基于车载以太网的刷写过程问题故障诊断案例

Fault Diagnosis Case of Flashing Process Problems Based on Onboard Ethernet

随着车载以太网的逐渐普及,应用场景也越来越多。在主机厂,总装线体会在电检工位进行诊断、刷写、检测、维修。售后市场也会存在检测、维修,呈现多种多样的故障类型。文章通过借用Wireshark的TCP分析器跟踪每个TCP会话的状态,对TCP数据包常见问题结构进行剖析。

With the gradual popularization of in car Ethernet,the application scenarios are also increasing.In the host factory,the final assembly line will be diagnosed,flashed,inspected,and repaired at the electrical inspection station;The after-sales market also involves detection and maintenance,presenting a variety of fault types.This article analyzes the common problem structures of TCP packets by borrowing Wireshark's TCP analyzer to track the status of each TCP session.
