Abstract

A tire pressure monitoring system (10) and method for monitoring the pressure in at least one tire (12) supporting a vehicle (14) is disclosed. The system (10) comprises at least one sensor (30) mounted on the at least one tire (12) for measuring a pressure and a temperature of the at least one tire (12); means for transmitting the measured pressure data (62) and temperature data to a processor (38, 48); and a tire pressure model (54) being executed on the processor (38, 48), the tire pressure model (54) including: a driving event extractor (56) to extract cold pressure data (60) from the measured pressure data (62); a temperature compensator (64) to generate a compensated cold tire pressure (68) from the cold pressure data (60); a noise filter (70) to filter sensor noise and generate a filtered cold tire pressure (72) from the compensated cold tire pressure (68); a detection module (76) receiving the filtered cold tire pressure (72) and determining an air pressure leak rate of the at least one tire (12); and a leak notification (86) corresponding to the air pressure leak rate generated by the tire pressure model (54).
