STEERING TORQUE CONTROL USING VARIABLE IMPEDANCE MODELS FOR A STEER-BY-WIRE SYSTEM
D. S. CHEON, K. H. NAM
Yeungnam University
ABSTRACT
ering feel based on impedance control. Therefore, the model of rack and pinion is not considered in this work. In most power steering systems, a torque sensor is used to set impedance effect on driver’s steering feel. In this paper, we proposed a novel steering control method without using any torque sensors. The effectiveness of a proposed method is confirmed from experimental results.
Key Words: Sensor-less force control, Disturbance observer, Steer-by-wire, Impedance control
