It is difficult to provide assistant torque reasonably using the conventional EPS control when road adhesion coefficient changes. An EPS control with a regulating factor was proposed to solve the problem mentioned above. It can adjust vehicle speed inductance through the regulating factor to achieve that assist characteristic changes with the changes of road adhesion coefficient. Furthermore, it can enhance the self-adaptive ability of EPS. It is approved that the assistant torque could be adjusted reasonably and effectively by the regulating factor, based on the simulation.
