摘要：Test load is important in the test of the automotive steering system which greatly influences the test results. In this paper, different simulation methods for steering load were reviewed, and a new test bench for steering system was introduced, and the emphasis was on the steering load simulation and its control system. An AC servo motor was used as loading motor, which is controlled by a computer. Matlab/Simulink/Real-Time Windows Target (RTWT) is used to model the system and calculate the steering load, and the control signal is sent to the AC servo motor. The angle signals of the steering wheel and the motor are feed back to the computer. Tests were conducted to verify the performance, and an automotive electric power steering device was tested on the bench. Test results showed the test bench worked well, and the design of control system is high efficient, powerful and easy to use.
