Abstract
An elevator system includes an elevator car, a pressure sensor, and a controller. The car is adapted to move vertically within a hoistway and defines a passenger compartment adapted to be occupied by at least one passenger. The sensor is configured to measure air pressure in the passenger compartment. The controller is configured to control travel of the elevator car, receive a plurality of pressure signals from the sensor indicative of changing air pressure in the passenger compartment over a prescribed time period, and execute a preprogrammed application configured to apply a current car velocity and the changing air pressure to a preprogrammed ear pressure table. Upon application, the controller outputs a command to reduce the current car velocity if application of the preprogrammed ear pressure table determines a differential ear pressure would otherwise exceed a preprogrammed threshold.
