基于ADSP-BF561的车辆辅助驾驶系统硬件设计

Hardware design of Driver Assistance System Base on ADSP-BF561

本文介绍基于ADSP-BF561的车辆辅助驾驶系统硬件设计,根据系统设计要求,搭建最小系统和扩展电路,并实现通过CCD摄像机进行实时视频采集。经过视觉处理算法后,将计算结果发送至CAN总线上,辅助驾驶策略控制单元最终根据危险程度的大小提示驾驶员或控制车辆的油门和制动。其硬件设计包括最小系统电路、并行输入/输出外围接口外围电路、CAN模块电路等,为搭建整个车辆辅助驾驶系统提供可靠的硬件基础和系统框架基础。

Hardware design of Driver Assistance System Base on ADSP-BF561 is introduced. According to the requirement of me system, the minimal system and extension circuit had been designed. And the real-time video capture realizes by CCD camera. After the processing algorithms of vision finished, processing results are send to CAN Bus, and then the ECU of Driver Assistance System will warn the driver or control the throttle and brake based on danger level. The hardware design included the minimal system circuit, Parallel Peripheral Interface circuit, CAN module circuit and so on. It offers hardware and system framework foundation for the whole Driver Assistance System.
