Abstract: A device for improving the security of a “hands-free” access system for a motor vehicle, the system comprising an identification device installed on the vehicle and able to control the locking the opening leaves of the vehicle, and at least one identifier intended to be worn or carried by a user and capable of setting up a remote exchange of data with the identification device so as to control the locking means, when the identification device has authenticated the identifier, the identification means being intended, after a locking command, to send an interrogation signal into the cabin of the vehicle and receive in response a “present” signal from each identifier still present in the cabin, wherein, when a “present” signal is received by the identification device, the identification device sends into the cabin an inhibit signal which is received and stored in memory by each identifier present in the cabin.

Abstract: An automobile vehicle equipped with a “hands-free” access and/or engine starting system controlled by a management logic subassembly and equipped with a radio receiver subassembly, which includes at the top of the vehicle's steering column a radio antenna and which converts radio signals received by said antenna into signals exploitable by said management logic subassembly to enable it, when it recognizes said signals as coming from an identification device of a predetermined user, to authorize or trigger an operation in the vehicle, said management logic subassembly, said radio receiver subassembly and said antenna being integrated in and interconnected by an electronic board, wherein this electronic board also includes a subassembly providing interfaces with “on-the-column” control and/or signaling parts mounted on the vehicle's steering column or steering wheel and/or on one or more satellite modules mounted on this steering column.

Abstract: An openable panel for a motor vehicle having a lock (3) including an opening lever, an operating member mounted on the openable panel at a distance from the lock for manual operation by a user from the outside of the openable panel. A force transmission element connects the operating member to the lock opening lever. The lock can switch from a closed condition to an open condition in response to the operation of the opening lever with the aid of the operating member. The force transmission element is in two parts connected to each other by an energy storage device. An immobilizing mechanism is provide to immobilize the second part of the force transmission element when the lock is in the locked condition and to release the second part of the force transmission element in response to an unlocking command.

Abstract: The disclosure relates to an authentication device for automobile vehicles that controls door locking and/or engine starting and is able to interchange data over a certain distance with an identifier, intended to be carried by a user, when said identifier lies within the emission/reception coverage zone of said authentication device, to enable “hands-free” vehicle access and/or engine starting when said identifier has been authenticated by said authentication device, wherein said authentication device is connected to a single antenna inside the vehicle passenger compartment and is able to emit via said antenna at least two distinct emission powers, a first emission power enabling said antenna to cover a first zone including at least part of said passenger compartment, and a second emission power greater than said first emission power enabling said antenna to cover a second zone including at least the whole of said passenger compartment and possibly a coverage zone outside said vehicle.

Abstract: An identification device for controlling locking of the opening leaves of the vehicle. The identification device is capable of remotely exchanging data with an identifier carried by a user, so as to allow access to the vehicle. The identification device is connected to a number of external antennas so as to allow dialog between identification device and the identifier. At least one pair of the external antennas have a common area of overlap, so that the identification device is able to detect the presence of an identifier in the common area of overlap when the pair of antennas receives a signal from the same identifier. Each antennas of the pair also has its own area of coverage without any mutual overlap, so that the identification device is capable of detecting the presence of an identifier in one of the two aforementioned areas of coverage.

Abstract: The communication facility for system for low frequency communication by electromagnetic coupling, comprises at least one electromagnetic field transmitting and/or receiving antenna in the form of a coil (2) disposed on a substrate board (1) serving as support, this board having a certain thickness. The coil has turns which are wound in the thickness of the substrate board so that the sensitivity of the antenna can be improved without increasing the thickness of the communication facility.

Abstract: The automobile vehicle is equipped with a recognition device (1) controlling means of locking the doors of an automobile vehicle (V). This recognition device is capable of making remote data exchanges with an identification device (17) worn or carried by a user to enable access to the vehicle when the recognition device has authenticated the identification device. The recognition device is connected to at least one antenna (2, 3, 4, 5) located in a passenger grab handle (6, 8, 10, 12) inside the vehicle.

Abstract: In this openable panel (1) comprising a lock (3), that includes an opening lever (8), an operating member (5) that is mounted on the openable panel (1) at a distance from the lock and can be operated manually from the outside of the openable panel, and a force transmission element (7) that connects the operating member to the lock opening lever, which lock can switch from a closed condition to an open condition in response to the operation of the opening lever with the aid of the operating member (5), the force transmission element (7) is in two parts (7a, 7b) connected to each other by an energy storage device (11), while an immobilizing means (12) immobilizes the second part (7b) of the force transmission element when the lock (3) is in the locked condition, and releases the second part of the force transmission element in response to an unlocking command.
