Abstract

A method for assisting a reverse parking maneuver of a motor vehicle equipped with a rear-view camera system into a longitudinal parking space, wherein the image of the surroundings to the rear of the motor vehicle is displayed on a display of the motor vehicle. For the determination of the parking position on both sides of the vehicle, two 3D symbols, in particular 3D cuboids, are respectively blended into the image of the rear-view camera system, wherein the distance between two 3D symbols corresponds to one side of a minimum parking space for the motor vehicle.

Claims

1. A method for assisting a reverse parking process of a motor vehicle equipped with a rear-view camera system into a longitudinal parking space, the method comprising:

displaying an image of surroundings of the rear of the motor vehicle on a display device of the motor vehicle; and

determining a parking position on both sides of the vehicle by respectively blending two first 3D symbols into the image of the rear-view camera system,

wherein a distance between the two first 3D symbols corresponds to one side of a minimum parking space for the motor vehicle.

2. The method of claim 1, further comprising receiving selection of one side for the parking process, wherein the selection of one side causes the first 3D symbols of the other side of the vehicle to be faded out on the display.

3. The method of claim 2, wherein, in order to determine the initial position, the motor vehicle is moved until the gap between the first 3D symbols corresponds to the longitudinal parking space.

4. The method of claim 3, wherein, after the determination of the initial position in the status of the motor vehicle, a displayed parking frame which is blended into the image of the area to the rear of the vehicle is displaced by orienting the inward steering angle until the parking frame is oriented in the longitudinal parking space, as a result of which a deflection point is defined in the parking frame.

5. The method of claim 4, wherein, after the orientation of the parking frame in the longitudinal parking space, rearward travel is carried out with the selected inward steering angle from the initial position to the deflection point arranged in the parking frame, wherein the actual driving tube is displayed in the image of the area to the rear of the vehicle by means of two blended-in second 3D symbols.

6. The method of claim 5, wherein the setpoint driving path which is defined by the selected setpoint inward steering angle can be displayed in the image of the area to the rear of the vehicle by an auxiliary line.

7. The method of claim 5, wherein the vehicle is requested to stop within a predefined area surrounding the deflection point, and an auxiliary line is made to be congruent with a longitudinal parking space boundary in order to determine an end position.

8. The method of claim 7, wherein, in the image of the area to the rear of the vehicle, an auxiliary line which defines the end point of the following vehicle movement is blended in, wherein the driving tube which is displayed by the blended-in second 3D symbols is made to correspond to the auxiliary line by selecting a new steering angle.

9. The method of claim 5, wherein, in order to assist the driver, further auxiliary lines are blended into the image of the area to the rear of the vehicle.

19. The method of claim 1, wherein the two first 3D symbols are 3D cuboids.

23. The method of claim 5, wherein the two second 3D symbols are 3D guide rails.

10. A method for assisting a reverse parking process of a motor vehicle equipped with a rear-view camera system into a lateral parking space, wherein the image of the surroundings to the rear of the motor vehicle is displayed on a display of the motor vehicle,

wherein, during the reverse parking process the driving tube which is determined by the steering angle is displayed by two 3D symbols blended into the image of the surroundings to the rear of the motor vehicle.

11. The method of claim 10, wherein, in addition to the 3D symbols, a distance grid is blended in, which assists the driver in orienting the motor vehicle.

21. The method of claim 10, wherein the two first 3D symbols are 3D cuboids.

24. The method of claim 10, wherein the two second 3D symbols are 3D guide rails.

12. A device for carrying out a method for parking a motor vehicle in a longitudinal parking space, the device comprising a rear-view camera system and a display for displaying the image of the surroundings to the rear of the motor vehicle taken by the rear-view camera system,

wherein the device has an apparatus for generating and blending first 3D symbols into the image of the surroundings to the rear of the motor vehicle displayed on the display in order to determine the parking position, wherein on each side of the vehicle two first 3D symbols are displayed, the distance between which symbols corresponds to the minimum parking space for the motor vehicle.

13. The device of claim 12, wherein the device has an apparatus for generating and blending a parking frame into the image of the surroundings to the rear, wherein, in the identified parking position of the motor vehicle, the parking frame is displaced into the identified longitudinal parking space as a function of the steering angle, as a result of which a deflection point is defined in the displaced parking frame.

14. The device of claim 13, wherein the device has an apparatus for generating and blending second 3D symbols into the image of the surroundings to the rear of the motor vehicle, wherein the second 3D symbols display the driving tube of the motor vehicle during the parking process.

15. The device of claim 14, wherein the device has an apparatus for generating and blending further auxiliary lines into the image of the surroundings to the rear of the motor vehicle in order to assist the driver during the parking process.

16. The device of claim 12, wherein the device has an estimating unit for estimating the driving path expected to be travelled along.

18. The device of claim 16, wherein the device has an apparatus for generating and blending further auxiliary lines into the image of the surroundings to the rear of the motor vehicle in order to assist the driver during the parking process.

20. The device of claim 12, wherein the two first 3D symbols are 3D cuboids.

17. A device for carrying out the method for parking a motor vehicle in a lateral parking space, having the device comprising a rear-view camera system and a display for displaying the image of the surroundings to the rear of the motor vehicle taken by the rear-view camera system,

wherein the device has an apparatus for generating and blending 3D symbols into the image of the surroundings to the rear of the motor vehicle, wherein the 3D symbols display the driving tube of the motor vehicle during the parking process.

22. The device of claim 17, wherein the two first 3D symbols are 3D cuboids.
