摘　　要：LIN通信是基于UART/SCI的一种低成本、低速率的串行通信网络;采用单主控器/多从设备模式,只需单回路即可实现数据的传输与信息反馈,多用于汽车舒适系统。本文针对某重型卡车多功能方向盘LIN开关通信故障进行分析,并给出解决方案,最后通过试验验证来证明方案的可行性,为后续LIN开关设计提供经验。LIN communication is a low-cost and Low-speed serial communication network based on UART/SCI data format;Single master/multi slave mode is adopted,which can realize data transmission and information feedback with only a single loop,which is mostly used in automobile comfort system.This paper analyzes the communication fault of Lin switch in the multi-functional steering wheel of a heavy truck,and gives the solution.Finally,the feasibility of the scheme is proved by experimental verification,which provides experience for the subsequent Lin switch design.
