  • Publication number: 20200095799
    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.

  • Publication number: 20200040619
    Abstract: A method for detecting a user's intention to lock or to unlock a door of a motor vehicle, using a detection device integrated into a handle of the door, including an ultra-high-frequency antenna, one face of which is situated close to a second outer locking surface or respectively a first outer unlocking surface of the handle, an ultra-high-frequency antenna matching circuit, an ultra-high-frequency signal generator and an electronic unit. The method includes determining a parameter representative of a ratio between a power of a signal transmitted by the ultra-high-frequency signal generator to the ultra-high-frequency antenna and a power of a signal reflected from the ultra-high-frequency antenna to the ultra-high-frequency signal generator, which powers are measured beforehand, and detecting the intention to lock or respectively to unlock when the parameter is higher than or lower than a predetermined threshold.

  • Publication number: 20190383065
    Abstract: A method for detecting the approach and/or contact of a user's hand close to a motor vehicle door handle. The handle including: an electrode having a capacitance, and a device for measuring the variation in capacitance, a low-frequency antenna situated close to the electrode, the emissions of the low-frequency antenna bringing about disturbances in the operation of the device for measuring the variation in the capacitance. The method proposes that a new adaptive approach detection threshold be calculated, depending on an average of the previous measured variations in the capacitance, calculated over a predetermined time interval, the measured variations being weighted by a factor depending on a difference between each measured variation and the average of the variations calculated previously over a previous predetermined time interval, the approach detection being confirmed if the measured variation is higher than the new adaptive threshold.

  • Patent number: 8362920
    Abstract: A method and device for locating each of the wheels of a pair of twinned wheels mounted on a vehicle. Each twinned wheel is equipped with an electromagnetic receiving antenna, and these two twinned wheels are provided with elements of relative blocking rotation-wise designed to make it possible to obtain an offset by a predetermined angle (?), such that (?) is different from 0° and 180°, between the receiving antennas with which the two twinned wheels are equipped. The vehicle is equipped with a fixed source of emission of an electromagnetic signal suitable for covering an area passed through by the receiving antennas, and the electromagnetic field received by each of the receiving antennas is measured, so as to deduce, from the analysis of the time offset between the variations of the two measured electromagnetic fields, the location of each of the twinned wheels.
