Title: Wheel spin control system
Inventor: WOOD JAMES A
IPC: B61C15/14
Filed: 1990-01-31
Abstract: The control system detects and corrects wheel spin so that the maximum available adhesionis used to the fullest extent in accelerating a railway vehicle while at the same time maximising the use of the available processing time to permit an appropriate amount of time for diagnostic pruposes. In the system the primary data used to form the logic inputs is derived from the axle rate signals (1AR, OAR). These signals are fed to spin energy storage value sensors (SESVALO, SESVALI), summers (SESSUMO, SESSUMI), threshold gates (SPTM 1,2,3) and a comparator (SRDCP). The summers supply logical inputs to a spin energy threshold (SETHR), a dissipation threashold (SEDTH) and an optimazation threshold (SEOTH) sensor. The comparator (SRDCP) supplies an input to a spin rate difference sum sensor (SRDFO). These in turn, supply logic inputs to a spin enable timer (SET) and a spin enable sensor (SPE) and a spin control logic output sensor (SPCLO). A slip-spin output determination sensor (SSOD) receives logic signals from a power-brake signal circuit (PBS) and command signals from the spin control logic output sensor (SPCLO) and a slip interface circuit (PAST PTC1). The sensor causes the production of a full, reduce and/or hold tractive effort command (40).
