Abstract
A method can be used to position a car door and a landing-stop door in a synchronized manner at a landing stop in an elevator shaft of an elevator system. The car door may be configured as a guide door, and the landing-stop door may be configured as a follower door. The method may involve bringing an elevator car close to the landing stop, upon entry of the car door into an unlock zone sensing a presence signal of the follower door by way of a presence sensor of the guide door, actuating the guide-door drive by way of the guide controller and executing an opening movement of the guide door, providing movement information of the guide door, and actuating the follower-door drive of the follower door.
