Method and system for mitigating false alarms in a tire pressure monitoring system for an automotive vehicle

A pressure monitoring system ( 12 ) for a tire ( 14 a) of an automotive vehicle includes a first pressure sensor ( 94 ) coupled to the wheel, a pressure transmitter ( 90 ) coupled to the pressure sensor ( 94 ) whereby the transmitter generates a pressure signal. A controller ( 22 ) is coupled to the...

Zusammenfassung:A pressure monitoring system ( 12 ) for a tire ( 14 a) of an automotive vehicle includes a first pressure sensor ( 94 ) coupled to the wheel, a pressure transmitter ( 90 ) coupled to the pressure sensor ( 94 ) whereby the transmitter generates a pressure signal. A controller ( 22 ) is coupled to the pressure transmitter. The controller ( 22 ) receives the pressure signal and in a first stage, compares the pressure signal to a pressure threshold to obtain a sensor status. In a second stage, the controller ( 22 ) qualifies the sensor status signal by generating a warning status in response to the sensor status.
