Modified Slowdown and Braking of an Elevator Car Abstract In elevator systems where the stop and/or slowdown operations are preset for maximum car velocity the stopping and/or slowdown operations are delayed in proportion to the variation from maximum car velocity in order to compensate for the shorter stopping distance required when the car is moving slower than that maximum velocity. Motor speed is sensed within a revolution to provide a signal which manifests the motor speed. This signal is referenced to a second signal which reflects the motor speed for maximum car velocity. The differ- ence between the two signals is a third signal which is used to control delay circuits which delay transmission of stop and/or slowdown signals to the brake and motor in a prescribed relationship to the magnitude of the difference between the two signals.
