A method of performing a diagnostic test on a vehicle having at least one tire includes providing the vehicle with at least one sensor configured to detect a vehicle operating characteristic, a receiver configured to receive AM signals, a notification system, and a controller in electronic communication with the at least one sensor, the receiver, and the notification system, receiving sensor data from the at least one sensor and AM signal data from the receiver, analyzing the sensor data and the AM signal data, determining whether a first condition is satisfied, and in response to the first condition being satisfied, generating a first control signal to control the notification system to generate a notification.

An auto-location system for auto-locating a wheel in a vehicle comprises: a sensor module which comprises a sensor adapted for sensing a physical property of the tire when mounted in a tire or on an inner surface of the tire of the wheel, an acquisition system adapted for determining when the part of the tire where the sensor is mounted hits the ground, and forms a contact patch with the ground, by analyzing data from the sensor, and a communication system adapted for transmitting a wireless message, in which a unique identifier is embedded, a transmit delay after the part of the tire where the sensor is mounted hits the ground.

The present application relates to a tire pressure receiver, including a main control unit, a tire pressure receiving unit, and a wireless communications unit. The wireless communications unit is configured to receive a first instruction sent by a terminal, and transmit the first instruction to the main control unit; the main control unit is configured to receive the first instruction, and update identity information of a tire pressure sensor according to the first instruction, so that the tire pressure sensor can match the tire pressure receiver; and then, the main control unit may receive, through the tire pressure receiving unit, tire pressure information corresponding to the tire pressure sensor of which the identity information is updated. In this way, a matching process is simplified, and user experience is improved. In addition, an instruction processing method is further provided.

In a method for making available data relating to the tires of a vehicle, vehicle data and/or tire data is made available by a vehicle memory unit of the vehicle, wherein the vehicle data is acquired by a sensor which is arranged in the vehicle. The vehicle data and/or the tire data have information on at least one property of the tires of the vehicle. A tire-wear probability of the tires of the vehicle is acquired as a function of the vehicle data and/or tire data. The tire-wear probability and/or the vehicle data and/or tire data are stored permanently in a memory unit arranged externally with respect to the vehicle and are made available for determining whether the vehicle requires new tires.

A system for programming a tire pressure sensor includes data processing hardware and memory hardware in communication with the data processing hardware. The memory hardware stores instructions that when executed on the data processing hardware cause the data processing hardware to (i) transmit at least one communication protocol to the tire pressure sensor, and (ii) determine a status of at least one of a power source of the tire pressure sensor or a memory of the tire pressure sensor based on the at least one communication protocol.

A tire pressure monitoring system testing tool includes a housing, an extender that protrudes from one end of the housing, and a signal emitter that disposed in a distal end of the extender. The signal emitter is configured to emit a low frequency radio frequency signal. The testing tool also includes a manually-operated activation switch that is supported on the housing and permits activation of the signal emitter. The extender is configured to provide a relatively large spacing between the switch and the signal emitter so as to permit a standing, upright user to hold the housing in one hand and to place the signal emitter at a ground-height location without requiring the user to bend at the waist or knee. In some embodiments, the length of the extender is in a range of two to twenty times the length of the housing.

An assembly (8) for a central tire inflation system includes a housing having a first end and a second end. The housing defines a fluid conduit disposed through the first and second ends. The assembly also includes one or more sensors (205, 210) having a portion disposed in the fluid conduit. Further, a power source (245) is in electrical communication with the sensor. The assembly additionally includes a kinetic energy device (220) in electrical communication with the power source. The kinetic energy device may comprise a magnet (255) sliding on a guide (265). As an alternative, the kinetic energy device may comprise a turbine (275).

The fail-safe device includes a first input for a first signal from the first sensor. The first signal indicates a first physical quantity. The fail-safe device includes a second input for a second signal from a second sensor. The second signal indicates a second physical quantity. The fail-safe device further includes a control module to verify the first signal based on the second signal and a physical relation between the first and the second physical quantities.

A tire pressure monitoring system (30) includes a data acquisition portion (101) that acquires data indicating a tire pressure and a tire temperature of the tire, from a sensor (50FL), a sensor (50FR), a sensor (50RL), and a sensor (50RR) mounted to the tire; a puncture determination portion (103) that determines whether the tire is punctured, based on a puncture determination threshold defined by a relationship between the tire pressure and the tire temperature; and a warning processing portion (105) that generates a warning indicating that the tire is punctured apart from a warning of a drop of the tire pressure when the puncture determination portion (103) determines that the tire is punctured.
