1. A tire pressure monitoring system for monitoring the pressure in at least one tire supporting a vehicle, the system comprising:
at least one sensor mounted on the at least one tire for measuring a pressure and a temperature of the at least one tire;
means for transmitting the measured pressure data and temperature data to a processor; and
a tire pressure model being executed on the processor, the tire pressure model including:
a driving event extractor to extract cold pressure data from the measured pressure data;
a temperature compensator to generate a compensated cold tire pressure from the cold pressure data;
a noise filter to filter sensor noise and generate a filtered cold tire pressure from the compensated cold tire pressure;
a detection module receiving the filtered cold tire pressure and determining an air pressure leak rate of the at least one tire; and
a leak notification corresponding to the air pressure leak rate generated by the tire pressure model, wherein when the air pressure leak rate includes an air pressure rate loss of more than 20 percent of the air in the at least one tire within a 24-hour time period, the leak notification includes a first leak notification to stop the vehicle.
