    • The invention relates to a method for filtering information emitted, on the basis of pressure measurements taken by a pressure sensor mounted on a wheel of a vehicle equipped with a tire, to a central unit mounted on the vehicle. According to this method, a value representative of the pressure of the air in the tire is measured periodically, with a period θ, and from this any possible variations ΔP in pressure between the values of the pressures successively measured are deduced; in parallel, with the same period θ, a value representative of the temperature of the air in the tire is measured. In addition, when there is a variation ΔP in pressure between two measured pressure values, that is greater in terms of absolute value than a predetermined threshold Sp, the variation ΔT between the two temperature values measured at the same instants as the measured pressures is calculated. The emission of a signal representative of a variation in pressure to the central unit is commanded only if the comparative change in the pressure and in the measured temperature might be representative of a variation of the amount of air in the tire.
    • 本发明涉及一种基于安装在配有轮胎的车辆的车轮上的压力传感器进行的压力测量,将发出的信息过滤到安装在车辆上的中央单元的方法。 根据该方法,周期性地测量表示轮胎中的空气的压力的值,并且从该值可以推断出连续测量的压力值之间的任何可能变化压力值ΔP; 在相同的周期θ的情况下,测量表示轮胎中的空气的温度的值。 另外,当在两个测量的压力值之间存在压力变化ΔP时,其绝对值大于预定阈值Sp时,计算在与测量的压力相同的时刻测量的两个温度值之间的变化ΔT 。 只有当压力和测量温度的比较变化可能代表轮胎中的空气量的变化时才指示代表中央单元的压力变化的信号的发射。

    • 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.

    • 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. Then, according to this method, and throughout the life of the vehicle, sequences of n successive measurements are taken of the value Ac(t) of the signal output by the movement sensor, and, for each of these sequences, the stored offset value AcOff is subtracted from each of the n measured value and each of the duly calculated values is compared with the stored running threshold, and information representative of a stopped state of the vehicle is transmitted if, and only if, the n calculated values are all less than the stored running threshold and roughly equal to each other with a tolerance margin corresponding to the stored noise value.
