  • Publication number: 20130320153
    Abstract: Disclosed is a travel velocity compensation apparatus for railway vehicles and a method thereof for compensating a travel velocity when there is generated a slide between a wheel and a railway, the apparatus including a velocity measurement unit measuring a travel velocity of a railway vehicle, a velocity estimation unit estimating the travel velocity using travel information of railway vehicle and rail information received from at least one sensor, a detection unit generating wheel slide information by determining whether wheels of the railway vehicle slide, using the travel velocity of the railway vehicle measured by the velocity measurement unit and the travel velocity estimated by the velocity estimation unit, and a selection unit selecting, as a travel velocity, any one of the travel velocity measured by the velocity measurement unit using the wheel slide information generated by the detection unit and the travel velocity estimated by the velocity estimation unit.

  • Publication number: 20130096741
    Abstract: An apparatus and method for controlling train speed are disclosed, the method including receiving an operation data, estimating a future train speed subsequent to a predetermined time of the train, using the operation data and dynamics model of a train, calculating a TTSLC {Time-To-Speed-Limit Crossing, a time when the train exceeds an ATP (Automatic Train Protection) speed limit}, and outputting a deceleration command by determining an additional braking force, in a case the TTSLC is smaller than a predetermined threshold.
