Abstract

An exemplary method of controlling elevator car position includes determining that an elevator car required re-leveling. Elevator car dynamics information associated with a current position of the elevator car is determined. A gain for controlling operation of a motor responsible for moving the elevator car for the re-leveling is adjusted based on the determined elevator car dynamics information.
