A method of localizing the location of a received signal from a tire pressure
sensor
includes sending an AM identification signal. The AM signal is adjusted for speed
such that the frequency of the signal equals a constant multiplied by the speed
of the vehicle. Each of the tire locations on a vehicle have an expected sequence
of black-out points in the signal received by a receiver at any point on the vehicle.
That is, given a particular vehicle design, the AM signal described above would
be received at a receiver with an expected sequence of received peaks and black-out
points. Since the frequency of the signal is adjusted for speed, the received signal
will accurately allow the location of black-out points to be utilized to identify
the tire location for a particular signal.
