Research on Hardware-in-the-Loop Simulation for Advanced Front-Lighting System

Due to the poor adaptability of the traditional vehicle headlights under some conditions such as vehiclepsilas speed at night, road type and weather situation, the Advanced Front-lighting System (AFS) has been widely concerned in the world. Based on the analysis of the advanced front-lighting´s related characters and the hardware-in-the-loop´s significance, the hardware-in-the-loop simulation for AFS based on the xPC technology was researched and developed. The modular simulation model is established, as well as the adjustment strategy of headlight in the horizontal plane and the vertical plane are built, to provide the driver with the best possible visibility and enhance driving safety by varying lighting distribution. With a series of simulation testing, the conclusion is indicated that this system has the good function of the hardware-in-the-loop simulation for AFS, it can be to confirm and evaluation the feasibility of advanced front-lightingpsilas control algorithm and the performance of the software and hardware, to reduce the repeated real object experiment and the danger, which is lay the foundation for calibration and test of AFS.
