The frequency response of steering effort torque changes according to the influence of vehicle dynamics. To help enhance feel, a new electronic power steering (EPS) control has been constructed. As the control can be achieved by the addition of a viscosity control with a filter to existing EPS systems, its structure is simple and easily installed. Actual vehicle tests have been performed to verify that the control is capable of enhancing convergence without adversely affecting response during steering.
