Abstract


With the electronic control unit (ECU) on the engine in the car wide application associated with calibration, monitoring and fault diagnosis technology has become the key technology of automobile engine , the current mainstream solutions are widely dependent on foreign countries, committed to the development of this project efficient automotive electronic control engine calibration , monitoring and diagnostic tools in order to serve the domestic automotive engine electronic control unit and the developer. This article focuses on the calibration of monitoring and fault diagnosis system design , the main work includes design PC software tool designed ECU side related program modules, system performance testing engine as well as specific application experiments . In the realization of real-time monitoring of engine calibration and functionality can be extended using the CAN bus calibration protocol CCP, presented ECU description file based engineering methods to facilitate the realization of the system for the calibration object independence. The system functions in the user authentication to achieve the operating engineers , MAP calibration, engine running real-time monitoring, simple Downline Management (EOL) , and Flash -related operations functions , in addition, the system is compatible standards that meet the ASAP2 description file A2L ECU operating functions , greatly enhance the system's versatility. In the engine fault diagnosis , this paper SAEJ1939 standard design based diagnostic tool specifically designed to discuss the application layer functions , diagnostic tasks trigger mode , the bus network management and fault indicator control . Finally, the designed system functional testing , through mathematical modeling and experimental analysis verify the efficiency of communication systems , communication reliability and real-time communication and calibration, real-time monitoring and diagnostic capabilities of concrete used in diesel engine electronic control rail systems , given the end of the rail system ECU calibration , monitoring, and diagnostics module design for the engine bench test . Preliminary experimental results show that the technology developed for the engine electronic control unit capable of providing a powerful tool for development .
