ABSTRACT:
An apparatus for predicting a load in a car of an elevator, includes a first circuit for determining each floor getting-off proportion which indicates the ratio of the number of passengers getting off the car at each floor to the total number of passengers at that time, a second circuit for determining the number of in-car passengers to be increased in compliance with a hall call scheduled to be responded to, and a third circuit for decreasing the incremental number of passengers determined by the second circuit in accordance with the each floor getting-off proportion determined by the first circuit and for outputting the predicted in-car load calculated using the decreased number of passengers, whereby the predicted in-car load can be calculated with a small amount of data and within a short period of time.
