49,235 ABSTRACT OF THE DISCLOSURE An elevator system including an elevator car, and control apparatus for controlling its speed, including a speed pattern generator. The speed pattern generator provides a running speed pattern, and a slowdown speed pattern, wherein the deceleration rate of the slowdown speed pattern may be different than the acceleration and deceleration rates of the running speed pattern. Bumpless transfer from the running speed pattern to the slowdown speed pattern is achieved by forcing the slowdown speed pattern to match the magnitude of the running speed pat- tern just prior to transfer, and by initiating transfer when the rate of change of the running speed pattern equals the rate of change to be followed by the slowdown speed pattern after it is no longer forced to match the magnitude of the running speed pattern.
