ACTIVE STEERING CONTROL APPARATUS FOR RAILWAY VEHICLES AND THE METHOD OF THE SAME

摘要

PURPOSE: Active steering control apparatus and method for a railroad vehicle are provided to reduce the abrasion of wheel and rail by decreasing the attack angle between a curved section and the wheel and axle. CONSTITUTION: An active steering control apparatus for a railroad vehicle comprises a measuring unit(200), an estimating unit(300), a calculating unit(400), a control unit(500) and an actuator(600). The measuring unit measures traveling data of the railroad vehicle during running. The estimating unit estimates the curvature radius of a curved track is estimated using the measured data. The calculating unit sets the target value of the steering angle of wheel and axle using the estimated curvature radius. The control unit compares the target value with the real value of the steering angle of wheel and axle to generate a steering control signal for the wheel and axle. The actuator steers the wheel and axle with the steering signal of the control unit.
