1. Measurement method of the temperature of a mechanical part such as a wheel end of an automotive vehicle fitted with a thermal sensor, comprising the following steps:
measuring the temperature of the part with the thermal sensor at an initial measurement frequency,
broadcasting the measured temperature at an initial broadcast frequency,
determining if the last measured temperature is higher that a first preset temperature threshold, so that
i) if such is the case, the broadcast frequency is changed from the initial broadcast frequency to a higher broadcast frequency and the measurement frequency is changed from the initial measurement frequency to a higher measurement frequency,
performing a new measurement of the temperature of the part at the higher measurement frequency, broadcasting the measured temperature at the higher broadcast frequency,
ii) if it has been determined that the last measured temperature is lower or equal to the first preset temperature threshold, keeping the broadcast frequency and the measurement frequency unchanged, and resuming at the step of measuring the temperature of the part with the thermal sensor at the initial measurement frequency,
after broadcasting the measured temperature at the higher broadcast frequency, determining if the last measured temperature is higher than the first preset temperature threshold, so that
i) if such is the case, the process resumes at the step of performing a new measurement of the temperature of the part at the higher measurement frequency,
ii) if such is not the case, changing the broadcast frequency from the higher broadcast frequency to the initial broadcast frequency, and changing the measurement frequency from the higher measurement frequency to the initial measurement frequency, then resuming the process at the step of measuring the temperature of the part with the thermal sensor at an initial measurement frequency.
