Method of operating a vehicle head-up display
A method of controlling a head-up display (HUD) of a vehicle to adjust the vertical position of a light bundle generated by the HUD to match an eye of a vehicle driver. A camera is operated to capture an image of a head of the vehicle driver reflected in a combiner of the head-up display. An electronic processor analyzes the image captured by the camera and determines a position of a driver's eye. The processor controls operation of an electric motor to automatically adjust the position of the combiner to align a light bundle or eyebox generated by the projector and reflected by the combiner with the eye position determined by the processor.
1. A method of controlling a head-up display of a vehicle comprising:
operating a camera to capture an image of a head of a driver reflected in a combiner of the head-up display;
operating a processor to analyze the image to determine a position of an eye of the driver; and
automatically adjusting a position of the combiner to align a light bundle generated by the projector and reflected by the combiner with the position of the eye.
2. The method of claim 1 , wherein the combiner comprises a screen located between a windshield of the vehicle and the head.
3. The method of claim 2 , wherein the position of the combiner is adjusted by operating a motor to pivot about an axis aligned transverse relative to the vehicle.
4. The method of claim 1 , wherein the method is carried out when the vehicle is started up.
5. The method of claim 1 , wherein the method is carried out during a trip of the vehicle.
6. The method of claim 1 , further comprising illuminating the head with light having a wavelength which is invisible to a human eye and is visible to the camera.
7. A method of controlling a head-up display of a vehicle comprising:
operating a camera to capture an image of a head of a driver reflected in a combiner of the head-up display;
operating a processor to analyze the image to determine a position of an eye of the driver; and
automatically adjusting a position of the combiner to align an eyebox generated by the head-up display with the position of the eye.
8. The method of claim 7 , wherein the combiner comprises a screen located between a windshield of the vehicle and the driver's head.
9. The method of claim 8 , wherein the position of the combiner is adjusted by operating a motor to pivot about an axis aligned transverse relative to the vehicle.
10. The method of claim 7 , wherein the method is carried out when the vehicle is started up.
11. The method of claim 7 , wherein the method is carried out during a trip of the vehicle.
12. The method of claim 7 , further comprising illuminating the head with light having a wavelength which is invisible to a human eye and is visible to the camera.
13. A method of operating a vehicle head-up display comprising:
operating a camera to capture an image of a head of a driver reflected by a combiner of the head-up display;
operating a processor to determine a position of an eye of the driver from the image; and
automatically adjusting a position of the combiner to align an eyebox produced by the head-up display with the position of the eye.
14. The method of claim 13 , wherein the combiner comprises a screen located between a windshield of the vehicle and the driver's head.
15. The method of claim 14 , wherein the position of the combiner is adjusted by operating a motor to pivot about an axis aligned transverse relative to the vehicle.
16. The method of claim 13 , wherein the method is carried out when the vehicle is started up.
17. The method of claim 13 , wherein the method is carried out during a trip of the vehicle.
18. The method of claim 13 , further comprising illuminating the head with light having a wavelength which is invisible to a human eye and is visible to the camera.
