Abstract

A system and method for detection of a leak rate in a tire (12) supporting a vehicle (14) is disclosed. The system (10) comprises a sensor (30) mounted on the tire (12) for measuring a pressure (58) of the tire (12); means for transmitting measured pressure data from the sensor (30) to a processor (38, 48); and a filter module (54) configured for being executed on the processor (38, 48). The filter module (54) includes: a leak rate determination module (70), the leak rate determination module (70) being configured for receiving the measured pressure data and including a filter algorithm (72), the filter algorithm (72) being configured for determining a leak rate of the tire (12) from the measured pressure data; an accumulator (88) configured for calculating a cumulative leak score (92) from a plurality of leak rates; and a flag (90) configured for being generated by the filter module (54) when the cumulative leak score (92) exceeds a predetermined leak score threshold and for being transmitted to at least one of a vehicle control system and a display device (50) for actuation of the vehicle (14) in response to the flag (90).
