Abstract: An elevator system control system (301) is provided and includes a sensor system (302) configured to sense elevator car conditions, a safety system signaling element (303) to generate a safety signal indicative of an incident and a control system (310) configured to react to the safety system signal. When the control system (310) receives the safety signal indicating that an incident has occurred that requires engagement of at least one of primary and secondary brakes, the control system (310) controls a deceleration rate during the incident by operating the primary brake, determining whether the deceleration rate is within a target range and adjusting the deceleration rate based on signals from the sensor system.

Abstract: An elevator system includes a first elevator car (28) constructed and arranged to move in a first lane (30, 32, 34) and a first propulsion system (40) constructed and arranged to propel the first elevator. An electronic processor of the elevator system is configured to selectively control power delivered to the first propulsion system (40). The electronic processor includes a software-based power estimator configured to receive a first weight signal and a nm trajectory signal for calculating a power estimate and comparing the power estimate to a maximum power allowance. The electronic processor is configured to output an automated command signal if the power estimate exceeds the maximum power allowance.
