| description | The invention discloses a rail transit vehicle traction system energy efficiency test method and system with high test precision. The method comprises the following steps: acquiring an original line data table; dividing the original line data table into a plurality of candidate short strokes, and calculating characteristic parameters of each candidate short stroke; screening according to the characteristic parameters to obtain a standard short stroke; splicing the standard short strokes in sequence to obtain an overall V-F distribution probability; calculating a vehicle speed-traction distribution probability X1 of the to-be-tested short stroke combination according to the standard short stroke; performing nonparametric test on the X1 and the overall V-F distribution probability to obtain a test value P1; selecting a to-be-tested short stroke combination corresponding to the minimum P1 value as a whole vehicle dynamic typical working condition, obtaining a whole vehicle steady-state typical working condition, |
