A reception control section obtains the rotation angles of wheel assemblies when receiving transmission data by a reception circuit. The reception control section divides 360°, which is the range of the possible rotation angles of the wheel assembly, into equal parts to obtain angle ranges and assigns each of the obtained rotation angles to one of angle ranges. The reception control section derives the angle range in which the number of times (frequency) the obtained rotation angles are included is a maximum value. The reception control section calculates a reception-side angle difference, which is the difference between the median values of the angle ranges in which the number of times the obtained rotation angle is included is a maximum value. The reception control section associates the ID codes with the wheel assemblies based on the correspondence between the reception-side angle difference and the angle difference between specific angles.

The present disclosure provides a method for monitoring a motion status of a vehicle, a related chip, and a system. The method includes: obtaining N acceleration values in a first axial direction collected from N times sampling and a maximum acceleration change value within a preset time period; and obtaining N acceleration values in a second axial direction collected from N times sampling and a maximum acceleration change value within the preset time period; determining whether the vehicle is in motion or in a first stationary state based on the acceleration values in the first and second axial direction; and in response to the vehicle being in the first stationary state, further determining whether the vehicle is in motion or in a second stationary state based on the maximum acceleration change values in the first and second axial direction.

A programming system includes a programming tool and a tire pressure monitoring sensor. The programming tool automatically chooses proper programming steps according to the verification code to record programs into the compatible tire pressure monitoring sensors so as to improve the shortcoming of manual choosing and recording the correct brand programs.

A vehicle determines that it is within a predefined proximity of a location for which an alternative tire pressure different from a current vehicle tire pressure has been defined. The vehicle changes a tire pressure monitoring system setting to utilize the alternative tire pressure as an alert threshold, responsive to determining that the vehicle is within the predefined proximity. Also, the vehicle determines that the vehicle has traveled more than a predefined distance from the location and, responsive to the vehicle having traveled more than a predefined distance, reverts the tire pressure monitoring system to use base settings for alert thresholds.

The invention relates to a wheel monitoring device (D) of the type comprising a housing (100) formed from a hollow core (101) containing different components including an electronic board (500) and a power supply battery (600) for said board (500), said housing (100) being positioned inside the tire and fixed to the internal portion (220) of the valve (200) fitted on the wheel, a polymer material filling in the free volume.
