Patent ID: 7239948

Claim:
A tyre pressure monitoring system for a vehicle comprising: at least one receiver responsive to signals transmitted by transmitters, with each transmitter associated with a vehicle tyre; a memory; a list of identity tags captured by said receiver from signals transmitted by said transmitters stored in said memory; a list of confidence values also stored in said memory, each of said confidence values associated with one of said identity tags; and a control unit in communication with said receiver and said memory, said control unit operative to modify said confidence values with each of said confidence values being indicative of a confidence that said associated stored identity tag corresponds to a transmitter of a tyre associated with said vehicle such that, over time, the system is able to capture and learn the identities of tyres that belong to the vehicle and distinguish from tyres that do not belong to the vehicle, said control unit also operative to monitor at least one parameter of said vehicle and said received signals to determine a confidence value associated with an identity tag with one of said at least one parameters being a speed of said vehicle.
