Abstract

See full text

A group control selects the cars of an elevator group for boarding passengers such that the passenger arrive at the shaft door of the selected elevator earlier than the selected car whereby unnecessarily long stops are avoided. A memory for the storage of times needed by a passenger for traversing the paths between the respectively actuated call registering and indicating device and the shaft doors of the elevator is provided for each elevator. A comparator connected to the memory compares the passenger traverse time with the travelling time of the car to the call input floor. If the travelling time is less than the time needed by the passenger to move to the shaft door, a switching device connected to the output of the comparator becomes effective to exclude the elevator from the call allocation procedure.
