Abstract

A method for assisting a maneuvering process of a motor vehicle, and a parking assistance device are provided. In a method for assisting a maneuvering process of a motor vehicle, wherein longitudinal and lateral control of the movement of the motor vehicle is carried out on the basis of predefined setpoint values of the direction of travel, speed or steering angle in order to automatically carry out the maneuvering process, at least some of these setpoint values and the chronological sequence in which the setpoint values are predefined during the maneuvering process are stored.

Claims

1. A method comprising:

during an assisted parking maneuver (APM) in which a stored plurality of set point values define a portion of a maneuvering trajectory followed by a vehicle during the APM, and in response to occurrence of a stuck condition, processing by a controller the plurality in reverse order to exit the stuck condition by returning the vehicle to a position on the maneuvering trajectory encountered prior to the stuck condition.

2. The method according to claim 1 further comprising altering at least one of the set point values based on a fault associated with the maneuvering trajectory.

3. The method according to claim 1, wherein the set point values are stored in a chronological sequence.

4. The method according to claim 1, wherein each of the set point values specifies a predefined direction of travel.

5. The method according to claim 1, wherein each of the set point values specifies a predefined speed.

6. The method according to claim 1, wherein each of the set point values specifies a predefined steering angle.

7. A method for assisting a maneuvering process of a motor vehicle, comprising:

by a controller, carrying out longitudinal and lateral control of movement of the motor vehicle based on predefined setpoint values of direction of travel, speed or steering angle in order to automatically carry out the maneuvering process, wherein at least some of the setpoint values and a chronological sequence in which the setpoint values are predefined during the maneuvering process are stored chronologically.

8. The method as claimed in claim 7, wherein the storing is carried out in such a way that exiting from a vehicle position which is brought about during the maneuvering process is made possible based on the stored setpoint values.

9. The method as claimed in claim 8, wherein in order to exit from a vehicle position which is brought about during the maneuvering process, the stored setpoint values are predefined in a sequence which is opposed to the stored chronological sequence.

10. The method as claimed in claim 8, wherein the exiting from a vehicle position which is brought about during the maneuvering process is carried out by predefining the stored setpoint values in a sequence which is opposed to the stored chronological sequence, in reaction to a driver input.

11. The method as claimed in claim 7, wherein adaptation of setpoint values predefined in a later maneuvering process is performed based on the stored setpoint values.

12. The method as claimed in claim 11, wherein the adaptation is carried out if a fault which is induced during a maneuvering process with respect to the vehicle position which is brought about by the longitudinal and lateral control is above a predefined threshold value.

13. The method as claimed in claim 11, wherein the adaptation is carried out by taking into account at least one parameter which characterizes a state of the vehicle.

14. A parking assistance system comprising:

a controller programmed to, during an assisted parking maneuver (APM) in which a stored plurality of set point values define a portion of a maneuvering trajectory followed by a vehicle during the APM, and in response to occurrence of a stuck condition, process the plurality in reverse order to exit the stuck condition by returning the vehicle to a position on the maneuvering trajectory encountered prior to the stuck condition.

15. The system according to claim 14, wherein the controller is further programmed to alter at least one of the set point values based on a fault associated with the maneuvering trajectory.

16. The system according to claim 14, wherein the set point values are stored in a chronological sequence.

17. The system according to claim 14, wherein each of the set point values specifies a predefined direction of travel.

18. The system according to claim 14, wherein each of the set point values specifies a predefined speed.

19. The system according to claim 14, wherein each of the set point values specifies a predefined steering angle.
