Abstract
A method of controlling an elevator installation having an elevator car transporting passengers between floors of a building inputs destinations of the passengers into a destination call control and books destination calls and determines an instantaneous load disposed in the elevator car with a load measuring device at a fixable point in time. In order to make uniform the waiting times of the passengers in the case of incorrect operation of the destination call control and to ensure, for all passengers, an optimized transport time with maximum transport capacity the method additionally compares the instantaneous load with a full load parameter and in the case of exceeding of the full load parameter activating a bypass function those floors for which destination calls are booked and which are passed during a half circuit of the fully loaded elevator car.
