The Research of CAN Bus in the Car Intelligent Lighting Control System

As one of the most important subsystem of automotive control systems, the design of automotive lighting control system is essential. In this article, the automotive intelligent headlight control system based on CAN bus was introduced, and the system hardware structure and software design processes was given. Adopted MC9S08DZ60 microcontroller which integrated the CAN controller as the master chip. While taking advantage of the photoelectric sensor to analyze road lighting conditions, according to light changes in the external environment to achieve automatic dimmer. The circuit has characteristics of simple hardware design, high reliability and real-time. And provided a theoretical basis for the Hyundai Motor intelligent control system.
