DEVICE FOR DETECTING THE INTENT OF LOCKING OR UNLOCKING A MOTOR VEHICLE OPENING ELEMENT WITH CAPACITIVE AND INDUCTIVE SENSORS

摘要

The present invention relates to a device for detecting the intention of locking or unlocking an opening of a motor vehicle by a user. The device comprises a capacitive sensor and integrates an inductive sensor with a non-magnetic metal target moving under the action of the user's hand on the handle (18) or the frame, the target being associated with a coil (L) placed in an oscillating circuit by being connected to an inductive measuring circuit (11) detecting the intention of locking or unlocking of the opening by the user. The intention is only validated when detected by both the capacitive and inductive sensors, the target of the inductive sensor being carried by the electrode (10) of the capacitive sensor and a member (20) supporting the electrode (10) being elastically deformable under the action of the user on the handle (18) or the frame, the inductive (11) and capacitive (12) measurement circuits being independent of each other.
