Abstract

An assistance System for a vehicle for providing an emergency stop assistance function that includes an execution device to execute the emergency stop assistance function using at least one of a plurality of activation stages; a detection device for automatic detection of driver inactivity, in order to activate the emergency stop assistance function using a first stage selection of the activation stages; a triggering device for monitoring an operating element of an electrical parking brake or a parking lock of a transmission of the vehicle, in order to activate the emergency assistance function using a second stage selection of the activation stages, which differs from the first stage selection, in the case of a manual activation of the operating element.

First claim

The invention claimed is:

1. An assistance system for a vehicle for providing an emergency stop assistance function, comprising:
an execution device configured to execute the emergency stop assistance function using a plurality of activation stages;
a detection device configured to automatically detect driver inactivity, and to activate the emergency stop assistance function using a first stage selection of the plurality of activation stages;
a triggering device for detecting a manually activated operating element for an electric parking brake or a parking lock in a transmission in the vehicle after the first stage selection is activated; and
activating the emergency stop assistance function using a second stage selection of the plurality of activation stages, based on the detected manually activated operating element, wherein the second stage selection is different from the first stage selection.

2. The assistance system according to claim 1 , further comprising an output initiation device configured to issue a warning in the first stage selection, wherein the execution device is further configured to execute a first activation stage in the first stage selection, and to skip the first activation stage in the second stage selection.

3. The assistance system according to claim 2 , further comprising an alarm initiation device for initiating at least one alerting action in a second activation stage, wherein the execution device is configured to execute the second activation stage in the first stage selection and in the second stage selection.

4. The assistance system according to claim 3 , wherein the alarm initiation device is configured to initiate the at least one alerting action by at least one of (i) activating a brake of the vehicle, and/or (ii) tensioning a seatbelt in the vehicle.

5. The assistance system according to claim 1 , further comprising a function initiation device for initiating a safety function of the vehicle comprising stopping the vehicle in a third activation stage, wherein the execution device is configured to execute the third activation stage in the first stage selection and in the second stage selection.

6. The assistance system according to claim 1 , wherein the triggering device is configured to ignore temporal intermittent activation of the operating element.

7. A method of operating an assistance system for a vehicle for providing an emergency stop assistance function, comprising:
configuring an execution device to execute the emergency stop assistance function using a plurality of activation stages;
automatically detecting driver inactivity via a detection device;
activating the emergency stop assistance function using a first stage selection of the plurality of activation stages;
detecting, via a trigger device, activation of a manually activated operating element for an electric parking brake or a parking lock in a transmission in the vehicle after the first stage selection is activated; and
activating the emergency stop assistance function using a second stage selection of the plurality of activation stages, based on the activation of the manually activated operating element, wherein the second stage selection is different from the first stage selection.

8. The method according to claim 7 , further comprising issuing a warning, via an output initiation device, in the first stage selection, and executing, via the execution device, a first activation stage in the first stage selection, and to skip the first activation stage in the second stage selection.

9. The method according to claim 8 , further comprising initiating, via an alarm initiation device, at least one alerting action in a second activation stage, and executing the second activation stage in the first stage selection and in the second stage selection.

10. The method according to claim 9 , further comprising initiating, via the alarm initiation device, the at least one alerting action by at least one of (i) activating a brake of the vehicle, and/or (ii) tensioning a seatbelt in the vehicle.

11. The method according to claim 7 , further comprising initiating, via a function initiation device, a safety function of the vehicle comprising stopping the vehicle in a third activation stage, and executing, via the execution device, the third activation stage in the first stage selection and in the second stage selection.

12. The method according to claim 7 , further comprising ignoring, via the triggering device, temporal intermittent activation of the operating element.

13. An assistance system for a vehicle for providing an emergency stop assistance function, comprising:
an execution device configured to execute the emergency stop assistance function using a plurality of activation stages;
a detection device configured to automatically detect driver inactivity with respect to at least one vehicle component, and to activate the emergency stop assistance function using a first stage selection comprising an automatic activation of the plurality of activation stages;
a triggering device for detecting activation of a manually activated operating element for an electric parking brake or a parking lock in a transmission in the vehicle to activate the emergency stop assistance function using a second stage selection, based on the activation of the manually activated operating element, after the first stage selection of the plurality of activation stages, wherein the second stage selection is configured to be executed after a predefined time period of detected driver inactivity has elapsed.

14. The assistance system according to claim 13 , further comprising an output initiation device configured to issue a warning in the first stage selection, wherein the execution device is further configured to execute a first activation stage in the first stage selection, and to skip the first activation stage in the second stage selection.

15. The assistance system according to claim 14 , further comprising an alarm initiation device for initiating at least one alerting action in a second activation stage, wherein the execution device is configured to execute the second activation stage in the first stage selection and in the second stage selection.

16. The assistance system according to claim 15 , wherein the alarm initiation device is configured to initiate the at least one alerting action by at least one of (i) activating a brake of the vehicle, and/or (ii) tensioning a seatbelt in the vehicle.

17. The assistance system according to claim 13 , further comprising a function initiation device for initiating a safety function of the vehicle comprising stopping the vehicle in a third activation stage, wherein the execution device is configured to execute the third activation stage in the first stage selection and in the second stage selection.

18. The assistance system according to claim 13 , wherein the triggering device is configured to ignore temporal intermittent activation of the operating element.
