Abstract

The dynamics model of steering wheel module and aligning torque model of the mechanical steering system were established. According to the shortcomings of the fixed steering ratio in traditional steering system, a control strategy of road feeling was designed from the two aspects: control force of the driver, turning angle of the steering wheel. Fuzzy-PID controller was designed to real-timely control the road feeling simulating motor and achieve the self-aligning of the steering wheel. The simulation results showed the road feeling control strategy could make good use of steer-by-wire and satisfy the steering convenience and sensitivity at low speed and the steering clear and stability at high speed.
