The dynamic model and the ground model were built by multi-body dynamics software RecurDyn, and the drive motor control system model was set up by Matlab/Simulink. The dynamic model and control system model were integrated to structure an entire vehicle virtual prototype model. Analyzing and building the strategies of torque adjustment, analyzing the driver's intent, the control logic was built by Stateflow. Based on the virtual prototype, the co-simulation approach and the testing of the prototype were applied to verify the torque control strategies.
