    METHOD FOR SECURING A MANEUVER TO BE APPLIED TO A
    MOTOR VEHICLE
    TECHNICAL FIELD OF THE INVENTION
    The present invention relates to a method of securing a maneuver to be applied to a motor vehicle.
    It finds a particular but non-limiting application for maneuvers that allow to park a motor vehicle.
    BACKGROUND OF THE INVENTION
    A method of securing a maneuver to be applied to a motor vehicle known to those skilled in the art includes the use by a user of the motor vehicle, a mobile terminal. This mobile terminal which is for example a mobile phone, makes it possible to remotely control the execution of a maneuver on the motor vehicle. Such a maneuver is for example the fact of parking the motor vehicle. The user who is located outside the motor vehicle can park his motor vehicle through his mobile phone. For this purpose, he starts the execution of the maneuver with his mobile terminal and to verify that it is always he who is at the controls of the maneuver, on his mobile phone he holds in one of his hands, he must make a continuous movement on the screen of the mobile phone, for example it must continuously describe a circle on the entire screen of the mobile phone for the execution of said maneuver continues to be realized.
    Note that the mobile phone includes an antenna that allows communication between said mobile phone and an antenna of the motor vehicle to perform this remote operation. Said antenna is for example disposed on the front side of the mobile phone, namely that which is directed towards the motor vehicle when the operation is performed.
    A disadvantage of this state of the art lies in the fact that the hand of the user holding the mobile phone may disrupt the antenna of said mobile phone. Indeed, the hand may distort the radiation pattern of the antenna and may therefore affect its effectiveness. This can lead to a reduction in the gain and its radiated power. Thus, this may cause communication problems between said antenna and that of the motor vehicle, and the maneuver may then be stopped during execution, regardless of the user's wishes.
    In this context, the present invention aims to solve the aforementioned drawback.
    GENERAL DESCRIPTION OF THE INVENTION To this end, the invention proposes a method of securing a maneuver to be applied to a motor vehicle, according to which said method of securing comprises: a sending by an electronic control unit of the motor vehicle; an order of activation of first data to said mobile terminal; the reception by said mobile terminal of said activation command; a display of the first data on the screen of said mobile terminal in an area opposite to said antenna zone so as to induce the realization of a continuous movement by a user on the screen of said mobile terminal at said opposite zone; a generation of second data by the mobile terminal relating to the realization of said continuous movement by said user; a comparison of said second data with an expected result dependent on the first data; if the comparison is positive, an execution by the electronic control unit of said maneuver, said steps relating to the first data and to the second data being repeated until the complete execution of the maneuver.
    Thus, as will be seen in detail below, the fact of inducing the user, who controls the maneuver via his mobile phone, to perform the continuous movement with a hand in a zone opposite to that where is placed l antenna, will force him to place the hand holding the mobile phone in the same opposite zone. The hand thus interferes much less with the antenna so that the gain of the antenna is not changed. Its radiated power is not reduced towards the vehicle and the antenna-vehicle communication is not disturbed. The maneuver is thus secure since it is not likely to be interrupted independently of the will of the user.
    According to non-limiting embodiments, the security method further comprises one or more additional characteristics among the following.
    In a non-limiting embodiment, the opposite zone is defined so that the continuous movement of the user does not modify the radiation pattern of said antenna.

    In a non-limiting embodiment, the first data comprise a point-to-point tracking test.
    In a non-limiting embodiment, the point-to-point tracking comprises an angular arrow forming a trace indication to be made with a finger.

    In a non-limiting embodiment, the first data further comprises at least one positioning point for one of the thumbs of the user.
    In a non-limiting embodiment, the point-to-point tracking comprises a circle with an arrow indicating a direction of movement.
    In a non-limiting embodiment, the display of the first data on the screen of the mobile terminal releases an intermediate zone for the display of visual information returned by the motor vehicle.
    In a non-limiting embodiment, the second data comprise coordinates of the continuous movement performed by said user.
    In a nonlimiting embodiment, the antenna zone is located on one of the sides of the mobile terminal and the opposite zone on the opposite side.
    In a non-limiting embodiment, it further comprises lighting the screen of said mobile terminal according to its inclination.
    In a non-limiting embodiment, it further comprises a display of information relating to the inclination of said mobile terminal T.
    In a non-limiting embodiment, it also comprises a preliminary step of sending a request relating to the operation to the electronic control unit of the motor vehicle.
    In a non-limiting embodiment, the maneuver is a movement maneuver of the motor vehicle between an initial position and a final position.
    In a non-limiting embodiment, the comparison of said second data with said expected result is performed by the mobile terminal.
    In a non-limiting embodiment, the mobile terminal is a mobile phone or a smartphone or a portable tablet or a connected object.
    It is also proposed a system for securing a maneuver to be applied to a motor vehicle, according to which said security system comprises an electronic control unit of the motor vehicle and a mobile terminal comprising a screen and an antenna in an antenna zone, said security system being adapted to: - send by means of said electronic control unit an order of activation of the first data to said mobile terminal; receiving by said mobile terminal said activation command; displaying by means of said mobile terminal the first data on its screen in an area opposite to said antenna zone so as to induce the realization of a continuous movement by a user on the screen of said mobile terminal at said opposite zone; generating, by means of said mobile terminal, second data relating to the realization of said continuous movement by said user; comparing the second data with an expected result dependent on the first data, said second data being generated relative to the realization of a continuous movement by a user on the screen of the mobile terminal; - If the comparison is positive, execute by means of said electronic control unit said maneuver.
    In a non-limiting embodiment, the electronic control unit and the mobile terminal are adapted to repeat said steps relating to the first data and the second data until the complete execution of the maneuver.

    DESCRIPTION OF EMBODIMENTS OF THE INVENTION
    Identical elements, structure or function, appearing in different figures retain, unless otherwise specified, the same references.
    An MTH method for securing a maneuver Mo to be applied to a motor vehicle V according to the invention is illustrated in FIG. 1.
    By motor vehicle, we mean any type of motorized vehicle.
    The motor vehicle V comprises an ECU electronic control unit and is adapted to communicate with a mobile terminal T.
    In a non-limiting embodiment, the mobile terminal T is a mobile phone. In a variant of non-limiting embodiment, the mobile phone T is a smartphone called "smartphone" in English.
    In another non-limiting embodiment, the mobile terminal T is a tablet.
    The mobile terminal T comprises: a screen E; and an antenna A located in an antenna zone Z1. In the non-limiting illustrated example in FIGS. 2 to 6, the antenna zone Z1 is located on the front side of the mobile terminal T, namely on the side which is directed towards the motor vehicle V when the maneuver Mo is carried out.
    In the non-limiting examples of Figures 2 to 6, the mobile terminal is a mobile phone or a "smartphone".
    Thanks to its mobile terminal T, a user U will be able to remotely control the launching and execution of a maneuver Mo, namely when it is outside the motor vehicle V.
    In a non-limiting embodiment, the maneuver Mo is a movement maneuver of the motor vehicle V between an initial position and a final position.
    In a first non-limiting embodiment, the maneuver Mo is a parking maneuver. Thus, for example, this maneuver Mo makes it possible to park the motor vehicle in a given parking space, the initial position being the stopped position of the motor vehicle V just before the beginning of the execution of the maneuver Mo, and the final position being the position in which the motor vehicle V is parked. This non-limiting example is taken in the following description.
    Note that the parking maneuver can be in non-limiting examples of parking in reverse or forward, and battle, or face or side.
    In a second variant of non-limiting embodiment, the maneuver Mo is an output maneuver of a parking, the initial position being the stopped position of the motor vehicle V just before the beginning of the execution of the maneuver Mo, and the final position being the position in which the motor vehicle V is when he left his parking space.
    This maneuver Mo parking or exit parking allows to park or exit a motor vehicle V while being outside the motor vehicle (ie out of his cabin), for example in case there is no no place for the driver to leave the motor vehicle when the latter is in a parking lot such as a box for example or because the adjacent motor vehicles interfere with the opening of the doors.
    Note that the initial position and the final position are known to the motor vehicle V, so that the latter knows when to stop the execution of the maneuver Mo. The motor vehicle V knows the initial position and the final position by means of sensor ( s) position and / or image sensor (s), such as video cameras or ultrasonic sensors or any other type of remote sensor. The motor vehicle V will perform the maneuver Mo with the help of these sensors.
    The security method MTH comprises the following steps illustrated in FIG.
    Note that to start the steps described below, in a non-limiting embodiment, the MTH security method comprises a preliminary step of sending (referenced 0) a request RQ by the mobile terminal T relating to the maneuver MB to the ECU electronic control unit of the motor vehicle V (illustrated in Figure 1 TX (T, ECU, RQ)). This request RQ is initiated by the user U of the motor vehicle by means of the mobile terminal T. The user U can voluntarily request, via the mobile terminal T, via an application of said mobile terminal T, the application of a maneuver Mo to the motor vehicle V.
    This request RQ makes it possible: to pair the mobile terminal T and the motor vehicle V, namely it enables the dialogue between the motor vehicle V to be initiated; to initiate the maneuver Mo to apply to the motor vehicle V; and - to start the engine of the motor vehicle V before performing said maneuver Mo if said engine is stopped.
    Thus, in the nonlimiting example taken, the user can voluntarily launch the maneuver Mo parking of the motor vehicle V or the maneuvering Mo out of a parking space. The execution of the maneuver Mo and its continuation is made thereafter by means of the steps presented below which make it possible to control via the mobile terminal T that it is always a person who controls the execution of the maneuver Mo.
    The MTH process is thus performed as follows.
    When the motor vehicle V has detected a location for parking and is thus ready to park or when it is ready to leave its parking space, in step 1) illustrated TX (ECU, T, CD, 11), the electronic control unit ECU of the motor vehicle V sends a CD activation command of the first data 11 to said mobile terminal T.
    In a non-limiting embodiment, the first data 11 comprises a point-to-point tracking test TP.
    In a first non-limiting embodiment, the point-to-point tracking test TP comprises an angular arrow F1 forming a trace indication to be made with a finger.
    In a second non-limiting embodiment, the point-to-point tracking test TP comprises: a straight double arrow F2 forming an indication of horizontal alignment to be performed with a finger; and two points P1, PT arranged on either side of said arrow F2 indicating the limits of the plot.
    In a non-limiting embodiment of this second embodiment, the first data 11 further comprises at least one positioning point P2 for one of the thumbs of a user.
    In a third non-limiting embodiment, the point-to-point tracking test TP comprises a circle C1 with an arrow indicating a direction of movement of the finger.
    Of course, in a non-limiting embodiment, the point-to-point tracking test TP may include any other geometrical shape.
    Note that in a non-limiting embodiment, the first data 11 are configured in the mobile terminal T during manufacture or parameterization of the mobile terminal T.
    In another non-limiting embodiment, the first data 11 are configured in the electronic control unit ECU of the motor vehicle V and are sent to said mobile terminal T prior to the activation command CD to the mobile terminal T.
    Note that the detection of a parking place is known to those skilled in the art and is therefore not described here.
    It should be noted that the motor vehicle is ready to leave its parking space at any time.
    In step 2) illustrated RX (T, ECU, CD, 11), the mobile terminal T receives from said electronic control unit ECU said activation command CD of the first data 11.
    In step 3) illustrated DISP (T, E, 11, Z2), following the reception of the activation command CD, the mobile terminal T displays on its screen E the first data 11 in an opposite zone Z2 to said antenna zone Z1 so as to induce the realization of a continuous movement Mv by a user U on the screen E of said mobile terminal T at said opposite zone Z2.
    In a nonlimiting embodiment, the antenna zone Z1 is located on one side of the mobile terminal T and the opposite zone Z2 on the side opposite. Thus, in the nonlimiting example illustrated in FIGS. 2 to 6, the antenna zone Z1 is located on the front side of the mobile terminal T, namely on the side that is directed towards the motor vehicle V and the opposite zone Z2 is located on the side back of the mobile terminal T, namely on the side directed towards the user U.
    The opposite zone Z2 is defined so that the continuous movement Mv (described later) of the user U to perform the maneuver Mo does not change the gain g of said antenna A and therefore does not decrease its radiated power.
    FIG. 2 illustrates the display on the screen E of the first data 11 comprising the point-to-point tracking test TP according to the first non-limiting variant embodiment, namely the angular arrow F1 forming a trace indication to be made with a finger.
    Thus, to execute the maneuver Mo and throughout the maneuver Mo, a finger of the user U must make a continuous movement Mv following the angular arrow F1 and by going back and forth on said angular arrow F1 to what the maneuver Mo is completed, namely until the motor vehicle V has reached the final position, that is to say until it has parked in the non-limiting example taken.
    Figure 3 illustrates the display on the screen E of the first data 11 which includes two possible positioning points P2, namely one for the thumb of the right hand and the other for the thumb of the left hand.
    In a non-limiting embodiment, the mobile terminal T displays on its screen E a message asking the user U to put one of his thumbs on one of the positioning points P2.
    In another non-limiting embodiment, before the display of at least one positioning point P2, the mobile terminal T displays on its screen E a message asking the user U whether he is right-handed or left-handed. Upon receiving its response, the mobile terminal T displays the appropriate positioning point P2.
    FIG. 4 illustrates the mobile terminal T of FIG. 3 on which is further displayed first data 11 comprising the point-to-point tracking test TP according to the second non-limiting variant embodiment, namely: the double straight arrow F2 forming a horizontal line indication to be made with a finger; and - the two points P1, PT disposed on either side of said arrow F2 indicating the limits of the plot.
    FIG. 5 illustrates: the display on the screen E of the point-to-point test data TP of FIG. 4; one of the thumbs of the user U positioned on the positioning point P2, in the non-limiting illustrated example, namely the thumb of the left hand; and - the handling of the mobile terminal T by the user U.
    Thus, to execute the maneuver Mo and throughout the maneuver Mo, an inch of one of his hands of the user U must be positioned on the positioning point P2 and at the same time, a finger of the other the hand of the user U must make a continuous movement Mv rectilinear following the straight arrow F2 and going back and forth on the straight arrow F2 until the maneuver Mo is completed, namely until the V vehicle has reached the final position, that is to say until it has parked in the non-limiting example taken.
    FIG. 6 illustrates the display on the screen E of the first data 11 comprising the point-to-point tracking test TP according to the third non-limiting variant embodiment, namely the circle C1 forming a trace indication to be made with a finger.
    Thus, to execute the maneuver Mo and throughout the maneuver Mo, a finger of the user U must perform with his finger a continuous movement Mv circular to follow the outline of the circle C1 in the direction indicated by the arrow and this up to that the maneuver Mo is completed, that is to say until the motor vehicle V has reached the final position, that is to say until it has parked in the example no limitation taken.
    It will be noted that the continuous movement Mv carried out by the user U makes it possible to verify that the user U is still present and that it is always he who controls the maneuver Mo the time of his execution. Thus, it is ensured that the motor vehicle is under the control of a human to perform said maneuver Mo.
    As can be seen in FIGS. 2, 4 and 6, the display of the first data 11 determines: a point of equilibrium G of the forces between the hand that holds the mobile terminal T and the finger that makes it possible to whole Mo maneuver; counter-support points brought back by hand referenced by the arrows 1, 2, 3 and / or 4 for a grip of the mobile terminal T by a user U at the opposite zone Z2 to said antenna zone Z1.
    Thus, the display of the first data 11 induces the user U to position his fingers in a particular zone which is in the opposite zone Z2.
    The arrows referenced 1 to 4 in Figure 2 indicate the handling of the mobile terminal T by the user U and thus four points against-support. In the nonlimiting example of FIG. 2, in order to perform the plot with a finger of the other hand, the user U is thus obliged to position on the edge of the mobile terminal T his thumb, his palm, his middle finger (or index) its annular respectively as indicated by the four arrows 1,2, 3 and 4 of Figure 2 to hold the mobile terminal T.
    In the nonlimiting example of FIGS. 4 and 5, in order to perform the plot with a finger of the other hand, the user U is thus obliged to position on the screen E of the mobile terminal T his thumb on the screen of the mobile terminal T and its index and middle finger on the back of the mobile terminal T to hold the mobile terminal T. The thumb is here in opposition with the index and middle finger.
    It will be noted that the counter-support points are the counter-forces of reaction that must be applied with the hand so that the mobile terminal T is stable in the hand of the user U who holds said mobile terminal T, against forces which oppose the force exerted by said user U with his finger to perform the entire maneuver Mo. It will be noted that the counter-support points thus defined induce holding by a hand of the user U which is different a natural outfit. In the case of a natural holding, the equilibrium point G is at the center of the mobile terminal T so that the hand extends over a large part of the mobile terminal T, the counter-support points defined by the arrows 1 to 4 can be in this case anywhere on the mobile terminal T, which is troublesome for the gain of the antenna A which at this time is changed. By moving the equilibrium point G, the disturbances emitted by the hand which holds the mobile terminal T on the gain of the antenna A and consequently on its radiated power have been reduced.
    Moreover, by inducing also a drawing by a finger of the user U at the opposite zone Z2 to that of the antenna A, it is also avoided that during the tracing the hand which makes said tracing also disturbs the gain of the antenna A. Thus, the drawing of a circle on a large part of the screen E of the mobile terminal T has been replaced by the drawing of an arrow F1 or the double arrow F2 or the circle C1 in a zone special. The antenna A is thus no longer masked by the hand or the fingers of the user U. There is no degradation of the radiated power of the antenna A. The function of receiving / transmitting signals with the motor vehicle V is no longer degraded. The signal transmission provided by the antenna A is thus performed under the best conditions with a good reception / transmission threshold. We are above this threshold. The range of communication with the motor vehicle V is thus not diminished. The second data 12 (described below) can be sent from the mobile terminal T to the motor vehicle V without disturbance and the maneuver Mo can thus be performed in peace. The vehicle is not likely to stop unintentionally during the Mo maneuver.
    In a non-limiting embodiment, the display of the first data 11 on the screen E of the mobile terminal T releases an intermediate zone Z3 for the display of visual information returned by the motor vehicle V. Such a zone Z3 is illustrated in FIGS. 2 to 6. Thus, if visual information is displayed on the screen E at this intermediate zone Z3, this makes it possible to keep them and not to hide them because of the display of first data 11, this would be the case if a point-to-point tracking test (eg including a circle) that appears on a large part of the E screen was used.
    In a first nonlimiting embodiment, the security method MTH furthermore comprises a lighting of the screen E of said mobile terminal T as a function of its inclination INC, namely as a function of its angle of inclination Θ with respect to the land reference. For this purpose, a positioning sensor makes it possible to provide the inclination angle Θ of the mobile terminal T. In a nonlimiting example, the positioning sensor is a gyroscope integrated in the mobile terminal T.
    In a non-limiting embodiment, if the INC inclination of the mobile terminal T is between 30 ° and 60 °, then the screen E is illuminated correctly, namely its brightness is between 100% and 20%, with 100 % the maximum level of visibility and 20% the minimum level of visibility with comfort. Below 20%, visibility will be too bad for the user.
    It should be noted that the maximum value of personal visibility (corresponding to the brightness of 100%) is defined by the user as being his own level of comfort. This maximum value of personal visibility is parameterized by the user in the mobile terminal T.
    This privileges the reading of the data displayed on the screen E when the mobile terminal T is positioned between 30 ° and 60 °.
    In a non-limiting embodiment, if the inclination INC of the mobile terminal T is between 30 ° and 60 °, then the brightness is 100%.
    In another variant of non-limiting embodiment, if the inclination INC of the mobile terminal T is at 45 °, then the screen is illuminated optimally, namely its brightness is in a non-limiting example equal to 100% and as soon as the inclination is different from 45 °, the luminosity is gradually decreased until nothing is seen if the inclination INC is greater than 60 ° or less than 30 °.
    In a nonlimiting embodiment, if the INC inclination of the mobile terminal T is greater than 60 ° (the mobile terminal T tends to be upright) or less than 30 ° (the mobile terminal T tends to be flat), the Screen E is less well lit, it is obscured, namely its brightness decreases and in a non-limiting example, is less than 20%.
    Enslaving the brightness on the tilt angle of the mobile terminal T adds a constraint to the user U which in order to read the data displayed on the screen E must tilt its mobile terminal T in the correct range of values. namely here between 30 ° and 60 °. This makes it possible to position the mobile terminal T so that its antenna A communicates correctly with the antenna B of the motor vehicle V. In this case, the radiated power of the antenna A is satisfactory.
    In a second non-limiting embodiment, the security method MTH furthermore comprises the display of information DATJNC relating to the inclination INC of said mobile terminal T, namely its angle of inclination Θ with respect to the earth reference . This allows the user U to tilt his mobile terminal T so as to have a radiated power from the antenna A sufficient for the latter to communicate correctly with the motor vehicle V.
    Indeed, if the mobile terminal T is badly inclined, the signals sent by the antenna A lose power.
    In a non-limiting embodiment, if the inclination INC of the mobile terminal T is between 30 ° and 60 °, the radiated power of the antenna A is sufficient to have good communication. In a non-limiting embodiment variant, if the inclination INC is 45 °, the communication is optimum. For this purpose, in a non-limiting embodiment, the mobile terminal T comprises an inclination indicator IND. In a non-limiting example, this IND inclination indicator is a gauge. The inclination information DATJNC is therefore a gauge.
    This gauge displays a percentage of communication between the antenna A and the motor vehicle V, and furthermore: passes from the green color to the red color when the inclination INC of the mobile terminal T is no longer correct to have a power sufficient radiation; goes from the red color to the green color when the inclination INC of the mobile terminal T is correct to have a sufficient radiated power.
    It will be noted that there is a pre-calibration of the inclination as a function of the radiated power of the antenna A used.
    Of course, the first embodiment with the illumination and the second embodiment with the inclination display can be combined.
    In step 4), illustrated GEN (T, 12 (Mv)), the mobile terminal T generates second data 12 relating to the realization of said continuous movement Mv by said user U.
    In a non-limiting embodiment, the second data 12 comprise coordinates of the continuous movement Mv performed on the screen E by said user U, namely the coordinates of the plot made by the human user U.
    Thus, the mobile terminal T continuously records the coordinates of the plot made by the user U. It thus records the movement of the finger of the user U.
    In the first non-limiting embodiment of the point-to-point tracking TP, the coordinates recorded are those of the trace made by the finger on the angular arrow F1, namely the round trips along said arrow on the screen E.
    In the second non-limiting embodiment of the point-to-point tracking TP, the coordinates recorded are those of the trace made by the finger on the straight arrow F2, namely the round trips along said arrow. In the third non-limiting embodiment of the point-to-point tracking TP, the recorded coordinates are those of the trace made by the finger on the circle C1, namely the circular iterations.
    In step 5) illustrated COMP (12, Fi1 (11)), said second data 12 are compared with an expected result FM depending on the first data 11.
    Thus, the plot actually made by the user U is compared with a theoretical plot corresponding to the point-to-point test tracking to be performed, the theoretical plot being the expected result of FM point-to-point test monitoring.
    The second data 12 are thus validated or invalidated.
    The second data 12 may, for example, be invalidated if: in the example of a point-to-point tracking test, an inaccurate or too imprecise plot has been made by the user U. The user U has thus not do the right thing; or - the transmission of said second data 12 does not succeed.
    In a non-limiting embodiment, the comparison is performed by the mobile terminal T.
    Thus, the mobile terminal T performs the so-called dead man function called in English "dead man" as a whole, namely it ensures that the finger is always in motion and is well drawn to verify that the maneuver is always under the control of the user U.
    The mobile terminal T regularly sends the result R2 of the comparison to the electronic control unit ECU (step not shown). In a non-limiting embodiment, the result R2 of the comparison is sent at a frequency of 30 milliseconds to ensure real-time control.
    The result R2 of the comparison is either a valid state or an invalid state.
    In a non-limiting embodiment, the sending of the result R2 is carried out if a hands-free identifier ID of the motor vehicle V is active, namely whether it is recognized by said motor vehicle V.
    Such ID handsfree ID allows to perform a so-called hands-free function, namely to automatically open an opening (door, trunk, tailgate) of the motor vehicle V without user action.
    Such ID handsfree identifier is recognized by the motor vehicle V if it is located near said motor vehicle V, namely between 2 and 4 meters. Indeed, the identifier ID communicates with said motor vehicle V at low frequency.
    Thus, the sending of the result R2 (by the Bluetooth communication protocol for example) is conditioned by the activation of the hands-free identifier ID, which makes it possible to be sure that the user U is at a distance of 2 to 4 meters, namely at a distance to which he intends to order a maneuver Mo to apply to the vehicle V and that the motor vehicle V is within range of his view. It is thus sure that the user U is not 10 meters for example and that he "plays" with the application on his mobile terminal T which allows to start the maneuver Mo.
    It will be noted that the results R2 of the successive comparisons are numerical data. They will be modified by a transmission stage to be transmitted via the antenna A to the antenna B of the motor vehicle V. The transmission stage (not shown) comprises in a manner known to those skilled in the art in particular: digital-to-analog converter for converting digital data into low-frequency analog data (in the order of a few hundred kilohertz); a frequency transposition unit for switching from the low frequency to the frequency of the antenna A (namely the Bluetooth® frequency, ie 2.4GigaHerz in a non-limiting example); a signal amplifier for amplifying the analog data; the antenna A of the mobile terminal T for: converting the analog data into electromagnetic signals; sending the electromagnetic signals to the antenna B of the motor vehicle V, said electromagnetic signals being rendered in digital data comprehensible by the electronic control unit ECU of the motor vehicle V via another stage of realization inverse to the transmission, called the stage of reception, vehicle side V.
    In another non-limiting embodiment, the ECU electronic control unit can perform the comparison with the expected result R1 dependent on the first data 11. In this case, the second data 12 are sent by the mobile terminal T to the unit electronic control unit so that the latter can perform the comparison.
    In step 6) illustrated EXE (ECU, Mo), if the comparison is positive, the electronic control unit ECU executes said maneuver Mo, said steps relating to the first data 11 and the second data 12 being repeated until the complete execution of the Mo maneuver
    Note that when the comparison described above is performed by the mobile terminal T, the steps relating to the first data 11 and the second data 12 are repeated in the mobile terminal T until the complete execution of the maneuver Mo.
    If the comparison is positive, namely the result R2 of the comparison is a valid state, the second data 12 are validated, namely the actual plot is equal to the theoretical plot, and the maneuver Mo (here parking the motor vehicle V in the non-limiting example taken) is executed and continued as long as the comparison is positive.
    If the comparison is negative, ie the result R2 of the comparison is an invalid state, the second data 12 is invalidated, ie the actual plot is different from the theoretical plot, and the maneuver Mo, (here parking the motor vehicle V in the non-limiting example taken), is not executed or is not continued. So, even if it started, as soon as the comparison becomes negative, then the Mo maneuver is stopped.
    When the continuous movement Mv stops, the execution of the maneuver is stopped. Thus, if a moving obstacle (a person, another motor vehicle, an animal, etc.) approaches the motor vehicle V, it is sufficient for the user U to stop the drawing so that the motor vehicle stops.
    It will be noted that the steps relating to the first data 11 and the second data 12, namely the generation of the first data 11, their display, the generation of the second data and their comparison, are repeated until the complete execution of the maneuver Mo .
    Thus, the method MTH described above is executed by a system for securing a maneuver Mo to be applied to the motor vehicle V.
    This system is described in FIG. 7. It comprises: the electronic control unit ECU of the motor vehicle V; and the mobile terminal T.
    The mobile terminal T and the motor vehicle V are adapted to communicate with each other via antennas A and B respectively. The electronic control unit ECU of the motor vehicle V is adapted to: - send a CD activation command of the first data 11 to a mobile terminal T comprising a screen E and an antenna A located in an antenna zone Z1 (function illustrated on Figure 7 TX (ECU, T, CD, 11)); if the comparison is positive, execute said maneuver Mo (function illustrated in FIG. 7 EXE (ECU, MB)).
    The mobile terminal T comprises a touch screen E and said antenna A in said antenna zone Z1.
    In a non-limiting embodiment, the antenna A communicates with the motor vehicle V, in particular with one of its antennas B via the WIFI ™ or Bluetooth® protocol.
    Note that for a maneuver parking or parking exit, the user is about 2 to 4 meters from his motor vehicle V.
    In a non-limiting embodiment, the theoretical radiated power of the antenna A is 15 meters.
    Note that because of its environment, the range of the antenna A is not optimum. Indeed, its radiated power is reduced due in particular to the phenomena of local fading of signal, called in English "fadding", due to reflections of the signals emitted by the antenna A on obstacles in its environment such as walls by example. Therefore, its range can in practice be limited to 7 meters in a non-limiting example instead of 15 mothers for a theoretical scope in a non-limiting example.
    When the antenna A of the mobile terminal T communicates with the antenna B of the motor vehicle V, its radiation pattern cooperates with that of the antenna B. Or the radiation patterns are not homogeneous, when the vehicle performs the maneuver Mo, he can turn. The cooperation between the two diagrams can thus vary and cause a variation of the range of the antenna A. The latter can thus become less than 7 meters in the given non-limiting example.
    The fact that the user's hand no longer disturbs the antenna A or does not further reduce its range, up to 1 to 1.5 meters for example (while the user U is between 2 and 4 meters of the motor vehicle). Thus, the range of the antenna A, even reduced because of its environment and the variation in the cooperation between the two radiation patterns of the two antennas A and B, remains sufficient for the maneuver Mo runs smoothly.
    The mobile terminal T is adapted to: - receive from said electronic control unit the activation command CD of the first data 11 (function illustrated in FIG. 7 RX (T, ECU, CD, 11); - display the first data 11 on its screen E in an opposite zone Z2 to said antenna zone Z1 so as to induce the realization of a continuous movement Mv by a user U on the screen E of said mobile terminal T at said opposite zone Z2 (illustrated function in FIG. 7 DISP (T, E, 11, Z2)); - generating said second data 12 relating to the realization of said continuous movement Mv by said user U (function illustrated in FIG. 7 GEN (T, 12 (Mv)) ).
    In the nonlimiting embodiment illustrated, the mobile terminal T is further adapted to compare second data 12 with an expected result R1 depending on the first data 11, said second data being generated relative to the realization of a continuous movement Mv by said user U on the screen E of the mobile terminal T (function illustrated in FIG. 7 COMP (12, R1 (11)).
    In a non-limiting embodiment, the mobile terminal T is further adapted to send a request RQ relating to the maneuver Mo to the electronic control unit ECU of the motor vehicle V (function illustrated in FIG. 7 TX (T, ECU , RQ)).
    The mobile terminal T comprises a processing unit PR to perform the functions mentioned above. The processing unit PR comprises one or more processors.
    In a nonlimiting embodiment, the electronic control unit ECU and the mobile terminal T (in particular its processing unit PR) are adapted to repeat said steps relating to the first data 11 and the second data 12 to the first data item. complete execution of the Mo maneuver
    Of course, the description of the invention is not limited to the embodiments described above.
    Thus, the method may be applicable to any motorized vehicle in which a maneuver Mo would be controlled via a unit outside said motorized vehicle, such as in non-limiting examples of remote controllable devices such as models or drones.
    Thus, instead of performing the point-to-point tracking test TP with one of his fingers, the user U can use a stylus.
    Thus, the display of first data 11 in the opposite zone Z2 other than an arrow or a double arrow or a circle can be performed.
    Thus, the invention described has the following advantages in particular: it does not modify the radiation pattern of the antenna, in other words it does not modify the gain of the antenna in all directions. The antenna is thus not disturbed during the transmission / reception of signals; it avoids that the motor vehicle V stops untimely in the middle of the maneuver Mo independently of the will of the user who controls the maneuver Mo without changing the antenna A to increase its performance for example; it makes it possible to remain above the threshold of reception / transmission of signals by the antenna A; it makes it possible to apply a maneuver Mo to the motor vehicle V in a secure manner, without modifying the performance of the antenna A and without changing the antenna A. It is therefore inexpensive to implement; - it is simple to implement; - It allows without changing its operation or its performance to use a mobile terminal T to control the launch and execution of a maneuver and perform the function of "dead man".
