PROBLEM TO BE SOLVED: To provide a traveling distance correction device which accurately corrects traveling distance, even of a plurality of distance exist before correcting the traveling distance. SOLUTION: One shaft is selected from among a plurality of shafts by a shaft selection unit 6, and the traveling distance for an electric vehicle is calculated by a distance calculation unit 7 according to the revolution and wheel diameters of the selected shaft. The detection width of a correction ground element is calculated by a ground element detection width calculated unit 8 according to the maximum diameter and minimum diameter among the wheel diameters. If a plurality of target positions at which the electric vehicle is to be stopped exists, the deviations of the target stopping positions the added to the detection width by an adder 9. When the traveling distance calculated by the distance calculation unit 7 reaches a distance which is shorter than a distance data stored in a data memory unit 10 by a distance corresponding to the output of the adder 9, a ground element detection command unit 12 makes an ATS ground element detector start the detection of the correction ground element. When the ATS ground element detector detects the correction ground element, the traveling distance calculated by the distance calculation unit 7 is corrected to be the distance data stored in the data memory unit 10. |
