  • Traction vehicle/wheel slip and slide control
    Patent number: 6499815
    Abstract: The system and method maximize available rail adhesion between the rails of a track and the wheels of a rail vehicle so that the vehicle is better able to accelerate up to operating speed and to decelerate to a stop condition under poor rail conditions. The system implements a control logic function which relies on a measured variable that is different than the controlled error signal utilized to affect control of the vehicle. The control system is enabled based on creep speed while the parameter used to effect control is wheel acceleration.
