Abstract In order to address the customer complaint the fuel consumption of an automatic transmission vehicle, the calibration data of both engine and the automatic transmission are analyzed in detail. It is found that the cut-off of vehicle deceleration fuel, automatic transmission gear-shifting curve, and engine idle speed can be optimized to reduce the fuel consumption of the vehicle through calibration optimization. Compared with the original calibration, the new calibration greatly reduces the fuel consumption both on the actual urban driving condition and the NEDC cycle.
