Abstract
A command elevator speed generator for an elevator car which includes a counter for counting pulses corresponding to a distance of movement of an elevator car, a position sensor on the car for delivering a positional signal upon the car reaching a predetermined distance short of a calling or a called floor and a resetting circuit which is responsive to the positional signal for clearing the counter. An electronic computer then subtracts the succeeding count from a predetermined distance stored in it to calculate a residual distance to the floor for each of its calculating periods. A command deceleration signal is then read out from the computer to decelerate the car.
