ABSTRACT:
A method and apparatus for controlling doors of an elevator includes a passenger sensor and load sensor. The passenger sensor detects the presence of passengers in a lobby, and the load sensor generates a load signal indicating only a load of the elevator. A processor then determines passenger movements between the lobby and the elevator, and passenger movements within the elevator based on the load signal. Next, an elevator door controller controls the elevator doors based on output from the processor and the passenger sensor.
