The invention relates to a device (D) for fastening an electronic detection unit () for tires to a rim (J), this unit being of the type which is fastened to the valve (), which valve comprises a part () outside the rim and a part () inside the rim, said device consisting of a connection module () connected on the one hand to the inner part () of the valve () and on the other hand to a preformed receptacle () for accommodating said electronic unit (), distinguished in that said receptacle () forms an accommodation volume which is open on the tire tread side. Applications: detection unit fastened to the vehicle wheels.

Device for mechanically fastening a tyre sensor to a rim

A method of detecting the separation of an electronic module () from a vehicle on which the module is mounted. According to this method, the module () has associated with it an inductance () inseparable from the module, the inductance () and the associated module () are connected to an element of the vehicle, in the immediate vicinity of an element () made of ferromagnetic material, the current passing through the inductance () is measured (monitored), so as to detect any variation of current and, when a current variation greater than a predetermined variation threshold is detected, representative of a relative distance between the inductance () and the element made of ferromagnetic material (), there is ordered the emission of a signal indicating the separation of the module () associated with the inductance from the vehicle.
