Abstract

A method and device for selecting a parking assistance function from a predefined group of parking assistance functions of a parking steering assistant by an input element of the parking steering assistant of a motor vehicle. The parking assistance functions are arranged in two groups, wherein the first group includes the functions which relate to parking of the vehicle and the second group includes functions which relate to exiting a parking space by the vehicle. A selection is made between the two function groups as a function of the ignition switch state and a distance traveled by the vehicle, as a result of which the method differentiates automatically between parking functions and parking space exiting functions.

Claims

1. A method for selecting a parking assistance function from amongst a predefined plurality of parking assistance functions provided by a parking steering assistant of a motor vehicle the method comprising:

displaying the parking assistance functions in a plurality of groups, with a first group comprising functions that relate to the vehicle driving into a parking space and a second group comprising functions that relate to the vehicle driving out of a parking space; and

receiving user input of the parking assistance function via one or more input elements of the parking steering assistant,

wherein the motor vehicle has a sensor system for determining an area surrounding the motor vehicle and a selection is made between the first and second group of functions based on an ignition switch state of the motor vehicle and the distance covered by the motor vehicle.

2. The method of claim 1, wherein:

the first group of functions is selected if the ignition switch is in an “

on”

state and the distance covered is greater than a predefined threshold after the ignition switch state becomes “

on”

, and

the second group of functions is selected when the ignition switch is in the “

on”

state and a distance covered is less than or equal to the predefined threshold after the ignition switch state becomes “

on”

.

3. The method of claim 1, wherein, after one of the groups of functions has been selected, the parking assistance functions of the selected group can be selected by a user in a predefined order using the input element.

4. The method of claim 1, a direction of driving into a parking space or driving out of a parking space is established by a driving direction indicator coupled to the parking steering assistant.

5. The method of claim 1, further comprising determining and classifying parking spaces, in the area surrounding the motor vehicle into parallel parking spaces and bay parking spaces, and selecting a parking assistance function from amongst the selected group of functions of the parking assistance functions based on the classified parking space.

6. The method of claim 5, wherein a direction of driving into a parking space or driving out of a parking space is determined based on the classified parking space and/or is established by the driving direction indicator.

7. The method of claim 1, wherein the first group of functions comprises functions of driving forward into a bay parking space, reversing into a bay parking space and reversing into a parallel parking space, and the second group of functions comprises the functions of driving out of a parallel parking space and driving out of a bay parking space.

8. The method of claim 1, wherein a current driver assistance function and subsequently the execution of a selected driver assistance function are symbolically displayed on a display unit.

13. The method of claim 2, wherein, after one of the groups of functions has been selected, the parking assistance functions of the selected group can be selected by a user in a predefined order using the input element.

14. The method of claim 2, further comprising determining and classifying parking spaces in the area surrounding the motor vehicle into parallel parking spaces and bay parking spaces, and selecting a parking assistance function from amongst the selected group of functions of the parking assistance functions based on the classified parking space.

15. The method of claim 14, wherein a direction of driving into a parking space or driving out of a parking space is determined based on the classified parking space and/or is established by the driving direction indicator.

16. The method of claim 2, wherein the first group of functions comprises functions of driving forward into a bay parking space, reversing into a bay parking space and reversing into a parallel parking space, and the second group of functions comprises the functions of driving out of a parallel parking space and driving out of a bay parking space.

17. The method of claim 2, wherein a current driver assistance function and subsequently the execution of a selected driver assistance function are symbolically displayed on a display unit.

9. A parking steering assistant of a motor vehicle for selecting amongst and performing a predefined plurality of parking assistance functions provided by the parking steering assistant of a motor vehicle, the system comprising:

a surrounding area sensor system that determines an area surrounding the motor vehicle;

an evaluation unit determines parking spaces in the area surrounding the motor vehicle;

a control unit that controls the parking assistance functions with respect to driving into a parking space and driving out of a parking space;

at least one input element that activates the parking steering assistant and selects one of its functions and

a selection device which makes a selection between a plurality of groups of functions of the parking steering assistant as a function of an ignition switch state and a distance covered by the motor vehicle,

wherein a first group of functions relates to functions for driving into a parking space and a second group of functions relates to functions for driving out of a parking space.

10. The parking steering assistant of claim 9, wherein the selection device selects the first group of functions when the ignition switch is in an “

on”

state and a distance covered is greater than a predefined threshold after the ignition switch state becomes “

on”

, and wherein the second group of functions is selected when the ignition switch is in the “

on”

state and a distance covered is less than or equal to the predefined threshold after the ignition switch state becomes “

on”

.

11. The parking steering assistant of claim 9, wherein the first group of functions comprises functions of driving forward into a bay parking space, reversing into a bay parking space and reversing into a parallel parking space, and the second group of functions comprises functions of driving out of a parallel parking space and driving out of a bay parking space.

12. The parking steering assistant of claim 9, wherein the evaluation unit determines and classifies the parking spaces in the area surrounding the motor vehicle and the selection unit selects a parking assistance function from amongst the selected group of functions based on the classified parking space.

18. The parking steering assistant of claim 10, wherein the first group of functions comprises functions of driving forward into a bay parking space, reversing into a bay parking space and reversing into a parallel parking space, and the second group of functions comprises functions of driving out of a parallel parking space and driving out of a bay parking space.

19. The parking steering assistant of claim 18, wherein the evaluation unit determines and classifies the parking spaces in the area surrounding the motor vehicle and the selection unit selects a parking assistance function from amongst the selected group of functions based on the classified parking space.

20. The parking steering assistant of claim 11, wherein the evaluation unit determines and classifies the parking spaces in the area surrounding the motor vehicle and the selection unit selects a parking assistance function from amongst the selected group of functions based on the classified parking space.
