Abstract: A system and method of measuring and diagnosing the ride quality of an elevator system, including (a) operating the mobile device to acquire ride quality data, (b) operating the mobile device to transmit ride quality data to an external computing device, (c) operating the external computing device to compare the acquired ride quality data to pre-determined system data to create performance data, (d) operating the external computing device to perform a ride quality diagnostics based at least in part on the performance data, and (e) operating the external computing device to transmit the ride quality diagnostics to the mobile device.

Abstract: Embodiments are directed to determining that an elevator car of an elevator system is approaching a landing, obtaining, by a controller, a value for at least one parameter associated with the elevator system based on the determination that the elevator car is approaching the landing, determining that the elevator car arrives at the landing within a threshold distance, determining, by the controller, when to engage in at least one of a brake cycling operation and a power cycling operation based on the value for the at least one parameter and based on determining that the elevator car arrives at the landing within the threshold distance, and initiating the at least one of a brake cycling operation and a power cycling operation at a time corresponding to the determination of when to engage in the at least one of a brake cycling operation and a power cycling operation.
