Methods and apparatus for determining the orientation of a tire mounted device

A method of determining an orientation of a tire mounted device with respect to a wheel rim using an acceleration sensor. With the wheel in a designated orientation and not rotating, a polarity of acceleration along a vertical axis is determined. Then it is determined which of a first absolute orientation or a second absolute orientation the tire mounted device is in depending on the determined polarity. The determined absolute orientation is correlated with the designated orientation to determine which of a first or second orientation with respect to the wheel rim the tire mounted device is in.

Tire-mounted sensor, diagnosis history memory device and diagnosis notification device

A condition in which an abnormality can occur in a tire is accurately detected on the basis of a detection signal from an acceleration sensor used to detect a road surface state and a possibility that an abnormality has occurred in the tire is also detected. In addition, the detection result is stored as a diagnosis history. The diagnosis history or the possibility that an abnormality has occurred in the tire are notified through a notification device in a vehicle body side system so that a user is informed in advance of the possibility that an abnormality has occurred in the tire. In addition, when the diagnosis history is checked through a tool in a car repair shop, etc., the diagnosis history stored in a tire-mounted sensor is read out. Accordingly, the possibility of abnormality of the tire can be informed also in the car repair shop, etc.
