Abstract

Three kinds of power curve are analyzed aimed at the sense of strength and steering portability. Thus, we put forward a new design principle based on the existing research. The assist characteristic range is divided into four kinds according to the vehicle speed and steering wheel torque. The simulation model of Electric Power Steering system is established in MATLAB/Simulink. The simulation results show that the new type of power assisted characteristic curve can better meet the steering portability during the low speed and good road feel at the high speed. Besides, the new type power assisted characteristic curve can avoid the frequent starting of motor and can protect the motor.
