Abstract
A method for estimating a mass of a vehicle including 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. It is possible to estimate the mass of the vehicle at high accuracy.
