Response speed is the key to advanced vehicle dynamic testing. A new kind of testing system was put forward based on direct torque control which takes response speed into full consideration. Then a sim-ulation model was established according to it. In the design, vehicle motion inertia is simulated by the way of electrical inertia instead of mechanical inertia. Because direct torque control has quick response to torque com-mand, the acceleration of vehicle is kept in accurate control using electrical inertia. The simulation results show that the performance is ideal.
