一种车载CAN总线监控系统的仿真及设计

Design of an on-board CAN-bus monitoring system

文中设计一种车载CAN总线协议的监控系统,用于实时显示汽车运行状态以及报警信息。以大众斯柯达轿车为对象,通过CAN总线诊断仪和CAN分析仪,分析汽车发动机系统中不同参数的CAN通信帧信息,解析出这些参数的通信协议。在该协议的基础上,验证了CAN总线监控系统应用的可行性。

This paper designs an onboard CAN-bus protocol monitoring system for real-time display of vehicle operation status and alarm information.With Volkswagen skoda cars as the object,through CAN bus diagnosis instrument and CAN analyzer,the analysis of different parameters of CAN communication in automotive engine system frame of information,communication protocol parsing out these paramet.On the basis of this agreement,the feasibility of the application of CAN-bus monitoring system is verify.
