摘要
主要探讨了汽车和电动汽车数字化技术、计算机控制系统的结构以及现场通讯的相关问题。以蓄电池能源系统为应用背景,研究和设计出采用双CAN总线作为内外通讯方式及具有多模块分布式结构的管理系统。该系统分为若干模块,分别实现各自独立的功能,包括数据采集、测量多路电压、电流和温度、进行电量估算和通讯管理以及大液晶屏的显示。为满足系统发展所需要的高性能、安全性和可扩展的要求,提出双CAN总线通讯、分布处理的管理系统结构思想。重点介绍了CAN总线设计、电路和应用的技术问题。
The digital technology of vehicle and electronic vehicle (EV), with the emphasis on the structure of the system controlled by computer and something about the communication are mainly discussed The management system which has been studied and designed uses double CAN(Controller Area Network) bus as its interior and exterior communication method. The system adopts distributed structure and consists of several modules, each of which realizes its special function, such as data collection, the measure of multi loop voltage, current and temperature, the computing of the SOC(State of Charge), the management of communication and liquid-crystal display.
In order to fulfill the need of high performance, security and extend for the system, some ideas, including communication with double CAN bus and distributed process are putted forward. The CAN bus design, the circuit and the technological problem in the application of CAN bus are also discussed.
