PROBLEM TO BE SOLVED: To provide a new making method of a running curve that is improved in power consumption.SOLUTION: A running curve making device is constituted by combinations satisfying a predetermined representative condition among combinations of brake notches applied to each brake curved portion included in a basic running curve, and performs a preliminary search using a preliminary search tree 20 where the combinations of the brake notches in the basic running curve are assumed as a search start point. Then, an entire search is performed which uses the entire search tree 30 where the combinations of the brake notches minimized in the power consumption are assumed as the search start point by the preliminary search, and the running curve candidate applied with the combinations of the brake notches minimized in power consumption is assumed as the running curve improved in the power consumption to the basic running curve. The preliminary search tree 20 and the entire search tree 30 are configured so that the brake notch between the nodes connected in the edge is increased/decreased by one step, and a descendant node of a child node with the power consumption larger than that of a parent node is excluded from a search target in the search.SELECTED DRAWING: Figure 8 |
