摘要： The present application discloses a vehicle tire detection device, including a TPMS (Tire Pressure Monitoring System) sensor, an antenna matching network, and a terminal antenna. The TPMS sensor uses ASK/OOK/FSK transmission technology with a data transmission rate greater than 20kbps. The TPMS sensor is connected to the terminal antenna through the antenna matching network. The terminal antenna is one of a valve stem, a metal base, or a tire rim. In the present application, by enhancing a radio frequency data transmission rate, an aim is to reduce a radio frequency transmission time of the sensor, thereby reducing a transmission power consumption. By shortening the transmission data time, an aim is to enhance a signal transmission penetration and improve a radio frequency anti-interference capability. Using a valve stem, metal base, or tire rim as the terminal antenna enhances a length and area of the antenna, leading to higher signal conversion efficiency and better transmission stability of the sensor on the vehicle. The terminal antenna being on the outside of the tire body is beneficial for increasing the strength of the wireless signal, with the same transmission power of the TPMS sensor, it is easier to achieve wireless communication over a longer distance, and the error rate is reduced.

摘要： A vehicle (10) includes a front wheel assembly (11) and a rear wheel assembly (12) having different outer diameters. A wheel position identifying device (50) includes a reception circuit (55) and an identifying device control unit (51). The reception circuit (55) is configured to receive a first transmission signal and a second transmission signal. The first transmission signal is transmitted from a transmitter (31) attached to the front wheel assembly (11) at a specific rotational position of the front wheel assembly (11). The second transmission signal is transmitted from a transmitter (31) attached to the rear wheel assembly (12) at a specific rotational position of the rear wheel assembly (12). The identifying device control unit (51) is configured to determine whether each of the transmitters (31) is attached to the front wheel assembly (11) or the rear wheel assembly (12) based on a reception interval of the first transmission signal and a reception interval of the second transmission signal.

摘要： Each of transmitters attached to respective wheel assemblies transmits transmission data when the wheel assembly reaches any of specific angles set at equal angular intervals. A receiver mounted in the vehicle obtains the rotation angles of the wheel assemblies from a rotation angle detecting section upon reception of the transmission data and obtains specific rotation angles by correcting the obtained rotation angles by using the value of the angle difference between the specific angles. The specific rotation angles are values that can be regarded as rotation angles that are obtained upon reception of the transmission data transmitted at the same specific angle. The receiver identifies the correspondence between ID codes included in the transmission data and the wheel assemblies by using the specific rotation angles.

摘要： All tire systems, including tire systems that include self-inflating devices, need to have the ability to regularly and reliably monitor and report vehicle and tire conditions for safety reasons. For a self-inflating tire, this can be accomplished by monitoring the operation of the self-inflation system, and assessing if it is consistent with a tire in good condition.
