Abstract: A tire pressure monitoring system monitors the pressure in at least one tire supporting a vehicle. The system includes at least one sensor mounted on the tire for measuring a pressure and a temperature of the tire. Transmission means transmit the measured pressure data and temperature data to a processor, and a tire pressure model is executed on the processor. The tire pressure model includes a driving event extractor to extract cold pressure data from the measured pressure data, and a temperature compensator to generate a compensated cold tire pressure from the cold pressure data. A noise filter filters sensor noise and generates a filtered cold tire pressure from the compensated cold tire pressure. A detection module receives the filtered cold tire pressure and determines an air pressure leak rate of the tire, and a leak notification corresponding to the air pressure leak rate is generated.

Abstract: A tire pressure monitoring system includes a first tire mounted on a first end of an axle and a second tire mounted on a second end of the axle. A first sensor is mounted on the first tire for measuring a pressure, and a second sensor is mounted on the second tire for measuring a pressure. The system includes means for transmitting measured pressure data from the first sensor and the second sensor to a processor. A tire pressure model is executed on the processor, and includes an aggregator that accumulates the measured pressure data from the first sensor and the second sensor. A noise filter filters sensor noise and generates filtered pressure data from the measured tire pressure data. A detection module receives the filtered pressure data and determines when a leak occurs in one of the tires. A leak notification is generated when the leak occurs.
