Patent ID: 7810889

Claim:
A brake system for a railway vehicle, which vehicle comprises a plurality of bogies, each of which bogies has at least one axle, wherein at least some of said axles are provided with axle speed sensors adapted to measure the speed of rotation of the respective axle, the output of the axle speed sensor being fed to a data processor, wherein the data processor is provided with local intelligence so as to permit individual control of brake pressure on each axle or bogie or car, the data processor being adapted to communicate with a brake control unit via a databus, the sensor outputs being processed so that the data can be communicated between the data processor and further data processors, which further data processors are adapted to process sensor outputs on further axles or bogies, wherein the data processor is provided with a wheel slide control unit, which data processor and wheel slide control unit cooperate to function as a bogie-specific brake control unit, which, in use, controls the brake pressure independently of the main brake control unit, wherein the wheel slide control unit is connected to the databus so that the wheel slide control unit communicates with other bogie-specific brake control units associated with other bogies on the vehicle.
