Abstract
A method for operating a head-up display (HUD) of a vehicle, in which a control device of a vehicle transforms a display image to be displayed by a windshield of the vehicle into a reflection image to be reflected by the windshield and a display unit of a head-up display of the vehicle that is associated with the windshield displays the transformed reflection image, and a control device for a head-up display of a vehicle and a vehicle.
Claims8
A method for operating a heads-up display of a vehicle, comprising:
- a control device of a vehicle transforms a display image to be displayed by means of a windshield of the vehicle into a reflection image to be reflected from the windshield;
- a display unit of the heads-up display of the vehicle associated with the windshield displays the transformed reflection image;
- and
- the control device for transforming the display image determines a warping matrix as a function of a value of a driving speed of the vehicle,
- wherein the speed-dependent determination of the warping matrix comprises at least two constant warping matrices, each associated with predetermined values of the driving speed which are different from one another, and
- wherein the speed-dependent determination of the warping matrix for a value of the driving speed different from each predetermined value of the driving speed comprises an interpolation starting from at least one constant warping matrix associated with one of the predetermined values of the driving speed as a function of the value of the driving speed.

A control device comprising:
- a heads-up display of a vehicle configured to:
- transform a display image to be displayed by means of a windshield of a vehicle into a reflection image to be reflected from the windshield,
- determine a warping matrix for transforming the display image as a function of a value of a driving speed of the vehicle, and
- store at least two constant warping matrices, each associated with predetermined values of the driving speed which are different from one another,
- wherein the speed-dependent determination of the warping matrix for a value of the driving speed different from each predetermined value of the driving speed is interpolated by an interpolation module starting from at least one constant warping matrix associated with one of the predetermined values of the driving speed as a function of the value of the driving speed.
