【Abstract】 Advantages of ve-DYNA software on control and realtime simulation are introduced in the paper. The vehicle dynamic simulation model for analysis of the electric steering system of a car is created. Torque on the steering wheel at different speeds is simulated and the expected speed-responding power steering characteristic curve is obtained, which found basis for further development of electric motor control and ECU.更多还原
