Abstract
A headlamp system stores a plurality of beam patterns on a microprocessor 32 that selects a predetermined beam pattern based on driving conditions and sends the predetermined beam pattern to a digital micromirror device (DMD) 18 that is capable of generating the desired beam pattern by adjusting the position of individual pixels on the DMD 18. Several vehicle parameters are inputs 36, 37, 38, 29, 70 to the microcontroller 32 and are used to determine the appropriate beam pattern to be produced by the DMD 18 and projected by the headlamp system of the present invention.
