| Abstract: | A module for converting CAN bus to USB interface is adopted to realize real-time and precise data communications between host computer for calibration and all electronic control units to be calibrated,so the calibration platform has the merits of simple connection,high transmission speed and good function expansibility.The Bayesian algorithm is applied in optimization process so the calibration accuracy is improved with the calibration time shortened.Finally the calibration on a WF4C27F-E gasoline engine is performed,and the MAP graphs of the volumetric efficiency and the spark advance angle are obtained. |
