| 摘 要： | 为了改善驾驶员在夜间或能见度较低环境下的视野范围，提高行驶的安全性，介绍了一种基于嵌入式系统的汽车自适应前照灯系统的设计方案。此系统中的前照灯控制器采用FPGA来控制CAN总线控制器、数／模转换器和全桥电机驱动器等器件来实现接收方向盘转角信号，并使电机运行带动前照灯的转向。自适应前照灯系统控制中心使用的是ARM9处理器。该设计方案满足要求，已经在项目中获得了良好的应用效果。

| Abstract: | In order to improve the vision scope of the driver at night or in low visibility environments and to improve the driving safety, a design of automotive adaptive headlamp system based on embedded system is introduced. In this system, front lighting controller uses FPGA to control these devices such as CAN bus controller, digital to analog converter and motor drive device of the whole bridge to a- chieve receiving steering wheel angle signals, and it makes the motor run to carry on the front-light steering. The control center＇s pro- cessor of adaptive front lighting system adapts ARM9 processor. The design meets the requirements, and it has obtained the good application effect on the project. |
