The present invention relates to an individual braking system for an independently rotating wheel type railroad vehicle, a railroad vehicle having the same, and a control method of an individual braking system for an independently rotating wheel type railroad vehicle, wherein the braking system reduces a lateral force, abrasion of a wheel, and noise by appropriately controlling a brake force depending on a railroad condition during running of a railroad vehicle. To this end, the individual braking system for an independently rotating wheel type railroad vehicle of the present invention comprises: a plurality of independently rotating wheels; a plurality of braking apparatuses installed on the plurality of independently rotating wheels, respectively; and a controller which executes a speed difference removal mode, removing a speed difference between the plurality of independently rotating wheels, or a speed difference generation mode, generating a speed difference between the plurality of independently rotating wheels, based on information on a radius of curvature.

    본 발명은 철도차량 주행 시 레일 상황에 따라 적절하게 제동력을 제어하여 횡압을 줄이고, 휠 마모와 소음을 감소시킬 수 있는 독립회전식 철도차량용 개별 제동시스템 및 이를 구비한 철도차량, 독립회전식 철도차량용 제동시스템의 제어방법에 관한 것이다. 이를 위한 본 발명의 독립회전식 철도차량용 개별 제동시스템은, 복수의 독립회전 휠; 상기 복수의 독립회전 휠에 각각 구비된 복수의 제동장치; 및 곡선반경 정보에 근거하여 상기 복수의 독립회전 휠의 속도차를 제거하는 속도차 제거모드 또는 상기 복수의 독립회전 휠의 속도차를 발생시키는 속도차 발생모드를 수행하는 제어기;를 포함하여 구성된다.
