This ensures that no one can start the motor vehicle while the vehicle user and his identifier is outside the vehicle. To achieve this function, the motor vehicle comprises a first antenna which emits a low frequency signal and the identifier comprises a second antenna which receives this low frequency signal. This low frequency signal accurately delimits the inner area and the area outside the motor vehicle so as to determine if the identifier is located in the passenger compartment of the motor vehicle. A disadvantage of this state of the art is that if one wants to use a method that is compatible with identifiers such as mobile phones using Bluetooth Low energy technology, the motor vehicle must have a first antenna that emits a Bluetooth Low energy signal. to communicate with said mobile phones. With such a technology, it is difficult to delimit accurately 10 different areas due in particular to spurious signals due to reflections of the signals emitted on the metal parts of the motor vehicle, reflections that exist for signals other than low frequency.

According to non-limiting embodiments, the detection method may further include one or more additional features from the following. According to a non-limiting embodiment, the threshold distance is equal to twenty centimeters plus or minus ten centimeters.
    [0005] According to one nonlimiting embodiment, the method further comprises: positioning said identifier at a reference position; calibrating the second antenna of said identifier with the first antenna during the first use of said identifier with the motor vehicle.

    [0011] BRIEF DESCRIPTION OF THE FIGURES The invention and its various applications will be better understood on reading the following description and examining the figures that accompany it. FIG. 1 represents a diagram of a system for detecting an identifier for starting a motor vehicle, making it possible to implement a method for detecting an identifier for starting a motor vehicle in a mode non-limiting embodiment of the invention; FIG. 2 represents a power regression curve applicable to an identifier of the system of FIG. 1; FIG. 3 represents a flowchart of a method for detecting an identifier for starting a motor vehicle 20 according to one nonlimiting embodiment of the invention. DESCRIPTION OF EMBODIMENTS OF THE INVENTION The identical elements, structure or function, appearing in different figures retain, unless otherwise specified, the same references. The invention relates to a method for detecting PR of an identifier Id for starting a motor vehicle V, said motor vehicle comprising a first antenna A1 and said identifier Id comprising a second antenna A2. The detection method PR is implemented by a system for detecting an identifier Id for starting the motor vehicle V. FIG. 1 illustrates said SYS detection system.
    [0012] It comprises: a first antenna Al integrated in the passenger compartment H of the motor vehicle V; an identifier Id comprising a second antenna A2; a calculator CA1 of the motor vehicle V.
    [0013] The identifier Id of the motor vehicle provides access to the motor vehicle and also to start the motor vehicle V. In non-limiting examples, the identifier Id is an electronic key, a badge, a mobile phone such as a " smartphone ".
    [0014] In a non-limiting embodiment, the identifier Id uses Bluetooth Low EnergyTM technology to communicate with the motor vehicle V, whether for access to the vehicle, that is to say to open a door of the vehicle (door or trunk), or for starting the vehicle. The procedure of access to a motor vehicle via an identifier Id being well known to those skilled in the art, it is not described here. Thus, the two antennas A1, A2 are adapted to communicate via Bluetooth Low EnergyTM technology. During the detection method PR, it is desired to determine whether the identifier Id is inside the passenger compartment H of the motor vehicle, but more particularly if it is situated at a distance less than a threshold distance ds from the first Al antenna. In a non-limiting embodiment, the threshold distance ds is equal to twenty centimeters plus or minus ten centimeters. Thus, it is determined whether the identifier Id is twenty centimeters from the first antenna Al in a non-limiting example.
    [0015] As illustrated in FIG. 1, the motor vehicle V comprises the passenger compartment H. A circle C1 inscribed in said passenger compartment H centered on the first antenna Al is defined. As can be seen, the threshold distance d s is such that it is smaller than the radius r 1 of this circle Cl. Said circle C1 defines the interior limit zone of the passenger compartment H centered on the first antenna A1. we are outside the vehicle. The circle thus corresponds to the emission of the first antenna Al at a certain power. If the first antenna Al transmits at a power higher than the corresponding power of this circle, the identifiers located outside the vehicle will be authorized to start the vehicle. Also, we define a threshold distance ds less than the radius r1 of this circle C1 to avoid starting with identifiers located outside the vehicle.
    [0016] When the identifier Id is arranged at a distance from the first sufficient antenna A1, the identifier Id is adapted to: receive a first Bluetooth low energy signal Sgl emitted by said first antenna A1; measuring the power P1 'of said corresponding received signal Sg1' by the second antenna A2; comparing said measured power P1 'with a threshold power Ps, said threshold power Ps corresponding to a threshold distance ds of said first antenna A1 which is smaller than the radius r1 of the circle C1 inscribed in the passenger compartment H of the motor vehicle V, said circle C1 being centered on said first antenna A1. On its side, said first antenna A1 of the motor vehicle V is adapted to: - transmit a first signal Sgl Bluetooth Low EnergyTM to said identifier Id at a nominal power P1; receiving, via the Bluetooth Low Energy TM communication protocol, the result of the comparison between the powers P 1 'and Ps; and transmit said result to the computer CA1 of the motor vehicle V. It will be noted that the first antenna A1 transmits at constant power P1. The nominal power P1 is the operating power of the antenna A1. As will be seen hereinafter, the power of the signal emitted by the antenna Al can be modified according to the result of the calibration described hereinafter. However, the second antennas of the identifiers, especially when these are mobile phones, have variable performance depending on the different types of mobile phones used (ie when they are manufactured by different manufacturers) but also on the inside. from the same range of phones manufactured by the same manufacturer. By different performances, it is meant that for the same signal sent by the first antenna A1 (of the same power, therefore), the different second antennas A2 will not receive the same signal power. It is therefore necessary to calibrate the second antenna A2 of an identifier Id with the first antenna Al when first used with said vehicle V. Thus, the first antenna Al is further adapted to calibrate the second antenna A2 during its first use. with the motor vehicle V. Said calibration is done when the identifier Id is positioned at a reference position Por. Thus, the identifier Id is further adapted to be positioned at said reference position Por.
    [0017] The reference position Por comprises, for example, a receptacle Re adapted to receive the identifier Id. In order to trigger the calibration, when the user presses the start button of the vehicle V, during the first use of the identifier Id with the vehicle V, a computer associated with the start button will send to the identifier Id of the vehicle V a command to the first antenna Al to emit a first calibration signal Sgc.
    [0018] Moreover, in a non-limiting embodiment, during the first use of the identifier Id with the vehicle V, so that the identifier is positioned at the reference position Por, the identifier Id is further adapted. to display on a screen Sc a Msg message (of the "Pop-Up" window type 5 in a non-limiting example) inviting the user of said identifier Id to position said identifier at the reference position Por and to trigger the calibration ( by pressing an "Ok" button in a non-limiting example).
    [0019] It will be noted that the first antenna A1 is disposed at a predetermined distance d2 from the reference position Por of the motor vehicle V. In a nonlimiting example, the predefined distance d2 is equal to ten centimeters. In another nonlimiting example, the first antenna Al is disposed at the reference position Por, i.e., the predetermined distance d2 is substantially zero. For calibration: the first antenna A1 is adapted to: transmit to the second antenna A2 a first calibration signal 20 Sgc at the nominal power PI; the second antenna A2 is adapted to: measure the power P2 'of said received reception signal Sgr received Sgc; sending said measured power P2 'to said first antenna Al; the first antenna A1 is further adapted to: compare said measured power P2 'with a theoretical power Pt corresponding to said predefined distance d2 by means of a power regression curve Cn as a function of the distance; Determining if there is an offset Off between said measured power P2 'and said theoretical power Pt; 3025641 12 If there is an offset Off, change the nominal power P1 of the first transmitted signal Sgl Bluetooth Low EnergyTM according to the offset Off or change the threshold power Ps as a function of the offset Off.
    [0020] The power regression curve Cn with respect to distance is schematically illustrated in FIG. 2. This curve is valid for all IDs that are mobile phones. On the abscissa, we find the distance (in centimeters), in ordinate, we find the power (in decibels 10 for example). It can be seen on the curve Cn that there is a first interval (between points po1 and po2) in which the curve has a steep slope and a second interval (between points po2 and po3) in which the curve has a slight slope. . The predefined distance d2 is determined so that it is in the first pot-po2 interval. In this way the measured power deviations will be more visible than in the second po2-po3 interval which will facilitate the calibration. Thus, in the example of d2 equal to ten centimeters, there will be a certain theoretical value of power Pt.
    [0021] If there is a difference Off between this theoretical value Pt and the measured value P2 ', this Off offset is taken into account. In a first non-limiting embodiment, the nominal power P1 is modified as a function of this offset Off. For example, if the power P2 'measured in the reference position Por (10 cm with respect to the first antenna Al in the example taken) is lower than the theoretical power Pt, this results in the fact that the identifier Id is considered as being at a distance higher than 10cm whereas it is actually at 10cm. It is therefore necessary to adjust the nominal power emitted by the first antenna Al according to the regression curve to make up for this difference, and in the example taken to increase the nominal power P1 so that the identifier Id receives an expected power at the reference position. .
    [0022] In a second nonlimiting embodiment, instead of modifying the nominal power P1 for transmitting the Bluetooth Low Energy signals by the first antenna A1, the threshold power Ps is modified as a function of the offset Off. The modification is made in the identifier Id, which compares the measured power P1 'with the threshold power Ps. In the example taken, the threshold power Ps is decreased. Thus, the threshold power Ps is reduced. Thus, the detection system described by SYS makes it possible to implement the detection method PR (illustrated in FIG. 3) with an identifier Id for starting a motor vehicle V, said motor vehicle comprising a first antenna A1 and said identifier Id comprising a second antenna A2, said method P comprising: transmitting by said first antenna A1 a first signal Sgl 15 Bluetooth Low EnergyTM to said identifier Id at a nominal power P1 (illustrated function TX (A1, A2, Sgl, P1)); measuring the power P1 'of said corresponding received signal Sgl' by the second antenna A2 of said identifier Id (function illustrated by RX (A2, A1, Sgl ', P1')); Comparing said measured power P1 'with a threshold power Ps (illustrated function COMP (Id, P1', Ps (ds)), said threshold power Ps corresponding to a threshold distance ds of said first antenna A1 which is smaller than the radius rl of the circle C1 inscribed in the passenger compartment H of the motor vehicle V, said circle C1 being centered on said first antenna A1; authorization of the starting of the motor vehicle V if the measured power P1 'is greater than or equal to said threshold power Ps (function shown DEM OK (CA1, V)).
    [0023] In a non-limiting embodiment, the threshold distance ds is equal to twenty centimeters plus or minus ten centimeters.
    [0024] In non-limiting embodiments, the PR method further comprises the additional steps.
    [0025] In a non-limiting embodiment, the method further comprises: positioning said identifier Id at a reference position Por (POS function (Id, Por)); the calibration of the second antenna A2 of said identifier Id with the first antenna Al during the first use of said identifier Id 10 with the motor vehicle V (function CALIBR (A2, Al)). In a nonlimiting embodiment, said first antenna A1 is disposed at a predetermined distance d2 from the reference position Por of the motor vehicle Por and the calibration comprises: the transmission by the first antenna A1 to the second antenna A2 of a first calibration signal Sgc at the nominal power P1 (TX function (Al, A2, Sgc, P1)); measuring the power P2 'of said corresponding receive signal Sgr received by said second antenna A2 (MES function (A2, P2')) and sending said measured power P2 'to said first antenna A1 (TX function (A2 , A1, P2 ')); comparing said measured power P2 'with a theoretical power Pt corresponding to said predefined distance d2 by means of a power regression curve Cn as a function of the distance (function COMP (P2', Pt, Cn)); determining if there is an offset Off between said measured power P2 'and said theoretical power Pt (function DET_OFF (P2', Pt, Off)); if there is an offset Off, change the nominal power P1 of the first transmitted signal Sg 1 Bluetooth Low EnergyTM as a function of the offset Off 3025641 15 (MODIF function (P1, Off)) or modify the threshold power Ps as a function of the offset Off (MODIF function (Ps, Off)). In a non-limiting embodiment, when the identifier 'dl is first used with the motor vehicle V, the method also comprises the display by the identifier Id on a screen Sc of a message Msg inviting the user. the user of said identifier Id to position said identifier on the reference position Por and to trigger said calibration (function DISP (Id, Sc, Msg)).
    [0026] Of course, the description of the invention is not limited to the application, embodiments and examples described above. Thus, in a non-limiting embodiment of the method, said first antenna A1 is disposed at the reference position Por, namely at the receptacle Re. Thus, in a non-limiting embodiment of the method, the method furthermore comprises the authorization of the starting of the motor vehicle V only if the identifier Id is disposed at the reference position Por of the motor vehicle V, namely on the receptacle Re.
    [0027] Thus, the described invention has the following advantages in particular: it is simple to implement; it makes it possible to determine an identifier inside the passenger compartment of a motor vehicle, and more particularly close to the antenna of the motor vehicle; it allows the use of identifiers that are mobile phones; it allows Bluetooth Low EnergyTM technology to be used not only for vehicle access but also for start-up. The same antenna is used on the vehicle side and on the identifier side. It is not necessary to use a different antenna for access and an additional antenna for starting; and 3025641 16 - it reduces costs due to the use of a single antenna to perform the two different access and start functions.
