Abstract

An exemplary device for controlling an elevator car motion profile includes a controller (64) that is programmed to cause an associated elevator car (62) to move with a motion profile that includes a plurality of jerk values (78, 82, 86, 90, 96, 100). The controller (64) is programmed to cause at least one transition (84, 88, 94, 98) between two of the jerk values to be at a non-instantaneous transition rate.
