DISTURBANCE REDUCTION DEVICE OF AN INDEPENDENT STEER-BY-WIRE SYSTEM FOR IMPROVING CONTROL STABILITY BY REDUCING THE INFLUENCE OF DISTURBANCE ENTERED A DRIVING MOTOR THROUGH A WHEEL

摘要

PURPOSE: A disturbance reduction device of an independent steer-by-wire system is provided to improve the fuel consumption of a vehicle with a decrease in power consumption of a driving motor by reducing the influence of disturbance entered a driving motor through a wheel, and to improve the control stability of a vehicle by cutting off the inflow of disturbance to a driving motor if disturbance is excessive.;CONSTITUTION: A disturbance reduction device of an independent steer-by-wire system comprises a rack bar(18) connected to a wheel to steer a wheel, a ball screw(19) coupled to the rack bar to transfer rotary force and connected to a driving motor(16) by a belt(20), and an electronic brake(17) connected to one end of the rack bar to apply damping force and equipped with a cylinder(17b) filled with a magneto-rheological fluid(17a), a piston(17c) installed to be movable forward and backward in the cylinder and a piston rod(17d) connected to the piston and the rack bar.;COPYRIGHT KIPO 2010
