A method of estimating a mass of a vehicle. If a yaw rate is smaller than a reference value, a straight direction model algorithm is applied to obtain an estimated mass. If a measured speed and a measured steering angle are larger than reference values, a lateral direction model algorithm is applied to obtain another estimated mass. If a measured vertical acceleration is larger than a reference value, a vertical direction model algorithm is applied to obtain yet another estimated mass. If each of the estimated masses is in an allowable range, and is constant for a given time period, the masses are applied to a recursive least square method, thereby estimating the mass of the vehicle.
