    SYSTEM AND METHOD FOR REMOTELY LOCKING AND UNLOCKING A VEHICLE
    TECHNICAL FIELD OF THE INVENTION
    The present invention relates generally to the field of access to a vehicle, and more particularly to a system and a remote locking and unlocking method of a vehicle equipped with a centralized closure. Such systems allow a user to be able to lock or unlock the vehicle remotely, without the need to hold the keys of the vehicle beforehand.
    STATE OF THE PRIOR ART
    It is known remote locking and unlocking systems of a vehicle equipped with a centralized closure.
    Some systems include a central computer of the vehicle capable of controlling the central closure, and a data processing equipment connected to the central computer via a wireless communication network. This is the case, for example, with the system described in document FR 3,006,485 A1. In this system, the vehicle is equipped with a badge allowing access to the vehicle. The badge contains a vehicle identification code. A mobile communication device of a user, equipped with a contactless badge reader, can retrieve this authentication code by reading the badge. Once this code transmitted by the mobile device to the data processing equipment, as well as a specific command code, the equipment is able to send to the central computer a control signal for locking or unlocking the device. vehicle, via the communication network.
    However, such a system is compatible with very few vehicle models; indeed, it is necessary on the one hand that the on-board computer of the vehicle is adapted to communicate on a wireless communication network, and on the other hand that the data processing equipment is configured specifically for this communication, and this for each compatible vehicle model. Thus, in addition to the interoperability problem, such a solution is restrictive to use.
    [0005] Improvements in these systems exist. For example, it is known to use a system for locking and unlocking a vehicle remotely, comprising a dedicated electronic device, arranged within the vehicle and connected to the data processing equipment via a communication network without thread. The electronic device is wired directly to the vehicle's central vehicle computer. The data processing equipment is suitable for sending to the electronic device a control signal for locking or unlocking the vehicle, so that the on-board computer controls the locking or unlocking of the central locking.
    However, such a system requires complex wiring of the electronic device on the onboard computer, thus requiring a binding modification to operate on the vehicle electrical system. In addition, each wiring is specific to the vehicle model concerned. Thus, such a system offers very little flexibility of use. Indeed, the electronic device once wired on a first vehicle can not be easily reused on a second vehicle.
    SUMMARY OF THE INVENTION
    The invention described below aims to remedy all or part of the disadvantages of the state of the art and in particular to provide a remote locking and unlocking system of a flexible vehicle, simplified, and compatible with a very large number of vehicles, while not requiring any modification of the vehicle to operate.
    For this purpose, the object of the invention is a remote locking and unlocking system for a vehicle equipped with a centralized commandable closure via a remote control, the system comprising an electronic device and a data processing equipment. , the electronic device being adapted to be arranged within the vehicle and being able to be connected to the remote control via a data link, the electronic device being connected to the data processing equipment via a communication network and comprising means for communication on the data link and communication means on the communication network, in which the data processing equipment is clean, following the reception of a message associated with a command for locking or unlocking the vehicle, to transmit, on the communication network to the electronic device, a first sig the electronic device sends the remote control a second corresponding control signal, so as to lock or unlock the vehicle.
    Due to the fact that the electronic device is adapted to be connected to a remote control of the central closure via a data link and to send a control signal corresponding to a first signal transmitted by the data processing equipment, locking or unlocking the vehicle is done via the remote control. Thus, the system according to the invention adapts advantageously to all vehicles equipped with a centralized closure controllable via a remote control, in other words to a large number of vehicles. In addition, the system according to the invention does not require any complex modification of the vehicle.
    According to a particular embodiment of the invention, the locking and unlocking system further comprises an interface box connected between the electronic device and the remote control, said box being adapted to receive the second control signal and transmitting to the remote control a third control signal for locking or unlocking the vehicle.
    Such an interface box, which can translate and transmit the input-output signals of the remote control and the electronic device, provides a simple and flexible means of connecting the electronic device to the remote control.
    Advantageously, the interface box is configured to receive, from the remote control, confirmation information of the locking or unlocking of the vehicle, following the reception by the remote control of the third control signal, and to transmit on the data link to the electronic device, a confirmation signal of the execution of the locking or unlocking control of the vehicle.
    This makes it possible to provide the data processing equipment with information, via the transmission by the electronic device on the communication network of a corresponding confirmation signal. This information aims to confirm or deny the execution of the lock or unlock command by the remote control. Thus, in case of non-execution by the remote control of this lock or unlock command, the data processing equipment can advantageously re-transmit the control signal on the communication network, to the remote control.
    According to a particular technical characteristic of the invention, the data link is a wired link.
    Advantageously, the wired connection is a removable connection, for example comprising a male connector and a female connector.
    Such a feature provides a simple means to further increase the flexibility of use of the locking system and unlocking according to the invention. Thus, the only operation prior to installation of the system is to modify a pre-existing remote control of the vehicle, by welding, at certain key points of its printed circuit, an electric cable provided with the male connector or the female connector. The other connector is connected to the electronic device. The electronic device can then easily be connected to the remote control, connecting the male and female connectors together. Conversely, if the remote control further comprises a key or a start button of the vehicle engine, a user can easily, once the vehicle is unlocked, recover the remote control to start the vehicle.
    According to another particular embodiment of the invention, the locking and unlocking system further comprises a housing connected to the electronic device, the housing comprising a receiving compartment of the remote control and electromechanical actuating means d. at least one locking or unlocking button of the vehicle arranged on the remote control, said electromechanical means being adapted to receive the second control signal and to mechanically actuate said locking or unlocking button according to the value of this control signal.
    This particular embodiment of the invention avoids any prior physical intervention on the remote control, such intervention being made necessary when an electronic connection is to be provided on the remote control. This further simplifies the locking and unlocking system, no prior intervention on the remote control is expected before installation of the remote control in the system. Thus, the installation of the remote control in the system is reversible, and the remote control can advantageously be reused several times by the user, without any difficulty to do so. Similarly, a new user of the system can easily integrate the remote control of his vehicle into the system, and immediately get an operational system. The simplicity and flexibility of use of the locking and unlocking system are thus increased.
    Advantageously, the housing further comprises a lock capable of mechanically locking or unlocking the receiving compartment, said receiving compartment being mounted movably between an access opening position to the remote control, and a closed position in which the remote control is no longer accessible from outside the housing, the lock being able to lock or mechanically unlock the receiving compartment when the compartment is in its closed position.
    These characteristics make it possible to increase the robustness and the security of the system.
    According to a particular technical characteristic of the invention, the electromechanical means for actuating at least one locking or unlocking button of the vehicle comprise at least one servomotor movable between two positions, and an electronic unit for driving the movement. of the or each servomotor, the or each servomotor being provided with an actuating arm arranged opposite one or one of the button (s) for locking or unlocking the vehicle and adapted, in one of the two positions of the servomotor, to mechanically actuate said button.
    Advantageously, the or each servomotor is provided with a pressure sensor capable of measuring the pressure exerted on said locking or unlocking button of the vehicle when actuating this button by the actuator arm.
    This feature allows, in comparison with a threshold pressure value, to obtain information to confirm or deny that the support of the actuator arm button was correctly performed. Confirmation of the locking or unlocking of the vehicle is subsequently obtained. This information is reliable, compared to solutions using the detection of an end position of the arm. This information can then be supplied to the data processing equipment, via its prior transmission by the housing to the electronic device, and then sending, by the electronic device on the communication network, a corresponding confirmation signal. Thus, in the event of non-execution by the servomotor arm of this locking or unlocking command, the data processing equipment can advantageously re-transmit the control signal on the communication network, to the remote control.
    Advantageously, the electronic control unit of the movement of the or each servomotor is further connected to the lock, and is adapted to control the lock so as to lock or unlock the receiving compartment mechanically.
    These characteristics reduce the number of components in the system, so simplify the latter and reduce costs.
    Advantageously, the inside of the housing is covered with a metal film, said metal film being made of a frequency-selective magnetic shielding metal material capable of magnetically shielding the inside of the housing with respect to at least one predetermined radio frequency.
    These characteristics make it possible, when the remote control is a remote control of a central unlocking system by passive detection without contact, to avoid inadvertent unlocking of the vehicle and / or an unwanted start of the vehicle engine. Indeed, the metal film magnetically shields the housing vis-à-vis the radio frequency used by the passive detection system; in other words, the presence of the metal film prevents the propagation of the radio signal emitted by the remote control to the outside of the housing.
    According to a particular technical feature of the invention, the data processing equipment comprises a web server hosting a web programming interface, the web programming interface being adapted to transmit, on the communication network to the destination. electronic device, the first control signal for locking or unlocking the vehicle.
    Advantageously, the web server stores a table indicative of time slots for reservation of the vehicle, and the web programming interface is adapted to extract time data from the lock or unlock command of the vehicle associated with the message, to be compared. this time data to said table, and to send or not the first control signal according to the result of this comparison.
    These features make it possible to provide a service for managing access to the same vehicle by several users, for example finding an advantageous application in the context of a vehicle rental service. In addition, these features also make it possible to configure, in the web server, a time range during which the locking or unlocking control of the vehicle can actually be performed.
    [0031] Advantageously, the web programming interface exposes a web page and / or a second programming interface, said web page and / or said second programming interface providing access to the web programming interface.
    This feature allows a user to be able to transmit directly to the web programming interface, via a dedicated interface, a message associated with a lock command or unlocking the vehicle.
    Advantageously, the message associated with the vehicle lock or unlock command is a text message, including a text message according to the Short Message Service protocol, the command associated with the message being either a telephone number of a device of mobile communication having sent the text message, ie an identification number of the vehicle to be controlled, contained in the text message.
    These characteristics allow a single mobile communication device, associated with a single telephone number, to be able to control the locking or unlocking of one or more vehicle (s).
    According to another aspect, the invention also relates to a remote locking and unlocking method of a vehicle equipped with a centralized closure controllable via a remote control, the method being implemented by a locking system and unlocking device comprising an electronic device and a data processing equipment, the electronic device being arranged within the vehicle and being adapted to be connected to the remote control via a data link, the electronic device being connected to the processing equipment communication via the communication network and comprising communication means on the data link and communication means on the communication network, the method comprising the following steps: the reception, by the data processing equipment, of a message associated with a command for locking or unlocking the vehicle, The transmission by the data processing equipment, on the communication network intended for the electronic device, of a first control signal for locking or unlocking the vehicle, the reception, by the electronic device, of the first control signal for locking or unlocking the vehicle, and • sending, by the electronic device, on the data link to the remote control, a second control signal for locking or unlocking the vehicle.
    According to a particular technical feature of the invention, the locking and unlocking system further comprises an interface box connected between the electronic device and the remote control, and the method further comprises a reception step, by the interfacing box, the second control signal and a step of issuing, by the interface box to the remote control, a third control signal for locking or unlocking the vehicle.
    According to one particular embodiment of the invention, the method further comprises a step of transmitting, by the interface box, on the data link destined for the electronic device, a confirmation signal of executing the vehicle lock or unlock command, following the reception by the interface box of confirmation information of the locking or unlocking of the vehicle, transmitted by the remote control.
    This makes it possible to provide the data processing equipment with information, via the transmission by the electronic device on the communication network of a corresponding confirmation signal. This information aims to confirm or deny the execution of the lock or unlock command by the remote control. Thus, in case of non-execution by the remote control of this lock or unlock command, the data processing equipment can advantageously re-transmit the control signal on the communication network, to the remote control.

The means 60 for storing and processing data are for example formed of at least one processor associated with at least one memory.
    The remote locking and unlocking method of the vehicle 2, implemented by the locking and unlocking system 1 of FIG. 2, will now be described with reference to FIGS. 1 to 3.
    It is assumed that initially a message 32 associated with a locking or unlocking command of the vehicle 2 is issued by a user.
    More specifically, the message 32 may for example be a text message sent by a mobile communication device 48 of the user. The text message is for example consistent with the SMS (Short Message Service) protocol and is for example issued to a dedicated telephone number of a dedicated telephone server, not shown in the figures for the sake of clarity. In the case where the message 32 is a text message sent by a mobile communication device 48, the command associated with the message 32 is either the telephone number of the device 48, transmitted to the web server 34 by the telephone operator of the device 48 at the time of receipt of the message 32, a vehicle identification number 2, contained in the body of the text message. The vehicle identification number 2 is for example the registration number of this vehicle. Alternatively, the vehicle identification number 2 may be a coded digital key corresponding to the vehicle 2. The command is the telephone number of the device 48 when this telephone number is associated with a single vehicle, in this case the vehicle 2, in the correspondence table 46. The command is the vehicle identification number 2, contained in the body of the text message, when the telephone number of the device 48 is associated with several vehicles in the table of correspondence 46.
    The message 32 can also be a control command for locking or unlocking the vehicle 2 transmitted via a web page 42 or via a programming interface, for example of the REST type.
    During an initial step 70, the data processing equipment 6 receives the message 32 associated with the locking or unlocking command of the vehicle 2.
    More specifically, according to the particular embodiment of Figure 2, if the message 32 is a text message sent by a mobile communication device 48, the web server 34 receives the message 32 and verifies the presence of the number of telephone 48 of the device in the correspondence table 46. If the telephone number of the device 48 is present in the correspondence table 46, the next step 72 is triggered at the end of the initial step 70. Otherwise, the process stops.
    If the message 32 is a lock command or unlock command transmitted via a web page 42 or via a programming interface, the web programming interface 38 receives the message 32 during step 70.
    In a next step 72, the data processing equipment 6 transmits, on the communication network 10 to the electronic device 4, a first signal 28 for controlling the locking or unlocking of the vehicle 2. More specifically, according to the particular embodiment of FIG. 2, the web programming interface 38 extracts a time data item from the lock or unlock command of the vehicle 2 associated with the message 32, and then compares this time data with the table. 40 indicative of vehicle reservation time slots 2. If the result of this comparison indicates that the time data is included in a reservation slot corresponding to an identifier of the user, the web programming interface 38 transmits the first signal of control 28 to the electronic device 4, via the communication network 10. Otherwise, the process stops. In this case, if the message 32 is a text message sent by a mobile communication device 48, the data processing equipment 6 may, for example, transmit an information message to the mobile communication device 48 that has sent this message. text.
    In a subsequent step 74, the electronic device 4 receives the first signal 28 for locking or unlocking the vehicle 2. More precisely, according to the particular embodiment of FIG. 2, the means 14 on the network 10 receive the first control signal 28. At the end of the step 74, the communication means 14 then transmit the first control signal 28 to the means 24 for storing and processing data.
    In a next step 76, the electronic device 4 transmits, on the data link 8 to the remote control 3, a second signal 29 for locking or unlocking the vehicle 2. More specifically, according to the particular embodiment of Figure 2, the means 24 for storing and processing data develop the second control signal 29 from the first control signal 28 received, then transmit the second control signal 29 to the means 16 of communication on the data link 8. The communication means 16 then transmit the second control signal 29 on the wired link 8.
    Preferably, the method comprises a following step 78 during which the interface box 7 receives the second control signal 29. More precisely, according to the particular embodiment of FIG. 2, the means 56 of FIG. communication with the electronic device 4 receive the second control signal 29. At the end of step 78, the communication means 56 then transmit the second control signal 29 to the means 60 for storing and processing data.
    Preferably, the method comprises a following step 80 during which the interface box 7 transmits, to the remote control 3, a third signal 50 for locking or unlocking the vehicle 2. More specifically, according to the particular exemplary embodiment of FIG. 2, the storage and data processing means 60 elaborate the third control signal 50 from the second control signal 29 received, then transmit this third control signal 50 to the means 58 communication means with the remote control 3. The communication means 58 then emit the third control signal 50 on the wired link 8.
    At the end of step 76 or step 80, the remote control 3 receives a signal 29, 50 to control the locking or unlocking of the vehicle 2. The remote control 3 then transmits radio waves 3A to central locking of the vehicle 2, to lock or unlock the vehicle 2. Preferably, the remote control 3 then transmits on the data link 8 52 information confirming the locking or unlocking of the vehicle 2.
    Preferably, the method comprises a final step 82 during which the interface box 7 receives the information 52 confirming the locking or unlocking of the vehicle 2. The interfacing box 7 then emits, on the data link 8 to the electronic device 4, a signal 54 confirming the execution of the locking or unlocking control of the vehicle 2. More precisely, according to the particular embodiment of FIG. 2, the means 58 communicating with the remote control 3 receive the information 52, then transmit this information 52 to the means 60 for storing and processing data.

    Figures 4 to 6 illustrate a system 1 remote locking and unlocking of the vehicle 2, according to a second embodiment of the invention for which the elements similar to the first embodiment, described above with respect to the 2, are identified by identical references, and are therefore not described again.
    In this second embodiment, the system 1 no longer includes an interface box 7, but a box 90 connected to the electronic device 4. The box 90 can be electrically powered via the electronic device 4, and is intended by example to be arranged within a glove box of the vehicle 2.
    The housing 90 comprises means 56 for communication with the electronic device 4. The housing 90 further comprises a compartment 92 for receiving the remote control 3, and electromechanical means 94 for actuating at least one button 96 of locking or unlocking the vehicle 2, arranged on the remote control 3. Preferably, the housing 90 further comprises a latch 98, and means 100 for positioning and holding in place the remote control 3 within the receiving compartment 92 Still further, the housing 90 further comprises a metal film 102. The interior of the housing 90 is covered with the metal film 102, as illustrated in FIG.
    The receiving compartment 92 is movably mounted, for example in translation, between an open access position to the remote control 3, illustrated in FIG. 5, and a closed position in which the remote control 3 is more accessible from outside the case 90.
    Preferably, the housing 90 further comprises a device 103 for detecting the closure of the compartment 92, and a device for detecting the presence and the good position of the remote control 3 within the compartment 92, the latter device not shown in the figures for the sake of clarity. The device 103 is for example an electrical limit switch, comprising a first portion 103A fixed on an inner face of the housing 90, and a second portion 103B fixed on an outer face of the compartment 92, as illustrated in FIG. device for detecting the presence and good position of the remote control 3 within the compartment 92 is for example a magnetic contactor, typically a magnet.
    The electromechanical actuating means 94 are adapted to receive the second control signal 29, and to mechanically actuate at least one button 96 for locking or unlocking the vehicle 2, arranged on the remote control 3, depending on the value of this signal 29. The electromechanical actuating means 94 comprise means 60 for storing and processing data. Preferably, the electromechanical means 94 furthermore comprise at least one servomotor 104. In the embodiment of FIG. 5, the electromechanical means 94 comprise two servomotors 104. Preferably, the electromechanical means 94 further comprise a plate 105. fixing the servomotors 104, as illustrated in FIG. 6.
    The means 60 for storing and processing data are adapted to receive the second control signal 29 and to drive the servomotors 104 as a function of the value of this signal 29. The means 60 for storing and processing data are furthermore suitable for producing a feedback signal 106 for the data processing equipment 6, as will be described later. The means 60 for storing and processing data can be connected to the device 103 for detecting the closure of compartment 92, and / or to the device for detecting the presence and good position of remote control 3 within compartment 92. In this case, the information feedback signal 106 comprises, for example, information indicative of the correct closure of the compartment 92 and / or information indicative of the presence and good position of the remote control 3 within the compartment 92. means 60 for storing and processing data are for example formed of an electronic control unit associated with at least one memory.
    Each servomotor 104 is connected to the electronic unit of the means 60 for storing and processing data, inside the housing 90. Each servomotor 104 is arranged facing the receiving compartment 92, on the side of the buttons. locking or unlocking 96 of the remote control 3. Each servomotor 104 is movable between two positions, a rest position and an operating position of one of the buttons 96 for locking or unlocking the vehicle 2. Preferably, as illustrated in FIG. 6, each servomotor 104 is provided with an actuating arm 108, arranged opposite one of the locking or unlocking buttons 96 when the compartment 92 is in its closed position. The arm 108 is thus movable between a rest position and an actuating position of the button 96, in the direction of the arrow F1 as shown in FIG. 6. The arm 108 is able, in the actuating position, to mechanically actuate the button 96, so as to allow the locking or unlocking of the vehicle 2.
    Each arm 108 is for example connected to the corresponding servomotor 104 via a link fin 114 permanently attached to the servomotor 104. Each arm 108 is then removably attached to the corresponding link fin 114. This makes it possible to easily replace an arm 108 of given size and angle, by another arm 108 having a different size and / or angle (s). In addition, advantageously, the stroke and / or the speed of each arm 108 are parameterizable data within the means 60 for storing and processing data. These parameters may for example be configured remotely by a user, then transmitted to the means 60 for storing and processing data via the communication network 10. The electromechanical actuating means 94 are thus easily adaptable to the format of a remote control 3 given, to ensure compatibility of the system with any remote control format 3.
    Preferably, each servomotor 104 is further provided with a pressure sensor capable of measuring the pressure exerted on the button 96 during the actuation of this button 96 by the arm 108. Such a pressure sensor is not shown in the figures for the sake of clarity. Such a pressure sensor is for example a resistive sensor, arranged within the servomotor 104 and able to measure an electric current consumed by the servomotor 104 for the movement of the arm 108. Indeed, when the arm 108 of the servomotor 104 presses on the button 96, an electrical current draw occurs within the servomotor 104. The pressure measurement performed by the sensor is then an indirect measurement. Alternatively, the pressure sensor is for example a piezoelectric sensor and the pressure measurement performed by the sensor is then a direct measurement. Thus, confirmation information of the locking or unlocking of the vehicle 2 can be obtained, by comparison between the pressure value measured by the pressure sensor and a predetermined pressure threshold value. This lock confirmation or unlocking information can for example be integrated in the signal 106 of feedback.
    The fixing plate 105 is provided with several holes 116. Each servomotor 104 is removably attached to the plate 105, via fastening means extending through one or more holes 116. The number of holes 116 and the spacing between the holes 116 in the plate 105 are such that they make it possible to easily and precisely reposition the servomotors 104 on the fixing plate 105, in order to easily adapt the electromechanical actuating means 94 to the various remote control formats 3 and the different arrangements of buttons 96 possible. This ensures compatibility of the system with any existing remote control format 3. The spacing between two adjacent holes 116 of the plate 105 is for example substantially equal to 3 mm.
    The latch 98 is connected to the electronic unit of the means 60 for storing and processing data, as shown in FIG. 4. The latch 98 is able to mechanically lock or unlock the receiving compartment 92 when the compartment 92 is in its closed position. To do this, the latch 98 comprises for example a mechanical locking element, such as a locking rod, connected to an electric motor; these two elements are not shown in the figures for the sake of clarity. The electric motor is for example connected to the electronic unit of the means 60 for storing and processing data. The electronic unit is adapted to receive a signal 118 for mechanical locking or unlocking of the receiving compartment 92, and to control the latch 98 according to the value of this signal 118.
    An exemplary embodiment of the means 100 for positioning and holding in place the remote control 3 is shown in FIG. 5. In this example, the positioning and holding means in place 100 comprise a support plate 120 of the remote control 3.
    The support plate 120 has several holes 123, and pins inserted into all or part of these holes 123. The pins are for example removable, and can be installed or removed by a user. In addition, these pins have an adjustable height. Thus, some of these pins, which are the pins 124 shown in Figure 5, may be arranged to extend away from the plate 120 according to their maximum height. These pins 124 thus constitute delimiting pins of the remote control 3. Other pins are arranged in certain holes 123 under the remote control 3, and extend away from the plate 120 at a reduced height. These latter pins, particularly advantageous especially in the case where the remote control 3 has a curved shape, can firmly support the remote control 3.
    Such pins, thanks to their removable nature and their adjustable height, allow to give the support plate 120 a reconfigurable shape, allowing to marry precisely the shape of any remote control 3. Thus, what whatever the shape of the remote control 3, it is firmly supported by the support plate 120. This ensures a firm support of the arm 108 of each servomotor 104 on the button 96 of the corresponding remote control 3, and to avoid any movement or tilting of the remote control 3 during this support.
    In a variant not shown, the positioning and holding means in place 100 comprise a wedging plate and holding in place the remote control 3. The plate is for example provided with a recess. The plate is adapted to receive, in its recess, a portion of the remote control 3, and to hold in place the remote control 3 within the compartment 92.
    The metal film 102 is for example glued on the inside of the housing 90. The metal film 102 is made of a selective magnetic shielding metal material in frequencies. Such a material is, for example, a metamaterial of the metal-dielectric composite type. Advantageously, patterns precut periodically in the metal, such as for example slits, may be provided in the metal film 102. In addition, localized capacitive and inductive elements may be provided in the metal film 102, in addition to the patterns precut. These different patterns and elements make it possible to obtain a better frequency selectivity for the metal film 102, while inducing dimensions for the film 102 that are compatible with a case 90 intended for example to be arranged within a glove box of the vehicle. 2.
    The metal film 102 is able to magnetically shield the inside of the housing 90 vis-à-vis at least one predetermined radio frequency. In a preferred embodiment, the metal film 102 is able to magnetically shield the interior of the housing 90 with respect to a radio frequency of substantially 125 kHz. This value corresponds to a normalized value of radio frequency used in a passive detection system implementing a remote control key 3 without contact. Such a system used in a vehicle 2 comprises, in addition to the key-remote control 3, low frequency antennas integrated for example within the door handles of the vehicle and inside the latter. Such a system makes it possible to unlock the vehicle 2 and / or to start the engine of the latter when a user, bearing on him the remote control key 3, stands at a distance less than a predetermined threshold distance from the vehicle 2. the user has no manual action to be performed on the remote control for the vehicle to unlock and / or for the vehicle engine to start, because the remote control 3 periodically transmits the radio frequency signal standardized, for example with a value substantially equal to 125 kHz.
    In a variant, the material of the metal film 102 is chosen so that the latter acts as a high-pass filter, filtering all the radio frequencies lower than a predetermined threshold frequency. The predetermined threshold frequency is for example of value substantially equal to 400 MHz.
    In operation, the remote locking and unlocking method of the vehicle 2 according to the invention, implemented by the system 1 of Figures 4 to 6, is as follows.
    Initially, it is assumed that the remote control 3 is installed in the receiving compartment 92 of the housing 90. In the embodiment according to which the remote control 3 is a remote control key 3 without contact, the presence of the metal film 102 inside the housing 90 avoids inadvertent unlocking of the vehicle 2 and / or unwanted starting of the engine of the vehicle 2. Indeed, the metal film 102 magnetically shields the housing 90 vis-à-vis the frequency radio used by the passive detection system; in other words, the presence of the metal film 102 prevents the propagation of the radio signal emitted by the remote control key 3 towards the outside of the housing 90.
    The steps 70 to 76 of the method implemented by the system according to this second embodiment of the invention are identical to the steps 70 to 76 described above in connection with the method implemented by the system according to the first embodiment. realization, and therefore will not be described here in more detail.

More precisely, according to the particular exemplary embodiment of FIG. 4, the electronic unit of the data storage and processing means 60 drives one of the servomotors 104 as a function of the value of the second control signal 29. This servomotor 104 then moves from its rest position to its operating position of one of the buttons 96 for locking or unlocking the vehicle 2. In the preferred embodiment of FIG. 6, the servomotor 104 then drives the movement of the arm 108 associated with it, from its rest position to its actuating position, in the direction of arrow F1 as shown in FIG. 6. The arm 108 then mechanically actuates the button 96. At the end of this step, the remote control 3 transmits radio waves 3A to the central closing of the vehicle 2, to lock or unlock the vehicle 2. Preferably, when the second signal 29 is a vehicle lock control signal 2, the electronic unit only drives the servomotor 104 to lock the vehicle 2 if the compartment 92 has been detected in its closed position, for example via the detection device closing 103, and if the presence of the remote control 3 has been detected in the compartment 92, for example via the presence detection device and good position of the remote control 3 within the compartment 92.
    Preferably, in the exemplary embodiment in which the housing 90 comprises a latch 98, the method comprises a subsequent step in which the electronic unit of the storage and data processing means 60 receives a signal 118. The electronic unit then controls the latch 98 as a function of the value of this signal 118. Such a signal 118 for locking or unlocking control is for example transmitted by means of a latch or unlocking control signal 118. equipment 6 to the electronic device 4, via the communication network 10, then by the electronic device 4 to the means 60 for storing and processing data of the box 90. Such a signal 118 is for example derived from a message similar to the message 32 associated with a command for locking or unlocking the vehicle 2; and is for example issued in the same manner as this message 32. At the end of this step, the latch 98 locks or unlocks the receiving compartment 92. When the signal 118 is an unlocking control signal, the electronic unit driver lock 98 so that the last unlocks the receiving compartment 92. A user of the vehicle 2, having previously unlocked the vehicle 2 as described above, can then access the remote control 3 contained in the receiving compartment 92. The user can then retrieve the remote control 3, for example to start the vehicle 2.
    [00102] Preferably, the method further comprises a final step during which the means 60 for storing and processing data produce a signal 106 for feedback. The housing 90 then transmits this signal 106 on the data link 8 to the electronic device 4. The information feedback signal 106 comprises, for example, information indicative of the correct closure of the compartment 92 and / or information indicative of the presence and good position of the remote control 3 within the compartment 92 and / or confirmation information of the locking or unlocking of the vehicle 2. At the end of this final step, the electronic device 4 generates a signal 126 corresponding to the signal 106 for sending information, and transmits this signal 126 on the communication network 10, to the equipment 6.
    An advantageous application of such a system and locking and unlocking method according to the invention is for example that of an owner of a vehicle 2 wishing to lend or rent his vehicle to a user. From a text message, text message according to the SMS protocol, or a command via a web page or a programming interface, the user can unlock the vehicle 2 remotely, enter it, retrieve the key- remote control 3 in the vehicle, start the vehicle engine and operate the vehicle normally. When the user leaves the vehicle 2, he places the remote key 3 where he found it. He can then send a text message or a command via a web page or a programming interface to lock the vehicle 2.
    [00104] Thus, such an application advantageously allows the owner of a vehicle 2 to lend the vehicle to a user without physically handing him the vehicle keys. In addition, the user can access the vehicle 2 without the key of the latter, and only if the owner has authorized.
    The locking system and remote unlocking of a vehicle according to the invention offers several advantages: • the system adapts advantageously to all vehicles equipped with a centralized closure controllable via a remote control, in other words to a large number of vehicles; • the system requires no complex modification of the vehicle, only the connection of the electronic device to the remote control is to be expected; • the system does not impose any limitation on the number of callers allowed to lock / unlock the vehicle when the message associated with the command is a text message, as long as the telephone numbers of these callers are recorded in the correspondence table between phone numbers and vehicle IDs; • the system allows a single mobile communication device, associated with a single telephone number, to control the locking or unlocking of several vehicles, by filling in each text message it sends the identification number of the vehicle to be ordered.
