only after expiration of the takeover time, terminating the automated drive function.

14. The method as recited in claim 13, wherein the device is a mobile device that connects to the vehicle in order to establish communication.

15. The method as recited in claim 13, wherein for the case in which a minimum operating time span, during which the vehicle is still driving in partly, highly, or fully automated fashion, is shorter than the takeover time span, a warning signal is generated.

16. The method as recited in claim 15, wherein at least on of:

(i) the warning signal is displayed to the driver, and (ii) the warning signal results in a limitation of the permissible actuation of the device.

17. The method as recited in claim 15, wherein the minimum operating time span is calculated on the basis of at least one of (i) sensorially ascertained vehicle state variables, and (ii) environmental information.

18. The method as recited in claim 13, wherein for ascertaining the takeover time span, different actuations of the device by the driver are assigned different actuation weighting factors.

19. The method as recited in claim 18, wherein the actuation weighting factors are stored on the device and are reused in the context of a future partly, highly, or fully automated journey.

20. A closed- or open-loop control device for at least partly automated driving in a vehicle, in which a driving system carries out one or more driving functions in automated fashion, the control device designed to:

prompt a driver by the driving system;

after the prompt, ascertain a takeover time span based on an actuation of a device communicating with the vehicle by the driver; and

only after expiration of the takeover time, terminate the automated drive function.

21. A driving system in a vehicle for partly, highly, or fully automated driving, in which a driving system carries out one or more driving functions in automated fashion, the driving system having a closed- or open-loop control device, the control device designed to:

prompt a driver by the driving system;

after the prompt, ascertain a takeover time span based on an actuation of a device communicating with the vehicle by the driver; and

only after expiration of the takeover time, terminate the automated drive function.

22. A vehicle for partly, highly, or fully automated driving, in which a driving system carries out one or more driving functions in automated fashion, having a driving system with a closed- or open-loop control device, the control device designed to:

prompt a driver by the driving system;

after the prompt, ascertain a takeover time span based on an actuation of a device communicating with the vehicle by the driver; and

only after expiration of the takeover time, terminate the automated drive function.

23. The vehicle as recited in claim 22, further comprising:

a communication interface for connecting a mobile device.

24. The vehicle as recited in claim 23, wherein the mobile device is one of a smartphone, a mobile telephone, or a tablet.
