ABSTRACT:
An electronic landing device for controlling the movement of an elevator car during the final several inches of travel approaching a floor. The device provides a smooth transition from run (deceleration) mode to landing mode within a wide range of speeds at the transfer point. A digital computation is performed on a speed signal generated at the transfer point, to provide optimum time-to-landing and decelaration profile during the landing mode.
