Abstract
Elevator control apparatus for monitoring the floor position of a car utilizing a switch on the car to sense floor indicator cams each spaced along the hoistway in regular spatial relation to an associated floor. The control apparatus includes means to register signals from the floor switch while knowing the simultaneous direction of car travel to thereby enable it to distinguish ascent to a higher floor and descent to a lower floor. The control apparatus also includes means to disregard false signals from the floor switch resulting from car bounce and mid-floor reversals of car direction.
