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.
