1、汽车 ABS系统设计毕业论文 汽车 ABS 系统设计毕业论文 题目：汽车 ABS 系统的设计 I 摘 要 ABS (Anti-locked Braking System)系统可以显著提高或改善汽车紧急制动时的操控性 和稳定性，缩短了制动距离，是目前汽车上制动效果最佳的制动装置，并得到了越来越广 泛的应用。 本文以一汽大众速腾汽车为研究对象，展开对汽车 ABS 系统的研究： 通过对单个车轮时的受力分析确定了影响车轮附着系数的主要因素； 通过对控制结构的分析设计了以 INTEL 公司生产的 80C196KC 单片机为核心的实时 控制系统， 包括信号输入电路、 控制输出电路、 驱动电路等硬件部分，
2、并画出电子线路图； 通过设计液压调节系统，画出液压传动原理图，以及系统图； 经比较各种控制方案，确定了逻辑门限控制法作为控制方案，并选用加速度和滑移 率的组合作为控制参数。采用事件门限来计算车轮的转速； 本文通过学习比较根据所学只是设计了 ABS 控制系统。 从理论上实现了 ABS 的控制 功能，完成了设计要求。在设计过程中对汽车制动理论和制动装置有了较为深入的了解， 扩大了自己的知识面，自己解决问题的能力也得到了提高。 关键词：防抱死制动系统 电子控制单元 门限值滑移率 轮速传感器 液压传动控制统 II Abstract ABS (Anti-locked Braking System) sy

4、m of the car: By the time the force analysis on a single wheel of the wheel friction coefficient determined the main factors; Through the analysis and design of the control structure produced by INTEL 80C196KC microcontroller as the core real-time control system, including the signal input circuit,
5、the control output circuit, drive circuit and other hardware parts, and draw circuit diagrams; Through the design of the hydraulic control system, hydraulic schematic drawing, and the system diagram; The comparison of different control schemes to determine the “logic threshold control method“ as the
6、 control program, and use a combination of acceleration and slip rate as the control parameter. Threshold used to calculate the event the wheel speed. By comparison study is designed according to the ABS control school system. Theoretically achieve the ABS control functions to complete the design requirements. In the design process for automotive brake system with brake theory and deeper understanding and expand their knowledge, their problem-solving ability has been improved. Key words: Ant
