Electric power steering (EPS) system can not only provide steering power and lighten the burden of the driver's manipulation, but also improve vehicle steering performance and driving comfort, thus improving vehicle active safety. However, in the process of EPS system development, the determination of EPS assistance characteristics curve mainly depends on the driver's subjective evaluation, which needs more time in real vehicle debugging and calibration. In this paper, a novel design method of EPS assistance characteristics curve is proposed. Firstly, the relationship between EPS assistance torque and the driver's steering torque is determined based on the steering wheel torque characteristics of passenger cars; Secondly, a speed interval division method of EPS assistance map is put forward based on the static lateral acceleration gain; Finally, a three-dimensional map that electric control unit demands is drawn and its effect is verified through the real vehicle test.
