为了提高汽车行驶的安全性,文章介绍了汽车防撞的软件决策系统和硬件电路设计。软件决策部分主要对提出的三种算法进行比较,得出驾驶员预估模型报警算法比较合理,但此算法两个重要参数τ和aτ对结果的影响较大,因此对两个参数的获取也进行了详细介绍;硬件部分关键技术为超声波测距,选择三星公司的S3C2410为核心处理器,保证了硬件系统的稳定性和反应速度。
In order to improve the safety of vehicle driving, the article introduces the software design system and hardware circuit design of automobile collision avoidance. The software decision-making part mainly compares the three algorithms proposed, and draws the driver prediction model alarm algorithm is more reasonable, but the algorithm of two important parameters τ and aτ greater impact on the results, so the two parameters are also obtained Has carried on the detailed introduction; The key technology of the hardware part is the ultrasonic distance measurement, chooses the Samsung Corporation S3C2410 as the core processor, has guaranteed the hardware system stability and the response speed.
