METHOD FOR VALIDATING THE MEASUREMENT SUPPLIED BY AN ACCELEROMETER IN A MOTOR VEHICLE AND USE FOR ESTIMATING SLOPE

摘要

The invention concerns a method for validating an acceleration measurement ?^mes 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^mes using said accelerometer, computing an acceleration ?o^m using a freewheeling vehicle model, computing a residual r defined as the difference between the measured acceleration ?o^mes and the computed acceleration ?o^m, comparing said residual r to a given threshold, validating the measured value ?^mes in case of negative comparison.
