Research on Road Feeling Control Strategy of Steer-by-Wire 2007-01-3652

A steer-by-wire system has many benefits over conventional steering system for no mechanical link existing between the steering wheel and the road wheels. Road feeling has been being one of the most important vehicle characteristics reflecting vehicle directional control and stability. Besides the steering angle, road wheels reactive torque and vehicle dynamical behavior are considered in this paper. A control strategy with road wheels force feedback and steering wheel angle feedback was developed. The vehicle dynamic states are taken into account for road feeling simulation. Simulation shows that the control strategy achieves desired road feeling, and the second control strategy can improve the road feeling dynamically.
