Abstract:
A method for dynamically adjusting a levelling speed limit of an elevator car during a levelling operation includes obtaining an indication that the elevator car is detected to arrive to a zone; obtaining at least one value indicating the speed of the elevator car, in response to detecting that the elevator car arrives to the zone; and dynamically adjusting the levelling speed limit of the elevator car based on the speed of the elevator car. An elevator control unit and a system are provided to perform at least partly the method.
