The invention discloses a vehicle-mounted controller fault analysis system and method, and the system comprises an assembly receiving and transmitting module and an upper computer, the assembly receiving and transmitting module is used for connecting a to-be-tested vehicle and receiving a to-be-tested message of the to-be-tested vehicle, and the to-be-tested message comprises all sub-function messages in operation items of the to-be-tested vehicle; the upper computer receives a to-be-tested message through the connection assembly receiving and transmitting module, the upper computer comprises a simulation module, an analysis module and a comparison module, the simulation module is used for simulating an operation item corresponding to the to-be-tested message to generate a reference message, and the reference message comprises all sub-function messages in the simulation operation item; the analysis module generates a time sequence-based reference process file based on the reference message and generates a time sequence-based to-be-tested process file based on the to-be-tested message, and the comparison module is used for comparing the reference process file with the to-be-tested process file so as to determine a fault signal in the to-be-tested process file and output a message sender corresponding to the fault signal.

    本发明公开一种车载控制器故障分析系统及方法,包括总成收发模块和上位机,总成收发模块用于连接待测车辆,并接收待测车辆的待测报文,待测报文包括待测车辆的操作项目中的全部子功能报文;上位机通过连接总成收发模块接收待测报文,上位机包括仿真模块、解析模块和比较模块,仿真模块用于仿真待测报文对应的操作项目生成参考报文,参考报文包括仿真操作项目中的全部子功能报文,解析模块基于参考报文生成基于时序的参考过程文件,同时基于待测报文生成基于时序的待测过程文件,比较模块用于比较参考过程文件和待测过程文件,以确定待测过程文件中的故障信号,并输出故障信号对应的报文发送方。
