Abstract
A method for determining an estimate of the mass of a motor vehicle for use in controlling the brake system of a motor vehicle, in which a driving force and a force of inertia acting instantaneously on the wheel being determined for all the wheels of the vehicle, and the instantaneous driving forces and inertia forces of all wheels as well as an instantaneous wind resistance of the motor vehicle are added up and divided by the instantaneous longitudinal acceleration of the vehicle to determine the estimate of the mass. In addition, the rolling resistance of the vehicle and/or a braking force acting instantaneously on the wheel is determined for all the wheels and taken into account in the addition.
