1. A method to determine an estimate of a mass of a motor vehicle for use in controlling a brake system of the motor vehicle, the method comprising:
determining a driving force and a force of inertia acting instantaneously on a wheel being determined for all wheels of the vehicle;
determining at least one of a rolling resistance of the motor vehicle and a braking force acting instantaneously on the wheel for all wheels of the motor vehicle; and
adding up the instantaneous driving forces and the forces of inertia of all wheels plus an instantaneous wind resistance of the vehicle to provide a summation result, and dividing the summation result by an instantaneous longitudinal acceleration to determine the estimate of the mass, wherein the at least one of the rolling resistance of the motor vehicle and the braking force acting instantaneously on the wheel determined for all wheels of the motor vehicle are taken into account in the summation.
2. The method of claim 1, wherein an instantaneous braking force component due to a lateral force because of tire slip is determined for the wheels of a steering axle of the motor vehicle and is taken into account in determining the instantaneous driving forces and the forces of inertia of all the wheels.
3. The method of claim 1, wherein the summation of the instantaneous braking forces, the driving forces and the forces of inertia of all wheels as well as the instantaneous wind resistance and the rolling resistance of the vehicle is filtered to eliminate transient interference.
4. The method of claim 1, wherein the determined estimate of the mass is filtered to eliminate transient interference.
5. The method of claim 1, further comprising:
determining an instantaneous slope in the road surface; and
correcting the resulting estimate of the mass taking into account the determined slope.
6. The method of claim 1, further comprising:
subjecting the determined estimate of the mass to a plausibility check, and only using the estimate for controlling the brake system of the motor vehicle if the estimate is classified as plausible.
7. The method of claim 1, wherein the estimate of the mass is determined at short intervals, and a most recently determined estimate is used to control the brake system after it is at least one of corrected and filtered.
8. The method of claim 1, wherein the estimate of the mass is used to determine a coefficient of static friction of the vehicle.
9. The method of claim 1, wherein the estimate of the mass is used to improve an electronic braking force distribution.

What I claim as my invention is as follows:
1. A method, utilizing a small powerful electric motor and impellor, to draw vast quantities of cool odor-free air from the exterior of the toil bowl, simultaneously drawing small clouds of odorous gaseous molecules from the human body and associated excrements into a homogenizing unit.
2. A method, utilizing the motor-fan referenced in claim 1, operating at 3000 rpm to homogenize andor disperse small clouds of warm odorous gaseous molecules among many thousands of cool non-odorous exterior air molecules.
3. A method, utilizing dense material of activated charcoal, to filter by absorption and to cool widely dispersed warm odorous gaseous molecules.
4. A method of venting cooled homogenized and odor free air around scented granules into the surrounding toilet space at floor level.
5. A method, utilizing rails or spacers attached to the underside of the toilet seat, to create inlet and outlet for warm odorous and cool non-odorous molecules of air and to control the direction of air flow of these moving air masses to the homogenizing unit.
