The elevator system includes a plurality of elevators. The dynamic car assignment method includes an assignment, by the elevator system, of a first elevator car of the plurality of elevators to pick up a passenger in response to an elevator call. The elevator system then detects that the first elevator car is fully occupied prior to the first elevator car arriving to pick up the passenger. Further, the elevator system dynamically assigns a second elevator car of the plurality of elevator cars to pick up the passenger in response to the elevator call and in response to detecting that the first elevator car is fully occupied. ## Claims ### Claim 1 A dynamic car assignment method implemented by an elevator system comprising a plurality of elevators, the dynamic car assignment method comprising: assigning, by the elevator system, a first elevator car of the plurality of elevators to pick up a passenger in response to an elevator call, wherein the elevator call is a hall call received from a lobby, the hall call being initiated by the passenger waiting in the lobby for one of the plurality of elevators, none of the plurality of the elevators being located at a same floor as the lobby at the time of the hall call; wherein the elevator system utilizes a sensor to detect an occupancy of the first elevator car to determine whether the occupancy is less than a total occupancy limit for the first elevator car, wherein the elevator system assigns the first elevator car when the occupancy of the first elevator car is less than the total occupancy limit for the first elevator car; detecting, by the elevator system, that the first elevator car is fully occupied prior to the first elevator car arriving to pick up the passenger; and dynamically assigning, by the elevator system, a second elevator car of the plurality of elevator cars to pick up the passenger in response to the elevator call and in response to detecting that the first elevator car is fully occupied. ### Claim 2 (depends on 1) The dynamic car assignment method of claim 1, wherein the elevator system detects that the first elevator car is fully occupied by detecting that a number of one or more other passengers within the first elevator car prior is equal to a total occupancy limit for the first elevator car prior to the first elevator car arriving to pick up the passenger. ### Claim 3 (depends on 1) The dynamic car assignment method of claim 1, wherein the elevator system utilizes a sensor to detect an occupancy of the second elevator car to determine whether the occupancy is less than a total occupancy limit for the second elevator car prior to assigning the second elevator car, and wherein the elevator system assigns the second elevator car when the occupancy of the second elevator car is less than the total occupancy limit for the second elevator car. ### Claim 4 (depends on 1) The dynamic car assignment method of claim 1, wherein the elevator system is in communication with a mobile call of the passenger, the elevator call is received from a mobile device, the mobile call being initiated by the passenger requiring one of the plurality of elevators. ### Claim 5 (depends on 1) The dynamic car assignment method of claim 1, wherein the elevator system is in communication with a mobile call of the passenger, the elevator system providing elevator car assignments to a mobile device to cause the mobile device to displaying a prompt indicating the assignment of the first elevator car and to update the prompt to the assignment of the second elevator car. ### Claim 6 An elevator system comprising a plurality of elevators and a processor executing dynamic car assignment software to cause the elevator system to: assign a first elevator car of the plurality of elevators to pick up a passenger in response to an elevator call, wherein the elevator call is a hall call received from a lobby, the hall call being initiated by the passenger waiting in the lobby for one of the plurality of elevators, none of the plurality of the elevators being located at a same floor as the lobby at the time of the hall call; wherein the elevator system utilizes a sensor to detect an occupancy of the first elevator car to determine whether the occupancy is less than a total occupancy limit for the first elevator car, wherein the elevator system assigns the first elevator car when the occupancy of the first elevator car is less than the total occupancy limit for the first elevator car; detect that the first elevator car is fully occupied prior to the first elevator car arriving to pick up the passenger; and dynamically assign a second elevator car of the plurality of elevator cars to pick up the passenger in response to the elevator call and in response to detecting that the first elevator car is fully occupied. ### Claim 7 (depends on 6) The elevator system of claim 6, wherein the elevator system detects that the first elevator car is fully occupied by detecting that a number of one or more other passengers within the first elevator car prior is equal to a total occupancy limit for the first elevator car prior to the first elevator car arriving to pick up the passenger. ### Claim 8 (depends on 6) The elevator system of claim 6, wherein the elevator system utilizes a sensor to detect an occupancy of the second elevator car to determine whether the occupancy is less than a total occupancy limit for the second elevator car prior to assigning the second elevator car, and wherein the elevator system assigns the second elevator car when the occupancy of the second elevator car is less than the total occupancy limit for the second elevator car. ### Claim 9 (depends on 6) The elevator system of claim 6, wherein the elevator system is in communication with a mobile call of the passenger, the elevator call is received from a mobile device, the mobile call being initiated by the passenger requiring one of the plurality of elevators. ### Claim 10 (depends on 6) The elevator system of claim 6, wherein the elevator system is in communication with a mobile call of the passenger, the elevator system providing elevator car assignments to a mobile device to cause the mobile device to displaying a prompt indicating the assignment of the first elevator car and to update the prompt to the assignment of the second elevator car. ### Claim 11 A computer program product comprising a non-transitory computer readable medium storing processor executable instructions for dynamic car assignment, the processor executable instructions being executed by a processor of an elevator system comprising a plurality of elevators to cause the elevator system to: assign a first elevator car of the plurality of elevators to pick up a passenger in response to an elevator call, wherein the elevator call is a hall call received from a lobby, the hall call being initiated by the passenger waiting in the lobby for one of the plurality of elevators, none of the plurality of the elevators being located at a same floor as the lobby at the time of the hall call; wherein the elevator system utilizes a sensor to detect an occupancy of the first elevator car to determine whether the occupancy is less than a total occupancy limit for the first elevator car, wherein the elevator system assigns the first elevator car when the occupancy of the first elevator car is less than the total occupancy limit for the first elevator car; detect that the first elevator car is fully occupied prior to the first elevator car arriving to pick up the passenger; and dynamically assign a second elevator car of the plurality of elevator cars to pick up the passenger in response to the elevator call and in response to detecting that the first elevator car is fully occupied. ### Claim 12 (depends on 11) The computer program product of claim 11, wherein the elevator system detects that the first elevator car is fully occupied by detecting that a number of one or more other passengers within the first elevator car prior is equal to a total occupancy limit for the first elevator car prior to the first elevator car arriving to pick up the passenger. ### Claim 13 (depends on 11) The computer program product of claim 11, wherein the elevator system utilizes a sensor to detect an occupancy of the second elevator car to determine whether the occupancy is less than a total occupancy limit for the second elevator car prior to assigning the second elevator car, and wherein the elevator system assigns the second elevator car when the occupancy of the second elevator car is less than the total occupancy limit for the second elevator car. ### Claim 14 (depends on 11) The computer program product of claim 11, wherein the elevator system is in communication with a mobile call of the passenger, the elevator call is received from a mobile device, the mobile call being initiated by the passenger requiring one of the plurality of elevators.
