Abstract

In a method for displaying information in a motor vehicle, at least one two-dimensional object is displayed graphically in a first representation which shows one side of the object, and in a second representation which shows the other side of the object, with the aid of a display mounted in the motor vehicle, different information being shown on the respective sides of the two-dimensional graphical object, and the graphical object extending substantially over the entire size of the display in at least one direction in the first and/or second representation. The representation of the graphical object is altered as a function of a control signal such that the graphical object rotates from one side to the other side in a perspective representation on the display, the two-dimensional graphical object always being fully displayed, at least perspectively, during the rotation. A corresponding display device for a motor vehicle is provided for performing the method.

Claims

1-17. -17. (canceled)

18. A method for displaying information in a motor vehicle, comprising:

graphically displaying, in a display mounted in the motor vehicle, at least one two-dimensional object in a first representation which shows one side of the object and in a second representation which shows another side of the object, different information being shown on the respective sides of the two-dimensional graphical object, in at least one of (a) the first and (b) second representation, the graphical object extending substantially over an entire size of the display in at least one direction; and

altering the representation of the graphical object as a function of a control signal to rotate the graphical object from one side to the other side in a perspective representation on the display (1);

wherein the two-dimensional graphical object is always fully displayed, at least perspectively, during the rotation.

19. The method according to claim 18, wherein the control device alters the graphic data such that the graphical object is rotated about a vertical axis, which at least at a beginning of the rotation, at least one of (a) is outside of the graphical object and (b) extends through a laterally outermost point at an edge of the graphical object.

20. The method according to claim 19, wherein the control device alters the graphic data such that the vertical axis is shifted in a horizontal direction during the rotation, and at the same time, the graphical object is rotated about the vertical axis, so that after a rotation of 180°

, the vertical axis has reached a position in the second representation.

21. The method according to claim 19, wherein the control device alters the graphic data such that a horizontal shift of the vertical axis is synchronized linearly with the rotation of the graphical object.

22. The method according to claim 18, wherein the rotation is subdivided into a first phase in which pixels of the graphical object are moved in accelerated fashion, and a second phase in which pixels of the graphical object are moved in decelerated fashion.

23. The method according to claim 22, wherein the first phase corresponds to an angle of rotation of the graphical object from 0°

to 90°

, and the second phase corresponds to an angle of rotation of the graphical object from 90°

to 180°

.

24. The method according to claim 22, wherein the following computations are carried out in calculating the graphic data for successive intermediate images to represent the rotation in the first phase:

25. The method according to claim 22, wherein the following computations are carried out in calculating the graphic data for successive intermediate images to represent the rotation in the second phase:

26. The method according to claim 18, further comprising:

measuring a speed of the motor vehicle; and

ascertaining at least one of (a) a duration of a total rotation and (b) a duration of a rotation of at least one of (i) a first phase and (ii) a second phase as a function of the speed of the motor vehicle.

27. A display device for a motor vehicle, comprising:

a display mounted in the motor vehicle and adapted for graphical representation of information; and

a control device adapted to generate graphic data that represent at least one two-dimensional graphical object, displayable on the display, in a first representation which shows one side of the object, and in a second representation which shows another side of the object, different information being shown on the respective sides of the two-dimensional graphical object, in at least one of (a) the first representation and (b) the second representation, the graphical object extending substantially over an entire size of the display in at least one direction;

wherein the control device is adapted to alter the graphic data to rotate the graphical object from one side to the other side in a perspective representation on the display, the two-dimensional graphical object always being fully displayed, at least perspectively, during the rotation.

28. The display device according to claim 27, wherein the control device is adapted to alter the graphic data to rotate the graphical object about a vertical axis, which at least at a beginning of the rotation, at least one of (a) is outside of the graphical object and (b) extends through a laterally outermost point at an edge of the graphical object.

29. The display device according to claim 27, wherein the control device is adapted to alter the graphic data to shift a vertical axis in a horizontal direction during the rotation, and at the same time, to rotate the graphical object about the vertical axis, so that after a rotation of 180°

, the vertical axis has reached a position in the second representation.

30. The display device according to claim 27, wherein the rotation is subdivided into a first phase in which pixels of the graphical object are moved in accelerated fashion, and a second phase in which pixels of the graphical object are moved in decelerated fashion.

31. The display device according to claim 30, wherein the control device is adapted to perform the following computations to calculate the graphic data for successive intermediate images to represent the rotation in the first phase:

32. The display device according to claim 30, wherein the control device is adapted to perform the following computations to calculate the graphic data for successive intermediate images to represent the rotation in the second phase:

33. The display device according to claim 27, wherein the display device includes an interface adapted to receive data relating to a speed of the motor vehicle, the control device adapted to ascertain at least one of (a) a duration of a total rotation and (b) a duration of the rotation for at least one of (i) a first phase and (ii) a second phase as a function of the speed data.

34. A motor vehicle, comprising:

a display device including;

a display adapted for graphical representation of information; and

a control device adapted to generate graphic data that represent at least one two-dimensional graphical object, displayable on the display, in a first representation which shows one side of the object, and in a second representation which shows another side of the object, different information being shown on the respective sides of the two-dimensional graphical object, in at least one of (a) the first representation and (b) the second representation, the graphical object extending substantially over an entire size of the display in at least one direction;

wherein the control device is adapted to alter the graphic data to rotate the graphical object from one side to the other side in a perspective representation on the display, the two-dimensional graphical object always being fully displayed, at least perspectively, during the rotation.
