Abstract: Disclosed is an inductive detection sensor for unlocking a vehicle opening, the sensor particularly being able to be mounted in the opening and including a printed circuit, on which an inductive coil and a management module are mounted, which module is able to detect a variation in the electromagnetic field at the terminals of the inductive coil, the sensor including a visible pressure component, which is at least partially metal, at least partially arranged in line with the inductive coil and being able to move relative to the inductive coil after a pressure is directly exerted onto the pressure component by a user, the management module being able to control the unlocking of the opening following the detection of a variation in the electromagnetic field at the terminals of the inductive coil following a movement of the visible pressure component by a user.

Abstract: A method for detecting actuation of a handle of a motor-vehicle opening panel-vehicle, including the steps of continuously generating the request to unlock signal, detecting an increase in the value of the request to unlock signal beyond a first predetermined detection threshold representative of the presence of a hand of a user on the handle, detecting a decrease in the value of the request to unlock signal below a second predetermined detection threshold representative of the user pulling on the handle, consecutively to the detection of the decrease in the value of the request to unlock signal below the second detection threshold, triggering a time counter, stopping the time counter at the end of a predetermined “confirmation time”, and validating the detection of a request to unlock the opening panel if the value of the request to unlock signal remained greater than a third predetermined threshold throughout the confirmation time.

Abstract: A device for a handle of a motor vehicle door. The device includes, integrated into the door, a primary module that supplies power by inductive coupling to a secondary module integrated into the handle. The primary module includes a primary coil and the secondary module having a secondary coil positioned facing the primary coil. The secondary coil also serves as a repeater for contactless communication between the primary module and a terminal. If the handle is retractable, the device also allows the position of the handle during its movement between a deployed position and a retracted position to be estimated.

Abstract: A presence detection device including a sensor connected to a microcontroller, the sensor including a first detection capacitor arranged in a first detection area, and a second detection capacitor arranged in a second detection area. The microcontroller is configured to recurrently repeat a phase of measuring a measurement signal by charging/discharging the first detection capacitor from/into the second detection capacitor, and to detect a presence of a user in the first detection area and/or the second detection area according to the measurement signal. Also disclosed are a motor vehicle including a detection device and a detection method.

Abstract: A device for a handle able to be deployed in relation to a motor vehicle door. The device includes a primary module integrated into the door, supplying power, through inductive coupling, to a secondary module integrated into the handle and that moves in relation to the primary module along a predetermined path when the door handle moves between a deployed position and a retracted position. An advantageous arrangement of two primary coils of the primary module and of a secondary coil of the secondary module allows the device to estimate the position of the door handle. Furthermore, the device makes it possible to establish a wireless communication link between the primary module and the secondary module.

Abstract: A device for remotely supplying power, through magnetic induction, to a secondary module able to move in relation to a primary module along a predetermined path. An advantageous arrangement of the primary coils of the primary module and of a secondary coil of the secondary module furthermore allows the device to estimate the position of the secondary module. The primary coils are arranged such that: the primary coils form respective magnetic fields oriented in the same direction along their respective axes, during the movement, the inductive coupling between the first primary coil and the secondary coil evolves in the opposite way to the inductive coupling between the second primary coil and the secondary coil, the total inductive coupling existing between the primary coils and the secondary coil is substantially constant regardless of the position of the secondary coil.
