Active-steering control system based on human hand impedance properties

This paper proposes an active-steering control method that uses human hand impedance properties. In this method, the dynamic properties of a steering device manipulated by the upper limbs are automatically regulated according to the damping coefficient of the human-steering system. Human hand impedance in steering operations is measured and modeled depending on the steering angle and torque for use in the proposed control structure. The effectiveness of the proposed method was demonstrated by performing an emergency avoidance task using a stationary driving simulator.
