Abstract
An elevator system having an elevator car, a running speed pattern generator, and a landing speed pattern generator. The landing speed pattern generator includes a plurality of different landing patterns stored in memory. When the elevator car enters the landing zone of the target floor, the magnitude of the running speed pattern is detected and a landing speed pattern is selected in response to this magnitude. The selected landing speed pattern is substituted for the running speed pattern, to enable the elevator car to land smoothly and accurately at floor level, notwithstanding errors in the running speed pattern.
