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.
Claims18
A method (2) for detecting a malfunctioning of a sensor (11) of pressure of a gas inside a tire of a vehicle, comprising:
- a device comprising a pressure sensor executing a step (20) of determining whether a predefined gas temperature variation detection criterion is verified,
- when the device determines that a temperature variation is detected, the device executing a step (21) of determining whether a predefined criterion for detection of a pressure variation, measured by the pressure sensor, is verified,
- when the device determines that a pressure variation is not detected, the device executing a step (22) of notifying that a malfunction of the pressure sensor has been detected.
A device (1) for detecting a malfunctioning of a sensor (11) of a pressure of a gas inside a tire of a vehicle, comprising:
- means for determining whether a predefined gas temperature variation detection criterion is verified,
- means for determining whether a predefined criterion for detection of a pressure variation, measured by a pressure sensor, is verified, implemented when a temperature variation has been detected, and
- means for notifying that a malfunction of the pressure sensor (11) has been detected, implemented when a pressure variation has not been detected.
