1. A method for estimating a mass of a vehicle comprising the steps of:

  • correcting a wheel torque of a vehicle during running by using a preliminarily obtained wheel torque necessary for running on a flat surface at constant speed, obtaining a regression line of the corrected wheel torque and an acceleration/deceleration of the vehicle, and estimating a mass of the vehicle on the basis of a slope of the regression line.
