Abstract
Controlling the movement of elevator cars () within a single hoistway () prevents the cars from becoming too close while servicing assigned stops. Example control techniques include controlling door operation of at least one of the elevator cars () to effectively slow down a follower car or speed up a leader car for increasing a distance between the cars in an area within the hoistway () where the cars would otherwise be too close to each other.
