PROCEDE ET DISPOSITIF D'ESTIMATION D'UNE VARIABLE DE PENTE DE LA ROUTE SUR LAQUELLE ROULE UN VEHICULE

摘要

The process involves measuring a speed (VM) of a vehicle and calculating an estimated speed (VE) of the vehicle. A difference between the estimated and measured speed is calculated. A corrective force (FC) due to a slope is calculated from the difference of the speeds. A slope variable is calculated from the corrective force owing to the slope. The estimated speed is calculated by doing an algebraic sum of matrix forces or calculated resistance applying on the vehicle. An Independent claim is also included for a control device of a motor device or a transmission device of a motor vehicle.
