Abstract: The invention relates to a method of processing measurement signals from a movement senor on board a motor vehicle, according to which, initially, and in a preliminary phase, a reference value AcOff, called offset value, is stored, representative of the value of the signal output by the movement sensor, with the vehicle stopped, a so-called noise value Bb representative of the white noise of said sensor, and an acceleration value Sa determining a running threshold of the motor vehicle.

Abstract: A method of processing measurement signals from a movement sensor on board a motor vehicle, wherein in a preliminary phase, a reference offset value is stored, representative of the value of the signal output by the sensor, with the vehicle stopped, a noise value representative of the white noise of the sensor, and an acceleration value determining a running threshold of the vehicle. Then, throughout the life of the vehicle, sequences of successive measurements are taken of the value of the signal output by the sensor, and, for each sequence, the stored offset value is subtracted from each measure value and each calculated value is compared with the stored running threshold. Information representative of a stopped state is transmitted only if, the calculated values are less than the stored running threshold and roughly equal to each other with a tolerance margin corresponding to the stored noise value.
