Tyre pressure monitoring system
First Claim
1. 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 which stores a list of identity tags captured by said receiver from signals transmitted by said transmitters; and
a list of associated confidence values for each identity tag indicative of a confidence that said stored identity tag corresponds to a transmitter of a tyre associated with said vehicle.

Abstract
A tyre pressure monitoring or warning system comprising at least one receiver (112) responsive to signals transmitted by transmitters (106, 107, 108, 109) associated with one or more tyres (102, a, b, c, d, 104) the system including a memory which stores a list (150, 152) of identity tags (156) captured by the receiver (112), and a list of associated confidence values (158) for each identity tag (156) indicative of the confidence that the stored identity tag (156) corresponds to a transmitter (106, 107, 108, 109) that belongs to the vehicle. The list may be split into a member (150) and a candidate (152) list comprising those identity tags (156) that are deemed to refer and that possibly refer respectively to transmitters (106, 107, 108, 109) associated with the vehicle respectively. Initiators (114) may be provided to initiate transmission from the transmitters (106, 107, 108, 109) in order to locate the position of each tyre (102a, b, c, d, 104).

53. A tyre pressure warning system comprising:
-
an initiator associated with each road wheel of a vehicle which is in use;
a receiver which receives signals from any transmitters which are within an operational range of said receiver;
a processor which processes said received signals, and;
a memory in which is stored a list of identity tags captured by said receiver from said received signals and a list of associated confidence values for each identity tag indicative of a confidence that the system has that said identity tag corresponds to a transmitter that belongs to said vehicle;
said processor being adapted to learn which transmitters belong to said vehicle from said stored confidence values, and to learn where said learnt transmitters are located on said vehicle by monitoring in turn signals received from said transmitters in response to a prompt from each initiator. - View Dependent Claims (54, 55, 56, 57)
