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.
