Abstract: A tire condition communication system (10) and method for a vehicle (12) that has a tire (e.g., 14A). A sensor (70), associated with the tire (e.g., 14A), senses at least one tire condition. A memory (66), associated with the tire (e.g., 14A), holds an identification. A transmitter arrangement (22 and 74), associated with the tire (e.g., 14A), transmits a signal (e.g., 24A) that indicates the held identification and the sensed tire condition. A receiver arrangement (28 and 30), associated with the vehicle (12), receives the transmitted signal (e.g., 24A). An identification update device is associated with the tire and is operatively connected to the memory (66). The update device receives an update identification and provides the received location identification to the memory (66) to be held as the held identification. An input device is manually actuated to provide the update identification. In one example, a receiver (46) at the tire and a manually actuated transmitter (44) provided the update and input devices. In another example, a switch (116) and a manually actuatable part (e.g., a valve stem part) at the tire provide the update and input devices.

Abstract: A tire condition communication system (10) for a vehicle (12) that has a tire (e.g., 14A). A sensor (e.g., 74), associated with the tire (e.g., 14A), senses at least one tire condition. A memory (e.g., 70), associated with the tire (e.g., 14A), holds an identification. Transmitter components (e.g., 80 and 22), associated with the tire (e.g., 14A) and operatively connected to the sensor (74) and the memory (70), transmit a condition signal (e.g., 24A) that indicates the held identification and the sensed tire condition. A vehicle-based unit (28) receives the transmitted condition signal (e.g., 24A) indicative of the held identification and the sensed tire condition. An identification provision unit (e.g., 42A), located on the vehicle (12) adjacent to the tire (e.g., 14A) and having a location identification, transmits the location identification in response to a request. A communication portion (e.g., 48A) of the tire condition sensor unit (e.g., 18A) communicates a request to the identification provision unit (e.g., 42A) to transmit the location identification. The tire condition sensor unit (e.g., 18A) receives the requested location identification and updates the held identification.
