Abstract: An apparatus for sensing pressure in vehicle tires includes an interrogator (102) for providing a tire pressure interrogation signal, and a tire pressure monitor (70) for sensing pressure within a first tire (24) of the vehicle (20) and providing an actual tire pressure signal. A first wheel speed sensor (42) associated with the first tire (24) provides a reference wheel speed signal upon movement of the vehicle (20). A second wheel speed sensor (40) associated with a second tire (22) of the vehicle (20) provides a wheel speed signal upon movement of the vehicle. A controller (60) activates the interrogator (102), monitors the actual tire pressure signal, and correlates the reference wheel speed signal with the wheel speed signal from the second wheel speed sensor (40) for determining a tire pressure value of the second tire (22).

Abstract: An arrangement for provision of vehicle tire sensory information while a tire (12) is mounted on a wheel rim (10) of a vehicle. A sensor unit (16) includes a tire condition sensor (e.g., electronics 38), a signal transmitter (36), and a housing (20) that contains the sensor and the transmitter. The housing (20) has a mounting hole. A stud (18) is welded to the rim (10) and extends into the space bounded between the tire (12) and the rim (10). The stud extends through the mounting hole of the sensor housing (20). A retainer (e.g., 26) extends between the sensor housing (20) and the stud (18) such that the sensor housing is held fixed relative to the stud.

Abstract: An apparatus for associating tires with tire locations of a vehicle includes two sensors, each sensor having an associated tire. Each sensor transmits an associated sensor identification in response to receipt of an interrogation signal. The interrogation signal is provided so that the two sensors transmit at different rates. A controller is responsive to receipt of transmitted identification signals for associating each sensor with a tire location and thereby associating the tires with tire locations of the vehicle.

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.

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 sensor module (14) for a vehicle (10) includes a tire condition sensor (78, 84, 88) operative to sense a condition of an associated vehicle tire (20) and provide a tire condition signal having a characteristic indicative thereof. A motion detector (32) is operative to detect movement of the associated vehicle tire (20) and provide a motion signal that indicates movement of the associated vehicle tire (20). The sensor module (14) also includes a transmitter (44) which is operative to transmit a tire transmitter signal having a characteristic based on the tire condition signal. A controller (74) has one operating mode responsive to the motion signal in which the controller (74) controls the transmitter (44) to intermittently transmit the tire transmitter signal. The controller (74) has another operating mode also responsive to the motion signal in which the controller controls the transmitter (44) to transmit the tire transmitter signal only after the controller determines that the tire condition signal indicates that the sensed tire condition is either above or below a first predetermined threshold. The controller (74) also controls the tire condition sensor (78, 84, 88) to sense the tire condition of the associated vehicle tire (20) during each of the operating modes.
