摘要:
The invention relates to a method for estimating the interval which contains the total weight of a motor vehicle, which includes defining at least two weight intervals (I 1 , I2), determining a first situation (M11) in which the total weight of the vehicle belongs to the first interval (I1) and a second situation (M12) in which the total weight (m) of the vehicle belongs to the second interval (I2), calculating the probability (P(M11 \x), P(M12 \x)) of being in the first or second situation (M11, M12) knowing a value (x) of the weight, calculating the risk (R11, R12) of selecting the wrong interval (I1, I2) in accordance with the calculated probability and the cost associated with an incorrect decision M, and determining the interval (I1, I2) which contains the total weight of the vehicle in accordance with the risk (R11, R12).

The invention relates to a method and a system for monitoring a pressure of a tyre mounted on a wheel of a driving vehicle, the method comprising the following steps: measuring a temperature (Tm) relative to the immediate environment of the vehicle; estimating the weight (Me) of the vehicle; measuring at least one first oscillation frequency (Fm1) of the tyre in a first range of frequencies and a second oscillation frequency (Fm2) of the tyre in a second range of frequencies; and determining the pressure (Pc) of the tyre in accordance with the first (Fm1) and second (Fm2) oscillation frequencies and the temperature (Tm) measured as well as the estimated weight (Me) of the vehicle.
