Abstract
Disclosed are methods and devices for predictive maintenance of at least one component of a road vehicle. The general principle is based on the combination of the ranges of values of parameters that represent the wear of a road vehicle component. The method includes observing the duration of use of combinations of ranges of values in order to deduce therefrom a wear profile which is compared with a predetermined wear profile. This mechanism makes it possible to reduce the amount of information to be stored.
Claims20
A method for predictive maintenance of at least one component of a road vehicle, the component being connected to a computer, the method comprising the following steps:
- identifying, by means of the computer, a plurality of predetermined parameters, each of which represents the wear of the component, each wear parameter possibly taking a value in a first predetermined range of values,
- dividing each first range of values, by means of the computer, into a plurality of predetermined intervals,
- combining, by means of the computer, some or all of the intervals of one first range of values with some or all of the intervals of the other first ranges of values, according to a first predetermined combination pattern, so as to obtain a plurality of intervals of combination of parameters,
- determining, by means of the computer, a duration of use of each interval of combination of parameters as a function of at least one distance traveled by the road vehicle, so as to obtain a wear profile, and
- comparing the wear profile, by means of the computer, with a predetermined wear profile.
A device for the predictive maintenance of at least one component of a road vehicle, the device comprises a computer arranged to be connected to the component, wherein the computer is configured for:
- identifying a plurality of predetermined parameters, each of which represents the wear of the component, each wear parameter possibly taking a value in a first predetermined range of values,
- dividing each first range of values into a plurality of predetermined intervals,
- combining some or all of the intervals of one first range of values with some or all of the intervals of the other first ranges of values, according to a first predetermined combination pattern, so as to obtain a plurality of intervals of combination of parameters,
- determining a duration of use of each interval of combination of parameters as a function of at least one distance traveled by the road vehicle, so as to obtain a wear profile, and
- comparing the wear profile with a predetermined wear profile.
