STEER-BY-WIRE STEERING CONTROL SYSTEM USING AN ELECTRIC CURRENT DIRECT MEASUREMENT METHOD, FOR MAKING A DRIVER COMFORTABLE AND OFFERING THE DRIVING FEEL LIKE THE REAL TO A DRIVER BY DYNAMICALLY ANALYZING THE LATERAL FORCE APPLIED TO A VEHICLE WHEEL

摘要

PURPOSE: A steer-by-wire steering control system using an electric current direct measurement method is provided to control the driving feel according to the property of a driver, to offer the real driving feel to a driver, and to have simple structure.;CONSTITUTION: A steer-by-wire steering control system using an electric current direct measurement method comprises a first loop(10) and a second loop(20). The first loop traces the information like a steering angle of a hand wheel(11), a vehicle speed, a vehicle acceleration and so on which are input commands of a driver. The second loop transmits a force feedback(F) to a driver by directly measuring an inertial force applied to a road wheel(14) of a vehicle, damping, steering angle and so one as electric current signals.;COPYRIGHT KIPO 2010
