The present invention relates to a track curvature estimation system and a track curvature estimation method for active steering control of a railway vehicle, the track curvature estimation system for active steering control of a railway vehicle being attached to front and rear carriages of two vehicles, measuring the magnitude of displacement between the front and rear carriages, and measuring the running speed of the preceding vehicle, a relative angle in the front-rear direction formed by the front carriage and the rear carriage of the preceding vehicle is estimated from the measured relative displacement, the estimated value of the magnitude R of the radius of curvature of the track is calculated by the numerical expression # imgabs0 #, and the travel distance of the preceding vehicle is calculated on the basis of the speed data measured by the speed sensor. Thereby, upon specifying the position of the following vehicle of the vehicle length, the track curvature radius estimate data is mapped to the position of the following vehicle and transmitted to the active steering control unit of the following vehicle.
本发明涉及用于铁路车辆的主动转向控制的轨道曲率估计系统及轨道曲率估计方法,所述用于铁路车辆的主动转向控制的轨道曲率估计系统安装于两个车辆的前后方台车,测定前后方台车之间的位移大小,并测定先头车辆的运行速度,从所测定的相对位移中估计先头车辆的前方台车及后方台车所形成的前后方向的相对角度,通过数式#imgabs0#来运算轨道曲率半径的大小R的估计值,基于速度传感器所测定的速度数据来运算先头车辆的行驶距离,从而在对车辆长度的后行车辆的位置进行特定后,向后行车辆位置映射轨道曲率半径估计值数据,并向后行车辆的主动转向控制单元进行传输。
