In order to reduce the high development cost and technical difficulties, this article develops Hardware-in-the loop （HIL） simulation for Advance Front-lighting System （AFS）. On the basis of xPC general scheme, the simulation model is constmcted by utilizing modular modeling method, and graphical user interface is driven by S-function technique, the goal is to solve real - time monitoring problem in Hardware-in-the loop（HIL） simulation process. With a series of simulation testing, the conclusion indicates that this system can confirm and evaluate the feasibility of Advanced Front-lighting＇ s control algorithm and the performance of the software and hardware, which laid the foundation for calibration and test of AFS.
