基于目标油门开度预估的AMT汽车起步控制

摘要

A kind of Method of AMT Automobile permanent rev starting control with opening prediction of target accelerograph. Being different requirement to shock degree of the process above in different opening, the modified prediction of final opening is regarded as the target accelerograph opening to control, hence a table for target control of air damper opening change rate and clutch engaging speed. The results show that the method can improve greatlv the starting control qualitv.%建立了一种带目标油门开度预估的AMT汽车恒转速起步控制方法。由于不同油门开度下AMT汽车起步过程冲击度的不同要求，通过油门踏板开度变化率对目标油门开度进行预估，将预估并加以修正的最后油门开度作为目标油门开度进行控制，从而制定出节气门开度变化率和离合器接合速度的目标控制数表。预估前后结果表明，带目标油门开度预估的控制方法，可使AMT汽车特定工况的起步控制品质明显改善。
