摘要
针对汽车追尾事故所带来的严重危害,本文运用现代传感技术、激光测距雷达等技术设计了以ARM为控制核心、DSP为数据处理核心的双处理器架构的汽车防追尾控制系统。介绍了系统的工作原理、设计了整个硬件结构,并在此基础上对两车间的安全距离算法以及模糊算法进行了研究。最后,通过Matlab的仿真,结果表明该系统在防止汽车追尾的问题上切实有效。
In view of the serious damage brought by rear-end collision, we adopt ARM as control core, DSP as data processing core and design the automobile anti-rear-end collision control system with dual processor architecture by applying modern sensor technology and laser ranging radar technology. We introduced the principle of the system and designed the hardware structure. Furthermore, the safe distance algorithm between two cars and fuzzy algorithm are studied. Finally, the simulation results through Matlab show that the system is practical and effective in preventing rear-end collision.
