Disclosed is a method for driving a processor of an electronic box mounted on a vehicle wheel, transmitting operating parameters of the wheel for implementation of a specific application by a central unit. This includes defining, for each specific application, the physical quantities liable to affect the relevance of the operating parameters, and ranges of measured values corresponding to conditions for obtaining relevant values of the operating parameters. Also included is a procedure for acquiring and transmitting the operating parameters consisting of a succession of transmission windows, during each of which the physical quantities selected for the application are measured, it is checked whether the conditions for obtaining relevant values of the operating parameters are met. If so, at least one value of each parameter is acquired and transmitted, while assigning to this value a datum attesting to the relevance of the latter, and then the transmission window is closed.

A method for determining a pivoting angle () of a wheel unit (12) mounted onto a snap-in inflation valve (10) includes the following three phases: observation of a curve representing the effect of gravity on the radial acceleration A.sub.mes of a wheel of the vehicle on a sensing axis Y which is related to the wheel unit and is not parallel to the axis of rotation of the wheel, by spectrum analysis of the gravity curve at a sampling frequency F.sub.s greater than an assumed rotation speed of the wheel, deduction of the actual rotation speed of the wheel, and determination of the pivoting angle according to the formula $\cos =\frac{\stackrel{\_}{A_{\mathrm{mes}}}}{{}^{2}R},$ where is the actual angular speed deduced from the observation of the curve, A.sub.mes is a mean value of the corrected radial acceleration, and R is a standardized radius of the wheel.

The present disclosure relates to programming tire sensors mounted to a tire of a vehicle. An identification tag device (e.g., radio frequency identification (RFID) tag) stores tire information data and/or other data that is unique to a given tire. The identification tag device can be attached to or otherwise contained within a tire-integrated sensor mount configured to support a sensor. The identification tag device transmits tire identification data and/or other data stored by the identification tag device to a sensor when the sensor is attached to or otherwise supported by the tire-integrated sensor mount. The sensor can obtain the tire identification data associated with the tire on which the sensor is mounted, thereby allowing the sensor to associate collected sensor data (e.g., pressure, temperature, etc.) with the tire identification data that is unique to the tire.

Systems and methods are described for monitoring a communicative connection with a trailer. Messages transmitted between a tire pressure management module of a trailer and a controller of a vehicle may be monitored. A notification may be triggered when the controller has not received a message from the tire pressure management module during at least a predetermined period of time.

A method of determining a status of a tyre monitoring device that includes a power supply. The method includes determining a value indicative of consumption of the power supply, determining a status of the tyre monitoring device based on the value indicative of consumption of the power supply, and providing an indication based on the determined status.

A tyre pressure detection system for abnormal vibration has an abnormal vibration detector disposed in a detection module in a tyre pressure detection system to detect any unusual acceleration of tyres. Upon detecting unusual acceleration and deciding a cause to be loosening tyre or unusual damage, a warning notice is sent to a driver. Thereby the present invention is able to provide a tyre pressure detection system with abnormal vibrations detection system.

A method, apparatus and system are disclosed in which an indication given by at least one tyre monitoring device is confirmed by input received from another source is disclosed. The method includes causing, by the control device, at least one tyre monitoring device mounted on a wheel to measure a tyre pressure and to indicate a status using an indicator provided on the tyre monitoring device; receiving, from the at least one tyre monitoring device, data representative of the status of the at least one tyre monitoring device; receiving input representative of the status indicated on the indicator of the at least one tyre monitoring device; comparing the received data representative of the status with the received input representative of the status; and taking action based on the result of the comparing.

An embodiment relates to a systems comprising a tire pressure control apparatus, a processor comprising a monitoring module and a tire pressure module, and a memory coupled to the processor, the memory comprising instructions executable by the processor to receive a route, determine an optimal tire pressure for a tire of a vehicle based on at least one of a terrain and a weather condition prior to a trip along the route, determine a tire pressure scheme prior to the trip based on the route, wherein the tire pressure scheme comprises a first tire pressure configuration for a first segment of the trip and a second tire pressure configuration for a second segment of the trip, identify a location along the route for adjusting a current tire pressure based on the tire pressure scheme, and communicate a command to the tire pressure control apparatus for adjusting the current tire pressure to the first tire pressure configuration for the first segment of the trip and the second tire pressure configuration for the second segment of the trip.

Disclosed are examples for detecting a displacement of a sensor within a tire. A baseline signal strength is compared to a measured signal strength. When a calculated comparison value (e.g., delta standard deviation) meets or exceeds a threshold value, the sensor is determined to be displaced from the expected location in the tire. When a sensor is determined to be displaced or otherwise loose from the expected location within the tire, an alert can be generated to provide notice to the vehicle driver or other entity of the issue so that the issue can then be remedied.
