| Abstract: | The main structure and operating principle of EPAS were described,the EPAS model was simplified,EPAS mechanism dynamics equation was established,the transfer function equation of steering sensitivity under the current proportion control strategy was deduced,and the simulation computation in the Matlab were carried out,and qualitative elaborated the influence of systematic response characteristics when the same structural parameters was applied to EPAS under the condition of steering wheel angle step input. |
