Abstract
A method for calculating running resistance of a vehicle includes: calculating, by a controller, an integrated value obtained by integrating a torque of a driving source of the vehicle before the vehicle reaches a reference speed after the vehicle starts; and calculating, by the controller, the running resistance of the vehicle including rolling resistance based on the integrated value of the torque of the driving source.
