Abstract
A method for estimating the total mass of a motor vehicle by a recursive least squares algorithm. The method involves a vehicle longitudinal acceleration computing according to a fundamental dynamic equation by analysing errors by an acceleration variation caused by errors including a variation error of the vehicle mass with respect to a predetermined mass, declivity error of a surface on which the vehicle is placed, and model errors. The declivity is delivered by a declivity sensor or by declivity estimation mechanism.
