Adaptive Front Lighting System Using CCD

Abstract

The Adaptive Front-lighting System (AFS) is one part of the active safety system of a middle-high end passenger car, providing an optimized vision to the driver during night time and other poor-sight conditions of the road by adapting the headlight angle and intensity, and judging the speed of the car, the steering wheel angle, the weather condition, and yaw and tilt rate of the car. To facilitate a user's development of such a system and to demonstrate the performance of TI's automotive MCU family, a reference design of AFS is developed. This article describes the functions of the reference design, as well as the implementation. Furthermore, it states the guidelines for manipulating the demonstration of the reference design.
