Abstract:
1. A method for assigning a new hall call to one of a plurality of elevator cars in an elevator system comprising the steps of: (a) providing a controller, the controller configure to control the elevator system; (b) receiving a hall call signal, the hall call signal originating at an elevator landing; (c) transmitting the hall call to the controller; (d) programming the controller with an estimated wait time (EWT) threshold, wherein the EWT threshold is a time value above which a passenger is likely to become impatient waiting for one of the plurality of elevator cars to arrive; (e) programming the controller with an estimated travel time (ETT) threshold, wherein the ETT threshold is a time value above which the passenger is likely to become impatient waiting for their elevator car to arrive at its destination; (f) calculating an estimated wait time (EWT) for each of the plurality of elevator cars; (g) calculating an estimated travel time (ETT) for each of the plurality of elevator cars; (h) determining whether the EWT for each of the plurality of elevator cars is below the EWT threshold; (i) determining whether the ETT for each of the plurality of elevator cars is below the ETT threshold; and (j) assigning one of the plurality of elevator cars to the hall call by factoring in whether the EWT and ETT for each one of the plurality of elevator cars are below the EWT threshold and the ETT threshold.
