Abstract

The invention relates to a method for carrying out an at least semiautonomous process for parking a motor vehicle (1) on a road (10) by means of a parking assistance system of the motor vehicle (1), the parking assistance system (2) sensing a dimension of a parking space potentially suitable for the parking process, comparing the sensed dimension with a minimum dimension (19) dependent on a vehicle dimension (20), and carrying out the parking process assuming that the sensed dimension is at least equal to the minimum dimension (19), the parking assistance system (2) sensing a gradient (α) of the road (10) and setting the minimum dimension (19) on the basis of the gradient (α) during operation of the parking assistance system (2).

Claims

1. A method for carrying out an at least semiautonomous process for parking a motor vehicle on a road by a parking assistance system of the motor vehicle, the parking assistance system being configured to carry out the method comprising:

sensing at least one dimension of a parking space potentially suitable for the parking process;

comparing the sensed at least one dimension with a minimum dimension dependent on a vehicle dimension;

carrying out the parking process when the sensed at least one dimension is at least equal to the minimum dimension; and

,

sensing a gradient of the road and setting the minimum dimension on the basis of the gradient during operation of the parking assistance system.

2. The method according to claim 1, wherein the parking process is carried out into a parallel parking space, the main direction of extent of which runs parallel to the road, the vehicle dimension being a length of the motor vehicle measured in the longitudinal direction of the vehicle.

3. The method according to claim 1, wherein for the parking process, a check is carried out in order to determine whether the sensed gradient of the road exceeds a predefined threshold value in terms of absolute value, and a constant minimum dimension is set for a gradient below the threshold value.

4. The method according to claim 1, wherein the minimum dimension is set according to a continuous characteristic curve which indicates the dependence of the minimum dimension on the sensed gradient.

5. The method according to claim 1, wherein the minimum dimension is set gradually on the basis of the sensed gradient, with the result that a value of the minimum dimension is respectively assigned to at least two value ranges of the gradient.

6. The method according to claim 1, wherein a sign of the gradient is determined by the parking assistance system and the minimum dimension is also set taking the sign into account.

7. The method according to claim 1, wherein the practice of carrying out the parking process by the parking assistance system at least further comprises determining a relative position of the motor vehicle with respect to the parking space and determining a parking course for parking the motor vehicle in the parking space.

8. The method according to claim 1, wherein the dimension of the parking space is sensed by a distance sensor of the parking assistance system while the motor vehicle moves past the parking space.

9. A parking assistance system for carrying out an at least semiautonomous process for parking a motor vehicle, the parking assistance system being configured to:

sense a dimension of a parking space potentially suitable for the parking process;

compare the sensed dimension with a minimum dimension dependent on a vehicle dimension;

carry out the parking process assuming that the sensed dimension is at least equal to the minimum dimension, and

sense a gradient of a road on which the motor vehicle is situated and to set the minimum dimension on the basis of the gradient during operation.

10. A motor vehicle having a parking assistance system according to claim 9.
