VEHICLE SPEED/DISTANCE POFILE CONTROLLER

摘要

A vehicle speed control arrangement with particular but not exclusive utility for bringing railway vehicles to a stop, e.g. at a station platform. A speed/distance retardation profile is contained in vehicle-mounted "look-up" read-only memories which are initiated into controlling the vehicle brakes by passing a fixed trackside marker. Profile deviation limits are initiated or inhibited to idealise the stopping procedure in respect of limitation of the number of braking level changes, minimising braking time to save total journey time, maximising passenger comfort, and repeatable accuracy of stopping.
