  • Wheel slip correction method, system and apparatus
    Patent number: 4095147
    Abstract: The following specification described a method or system of correcting locomotive wheel slip in which each driven wheel provides a wheel velocity signal proportional to its angular velocity. This signal is compared in a wheel slip detection circuit for each wheel with a train speed signal to derive a signal corresponding to the difference in the event of wheel slip. This difference signal is differentiated to provide a signal corresponding to the acceleration and multiplied by a signal corresponding to the slipping wheel speed to provide a correction signal corresponding to the power lost in the slipping wheel.The wheel velocity signals are compared in a "less than" and a "greater than" circuit respectively to derive the train speed signal and the slipping wheel signal.
