47 ABSTRACT OF THE DISCLOSURE A speed pattern generator, and method of genera- ting a speed pattern, for use by an elevator car during a run to a target floor. The speed pattern includes a time based portion and a distance-to-go based portion. Calcula- tions during the time based portion are minimized by calculating spaced points or decision speeds on the acce- leration portion of the desired speed pattern. The points selected are those points at which decisions must be made as to whether the acceleration portion of the pattern should be continued. The pattern is changed at a predeter- mined jerk limited rate between the decision points, until a decision is made which indicates acceleration should be reduced to zero, either because the maximum desired magni- tude of the speed pattern is being approached, or because the advanced floor position (AVP floor) of the elevator car has reached the target floor. A final and single calculation during the time based portion is then made, which uses the latest decision speed to calculate the desired slowdown distance for the elevator car. When the elevator car reaches the calculated slowdown distance, a distance to-go speed pattern is generated, which is sub- stituted for the time based pattern when the two patterns have a predetermined relationship.
