Abstract
Abstract A system and method for monitoring vehicle tire pressure. A tire pressure monitor for each tire includes a pressure sensor for sensing tire pressure and a transmitter for transmitting a tire pressure signal representative of the sensed tire pressure. A receiver for mounting on the vehicle receives the tire pressure signals, and includes an antenna to be located at a vehicle site. Each tire pressure signal has an amplitude and, for each tire location, the amplitude has a unique pattern over time for the antenna site. A controller for mounting on the vehicle communicates with the receiver and collects and processes the tire pressure signals to automatically identify the tire location associated with each tire pressure signal based on the unique amplitude patterns. The controller further generates control signals for use in conveying tire pressure and location information to a vehicle occupant.
