Abstract: A method for controlling an opening of a motor vehicle by detecting movement of a target, such as user's hand or foot. The opening moveable by an actuator able to control its opening speed, and/or its degree of opening between a fully open, a fully closed, and at least one partially open intermediate position. The method including: transmitting a radiofrequency signal to at least partially reflect on the target; receiving a return signal originating from the reflection of the transmitted signal on the target; determining, based on the transmitted and return signals, at least one of movement speed, linear amplitude of movement, and/or angular amplitude of movement, relating to movement of the target relative to a determined zone of the vehicle; controlling the degree of opening and/or opening speed of the opening, using the actuator, as a function of the characteristic relating to the movement of the target.

Abstract: A system for controlling the toggling of a flush door handle of a motor vehicle from a rest position to a gripping position. The system including: a detection unit configured to transmit a radio-frequency signal, and to receive a return signal resulting from reflection of the transmitted signal by a target; and a control unit configured to perform gesture detection using the data from the detection unit, to generate an instruction to toggle from one position to another when a gesture indicating an access intention of a user is detected, and to transmit the instruction to a motor unit configured to control a position of the flush door handle.

Abstract: A method for locating a three-dimensional target with respect to a vehicle is disclosed including capturing an image of the target, and from a three-dimensional mesh of the target, and from an estimation of the pose of the target, determining a set of projecting edges of the mesh of the target in the pose. The step of determining the projecting edges of the mesh of the target includes positioning the mesh of the target according to the pose, projecting in two dimensions the mesh so positioned, scanning the projection of the mesh in a plurality of scanning rows and, for each scanning row: defining a set of segments, each segment corresponding to the intersection of a face of the mesh with the scanning row and being defined by its ends, analyzing the relative depths of the ends of the segments, the depth being the position along a third dimension orthogonal to the two dimensions of the projection, in order to select a set of end points of segments corresponding to projecting edges of the mesh.

Abstract: Method for communication between an electronic module and a sensor having a light source and being supplied by supply line, the electronic module measuring the modulations of the intensity of the current in the line. The sensor drives a gradual turning on/turning off of the light source by a first modulation of the intensity of the current such that: the light source is turned off, respectively turned on, when the intensity of the current is in a low, respectively high, state, and the light source illuminates, respectively turns off, when the duty ratio of the intensity of the current varies from the high state to the low state and vice versa. During detection, the sensor dispatches a second modulation through the light source, however if the light source is turning on (or off), this is interrupted and the intensity of current is forced to the high (or low) state.
