Example Embodiment
[0043] Example 1
[0044] Taking a manual transmission model as an example, the control variable method is used, and the subjective driving experience is used as the evaluation method to calibrate the torque rate MAP table:
[0045] a. 0% throttle start, that is, control the required torque, slowly lift the clutch, feel the stumbling feeling when the clutch is engaged and the starting performance of the vehicle after engagement;
[0046] b. Analyze the data, adjust the torque rate value corresponding to the required torque (assumed to be 20Nm) corresponding to the 0% throttle in MAP Table 1 and Table 2, repeat the operation a, and evaluate the stumbling feeling when the clutch is engaged and the starting performance after the combination;
[0047] c. Repeat operations a and b until the supervisor feels satisfied and reasonable;
[0048] d. Use 10%, 20%, 30%...100% throttle to start, repeat steps a, b, and c to get a reasonable torque rate MAP table 1 and table 2.
