1. A method for monitoring a parameter of a tire for a vehicle having a plurality of conductive components which form an electromagnetic path with first and second ends, the method comprising the steps of:
- generating a signal indicative of a parameter of the tire using a sensor disposed within the tire;
transmitting the generated signal along the electromagnetic path by introducing the generated signal to the electromagnetic path first end wherein the electromagnetic path includes a ground plane of the vehicle;
receiving a path signal at the electromagnetic path second end, the path signal being responsive to the generated signal; and
monitoring the tire parameter by monitoring the path signal.

Abstract
The present invention relates to a method and system for monitoring a parameter of a vehicle tire. In one embodiment, a detector unit disposed within the tire communicates with a central receiver unit over an electromagnetic path comprising one or more conductive components of the vehicle. Other embodiments of the invention include additional communications links for receiving information from and controlling the detector unit and the receiver.
