Method for adapting the strategy for acquiring measurements of radial acceleration of the wheels of a vehicle
First Claim
1. A method for adapting the strategy for acquiring measurements of a radial acceleration of wheel sensors of a tire pressure monitoring system of a motor vehicle during phases in which the vehicle is stationary, in which the wheel sensors periodically measure parameters pertaining to tires of corresponding wheels, namely at least pressure, temperature and acceleration parameters, the method comprising:
- switching the radial acceleration measurement acquisition strategy of a wheel sensor during “
non-running”
phases of the vehicle, between at least two state-of-activity modes, switching from a so-called “
sleep”
acquisition mode to a so-called “
awake”
acquisition mode when a pressure event is detected by the tire pressure monitoring system of the motor vehicle, andmeasuring the radial acceleration according to a period of significantly longer duration in “
sleep”
mode than in “
awake”
mode.

Abstract
A method for adapting the strategy for acquiring measurements of the radial acceleration of the wheel sensors of a tire pressure monitoring system of a motor vehicle during phases in which the vehicle is stationary, in which the wheel sensors periodically measure parameters pertaining to the tires of the corresponding wheels, namely at least pressure, temperature and acceleration parameters. The method includes switching the radial acceleration measurement acquisition strategy of a wheel sensor during the “non-running” phases of the vehicle, between at least two state-of-activity modes, switching from a so-called “sleep” acquisition mode to a so-called “awake” acquisition mode when a pressure event is detected by the tire pressure monitoring system of the motor vehicle, the radial acceleration then being measured according to a period of significantly longer duration in “sleep” mode than in “awake” mode.
