摘要:
介绍通用诊断协议ISO14229和基于CAN总线的车辆故障诊断协议ISO15765,分析两者之间的关系及ISO15765的体系结构,在此基础上给出ISO15765协议栈总体设计,并描述协议每一层的软件实现。协议栈设计利用分层接口方式,下层向上层提供服务,协议内部功能采用模块化设计。实验结果表明,该协议栈能满足ISO15765规定的标准和一般的故障诊断功能需求。

Abstract:
ISO14299 specifying unified diagnostic services and CAN based vehicle fault diagnostic protocol ISO15765 are introduced, and the relationship between ISO14229 and ISO15765 and the architecture of ISO15765 are analyzed. The overall design of the ISO15765 protocol stack is provided in the paper. The design of the ISO15765 protocol stack uses layered and interface method. Lower layers provides services to higher layers. Modular design is adopted for developing internal operation. Experimental results show that the protocol stack satisfies ISO15765 standard and general fault diagnosis requirements.
