ABSTRACT:
A method of and an apparatus for controlling wheel slip in a railway vehicle brake system which includes: determining whether the axle rate is in the slippage range, and generating a first output logical signal indicative thereof; comparing the axle rate and the first output logical signal to determining an energy summation value indicative of the wheel/axle set's loss of energy due to braking wheel slippage, and generating an energy summation signal indicative thereof; determining an energy loss limit and generating an energy loss limit signal at which wheel slippage has little potential for self correction; comparing the energy summation signal and the energy loss limit signal to generate a second logical output signal indicative of whether the wheel/axis set is in a slip condition that needs correction; comparing the axle rate signal, the energy summation signal and the second logical output signal to generate a wheel slip intensity signal; converting the wheel slip intensity signal to a command signal; and utilizing the command signal in a force modulation interface to vary the rate of braking force reduction.
