Tracked vehicle runs under dynamic condition frequently. Due to the inner complex physical and chemical changes in the course of engine operation, its system model are highly non-linear, so it is difficult to obtain the precision of model by means of mechanism modeling. To meet the requirement of making automatic shift schedule, the best power shift schedules of a tracked vehicle are deduced in this paper. The dynamic simulation model of drivetrain of tracked vehicle is created in Matlab/Simulink, and the fuzzy shift controller is designed using fuzzy logic. Then it simulates dynamic performance and shift of vehicle. The results of simulation truly and exactly show the stable processing without shift loop; they also improve efficiency of torque converter and dynamic performance of vehicle.
