针对常规EPS助力控制难以随路面附着系数的变化提供合理的助力力矩的问题，提出了一种带有调节因子的助力控制。该方法通过调节因子在线调节车速感应系数，使EPS的助力特性随路面附着系数的变化而变化，从而增强EPS助力控制的自适能力。Matlab/simulink仿真研究表明，该方法能够随路面附着系数变化合理有效地调节助力力矩。

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 regula-ting factor to achieve that assist characteristic changes with the changes of road adhesion coeffi-cient.Furthermore,it can enhance the self-adaptive ability of EPS.It is approved that the assis-tant torque could be adjusted reasonably and effectively by the regulating factor,based on the simulation.
