Elevator car dispatching including passenger destination information and a fuzzy logic algorithm
First Claim
Patent Images
1. A method of controlling an elevator system, comprising:
- assigning an elevator car to respond to a passenger request that indicates an intended destination before the passenger enters an elevator car based upon the intended destination and a fuzzy logic car assignment algorithm; and
preferring to assign an elevator car that is already assigned to carry at least one other passenger from a source landing of the passenger request to the intended destination over at least one other elevator car that is traveling to the source landing without at least one other passenger assigned to board the other elevator car.

Abstract
An elevator system includes a controller that uses one of a plurality of fuzzy logic algorithms for assigning an elevator car to service a passenger request. One example uses a passenger'"'"'s desired destination as indicated by the passenger service request prior to the passenger entering an elevator car. One example includes multiple fuzzy logic algorithms, each corresponding to a particular relationship between an elevator car'"'"'s current assignments, a passenger'"'"'s desired destination, a source landing of the passenger'"'"'s request, or a combination of them.

10. A method of controlling an elevator system, comprising:
-
determining whether an elevator car has enough capacity to respond to a passenger request that indicates an intended destination before the passenger enters an elevator car based upon the intended destination and a destination of any other passenger assigned to the elevator car or currently on the elevator car; and determining a capacity of the elevator car to accommodate the passenger based upon a number of passengers currently on the elevator car, a number of passengers expected to leave the elevator car when or before the elevator car reaches a source landing of the passenger request and a number of passengers expected to board the elevator car when or before the elevator car reaches the source landing. - View Dependent Claims (11, 12, 13, 14)

15. An elevator system, comprising:
-
a plurality of elevator cars; and a controller that assigns one of the elevator cars to respond to a passenger request that indicates an intended destination before the passenger enters an elevator car based upon the intended destination and a fuzzy logic car assignment algorithm, wherein the controller determines whether a candidate elevator car will have capacity to receive the passenger for responding to the passenger request, wherein the controller determines a capacity of the candidate elevator car to accommodate the passenger based upon a number of passengers currently on the candidate elevator car, a number of passengers expected to leave the candidate elevator car when or before the candidate elevator car reaches a source landing of the passenger request and a number of passengers expected to board the candidate elevator car when or before the candidate elevator car reaches the source landing. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A method of controlling an elevator system, comprising:
-
assigning an elevator car to respond to a passenger request that indicates an intended destination before the passenger enters an elevator car based upon the intended destination and a fuzzy logic car assignment algorithm; and determining whether a candidate elevator car is assigned to travel to the intended destination or a source landing of the passenger request from which the passenger will board an elevator to be carried to the intended destination and using a no coincident call fuzzy logic algorithm when the candidate elevator car is not assigned to travel to the intended destination or the source landing.

23. A method of controlling an elevator system, comprising:
-
assigning an elevator car to respond to a passenger request tat indicates an intended destination before the passenger enters an elevator car based upon the intended destination and a fuzzy logic car assignment algorithm; determining whether a candidate elevator car will have capacity to accommodate the passenger for responding to the passenger request; and determining a capacity of the candidate elevator car to accommodate the passenger based upon a number of passengers currently on the candidate elevator car, a number of passengers expected to leave the candidate elevator car when or before the candidate elevator car reaches a source landing of the passenger request and a number of passengers expected to board the candidate elevator car when or before the candidate elevator car reaches the source landing.

24. An elevator system, comprising:
-
a plurality of elevator cars; and a controller that assigns one of the elevator cars to respond to a passenger request that indicates an intended destination before the passenger enters an elevator car based upon the intended destination and a fuzzy logic car assignment algorithm, wherein the controller determines whether a candidate elevator car is assigned to travel to the intended destination or a source landing of the passenger request from which the passenger will board an elevator to be carried to the intended destination and the controller uses a no coincident call fuzzy logic algorithm when the candidate elevator car is not assigned to travel to the intended destination or the source landing.

25. An elevator system, comprising:
-
a plurality of elevator cars; and a controller that assigns one of the elevator cars to respond to a passenger request that indicates an intended destination before the passenger enters an elevator car based upon the intended destination and a fuzzy logic car assignment algorithm, wherein the controller prefers to assign an elevator car that is already assigned to carry at least one other passenger from a source landing of the passenger request to the intended destination over another elevator car that is traveling to the source landing as a destination for at least one other passenger.
