Method and device for identifying sensors housed in tyres
First Claim
1. A method of identifying sensors of a sensor set of an information system for a vehicle including a frame and a plurality of wheels, the sensor set including a plurality of sensors housed in the wheels, each sensor being provided with a subassembly for transmitting collected information, the method comprising:
- detecting a first signal-set received from the sensor set;
subsequently, varying power of a transmission antenna;
subsequently, detecting a second signal-set received from the sensor set;
identifying a signal present in one of the first and second signal-sets and not present in the other of the first and second signal-sets; and
associating the signal, identified in the identifying step, with one of the sensors in the sensor set.

Abstract
The invention relates to a method of identifying sensors (C1, C2, C3, C4) of an information system for a vehicle (V1) 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 tires.
