CANOE在OBD验证测试中的应用

Application of CANOE in OBD Verification Test

随着国六排放法规的落地,OBD相关法规越来越严格,对于整车企业来说,OBD系统的验证工作就显得十分必要。随着网络技术的发展,现代汽车各电控系统之间数据传输多采用CAN总线,通过总线连接解决了原有复杂的数据传输问题。文章结合CAN网络系统组成和性能特点,阐述了CAN网络在汽车领域的应用优势,并介绍了如何使用CANOE软件进行OBD系统中CAN节点的故障诊断的验证测试,为OBD系统开发和后续诊断维修提供了便利。

With the implementation of CN6 emission regulations,the relevant regulations of OBD are more and more strict.For vehicle enterprises,the verification of OBD system is very necessary.With the development of network technology,the data transmission between modern automobile electronic control systems mostly adopts CAN(Controller Area Network),which solves the original complex data transmission problem.Combined with the composition and performance charac-teristics of CAN network system,this paper expounds the application advantages of CAN network in automobile field,and introduces how to use CANOE software to verify and test faults diagnosis of CAN nodes in OBD system,which provides convenience for the development of OBD system and subsequent diagnosis and maintenance.
