摘要： 混合动力电动汽车(HEV)，因采用了起动机/发电机集成 (integrated starter and generator, ISG) 技术，其电子控制单元众多、信息传输量大、安全可靠性要求高。为满足该类混合动力电动汽车对标定、诊断的需求，构建了混合动力网络系统。该系统采用控制器局域网 (controller area network, CAN)总线，融合了通信、标定和诊断等功能；通信协议沿用ISO 11898和Bosch CAN 2.0B的规定；标定网络中，使用了CCP(CAN 标定协议）程序。该系统整车诊断网络完全满足ISO 15765协议，并被成功地应用于中国长安混合动力汽车产业化开发和使用。

Abstract: Chang’an hybrid electrical vehicle (HEV) with integrated starter and generator (ISG) is an industrialized vehicle with more control units, more information transferred among controllers and more safety and reliability than that of conventional one. A network system of hybrid vehicle was designed to meet the requirements of calibration and diagnosis. The network system contains the functions of communication, calibration and diagnosis function based on the controller area network (CAN) bus. The ISO 11898 and CAN 2.0B were used as communication protocols and the CCP (CAN Calibration Protocol) was employed in network calibration. The network system can meet the requirements of the ISO15765 Protocol and has been applied on the develop process and after-sales service for the Chang’an hybrid electric vehicle in China.

Key words: hybrid electric vehicles (HEV), controller area network (CAN), network system, communication, calibration, diagnosis
