基于发动机ECU开发的双路并行 系统参量获取技术研究. (Chinese)

Based on the engine dual parallel ECU system test platform, carried out on the research and development on parame ter real time acquisition technology from P-ECU to V-ECU. Through in depth study of CCP protocol and calibration system IN-CA working principle, under the normal operation of P-ECU control engine, according to the DAQ function provided by the CCP protocol, send a series of CCP protocol command to P-ECU through the V-ECU. configure the DAQ list in P ECU. enable the DAQ function of P-ECU. and then the P-ECU internal parameters are accessed and used flexible in high speed. The experiment shows that the system can meet the optimization requirements of the engine ECU control algorithm and can improve the optimization efficiency remarkably, and lay the foundation for continuously optimizing the V-ECU internal self developed control algorithm to make the V-ECU to achieve the original P-ECU level in engine control.
