The principle of rotor flux-orientation vector control on 100/150 kW three-phase AC induction motor for electric transmission tracked vehicle was analyzed, the mathematic model was deduced. The modeling and simulation on the driving system of induction motor were completed by Matlab/ Simulink. The characteristics of motor and driving system were analyzed and evaluated in detail by practical bench test. The simulation and bench test results show that the model is valid and the driving control system has constant torque under rated speed, constant torque above rated speed, widely variable speed range and better dynamic performance. In order to evaluate the practical applications of high power induction motor driving system on electric transmission tracked vehicle, collaborative simulation based on interface technology of Matlab/Simulink and multi-body dynamics analysis software known as RecurDyn was done, the vehicle＇s performances about the acceleration time（0--32 km/h） and turning characteristic （v = 10 km/h, R = B） forecasted.
