Disclosed is an apparatus and method for estimating railway vehicle masses, the method comprising checking if a train has entered an initial acceleration section and a straight section, receiving a speed of the train, each acceleration of the plurality of railway vehicles and each traction of the plurality of railway vehicles, dynamically modeling the train, and estimating masses of the plurality of railway vehicles and rail gradient.

Apparatus and method for estimating railway vehicle masses

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.

Travel velocity compensation apparatus and method for railway vehicles

Disclosed is a load compensating device in railway vehicles, the device including a pressure sensor detecting an air spring pressure in response to loads of the vehicles, an estimation unit outputting an estimated railway vehicle load by estimating each load of a plurality of railway vehicles, and a detection unit outputting a railway vehicle load by detection of fault in the pressure sensor.
