| Abstract: |
| According to the tire cornering characteristics,the EPS system dynamics model is established from any steering angle of the car, on which the model parameters on the zero stability of the EPS system dynamics model is analyzed by constructing Lyapnuon function. Combined with the actual characteristics of the car steering parts, the sufficient conditions is given for the model zero stability.The critical instability speed of the EPS system can be determined in accordance with the conditions and structural parameters of the given vehicle model, which provides a theoretical basis for EPS research and development. |
