Abstract: A method for detecting movement for controlling an opening of a motor vehicle including a control system for controlling the opening. The control system includes a motor, an electronic control unit, a detection sensor including a control module, a first detection element and a second detection element, with the method, which is implemented by the detection sensor, includes the steps of detecting a gesture of the user, confirming the gesture, sending a control signal to the electronic control unit for activating the motor, deactivating the second detection element, sending a control signal to the electronic control unit for stopping the motor and reactivating the second detection element if a gesture is detected in a first detection zone.

Abstract: A system that is intended to be integrated into a motor vehicle, includes a medium-range detection module for measuring a current distance relative to a portable user authentication device; and an intention sensor for detecting an intention to open and/or unlock an opening panel of the motor vehicle. The medium-range detection module has a standby state and an active state. It is able to receive control data for controlling its standby or active state, and, in response, to switch from its standby state to its active state. The intention sensor has a standby state and an active state. It is able to receive control data for controlling its standby or active state, and, in response, to switch from its standby state to its active state, with said control data depending on a detection carried out by the medium-range detection module.

Abstract: An obstacle detection system (10) intended to be installed on a motor vehicle (1) and comprising: a first UWB module (11) for transmitting an ultra-wideband radio frequency signal, called transmitted signal (S1); a second UWB module (12) for receiving an ultra-wideband radio frequency signal, called received signal (S2), with the received signal originating from the transmitted signal and comprising a first contribution (S21) originating directly from the first UWB module (11); and a second contribution (S22) being reflected on an obstacle (30) before reaching the second UWB module (12); and at least one computer (13) configured to receive data relating to the received signal (S2) as input, and to deduce time-of-flight values therefrom and then estimate a distance (D) between the obstacle and the motor vehicle; with each module from among the second UWB module (12) and the first UWB module (11) being further configured to establish a two-way exchange of radio frequency signals with a UWB fob (20) and to

Abstract: A device for a vehicle access control system, includes: a main electrode for carrying out a capacitive-type approach detection; and a transmitting and receiving antenna which is formed by a coil and is configured to transmit and receive a radiofrequency signal in order to identify a user. One turn of the coil includes: a first portion which delimits a region inside of which the main electrode is located; a second portion is offset relative to the main electrode, and at least one notch extends along one edge of the main electrode and connects the first portion and the second portion together. Each notch including two sections which are parallel to one another and connected together by a portion of the turn located at the bottom of the notch. It is thus possible to obtain a large antenna, which at the same time effectively performs a guard ring function for the main electrode.
