Embodiment Construction

[0049] The detection device D' according to the present invention is in figure 2 in the icon.

[0050] Said detection device D' takes the form of a housing integrated into the handle 10 and, as in the prior art, comprises a printed circuit 80 and at least one element for detecting the contact of the user's hand on the handle, as well as the voltage source.

[0051] However, compared with the prior art, in which the contact detection element is formed by a capacitive sensor (locking electrode E1 or unlocking electrode E2), the present invention proposes that said contact detection element 100 comprises an inductive sensor comprising, inter alia Non-magnetic metal target 40 and coil 20 .

[0052] More specifically, the housing B' includes a first portion 52' that is elastically deformable along a predetermined axis Y-Y' and includes an area 50 in contact with the handle 10, and the detection element 100 includes:

[0053] a non-magnetic metallic target 40 adapted to move alo...

Abstract

The invention relates to a piece of equipment used to detect a user's intent to lock or unlock a motor vehicle door. The equipment is integrated into a handle (10) and comprises a shell body (B'), wherein the shell body (B') comprises a first part (52) which can be deformed elastically along a preset axis (Y-Y') and comprises an area (50) in contact with the handle, a printing circuit (80), a power source voltage (Vcc) and a contact detection component (100). The contact detection component (100) comprises a non-magnetic metal target (40) which can be moved along the preset axis, a coil (20) and a capacitor (C1) which can form an oscillating circuit, a frequency device (M1) used for circuit adjustment, a prestress compressible component (30) located between the target and the coil, a device (51) used to transmit motion of the first part to the target, a device (M2) used to measure inductance (L) of the coil, a device (M3) used to compare the measured inductance and a preset inductance threshold value (Ls), and a control device (60').

Description

technical field [0001] The invention relates to a device for detecting the presence of a user and a vehicle door handle comprising said device. Background technique [0002] Currently, car door handles are equipped with devices for detecting the presence of a user. Detection of the user's presence, combined with recognition of a "hands-free" remote access control badge worn by the user, enables remote locking and unlocking of openable body sections of the vehicle. Thus, when a user wearing a corresponding electronic badge recognized by the vehicle wishes to unlock the vehicle, he approaches or touches the door handle, and then the openable body section of the vehicle is automatically unlocked. When the user approaches or presses a precise location on the door handle called the "unlock zone", the doors (or alternatively, all openable body sections) are unlocked without any further action by the user. Conversely, when a user, still wearing the requisite badge and identified ...
