Abstract (en)
[origin: WO2007045787A1] The invention concerns a method for validating an acceleration measurement ?<SUP>mes</SUP> supplied by an accelerometer in a motor vehicle. The invention is characterized in that said method includes steps which consist in: measuring, in freewheel phase, an acceleration ?o<SUP>mes</SUP> using said accelerometer, computing an acceleration ?o<SUP>m</SUP> using a freewheeling vehicle model, computing a residual r defined as the difference between the measured acceleration ?o<SUP>mes</SUP> and the computed acceleration ?o<SUP>m</SUP>, comparing said residual r to a given threshold, validating the measured value ?<SUP>mes</SUP> in case of negative comparison.
