Abstract: PURPOSE: A method of estimating a radius of curvature for the curved section of a railway vehicle is provided to efficiently estimate a radius of curvature of the railway vehicle using the position data on a bogie. CONSTITUTION: A method of estimating a radius of curvature for the curved section of a railway vehicle is as follows. The relative angle and longitudinal displacement between a vehicle body and front/rear bogies when the railway vehicle runs on a curved section are measured using a displacement sensor(s10). The curvature radius in the curved section is estimated using the measured relative angle and displacement(s20). The estimated curvature radius is verified(s30).

Abstract: The present invention relates to an active steering control device and method for a railroad vehicle, and more specifically, to an active steering control device and method for a railroad vehicle, which can smoothly steer a moving railroad vehicle by estimating the radius of curvature of a curved line in real-time when the train moves on the curved line and controlling an optimal steering angle of the wheel and axle according to the estimated radius of curvature, and can remarkably reduce an angle of attack which exists between the curved line and the wheel and axle. The invention includes: a measurer that measures drive data of the moving railroad vehicle; an estimator that estimates the radius of curvature of the curved line on which the railroad vehicle is moving, by using the data measured in the measuring unit; a calculator that sets a target value of the steering angle of the wheel and axle of the moving railroad vehicle, by using the radius of curvature estimated in the estimator; a controller that generates a steering control signal on the wheel and axle by comparing an actual steering angle of the wheel and axle with the target value of the steering angle of the wheel and axle, which is set in the calculator; and an actuator that steers the wheel and axle using the steering signal of the controller.
