Abstract

The invention concerns a method for unparking a motor vehicle (1) from a cross-parking space (8), with which the motor vehicle (1) is manoeuvred along an unparking trajectory (9) at least semi-autonomously from the cross-parking space (8) onto a road (10) bounding on the cross-parking space (8), wherein during said semi-autonomous manoeuvring of the motor vehicle (1) along the unparking trajectory (9), at least one reversing movement is carried out, an end position (E) is determined and the semi-autonomous manoeuvring of the motor vehicle (1) along the unparking trajectory (9) is ended at the end position (E), wherein the end position (E) is defined as at least a position such that in the event of further movement of the motor vehicle (1) from the end position (E) being carried out, manual control of the motor vehicle (1) in a driving direction (13) predetermined by the road (10) can be carried out by a driver of the vehicle without manoeuvring the motor vehicle (1) in a forward movement.

First claim

The invention claimed is:

1. A method for unparking a motor vehicle from a cross-parking space, comprising:
maneuvering the motor vehicle along an unparking trajectory at least semi-autonomously from the cross-parking space onto a road bounding on the cross-parking space;
during said semi-autonomous maneuvering of the motor vehicle along the unparking trajectory, carrying out at least one reversing movement;
determining an end position, wherein the semi-autonomous maneuvering of the motor vehicle along the unparking trajectory is ended at the end position, defined as at least a position such that in the event of further movement of the motor vehicle being carried out from the end position, manual control of the motor vehicle in a driving direction predetermined by the road is carried out by a driver of the vehicle without maneuvering the motor vehicle in a forward movement,
wherein the at least one reversing movement is carried out to move the motor vehicle from inside of the cross-parking space to the end position that is outside of the cross-parking space; and
after reaching the end position, engaging a forward gear, by a driver assistance system, so that the driver manually moves the motor vehicle forward, or issuing an instruction, by the driver assistance system to the driver of the motor vehicle, to engage the forward gear so that the driver manually moves the motor vehicle forward.

2. The method according to claim 1 , wherein at least one object is detected that bounds on the cross-parking space, and the end position is determined such that manual control in a forward movement past the at least one object without collisions is possible.

3. The method according to claim 2 , wherein a distance between the at least one object and the motor vehicle is continuously determined for detecting the at least one object during the maneuvering of the motor vehicle along the unparking trajectory.

4. The method according to claim 2 , wherein the end position is defined in such a way that manual control of the motor vehicle past the at least one object at a predefined safety distance in a forward movement is possible.

5. The method according to claim 1 , wherein the end position is determined under an assumption that a predefined steering angle, in particular a maximum steering angle, is set during manual control of the motor vehicle.

6. The method according to claim 5 , wherein the specified steering angle at the end position is set by means of the driver assistance system of the motor vehicle.

7. The method according to claim 1 , wherein a limiting element is detected that bounds on the road on a side opposite the cross-parking space, and the end position is determined depending on the detected limiting element.

8. The method according to claim 1 , wherein a forward movement and a further reversing movement are carried out for maneuvering the motor vehicle along the unparking trajectory.

9. The driver assistance system for the motor vehicle that is configured to carry out the method according to claim 1 .

10. The motor vehicle with the driver assistance system according to claim 9 .
