ABSTRACT:
An energy storage wheel spin propulsion control system for detecting and correcting a spinning wheel situation so that the maximum available adhesion is utilized to the fullest extent in accelerating a railway vehicle while at the same time maximizing the use of the available processing time to permit an appropriate amount of time for diagnostic purposes. The primary data used to form the logic inputs is derived from the axle rate signals which are fed to spin energy storage value threshold and difference comparison sensors. The spin energy storage value and difference comparison sensors supply logical inputs in spin energy threshold, dissipation threshold and optimization threshold sensors and spin rate difference sum sensor, respectively, which, in turn, supply logic inputs to spin enable timer and spin enable sensors and a spin control logic output sensor. A slip-spin output determination sensor receives logic signals from a power-brake signal circuit and command signal from the spin control logic outer sensor and a slip interface circuit to cause the production of a full requested, reduce and/or hold tractive effort command.
