DEVICE FOR MEASURING ACCELERATION IN A MOTOR VEHICLE

摘要

The invention concerns a device for measuring acceleration in a motor vehicle, characterized in that it comprises: an accelerometer (100) arranged in said vehicle, adapted to measure an acceleration ?^mes, means (200) for detecting the vehicle freewheel, means (400) for computing an acceleration ?o^m using a freewheeling model of the vehicle, means for computing a residual r defined as the difference between the acceleration ?o^mes measured in free wheel and the computed acceleration ?o^m, means for validating the measured acceleration ?^mes by comparing said residual r to a given threshold.
