Definitions
- the present invention relates to an automatic locking system for a motor vehicle and in particular automatic locking of all the doors (doors, chests, tailgates ...), when the driver away from the vehicle.
- the user is provided with a means of recognition, or "identifier", which allows an on-board control unit of the motor vehicle to recognize the authorized user, when the user is in the vicinity of an opening of the motor vehicle and, generally, when the user actuates the opening handle or any external opening control device of the opening.
- identifier a means of recognition, or "identifier” which allows an on-board control unit of the motor vehicle to recognize the authorized user, when the user is in the vicinity of an opening of the motor vehicle and, generally, when the user actuates the opening handle or any external opening control device of the opening.
- This recognition is generally carried out by means of communication establishing a two-way communication between the on-board control unit and the identifier.
- the radio communication between the on-board control unit and the portable identifier is done via a device with antennas whose architecture varies from one system to another.
- devices comprising a plurality of antennas disposed at the outer walls or at the handles of the vehicle. These antennas, generally made in the form of a coil wound around a magnetic core, are fed sequentially to interrogate the identifier that can be anywhere around the vehicle. This solution works well but it is often desirable to reduce the time required for the interrogation of the identifier to be established.
- a solution has been found by the use of devices extending around the vehicle and comprising a single antenna, called a sheet antenna, made, for example, in the form of a sheet of conductive son.
- This antenna is integrated on the roof located under the roof of the vehicle and, when powered, has a homogeneous emission field around the vehicle. This makes it possible to interrogate the identifier wherever it is around the vehicle by having only one emission of field.
- the system In order to avoid an accidental locking of the vehicle, the system must check the presence of the identifier on the outside of the vehicle. This check is usually coupled with user authentication.
- the interrogation of the identifier by the on-board controller must therefore be done quickly, after closing the door, and the range of the surveillance zone covered by the device equipped with antennas, allowing this communication, must be sufficiently large and homogeneous around the vehicle so that the identifier of a user remaining close to his vehicle is always visible by the on-board control unit.
- the extent of the surveillance zone should not be too large to comply with a regulatory requirement of security against theft. Indeed, if the wearer of the identifier moves away more than two meters from his vehicle but the identifier, because of the extent of the surveillance zone, is still considered to be in an area close to the vehicle , an ill-intentioned individual can operate without worry one of the opening of the vehicle while his is already at a significant distance.
- a problem encountered when using a device with a plurality of antennas is that the sequential feeding of the antennas is not suitable for automatic locking of the vehicle. Indeed, the system will interrogate the presence of the identifier successively in the respective coverage area of each antenna. This process will take some time, and the user may be confronted when operating the handle with what is called the wall effect, that is to say, a non-opening of the actuating leaf.
- the technical problem to be solved, by the object of the present invention is to propose an automatic locking system which makes it possible to avoid the problems of the state of the art, and in particular to reduce the cost of the device in terms of the number of antennas while keeping a great flexibility of integration and a great reliability of detection.
- an automatic locking system of all the opening of a motor vehicle comprising a control unit embedded in the vehicle and able to communicate with an identifier; communication means establishing a communication between the onboard control unit and the identifier, installed in the vehicle, a device provided with antennas emitting simultaneously and whose field of two adjacent antennas combine in a positive resultant to define around the vehicle an active area, wherein the antenna-equipped device comprises only three antennas.
- the antennas transmit between 120 and 138 kHz.
- the present invention relates to an automatic locking system of all the opening of a motor vehicle, comprising a control unit embedded in the vehicle and able to communicate with an identifier; communication means establishing a communication between the on-board control unit and the identifier, installed in the vehicle, a device provided with antennas fed simultaneously and whose magnetic fields of two adjacent antennas combine in a positive resultant to define around the vehicle an active area characterized in that the antenna device comprises three antennas disposed on each side including at least one opening.
- opening of a motor vehicle, the side doors, the trunk or the tailgate.
- Active zone means the zone around the vehicle in which the intensity of the magnetic field, emitted by all the antennas, is sufficient to be detected by the identifier.
- the present invention also has particularly advantageous secondary characteristics which will be presented in the description which follows.
- FIG. 1 is a schematic top view of a motor vehicle equipped with a plurality of low frequency transmitting / receiving antennas
- FIG. 2 is a schematic top view of the active outdoor areas of the low frequency transceiver antennas.
- FIG. 3 is a schematic representation of how the total active zone is constituted
- FIG. 5 schematically represents the total active zone obtained in the case of a long vehicle according to a choice preferential integration of low frequency transceiver antennas
- FIG. 6 schematically represents the total active zone obtained in the case of a long vehicle according to a non-preferential choice of integration of low frequency transceiver antennas.
- FIG. 7 is the functional diagram for carrying out the automatic locking of the opening
- FIG. 1 illustrates a motor vehicle 1 equipped with a hands-free access device essentially comprising an on-board control unit 2 installed on the vehicle 1, and a portable identifier, not shown here, and with which the on-board control unit 2 communicates by radiofrequency wave.
- the vehicle 1 also comprises low frequency transceiver antennas including one or more low frequency transceiver antennas 3, covering the interior of the vehicle, and 3 low frequency transceiver antennas 4a, 4b, 4c covering the outside of the vehicle. and each disposed on one side (right, left, rear) of the vehicle which contains at least one opening P1 to P5.
- the low frequency transceiver antennas 3, 4a, 4b, 4c consist of coils wound around a magnetic core such as ferrite, plastoferrite, a stack of sheets of nanocrystalline alloys, etc.
- the low frequency transceiver antennas 4a, 4b disposed respectively on the right and left sides of the vehicle can be integrated in the door handles, door trim, side rods, or at any other time. another place capable of hosting a low frequency transmitting / receiving antenna.
- the low frequency transceiver antenna 4c disposed at the rear it can be integrated in the rear bumper, in the trunk or tailgate handle, on the raised stop light block, in the block. rear wiper motor, or any other location capable of accommodating a low frequency transmitting / receiving antenna.
- Figure 2 shows the outer coverage areas Z1, Z2, Z3 of each low frequency transceiver antenna 4a, 4b, 4c.
- Each coverage area Z1, Z2, Z3 corresponds to a zone where the intensity of the field emitted respectively by the antenna 4a, 4b, 4c is sufficient to be detected by the identifier.
- the low frequency waves of the present invention are chosen in the vicinity of 125 kHz, but this value may vary depending on the country and / or the embodiment, in the range 10 - 300 kHz.
- the active zones Z1, Z2, Z3 produced individually by each of the transmitting / receiving antennas 4a, 4b are simultaneously , 4c.
- the fields combine into a positive resultant and the additional active areas Z13 and Z23 are obtained.
- the total active zone Ztot is therefore the sum Z1 + Z2 + Z3 + Z13 + Z23.
- FIG. 4 shows the distances d1, d2, d3 corresponding to the respective distance between the low frequency transmitter / receiver antenna and the Ztot surveillance zone limit.
- the system will be sized to none of the distances d1, d2, d3 be greater than 2 meters (m). Indeed, the Thatcham certification requires that the active zone of detection of the identifier is less than 2 m to avoid that an ill-intentioned individual activates an opening while the user carrying an identifier has moved away at a distance reasonable but to which the identifier is still detectable.
- the second step is to verify that the identifier is no longer in the cabin using one or more antennas 3, covering the interior of the vehicle without overflowing outside, ie without it is possible to detect the identifier outside the vehicle. If the identifier is detected inside the cabin, the process stops and no automatic locking command occurs. If the identifier is not detected inside the vehicle, the process continues by checking the presence of the identifier, outside the vehicle, in an active zone Z to t. If the identifier is detected outside the vehicle in the active zone Z to t, the presence verification operation of the identifier in the active area Z to t is again carried out. This step of checking the presence of the identifier is repeated until the identifier is no longer detected in the active zone Ztot. When the identifier is no longer detected in the active zone Ztot, the system proceeds to the automatic locking of all doors.
