Abstract: A method for operating an elevator system having a shaft system and elevator cars that are moved separately between floors in a circulation operation may involve moving the elevator cars upward in a first shaft and moving the elevator cars downward in a second shaft. A number of shaft positions that can be respectively adopted by the elevator cars and that correspond to the number of elevator cars is defined, and synchronization of movement of the elevator cars may be carried out with respect to these defined shaft positions. Further, each of the elevator cars may be moved according to a travel curve. To synchronize the movement of the elevator cars the travel curve for each elevator car may be adapted to account for positions of the elevator cars in the same shaft.

Abstract: A method for operating an elevator system, which may include at least two cars that can move independently of one another within a common elevator shaft, may involve determining with an elevator controller to cause a first car of the at least two cars to perform a transportation process from a start stopping point to a destination stopping point. The elevator controller may determine a starting time and travel parameters according to which the first car carries out the transportation process from the start stopping point to the destination stopping point. The starting time and the travel parameters may be determined by taking into account state parameters of a second car of the at least two cars.

Abstract: A method for operating an elevator system can be used with elevator systems that include at least two cars and at least two vertically extending elevator shafts where the at least two cars can be moved between the at least two elevator shafts. In a first operating mode transportation operations are performed by the at least two cars in the at least two elevator shafts. In a second operating mode a location of at least one of the at least two cars is restricted to at least one region of at least one of the at least two elevator shafts. In the second operating mode, the at least one of the at least two cars is not available for transportation operations in remaining regions of the at least two elevator shafts.

Abstract: The present disclosure relates to a method for operating an elevator system, which is embodied as shaft-changing multi-car system. A number of cars is assigned to at least three elevator shafts. The cars can be moved in upwards direction and downwards direction inside the individual elevator shafts, as well as between the individual elevator shafts. A successive reversal of the travel directions of the respective cars occurs hereby.

Abstract: Lift systems may include a first shaft unit and a second shaft unit, each of which may include a number of lift shafts. One or more single-car systems and/or multi-car systems may be disposed in the first shaft unit, whereas one or more shaft-changing multi-car systems may be disposed in the second shaft unit. A transporting operation may be carried out from an initial floor to a destination floor wherein a control unit determines whether to utilize one or more cars from the single car systems, the multi-car systems, the shaft-changing multi-car systems, or some combination thereof depending on factors such as the destination floors of the passengers, traffic density, energy demand, and/or availability of cars.

Abstract: The invention relates to a method for the processing of call inputs of a user by an elevator controller of an elevator installation in which a user inputs either an external call and an internal call or a destination call into the elevator controller, wherein the elevator controller generates at least two sub-calls in reaction to the internal call or the destination call, wherein the sub-calls comprise at least one external call and/or at least one internal call whose destination floor is different from the destination floor of the internal call input by the user. The invention furthermore relates to a method in which an elevator controller generates a destination call or an internal call in reaction to an external call. The invention furthermore relates to corresponding elevator installations designed for carrying out these methods.

Abstract: A method for controlling a lift installation having a plurality of cabins that can each stop at a number of floors may involve assigning calls placed outside the cabins to the cabins by way of a lift controller based on at least one assignment criterion. The method may involve considering a current traffic situation of the lift installation during the assignment. The method may further involve generating and considering a forecast of a future traffic situation of the lift installation during the assignment. The forecast may account for personal information of at least one of a person who is in a predetermined environment of the lift installation, a person who is in a section of the lift installation, a person who enters a predetermined environment of the lift installation, or a person who leaves a predetermined environment of the lift installation.

Abstract: A control system for an elevator system may comprise elevator cars and an elevator control for assigning elevator cars to destination calls. In a first mode of operation, the elevator control may be adapted to determine and assign an elevator car to transport a passenger based on at least one elevator car determination criterion. The elevator control may wait to provide information identifying the elevator car assigned to the passenger until the assigned elevator car approaches or arrives at a floor on which the passenger is located. Waiting to provide such information permits the elevator control to modify which elevator car ultimately transports the passenger based on intervening factors such as a door being held on an elevator car that was initially assigned to transport the passenger. In a second mode of operation, the passenger may be provided with the information that identifies the assigned elevator car immediately after the destination call is placed.
