From what I've seen over the last 5 or 6 years, there seems to be at least 4 concepts of determining and reporting problems to the operator.
In the determination portion, it looks like the vast majority use:
either a pressure transducer in the tire/wheel assembly, either a band mounted or valve stem mounted RF transmitted signal
or
some form of speed sensor compared among tires
are there others in common use.
In the reporting, it seems that almost all transmit from the tire/wheel assembly to ONE receiver in the vehicle. However, I understand some have a shorter range transmitter and a receiver per wheel position ... which I suppose has the advantage of no relearning when tires are replaced or rotated.
Are there others? What manufacturers and models use the per wheel position receiver system?
Curiosity only, no need to know.
