A method for detecting actuation of a handle of a motor-vehicle opening panel-vehicle, including the steps of continuously generating the request to unlock signal, detecting an increase in the value of the request to unlock signal beyond a first predetermined detection threshold representative of the presence of a hand of a user on the handle, detecting a decrease in the value of the request to unlock signal below a second predetermined detection threshold representative of the user pulling on the handle, consecutively to the detection of the decrease in the value of the request to unlock signal below the second detection threshold, triggering a time counter, stopping the time counter at the end of a predetermined 'confirmation time', and validating the detection of a request to unlock the opening panel if the value of the request to unlock signal remained greater than a third predetermined threshold throughout the confirmation time.

Capacitive sensor for a motor vehicle

A device for detecting an intention of a user to lock or unlock an opening element of a motor vehicle includes a capacitive sensor and incorporates an inductive sensor with an amagnetic metal target moving under the action of the hand of the user on the handle or the frame, the target being associated with a coil placed in an oscillating circuit being connected to an inductive measurement circuit detecting the intention of the user to lock or unlock the opening element. The intention is only confirmed when detected by both the capacitive and inductive sensors, the target of the inductive sensor being borne by the electrode of the capacitive sensor and a member supporting the electrode being elastically deformable under the action of the user on the handle or the frame, the inductive and capacitive measurement circuits being independent of each other.

A method for manufacturing a sensor having an ultra-high-frequency antenna printed on a receiving area on a first face of a printed circuit board. The first face of the board is inserted into a first housing portion with a seal and a compression element, the seal surrounding the receiving area while a first space remains free in the portion. A second face of the board is inserted into a second housing portion and the portions are pressed together, a second space remaining free. Then, polyurethane is injected into the first and second spaces, the seal preventing the polyurethane from penetrating into the receiving area.
