Claim One:
1. A brake HILS system for a railway vehicle, comprising: a user terminal that receives values relating to braking conditions of a railway vehicle through a user interface and monitors simulation results; a pneumatic brake that includes an electronic control unit, a brake operation unit, a wheelset, a brake caliper, and a wheel slide protection valve and produces pneumatic pressure and transmits a braking force to the wheelset in accordance with the braking conditions from the user terminal; a load cell that is disposed on a wheel or a disc and measures a braking force from the pneumatic pressure; a pressure sensor that measures pneumatic pressure and feeds back thereof; and a modeling unit that simulates the running and braking dynamic characteristics of a railway vehicle in real-time using mathematical models, wherein the modeling unit: simulates in real-time a wheel slide protection function by producing different adhesive forces for wheelsets by changing a friction coefficient between a wheel and a rail in the vehicle running simulation; feeds back to the electronic control unit at least one signal among four wheelset speeds, an emergency braking command, a brake mode signal, payload, and a brake command, corresponding to the simulation result for braking of the railway vehicle; includes at least one parameter among a braking command, an emergency instruction, payload, a track inclination, a track friction coefficient, an adhesive coefficient, information about variable vehicle weight; and simulates in real-time the braking dynamic characteristics of various railway vehicles by changing the parameters of railway vehicles.
