    Abstract: A tire pressure detection system with separated antennas includes a detection end and a receiving end. The detection end includes tire pressure detectors to detect the tire to obtain the information of tire status. The tire pressure detectors output the information of the tire status in the form of radio frequency signal and Bluetooth signal. In addition to the transmission to the built-in tire-pressure receiving device, the information of the tire status also can be displayed on the in-vehicle audio-video device and the user's mobile device.

    Abstract: A tire with printed sensors includes a pair of bead areas, a tread disposed radially outwardly of the bead areas, and a pair of sidewalls, including an inboard sidewall extending from a first bead area to the tread, and an outboard sidewall extending from a second bead area to the tread. A carcass extends toroidally between each of the bead areas radially inwardly of the tread, and an innerliner is formed on an inside surface of the carcass. A plurality of sensors are printed on the innerliner in a sidewall zone of the inboard sidewall or in a sidewall zone of the outboard sidewall, and are configured to measure deformation in the sidewall zone. The plurality of sensors are daisy-chained to provide a single deformation signal that is based on the measured deformations of the plurality of sensors.

    Abstract: A tire inflation assembly includes an air chuck that has a pair of outlets that has a direction of air flow which is oriented at a unique direction with respect to each other. In this way the air chuck can be attached to the valve stem at a variety of orientations to enhance employing the air chuck to inflate the tire. The air chuck includes a locking mechanism which engages the valve stem for retaining the air chuck on the valve stem. The locking mechanism is urgeable to disengage the valve stem to remove the air chuck from the valve stem. A pressure gauge is integrated into the air chuck to display the air pressure in the tire when either of the outlets is attached to the valve stem.

    Abstract: An air pressure abnormality determination system determines whether an air pressure abnormality in which an air pressure of at least one of multiple front tires and multiple rear tires drops. The front tires are front wheels of a vehicle. The rear tires are rear wheels of the vehicle and of which outer diameter is different from an outer diameter of the front tires. A determination is made on whether the air pressure abnormality occurs using a corrected wheel speed obtained by correcting one of a front wheel speed that is a wheel speed of the front wheels and a rear wheel speed that is a wheel speed of the rear wheels based on the outer diameter of the front tires and the outer diameter of the rear tires and an uncorrected wheel speed that is the other of the front wheel speed and the rear wheel speed that is uncorrected.

    Abstract: A method to calibrate a Weigh in Motion (WIM) sensor that is arranged in a road flush with a road surface for determining a force exerted on the road surface by a vehicle's wheel transgressing the WIM sensor uses an evaluation unit that calculates the wheel force upon receiving the vehicle's velocity and a distance signal from a first device fixed on the vehicle and coordinates the wheel force with a synchronized signal from the WIM sensor to generate a calibrate function for the WIM sensor. The evaluation unit continuously adjusts the wheel force to take into account one or more of wheel pressure, wheel temperature, wheel tilt and vehicle acceleration. A system employing the method includes the vehicle, the evaluation unit, the first device, a synchronization device such as a GPS unit, and sensors for one or more of pressure, temperature, tilt and acceleration.

    Abstract: A method for reading pressure may include reading, by a first device, an acceleration of a pressure sensor, wherein the pressure sensor is encapsulated in a medium, and wherein the acceleration alters a reading of the pressure sensor and reading, by a second device, a pressure reading from the pressure sensor. If an output criteria is met, an adjusted pressure reading is produced. A system for reading pressure includes a first device coupled to the pressure sensor and configured to read an acceleration of the pressure sensor. A second device may be configured to read a pressure from the pressure sensor wherein, if an output criteria is met, to adjust the measured pressure of the pressure sensor, based on the measured acceleration, to produce an adjusted pressure reading. An output device is configured to receive an output of the second device and to output an output pressure reading.

    Abstract: A near-field communication-based tire pressure monitoring system, a sensor, a tire, and a vehicle. The tire pressure monitoring system comprises a server (101), a terminal (102) supporting near-field communication, and a tire pressure monitoring sensor (103) supporting near-field communication. The terminal (102) obtains from the server (101) update information for updating the tire pressure monitoring sensor (103), and then the update information is transmitted to the tire pressure monitoring sensor (103) by establishing a near-field communication connection between the terminal (102) and the server (101), so that the tire pressure monitoring sensor (103) realizes information reconfiguration or programming process. The terminal (102) is connected to the tire pressure monitoring sensor (103) by means of near-field communication, and compared with wireless communication, the near-field communication avoids the interference of irrelevant signals, guaranteeing the normal communication process. Since the interference of irrelevant signals is avoided, hang-up prevention is encrypted in the near-field communication process without additionally increasing a processing packet, and the cost is reduced.
