METHOD AND DEVICE FOR DETECTING THE DYSFUNCTION OF A GAS PRESSURE SENSOR IN A VEHICLE TIRE
First Claim
1. A method (2) for detecting the malfunctioning of a sensor (11) of the pressure of a gas inside a tire of a vehicle, characterized in that it comprises at least:
- a step (20) of determining whether a predefined gas temperature variation detection criterion is verified,if a temperature variation is detected, a step (21) of determining whether a predefined criterion for detection of the variation of the pressure, measured by the pressure sensor, is verified,if a pressure variation is not detected, a step (22) of notifying that a malfunction of the pressure sensor has been detected.

Abstract
A method (2) for detecting the malfunctioning of a sensor (11) of the pressure of a gas inside a tire of a vehicle includes at least a step (20) of determining whether a predefined gas temperature variation detection criterion is verified. If a temperature variation is detected, the method (2) includes a step (21) of determining whether a predefined criterion for detection of the variation of the pressure, measured by the pressure sensor (11), is verified. If a pressure variation is not detected, the method (2) includes a step (22) of notifying that a malfunction of the pressure sensor (11) has been detected. A device for detecting the malfunctioning of a sensor (11) of the pressure of a gas inside a tire of a vehicle is also described.
