Simulation study on starting of dual clutch transmission for tracked vehicles

In order to study the application of dual clutch transmission (DCT) on tracked vehicles, a simulation model and two control methods were performed for starting analysis. Based on a certain transmission of an existing tracked vehicle, a DCT structure was proposed. Matlab/Simulink was adopted as a platform to develop the simulation model. The engine speed was controlled to follow the target speed as a launch strategy. Two control methods, a proportional-integral-derivative (PID) control method and a fuzzy control method, were proposed to control the engine throttle and oil pressure in order to track the target engine speed. Simulation results show that either the PID control or fuzzy control method can improve the starting performance compared with no loop control method. Fuzzy control method can lead a better starting quality compared with PID control method.
