Abstract: A method for detecting the intention of a user to lock or unlock a motor-vehicle door with a detection device integrated into a handle. The method includes continuously measuring the resonant frequency of the detection device and successively comparing the measured resonant frequency to a first threshold representative of the approach of the user and to a second threshold, higher than the first threshold, representative of the contact of the user, the intention of the user to lock or unlock the door of the vehicle being validated only if a duration between the passage of the resonant frequency below the first threshold and the passage of the resonant frequency above the second threshold is shorter than a preset duration. An associated detection device is also disclosed.

Abstract: A device to be integrated into a handle of a vehicle door for detecting a user's intention to lock or unlock the door, with a casing therein that includes a contact detection element that detects a contact of a user's hand on the handle, where an area of contact of the handle is defined by an elastically deformable part, and the contact detection element includes a non-magnetic metal target that moves along a predetermined axis, a coil, a pre-stressed compressible element between the non-magnetic metal target and the coil, means for transmitting a movement of the elastic part to the non-magnetic metal target, and means for comparing a measured inductance of the coil and a predetermined threshold value of inductance for detecting the user's intention to lock or unlock the door.
