System and method for dynamically modifying a capacity limit of an elevator car

An elevator system comprising:

• a controller;
• an elevator car operationally connected to the controller;
• a first sensor configured to provide first sensor data to the controller, wherein the controller is configured to identify a capacity parameter of the elevator car, wherein the capacity parameter includes one or more of:
• loaded weight;
• volume of available space;
• or volume of occupied space;
• a second sensor configured to provide second sensor data to the controller, wherein the controller is configured to determine that passengers remain outside the elevator car in response to the elevator car being stopped at a landing and its elevator doors are open;
• and
• wherein from the first sensor data and the second sensor data, the controller is configured to determine a reduced capacity limit for the elevator car as a function of the capacity parameter,
• wherein:
• when determining the reduced capacity limit, controller is configured for:
• accumulating data related to passengers entering the elevator car in response to hall calls while the elevator car is near its design capacity limit or previously determined reduced capacity limit;
• setting the reduced capacity limit to correlate with a predetermined boarding probability and setting a tolerance range around the reduced capacity limit;
• determining whether passengers enter the elevator car in response to hall calls;
• upon determining that passengers enter the elevator in response to hall calls, increasing the reduced capacity limit by half the tolerance range to an upper capacity tolerance, otherwise decreasing the reduced capacity limit by half the tolerance range to a lower capacity tolerance;
• determining whether the boarding probability is within acceptable limits over time;
• and
• upon determining that the boarding probability is outside of acceptable limits over time, modifying one or both of the tolerance range and the reduced capacity limit.
