Abstract

A method for controlling a parking mode for a vehicle includes detecting an activation action of a user of the vehicle, determining a movement status of the vehicle, and activating a parking mode for the vehicle by closing a parking brake of a brake device of the vehicle and by engaging a gearshift lock of a transmission of the vehicle.

First claim

What is claimed is:

1. A method for controlling a parking mode for a vehicle, the method comprising:
detecting a single activation action of a user of the vehicle;
determining a movement status of the vehicle; and
triggering, in response to the detecting the single activation action of the user, two separate parking mode activation processes, wherein the two separate parking mode activation processes include (i) closing a parking brake of a brake device of the vehicle and (ii) engaging a gearshift lock of a transmission of the vehicle, and
carrying out the two separate parking mode activation processes so as to activate a parking mode.

2. The method as claimed in claim 1 , wherein when the parking mode is activated, the movement status is taken into account.

3. The method as claimed in claim 2 , wherein the parking mode is activated only if the vehicle is in a stationary state.

4. The method as claimed in claim 1 , wherein the single activation action of the user of the vehicle comprises at least one of the following actions:
actuating of an activation element,
execution of an activation gesture which can be detected with a sensor,
utterance of an activation command, or
exiting of the user from the vehicle.

5. The method as claimed in claim 1 , wherein the two separate parking mode activation processes are activated automatically when the vehicle comes to a standstill by detecting a stopping action of the user.

6. The method as claimed in claim 1 , further comprising:
before triggering the two separate parking mode activation processes, determining a location of the user relative to a passenger compartment of the vehicle.

7. The method as claimed in claim 1 , wherein the two separate parking mode activation processes are carried out simultaneously.

8. The method as claimed in claim 1 , further comprising deactivating the parking mode in response to detecting a release action of the user of the vehicle, wherein the release action comprises at least one of the following actions:
actuation of an activation element,
execution of a release gesture which can be detected with a sensor,
utterance of a release command,
entry of the user into the vehicle,
starting of the vehicle, or
engagement of a driving position or of a neutral position of the transmission.

9. The method as claimed in claim 1 , wherein when the movement status of the vehicle is determined to be a moving state with a speed of movement above a predefined threshold value, an emergency braking mode of the vehicle is activated.

10. The method as claimed in claim 9 , wherein carrying out the two separate parking mode activation processes so as to activate the parking mode when the emergency braking mode is activated comprises closing the parking brake of the vehicle in a quantitatively continuous fashion until the speed of movement falls below the predefined threshold value and subsequently engaging the gearshift lock of the transmission.

11. The method as claimed in claim 1 , wherein when a special action of the user of the vehicle is detected, at least one of the following actions is carried out:
closing of an open parking brake when the gearshift lock is engaged,
closing of an open parking brake when the transmission is in a driving position,
closing of an open parking brake when the transmission is in a neutral position, or
opening of a closed parking brake.

12. The method as claimed in claim 1 , wherein the parking brake of the brake device of the vehicle is located at a wheel of the vehicle.

13. The method as claimed in claim 1 , wherein the single activation action of the user of the vehicle is composed of a multiplicity of individual action components, and
wherein the multiplicity of individual action components include mechanical actuation of a pushbutton key and a corresponding utterance of an activation command.

14. The method as claimed in claim 1 , wherein carrying out the two separate parking mode activation processes so as to activate the parking mode comprises engaging the gearshift lock of the transmission of the vehicle before closing the parking brake of the vehicle to permit a certain degree of transmission play thereby allowing corresponding mechanical elements to be oriented with respect to one another.

15. A control device, comprising:
a first sensor configured to detect single activation action of a user of a vehicle,
a second sensor configured to determine a movement status of the vehicle, and
an activator configured to trigger, in response to the detecting the single activation action of the user, two separate parking mode activation processes, wherein the two separate parking mode activation processes include (i) closing a parking brake of a brake device of the vehicle and (ii) engaging a gearshift lock of a transmission of the vehicle.
