Abstract
A tire monitor for use in conjunction with a remote tire monitoring system of a vehicle includes in one embodiment a dual-axis accelerometer and a control circuit. The control circuit determines position information such as the right/left position of the tire monitor on the vehicle in response to an acceleration signal from the dual axis accelerometer. The tire monitor transmits tire data and the position information to a control unit of a remote tire monitor system. The control unit determines additional position information such as front/rear position of the transmitting tire monitor by detecting signal strength of the transmission. This allows the system to automatically re-learn the position of tire monitors on the vehicle, even after tire rotation.
