摘　　要：控制器局域网(Controller Area Network,CAN)是一种能够支持分布式控制和实时控制的串行通信网络,广泛应用于汽车电子系统中。在总线上,数据以报文形式在网络中广播,节点则通过收发器接收数据,并由控制器校验是否为目标数据。本文对某车型开发实车测试中遇到的过载帧现象进行了深入分析,总结了过载帧产生的原因。通过详细剖析过载帧案例,本文为后续测试工作中类似问题的分析与解决提供了理论支持和实践指导,以期提高CAN总线系统的稳定性与通信效率。CAN(Controller Area Network)is a serial communication network that supports distributed control and real-time control,widely used in automotive electronic systems.Data on the bus is broadcast across the net‐work in the form of messages.Nodes receive the data via transceivers,and the controller verifies whether it is the intended data.This paper provides an in-depth analysis of the overload frame phenomenon encountered dur‐ing in-vehicle testing in the development process of a specific vehicle model and summarizes the causes of the overload frames.Through detailed analysis of the overload frame cases,this paper offers theoretical support and practical guidance for addressing similar issues in subsequent testing efforts,with the goal of improving the sta‐bility and communication efficiency of the CAN bus system.
