ABSTRACT:
A wheel slip control system employs a method of varying the detection and correction parameters it uses based on whether the wheel/axle combinations on a truck of a rail vehicle operate in the coupled or decoupled modes of operation. The control system executes programming code featuring detection and correction logic. The steps of the method include deriving both detection parameters optimized for each mode called coupled and decoupled detection parameters and correction parameters optimized for each mode called coupled and decoupled correction parameters. Another step involves monitoring the amount of dynamic braking applied to the wheel/axle combinations. Yet another step involves determining whether the amount of dynamic braking lies for a preset time period within a preset zone of operation for the dynamic braking of the wheel/axle combinations on the truck. The method provides the coupled detection parameters to the detection logic if the amount of dynamic braking lies within the preset zone for the preset time. Alternately, it provides the decoupled detection parameters to the detection logic if the amount of dynamic braking fails to lie within the preset zone for the preset time. The method provides the coupled correction parameters to the correction logic if the amount of dynamic braking lies within the preset zone for the preset time. Alternately, it provides the decoupled correction parameters to the correction logic only if the amount of dynamic braking fails to lie within the preset zone for the preset time when the wheel slip control system is inactive.
