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.
