| Abstract: | The 3-DOF automotive steering model and the EPS system dynamics were established,the seamless speed assist mode and flexible PID controller under assistance condition were designed.The controller structure and parameters can be adjusted by determining running status according to the size of control error real-time.The slalom simulation analysis and real vehicle tests were made under 20 km/h,30 km/h and 40 km/h speed respectively.The results showed that the steering handiness was improved respectively compar... |
