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.

A system for releveling an elevator car floor with a landing floor includes a load weight sensor to sense a load weight of an elevator car at a landing floor, and a releveling controller operably connected to the load weight sensor to calculate a corrective velocity for the elevator car based on the load weight and estimates of the effective stiffnesses at the landing floor. A machine is operably connected to the releveling controller with both feedback and feedforward control and the elevator car to apply the corrective velocity to the elevator car thereby reducing a mismatch between the elevator car and the landing floor.

A method of operating an elevator, the elevator having an elevator car, a motor, a controller and a counterweight (CW), the method including, for ascending of the elevator car when loaded with passengers, providing a car occupancy limiter (COL) and activating the COL by the controller for ensuring that the loaded car weighs less than the CW and controlling by the controller of the motor to not use motor rotational power; and for descending of the elevator car when loaded with passengers, where the loaded car weighs more than the CW, controlling by the controller of the motor to not use motor rotational power.

According to an aspect, there is provided an elevator parking brake comprising brake pads configured to provide a braking force against a guide rail in a loading and unloading situation of an elevator car; and at least one sensor. The elevator parking brake is configured to allow a predetermined amount of movement within the elevator parking brake in the loading and unloading situation of the elevator car, and the at least one sensor is configured to provide at least one indication associated with the movement within the elevator parking brake in the loading and unloading situation of the elevator car.

A method for dispatching an elevator car that includes determining the elevator car is located at a first location of a plurality of locations, and a predefined positional count corresponds to each of the plurality of locations. The method includes determining a positional count of the elevator car at the first location, and determining a load of the elevator car at the first location based on a difference between the positional count and the predefined positional count corresponding to the first location. The method includes controlling an operation of the elevator car based on the load of the elevator car at the first location.
