Abstract

In a method for assisting a driver of a motor vehicle during a driving maneuver, the surroundings of the motor vehicle are initially detected, at least one suitable trajectory for carrying out the driving maneuver is computed based on the detected surroundings, and the motor vehicle is automatically steered in order to carry out the driving maneuver. If there is a malfunction, the driver is informed, the automatic steering operation is terminated, and the driver receives information on the basis of which the driver may continue the driving maneuver.

First claim

What is claimed is:

1. A method for assisting a driver of a motor vehicle during a driving maneuver, comprising:
detecting, by at least one sensor, surroundings of the motor vehicle;
computing, by at least one control unit, based on the detected surroundings, at least one suitable trajectory for carrying out the driving maneuver;
automatically steering the motor vehicle to carry out the driving maneuver to follow the at least one suitable trajectory; and
determining, by the at least one control unit, a malfunction of the motor vehicle, and performing the following steps only if the malfunction occurs: (i) informing the driver of the malfunction; (ii) terminating the automatic steering operation; and (iii) displaying at least a remainder of the at least one suitable trajectory for manually completing the driving maneuver.

2. The method as recited in claim 1 , wherein the automatic steering operation includes automatic longitudinal guidance of the motor vehicle.

3. The method as recited in claim 1 , wherein the malfunction includes at least one of a malfunction of the steering system or a malfunction of the brake system of the motor vehicle.

4. The method as recited in claim 3 , wherein the driver is informed of the termination of the automatic steering operation, by at least one of a visual, acoustic, and haptic indication.

5. The method as recited in claim 3 , wherein the driving maneuver is a parking maneuver into one of a perpendicular parking space or a parallel parking space.

6. The method as recited in claim 3 , wherein for detecting the surroundings of the motor vehicle, distances from objects in the surroundings of the motor vehicle to the motor vehicle are detected, and a surroundings map is created based on the detected distances from objects in the surroundings of the motor vehicle.

7. The method as recited in claim 6 , wherein the surroundings map and the position of the motor vehicle are displayed to the driver.

8. The method as recited in claim 7 , wherein the at least one trajectory for carrying out the driving maneuver is displayed in the surroundings map.

9. The method as recited in claim 8 , wherein the position of the motor vehicle on the trajectory is displayed to the driver.
