为了改善汽车动力学性能和辅助安全驾驶,将ABS,ASR,ACC系统进行有机的综合.根据三者功能上的异同点,提出了ABS/ASR/ACC集成控制策略和切换逻辑.为了便于算法调试,开发了基于CAN总线的车载实验平台.应用模块化的思想,分析了各个子模块的功能,制定了平台内部通信协议,完成了车载平台的软硬件设计.实车实验表明:车载实验平台为集成控制系统的研究提供了良好的开发环境和技术基础,同时ABS/ASR/ACC集成控制系统能有效提高汽车纵向行驶中的主动安全性能.
In order to improve the dynamic performance of the vehicle and assist the safe driving, the ABS, ASR and ACC systems are organically integrated. According to the similarities and differences of the three functions, the integrated control strategy and switching logic of ABS / ASR / ACC are proposed. , Developed a vehicle-mounted experimental platform based on CAN bus.Using the idea of modularization, the function of each sub-module was analyzed and the protocol of internal communication of the platform was established and the hardware and software design of the vehicle-mounted platform was completed.Experimental results show that: The research of integrated control system provides a good development environment and technical basis. Meanwhile, the integrated control system of ABS / ASR / ACC can effectively improve the active safety of the vehicle in the longitudinal driving.
