Method for deactivating an automated driving function of a vehicle and driver assistance system for implementing the method
A method for deactivating an automated driving function of a vehicle, in particular a highly automated or autonomous driving function, is provided. The driving function is deactivated when a driver of the vehicle carries out a steering intervention or pedal intervention with a strength exceeding a predeterminable deactivation threshold. The deactivation threshold is predetermined depending on an operation length of the driving function and/or depending on a responsiveness of the driver. In particular, the deactivation threshold is predetermined in such a manner that it is higher directly after an activation of the driving function than some time afterwards and/or it is higher with a low responsiveness of the driver than with a high responsiveness of the driver.
1. A method, comprising:
activating an automated driving function of a vehicle;
determining whether a driver intervention occurs; and
deactivating the automated driving function responsive to the driver intervention exceeding a predetermined deactivation threshold, wherein the deactivation threshold is predetermined depending on an operation length of the automated driving function and on a responsiveness of the driver.
2. The method of claim 1 , wherein the deactivation threshold is predetermined in such a manner that the deactivation threshold is higher directly after an activation of the driving function than a period of time after activation of the driving function.
3. The method of claim 1 , wherein the deactivation threshold is predetermined in such a manner that the deactivation threshold continuously decreases to a predefined pre-set threshold value as time increases since the activation of the driving function.
4. The method of claim 1 , wherein the deactivation threshold is predetermined in such a manner that, during a predetermined time window from the activation of the driving function, the deactivation threshold is at least equal to a value corresponding to a driver intervention occurring when the driving function is activated.
5. The method of claim 1 , wherein the driver intervention is a pedal intervention in a pedal of the vehicle or a steering intervention in a steering wheel of the vehicle.
6. The method of claim 1 , wherein the method is performed during a highly automated or autonomous driving operation.
7. The method of claim 1 , wherein the deactivation threshold is predetermined in such a manner that the deactivation threshold is higher with a low responsiveness of the driver than with a high responsiveness of the driver.
8. The method of claim 1 , further comprising:
determining the responsiveness of the driver based on drive-extrinsic operating actions.
9. The method of claim 1 , wherein the predetermined activation threshold increases to a threshold value so long as a driver of the vehicle is inattentive.
10. The method of claim 9 , wherein the predetermined activation threshold decreases from the threshold value when the driver is responsive again.
11. A method, comprising: activating an automated driving function of a vehicle; determining whether a driver intervention occurs; and deactivating the automated driving function responsive to the driver intervention exceeding a predetermined deactivation threshold, wherein the deactivation threshold is predetermined depending on an operation length of the automated driving function and on a responsiveness of the driver, wherein the deactivation threshold is predetermined in such a manner that the deactivation threshold is higher with a low responsiveness of the driver than with a high responsiveness of the driver.
12. The method of claim 11 , further comprising:
determining the responsiveness of the driver based on drive-extrinsic operating actions.
13. The method of claim 11 , wherein the predetermined activation threshold increases to a threshold value so long as a driver of the vehicle is inattentive.
14. The method of claim 13 , wherein the predetermined activation threshold decreases from the threshold value when the driver is responsive again.
15. A driver assistance system for a highly automated or autonomous driving operation of a vehicle, the driver assistance system being configured to:
activate an automated driving function of a vehicle;
determine whether a driver intervention occurs; and
deactivate the automated driving function responsive to the driver intervention exceeding a predetermined deactivation threshold, wherein the deactivation threshold is predetermined depending on an operation length of the automated driving function and on a responsiveness of the driver.
16. The driver assistance system of claim 15 , wherein the deactivation threshold is predetermined in such a manner that the deactivation threshold is higher with a low responsiveness of the driver than with a high responsiveness of the driver.
17. The driver assistance system of claim 15 , wherein the driver assistance system is further configured to:
determine the responsiveness of the driver based on drive-extrinsic operating actions.
18. The driver assistance system of claim 15 , wherein the predetermined activation threshold increases to a threshold value so long as a driver of the vehicle is inattentive.
19. The driver assistance system of claim 18 , wherein the predetermined activation threshold decreases from the threshold value when the driver is responsive again.
