Simulation and Analysis of Engine Speed Coordinated Control during TC + AMT Transmission Shifting Process

Abstract:

Coordinated engine control is an essential technology to improve shift quality. The influence of wet clutches’ towing torque in TC+AMT on shift synchronization process is analyzed, and a coordinated engine speed control strategy is proposed. Wet clutches’ towing torque and AMT shift synchronization process simulation models as well as the engine speed controller are developed by using MATLAB/Simulink. Finally the simulation of TC+AMT shifting process with wet clutches under engine speed coordinated control is carried out. The simulation results show that wet clutches’ towing torque can be used to reduce shift synchronization time, synchronization energy and the wear and tear of synchronizer as well as improving shift quality.
