Abstract

An automated arrangement selects one of a plurality of load weight bypass thresholds for an elevator car. The selection depends, for example, upon the car direction and the time of day. Alternative embodiments of the arrangement utilize in the selection either actual or estimated elevator car floor space. Fuzzy logic is used to estimate available floor space.
