摘要:
The invention relates to a method of positioning sensors on wheels (200 and 300) installed coaxial at the same end of one and the same axle of a vehicle (C) comprising a receiving module (100) associated with the chassis of the vehicle, noteworthy in that it consists in positioning the sensors (210 and 310) at an angular interval of greater than or equal to ninety (90) degrees of one wheel (200) relative to the other (300) so that, when operating in displacement mode, the distance between the receiving module and the sensor varies according to the wheel rotation, and in using a link of low frequency (LF) type so that the creation of a distance between the points of emission makes it possible to vary the power of the signals received, thus rendering them distinct. The invention also relates to a device making it possible to implement the method described hereinabove. Applications: measurement and transmission of data associated with the wheels of a vehicle.

The invention relates to a method of identifying sensors (Cl, C2, C3, C4) of an information system for a vehicle (Vl) of the type that links a plurality of sensors housed in the wheels and equipped with a subassembly for transmitting the collected data to a module (100) for transmitting and receiving said collected data, which is equipped with at least one transmission/reception antenna (110), in which each axle end is fitted with twin wheels, an inner wheel and an outer wheel, each wheel accommodating an equipped sensor (Ci or Ce) of a transmission subassembly, said method being noteworthy in that it consists in varying the power of the transmission antenna (110) in such a way that the transmission field of the antenna varies and includes or excludes the sensor(s) (Ci, Ce) located within its radius of action. The invention also relates to the device for implementing the method described above. Applications: detection and transmission of parameters from vehicle tyres.

The invention relates to a method for managing data relating to an assembly forming a wheel (R) of a vehicle (C), said wheel (R) including a tyre mounted on a rim, said wheel having a measurement module (110), said tyre having an identifier made up of a radio tag (200) such as an RFID marker, said wheel being capable of having different states: mounted in which said tyre is mounted on the rim; and unmounted in which said tyre is not mounted on the rim, in which the measurement module (110) detects a pressure variation inside the tyre, and in which the storage memory of said measurement module (110) is rewritable, characterised in that said method consists of, in the event of a pressure variation, replacing the data stored in the measurement module (110) with new data from another tyre. The invention is useful in the management of data relating to tyres and wheels.

The invention relates to a method of replacing a defective sensor (100) of a surveillance system for monitoring in particular the pressure of the wheels of a vehicle (V) of the type of that comprising: - wireless sensors (100) disposed in each wheel and a receiver; a unique identifier number being assigned to each sensor (100) thus making it possible for the receiver to identify the signal. This method is noteworthy in that it consists in: removing the defective sensor (100); identifying and logging the unique identifier number of the defective sensor (100); identifying and logging the communication protocol used on the vehicle; assigning said unique identifier number to a new virgin sensor (200, 200') with neither assigned communication protocol nor assigned identifier number and simultaneously; programming the new sensor (200, 200') so that it utilizes said communication protocol. The invention also relates to the device D and the sensor 200 making it possible to implement same. Applications: detection of data available inside the wheels of a vehicle.
