ABSTRACT:
An elevator system including a variable speed motive means is disclosed wherein the motive means is controlled in response to a selected motion profile to effect desired operation of the elevator car. Multiple elevator car motion profiles are stored and a appropriate profile is selected to operate the elevator car such that the level of service necessary to meet demand is provided while operating the elevator cars at reduced acceleration and jerk rates to provide increased ride comfort. Appropriate motion profiles are selected based on factors such as demand for elevator service and whether the building is in an up-peak or down-peak traffic period.
