A device for 'hands-free' unlocking/locking of a door of a motor vehicle includes a radiofrequency antenna and radiofrequency transmission/reception system to authenticate portable equipment of a user, at least one capacitive sensor to detect the approach and/or the contact of a member of the user in a predetermined zone, an electronic unit controlling the unlocking of the door, an emergency access device, and a chain. The emergency access device includes a body, a graspable pull member connected to a lock actuator and movable between retracted and deployed positions, a retention pin sliding transverse to the pull member, an electric ejector configured to control the sliding of the retention pin, and a control unit for the electric ejector adapted to control the electric ejector in two modes, the control unit controlling the electric ejector in vibration mode as a function of an authentication status of the equipment of the user.

Method for unlocking an opening element of a motor vehicle and associated unlocking device

Disclosed is an inductive position sensor including, on the one hand, a primary winding and, on the other hand, at least two secondary windings each having a plurality of turns formed of a succession of sides and produced on two opposite faces of a printed circuit board. Two pairs of two adjacent sides of each turn of at least one secondary winding form a first point directed toward a first longitudinal end and a second point directed toward a second longitudinal end of the printed circuit board, a projection on a plane of the printed circuit board of the two adjacent sides of each pair defining between them an acute projected angle.

Reduced-width inductive position sensor

The invention relates to a device for detecting the intention to unlock an opening element () of a motor vehicle with a housing () containing a support element () having a region of contact () with a handle () and being associated with an amagnetic metal target (), the device comprising a printed circuit board (), a voltage source and at least one emitter primary coil (). The support element () forms an elongated lever arm, the target () being arranged at its longitudinal free end with its other longitudinal end fixed to an anchoring point () on the housing () while being flexible toward the primary coil () under the action of the pressure from the user on the opening element handle () or frame which is transmitted to the contact region () located away from the target () by more than half of a length of the support element ().

Device for detecting by induction an intention to lock a motor vehicle door with a target on a lever arm

A vehicle opening panel emergency access device, having: a body; a graspable pull member that is able to move between: a retracted position and a deployed position; a retention pin that is designed to occupy: a locking position and a position for releasing the pull member; an electric ejector designed to control the sliding of the retention pin; a control unit for control according to two modes: an unlocking mode in which the electric ejector drives the retention pin from its locking position to its release position; and a percussion mode in which the electric ejector drives the retention pin in oscillation between its locking position and an intermediate position between the locking position and the release position.

Emergency access device for a vehicle opening panel with electrical ejector comprising a percussion mode

An emergency access device for an opening element of a vehicle, including: a body; a pull tab; a retention needle; a mechanical ejector; and an electric ejector which includes: a magnetic circuit surrounding the ferromagnetic core of the retention needle; an activation coil connected to an electric magnetization circuit, the activation coil being designed to magnetize the magnetic circuit and attract the ferromagnetic core of the retention needle; and a detection coil for detecting the position of the retention needle, the detection coil being connected to a detection circuit designed to measure the inductance of the detection coil.
