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.
