Abstract
A group control for an elevator system assigns immediately destination calls which were entered at a floor lying behind the car in the direction of travel of the car and for a floor which lies ahead of the car. The group control includes a call memory having a first register for storing the calls of like direction of travel entered ahead of the car, a second register for storing the calls of opposite direction of travel and a third register for storing the calls of like direction of travel entered behind the car. A control circuit is activated each time a call is entered such that a call of the same direction of travel is written, according to its position with respect to the car, into the first or third register. The allocated calls of the third register are transferred into the second register on the first change in direction of travel of the car and into the first register on the second change in direction of travel so that they can be detected by a selector addressing the call memory.
