Abstract
The invention relates to a method for aiding inflation for a vehicle, comprising access to vehicle tire pressure (10) and temperature (20) data, an under-inflation detection module (50), and an inflation condition testing module (30) 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 (30) 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. The invention also relates to the corresponding device for aiding inflation.

10. A method for assisting with inflation of tyres for a vehicle fitted with a set of tyre pressure sensors, a set of tyre temperature sensors, and a microprocessor, the method comprising:
-
supplying the microprocessor with pressure data relating to a pressure of at least one of the tyres of the vehicle; supplying the microprocessor with temperature data relating to a temperature of at least one of the tyres of the vehicle; with aid of the microprocessor supplied with the pressure data and the temperature data, notifying a user of a possible under-inflation condition present in at least one of the tyres of the vehicle; and testing, by the microprocessor, to determine whether a condition is acceptable for inflation, if a verification of an under-inflation condition is received, provided that simultaneously; a non-critical under-inflation condition has been detected for at least one of the tyres of the vehicle, the tyres of the vehicle are not in a hot state, and a state of the tyres of the vehicle is not changed by sun exposure; and
,when an acceptable condition for inflation is determined, transmitting a corresponding signal. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A device for assisting with inflation of tyres of a vehicle, the device comprising:
-
an input that receives pressure data of at least one of the tyres of the vehicle; an input that receives temperature data of at least one of the tyres of the vehicle; an under-inflation detection module that utilizes the pressure data and the temperature data to detect a possible under-inflation condition present on one or more of the tyres of the vehicle; and a testing module that carries out tests to determine whether a condition is acceptable for inflation, the tests being carried with aid of a microcprocessor if a verification of an under-inflation condition is received, wherein the microprocessor is supplied with the pressure data, the microprocessor is supplied with the temperature data, the microprocessor determines whether a condition is acceptable inflation if the verification of an under-inflation condition is received, provided that simultaneously; a non-critical under-inflation condition has been detected for at least one of the tyres of the vehicle, the tyres of the vehicle are not in a hot state, and a state of the tyres of the vehicle is not changed by sun exposure, and, when an acceptable condition for inflation is determined, the testing module transmits a corresponding signal. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
