The conventional shifting map is developed to enhance the driving performance and fuel economy. According to the driver’s pedaling of accelerator, TCU controls gear ratio in view point of economy ordriving performance. In this paper, various reverse engineering is applied to the driving test results ofheavy duty AMT vehicle. With the test results, the performance of propulsion source is estimated andbasic performance of vehicle is analized. Also the method to derive the shifting schedule according topower or fuel efficient, is developed and compared with the actual shifting map, and various shiftingstates is estimated. The developed numerical analysis model will be a stepping stone for the shift patterndevelopment and various shift control research.
