Abstract: Disclosed is an assembly of a non-magnetic and metallic target for an inductive sensor and its support, the target being flexible under pressure and under the release of the pressure in a reciprocating movement toward and away from the support. The target includes a central portion surrounded by flexible fixing tabs, a first end of which is secured to the central portion and a second end of which is fixed to the support, the fixing tabs being evenly distributed around the central portion, a first portion of each fixing tab closest to the central portion being stiffer relative to a portion of the fixing tab farthest away from the central portion.

Abstract: Disclosed is a method for detecting the approach of an object on a lateral side of a moving motor vehicle with door handles on lateral sides, each including an ultra-high-frequency antenna detecting a portable user apparatus near the vehicle and identifying it to validate hands-free access to the vehicle for the user, the method including: each antenna emitting an electromagnetic field, a first radiated power per steradian of which, in a first zone directed outside of the vehicle and defined by a first aperture angle, is greater than a second radiated power per steradian in a second, lateral zone directed toward the other antenna and defined by a second aperture angle; and, when the vehicle is moving, validating approach detection by antenna reception of an electromagnetic field emitted by the other antenna and reflected by the object, whose received power is higher than a predetermined minimum received power.

Abstract: 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.
