Device and method for assisting inflation
First Claim
1. A method for assisting with non-critical inflation of tires for a vehicle fitted with a set of tire pressure sensors, a set of tire temperature sensors, and a microprocessor, the method comprising:
- supplying the microprocessor with pressure data relating to a pressure of at least one of the tires of the vehicle, the pressure data being measured by at least one of the tire pressure sensors;
supplying the microprocessor with temperature data relating to a temperature of at least one of the tires of the vehicle, the temperature data being measured by at least one of the tire temperature sensors;
with aid of the microprocessor supplied with the pressure data and the temperature data, notifying a user of a possible non-critical under-inflation condition present in at least one of the tires of the vehicle; and
testing, by the microprocessor, to determine whether a condition is acceptable for inflation, if a verification of a non-critical under-inflation condition is received, and determining that the condition is acceptable for inflation upon simultaneous occurrence of;
a non-critical under-inflation condition for at least one of the tires of the vehicle, based on measurements by at least one of the tire pressure sensors,the tires of the vehicle not being in a hot state due to running of the vehicle, based on measurements by the tire temperature sensors, andthe tires of the vehicle not being in a hot state due to heating by sun exposure, based on measurements by the tire temperature sensors; and
,when an acceptable condition for inflation is determined, transmitting a corresponding signal.

Abstract
A device and a method for aiding inflation for a vehicle involves obtaining access to vehicle tire pressure and temperature data, and utilizing an under-inflation detection module and an inflation condition testing module, thus making it possible to carry out a test for detecting a possible optimal inflation condition if the following criteria are met:—there is a non-critical under-inflation state for at least one of the vehicle tires;—the tires are not in an overheated state;—and the tire state is unchanged by sunlight. When the test module determines the optimal inflation condition, a signal is outputted. Such a method causes tire inflation to be carried out under favorable conditions actually corresponding to the reference value provided by the manufacturers.
