Parking assistance apparatus for aiding a driver of a motor vehicle with a parking process

1. A parking assistance apparatus for aiding a driver of a motor vehicle with a parking process, comprising:

a sensor, of the motor vehicle, configured to record environment data of the motor vehicle during a parking process in an environment;

a memory device, of the motor vehicle, configured to temporarily store a parking trajectory performed by the driver during the parking process and the recorded environment data; and

a processor, of the motor vehicle, configured to:

check the driver-performed parking trajectory for a more efficient parking trajectory,

analyze the driver-performed parking trajectory with respect to the recorded environment and detect a driving error in the driver-performed parking trajectory with respect to the recorded environment,

determine a trained parking trajectory with respect to the recorded environment by adjusting the driver-performed parking trajectory based on the driving error,

recognize an area that should be avoided,

produce a modified trained parking trajectory based on instructions from the driver, via a user interface, rejecting at least a portion of the trained parking trajectory that includes the area that should be avoided, and

autonomously control the motor vehicle based on the modified trained parking trajectory.

2. The parking assistance apparatus according to claim 1 , wherein the processor is configured to determine a more efficient parking trajectory when a parking trajectory that is shorter in terms of time and/or distance in comparison with the driver-performed parking trajectory is performable.

3. The parking assistance apparatus according to claim 1 , wherein in order to determine a more efficient parking trajectory, the processor is further configured to compare the driver-performed parking trajectory with a space in which it is possible to freely maneuver, said space having been evaluated from the recorded environment data.

4. The parking assistance apparatus according to claim 3 , wherein for the comparison, the processor is further configured to generate a virtual map from the recorded environment data and odometry data of the motor vehicle.

5. The parking assistance apparatus according to claim 4 , wherein the virtual map comprises at least the following information:

objects which, for the motor vehicle, restrict a space in which it is possible to freely maneuver;

the trained parking trajectory;

the relative position of the objects to one another and to the current position of the motor vehicle.

6. The parking assistance apparatus according to claim 1 , wherein the processor is further configured to offer the driver the parking trajectory determined to be more efficient as a parking option before it is established as a trained parking trajectory.

7. The parking assistance apparatus according to claim 6 , wherein the parking assistance apparatus comprises or is connectable to the user interface, the user interface allowing the driver to select or reject the entirety or merely one or more portions of the parking trajectory determined to be more efficient.

8. A motor vehicle comprising a parking assistance apparatus according to claim 1 .

9. A method for aiding a driver of a motor vehicle with a parking process, comprising:

recording, by a sensor of the motor vehicle, environment data of the motor vehicle at least during a parking process in an environment;

temporarily storing, by a memory device of the motor vehicle, the parking trajectory performed by the driver during the parking process and the recorded environment data;

checking, by a processor of the motor vehicle, the driver-performed parking trajectory for a more efficient parking trajectory;

analyzing, by the processor of the motor vehicle, the driver-performed parking trajectory with respect to the recorded environment and detecting a driving error in the driver-performed parking trajectory with respect to the recorded environment;

determining, by the processor of the motor vehicle, a trained parking trajectory with respect to the recorded environment by adjusting the driver-performed parking trajectory based on the driving error;

recognizing, by the processor of the motor vehicle, an area that should be avoided;

producing, by the processor of the motor vehicle, a modified trained parking trajectory based on instructions from the driver, via a user interface, rejecting at least a portion of the trained parking trajectory that includes the area that should be avoided; and

autonomously controlling the motor vehicle based on the modified trained parking trajectory.

10. A computer program element, which, when executed on a processor of a parking assistance apparatus, instructs the parking assistance apparatus to carry out the method according to claim 9 .

11. The parking assistance apparatus according to claim 2 , wherein in order to determine a more efficient parking trajectory, the processor is further configured to compare the driver-performed parking trajectory with a space in which it is possible to freely maneuver, said space having been evaluated from the recorded environment data.

12. The parking assistance apparatus according to claim 1 , wherein the driving error is a corrective maneuver of the motor vehicle that is performed by the driver during the parking process.

13. The method according to claim 9 , wherein the driving error is corrective maneuver of the motor vehicle that is performed by the driver during the parking process.

14. The parking assistance apparatus according to claim 1 , wherein the area that should be avoided is a private property.

15. The method according to claim 9 , wherein the area that should be avoided is a private property.
