Title:
ACTIVE STEERING CONTROL DEVICE AND METHOD FOR RAILROAD VEHICLE
Document Type and Number:
WIPO Patent Application WO/2011/078461
Kind Code:
A1
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 running railroad vehicle by estimating the radius of curvature of a curved line in real time when the train runs on the curved line and controlling an optimal steering angle on 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 comprises: a measurer that measures drive data of the running railroad vehicle; an estimator that estimates the radius of curvature of the curved line on which the railroad vehicle is running, by using the data measured in the measuring unit; a calculator that sets a target value of the steering angle on the wheel and axle of the running 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 on the wheel and axle with the target value of the steering angle on the wheel and axle, which is set in the calculator; and an actuator that steers the wheel and axle by the steering signal of the controller.
