A tire pressure monitor can include: a pressure sensor configured to detect a gas pressure parameter of a tire; a wireless receiver configured to initially be in a sleep mode, and to receive a communication protocol wirelessly after being woken up from the sleep mode; and a microprocessor configured to wake up the wireless receiver according to the gas pressure parameter.

A system includes a computer having a processor and a memory storing instructions executable by the processor to acquire a first image of a tire of a vehicle upon shutdown of the vehicle. The instructions include instruction to then, upon startup of the vehicle, and in response to determining that the tire is unmoved since the shutdown and, in response, acquire a second image of the tire. The instructions include instruction to actuate a component of the vehicle in response to determining that the first image is different that the second image.

A transmitter is mounted on each of a plurality of wheel assemblies included in a vehicle. The transmitter executes a process in accordance with a command included in a trigger signal. The transmitter includes a pressure sensor that detects the tire pressure, a transmission unit that transmits a data signal including a detection result of the pressure sensor to a receiver, a trigger reception unit that receives the trigger signal, and a controller that controls the transmitter. When the trigger reception unit receives the trigger signal including a command shifting a state of the transmitter to a standby state, the controller shifts the state of the transmitter to the standby state. Further, when the trigger reception unit receives the trigger signal including a command designating a mode while the state of the transmitter is the standby state, the controller sets the designated mode.

A tire pressure detection device includes an emitter and a receiver. The emitter is installed to a tire to detect tire pressure, and the emitter sends the tire pressure data via Bluetooth communication to the receiver. The receiver is operated by a user so as to pair the emitter on the tire that is to be checked. The receiver is an elongate part which includes an LF trigger coil connected to the front end thereof. The LF trigger coil is moved to close to the emitter and activates the emitter, such that the tire pressure is sent to the receiver. The emitter has to be paired with the receiver to send the tire pressure to the receiver.

An apparatus and method for detecting the mileage of a tyre. The apparatus includes a tyre state detector (100) and a data processor (200). The tyre state detector (100) is configured to detect and send a first identity identifier and state detection parameters of the tyre state detector (100) to the data processor (200); and the data processor (200) is configured to obtain a second identity identifier of the tyre and usage scenario information of the tyre and determine mileage data of the tyre, so as to generate and send tyre mileage detection information corresponding to the tyre. By determining the mileage data of the tyre, and establishing a correspondence relation so as to generate and send the tyre mileage detection information corresponding to the tyre, the detection of the mileage of the tyre can be realized, thereby realizing the intelligent management of the tyre.

Embodiments of the present invention relate to the field of automotive technologies, and disclose a tire location positioning method and apparatus, a tire pressure monitoring system (TPMS) receiver, a tire pressure sensor, a TPMS and an automobile. The method includes: controlling a first exciter to send a first excitation signal, and controlling a second exciter to send a second excitation signal; respectively receiving response signals that are generated according to the first excitation signal or the second excitation signal by all tire pressure sensors; performing positioning on front and rear wheels according to times when the response signals are received, to identify response signals sent by tire pressure sensors of the front and rear wheels; and performing positioning on left and right wheels according to the signal strength information, to identify response signals sent by tire pressure sensors of the left and right wheels.

A transmitter includes a condition detecting section, which detects a condition of a tire, a memory section, which stores identification information, a transmitting section, which transmits a data signal, a trigger receiving section, which receives a trigger signal transmitted from a trigger device, and a controlling section. When the trigger receiving section receives the trigger signal, the controlling section generates data corresponding to the trigger signal and causes the transmitting section to transmit the data signal, which includes the generated data. The controlling section generates encrypted data when the trigger receiving section receives a trigger signal of unmodulated waves. The controlling section generates non-encrypted data that includes the identification information when the trigger receiving section receives a trigger signal of modulated waves.

A tire air pressure detection device includes a plurality of transceivers and a receiver. The plurality of transceivers are correspondingly provided in a plurality of wheels of a vehicle. Each wheel has a tire. The receiver is attached to a vehicle body. Each of the plurality of transceivers outputs a detection signal indicative of an air pressure of the tire of the corresponding wheel. Each of the plurality of transceivers processes the detection signal, and generates a frame storing the processed detection signal as data related to the air pressure of the tire. The receiver receives the frame. The receiver detects the air pressure of the tire based on the data stored in the received frame.

Method and apparatus are disclosed for controlling vehicle TPMS sensor localization. An example vehicle includes a plurality of tire pressure monitoring system (TPMS) sensors, a communication module, and a controller. The controller is to detect an initiation event associated with the vehicle, and, in response to detecting the initiation event, determine whether first localization information is valid based on information associated with the TPMS sensors. The controller is also to initiate, via the communication module, a localization procedure at the TPMS sensors when the first localization information is not valid.

An apparatus for measuring the pressure of a two-wheeler tire comprises: an adapter component which comprises a joining mechanism to connect the apparatus to a valve of the two-wheeler tire; a valve opener to open the valve so that in a state connected to the valve pressurized air flows from the two-wheeler tire through the valve into the until the which can be connected to the adapter component; and a sensor component which can be connected to the adapter component. The sensor component comprises a pressure measurement device to measure the pressure in the apparatus and a transmitter to wirelessly transmit information corresponding to the measured pressure.
