PROBLEM TO BE SOLVED: To provide a calculation method of a new travel resistance curve capable of narrowing an error range related to the travel resistance curve, when calculating the travel resistance curve.SOLUTION: A travel resistance curve calculation device 1 calculates an approximate speed formula v(t) based on speed data 310 obtained by coasting travel, related to each of a plurality of coasting travels, and calculates a travel resistance part curve 10 in a speed area related to the coasting travel, and further calculates an approximate curve based on a plot point along the travel resistance part curve 10 classified by the coasting travel, and calculates a travel resistance curve 20 in a whole speed area.SELECTED DRAWING: Figure 2 |
