Abstract: New energy vehicle CAN bus technology is the core course of new energy vehicle major in colleges and universities. Because of the complexity and abstraction of CAN bus technology, it is very difficult for students to learn. This paper selects the automatic air conditioner of new energy vehicle as the research object, uses WIFI-CAN converter to convert the air conditioner CAN bus data into WiFi data, designs a software to analyze the air conditioner WiFi data in real time, display the air conditioner status, and remotely control the air conditioner through the air conditioner panel on the software interface, which can intuitively demonstrate the automobile CAN bus It can also show the programming process of CAN bus at the source code level, which has great application value for students to master the technology and programming principle of CAN bus.

Key words: New energy vehicle; Air conditioning; CAN bus; WIFI

摘要： 新能源汽车 CAN 总线技术是高校新能源汽车专业的核心课程，由于 CAN 总线技术复杂抽 象，学生学习难度很大。文章选取新能源汽车上的自动空调为研究对象，利用 WIFI-CAN 转换器， 将空调 CAN 总线数据转换成 WIFI 数据，设计一个软件实时解析空调 WIFI 数据，显示空调状态， 并通过软件界面上的空调面板远程控制空调，这既可以直观演示汽车 CAN 总线工作原理，又可以 源代码级展示汽车 CAN 总线的编程过程，对学生掌握汽车 CAN 总线技术及编程原理有很大的应 用价值。
