Description

Title of the invention: Motor vehicle for displaying part of a pattern and method for displaying at least a portion of a pattern. Technical field of the invention

[0001] The invention relates to a motor vehicle. The invention also relates to a method for displaying at least a portion of a pattern. Technical background

[0002] Prior art is already known of motor vehicles comprising display means, such as a screen, for displaying a pattern, for example an image or an alert, to persons located outside the vehicle. US patents 11373211B2 and 20210362598A1 describe, for example, motor vehicles comprising screens for displaying patterns.

[0003] Document US11373211B2 describes in particular the display by several vehicles of different parts of a pattern that has been assigned to them when they enter a predetermined geographical area.

[0004] The rendering of the patterns displayed using this method is generally unsatisfactory. Indeed, the vehicles to which parts have been assigned are sometimes too far apart or too close together for the pattern they display together to be intelligible. People outside the vehicle observe a distorted pattern which can, depending on the circumstances, lead to safety problems, for example, when the pattern to be displayed is a warning signal. Summary of the invention

[0005] The invention is intended in particular to overcome the aforementioned disadvantages.

[0006] To this end, the invention relates to a motor vehicle comprising: - at least one optical unit for displaying a first part of a pattern, - means for communicating with another motor vehicle and / or a communication infrastructure, the other vehicle being intended to display a second part of the pattern, the communication means being intended to receive at least one piece of information from the other motor vehicle and / or the communication infrastructure, - control means for modulating the display of the first part of the pattern by the optical unit according to the information received from the other motor vehicle and / or the communication infrastructure, this information being related to at least one of the following: a geographical position of the motor vehicle, a geographical position of the other motor vehicle, and a position relative of the motor vehicle and the other motor vehicle in relation to each other.

[0007] It is understood that it is thus possible to modulate the display of the portion of the pattern shown according to the respective absolute positions of the motor vehicle and / or according to the relative positions of the vehicles with respect to each other. In particular, the invention makes it possible to modify in real time and continuously the first and second parts of the patterns displayed respectively by the motor vehicle and the other motor vehicle according to their respective positions, in order to ensure that the displayed portion of the pattern is intelligible. Specifically, it can be provided that the pattern is projected onto a virtual plane and that the positions of the motor vehicle and the other motor vehicle in this virtual plane determine respectively the first and second parts of the pattern displayed by these motor vehicles.

[0008] The communication means enable motor vehicles to communicate with each other or with a communication infrastructure information relevant to modulating the pattern parts to be displayed by each motor vehicle. In addition to information relating to the positions of the motor vehicles, this information may relate, without limitation, to the nature of the pattern part to be displayed, or to the dimensions of the pattern part to be displayed.

[0009] Communication with a communication infrastructure refers to communication between a motor vehicle and any other structure (commonly called Vehicle-to-Everything or V2X communication). This includes, in particular, in addition to vehicle-to-vehicle (commonly abbreviated V2V) communication, vehicle-to-device (V2D or Vehicle-to-Device) communication, vehicle-to-infrastructure (V2I) communication, and vehicle-to-network (V2N or Vehicle-to-Network) communication. For example, this communication infrastructure can typically be expected to send instructions to motor vehicles based on their geographical positions in order to determine which part of the pattern they should display.

[0010] The control means use the information exchanged between the motor vehicle and the other vehicle and / or the communication structure to modulate the display of the pattern portion. It is understood, for example, that this modulation may consist of a modification of the nature or size of the pattern portion to be displayed. It is thus possible to ensure synchronized display in time and space of the different parts of the pattern in order to obtain a reconstructed pattern that is intelligible and of satisfactory visual quality for a person observing the pattern. In particular, the synchronization is such that a person viewing the pattern has an impression of continuity between the different parts of the pattern displayed by the vehicles. different vehicles, even if portions of the pattern are missing due to the space between the optical units of the different vehicles. The control means include, for example, an electronic control unit capable of receiving and processing information received via communication means from another vehicle and / or from a communication infrastructure, the electronic control unit being capable of commanding, for example, the optical unit to modify the portion of the pattern to be displayed.

[0011] The invention may include one or more of the following optional features, taken alone or in combination:

[0012] - The control means include synchronization means intended to modulate a display of the first part of the pattern by the optical unit according to the information received from the other motor vehicle and / or from the communication infrastructure so as to synchronize the display of the first part of the pattern with a display or projection of the second part of the pattern in order to display at least a portion of the pattern.

[0013] - The optical unit includes a screen for displaying the first part of the pattern.

[0014] - The optical unit is capable of displaying a holographic image.

[0015] - The optical unit is capable of displaying a first version of the first part of the pattern from a first viewpoint and a second version of the first part of the pattern, different from the first version of the first part of the pattern, from a second viewpoint.

[0016] - The motor vehicle further includes means for estimating a probability of future movement of the motor vehicle or other motor vehicle, the control means being configured to modulate a display of the first part of the pattern by the optical unit according to an estimate of a probability of future movement provided by the means for estimating a probability of future movement.

[0017] The invention also relates to a method for displaying at least a portion of a pattern by at least two motor vehicles as described above, in which: a) A first motor vehicle displays a first part of the pattern, b) A second motor vehicle displays a second part of the pattern, c) The display of the optical unit of at least one of the first and second motor vehicles is modulated according to at least one piece of information exchanged between the first and second motor vehicles and / or according to at least one piece of information exchanged between the first or second motor vehicle and a communication infrastructure, this information being related to at least one of the following: a geographical position of the first motor vehicle, a geographical position of the second motor vehicle, and a relative position of the first and second motor vehicles with respect to each other, so as to synchronize the display of the first and second parts of the pattern with respect to each other and thus display at least a portion of the pattern.

[0018] It is thus possible to ensure that a pattern is displayed synchronously in time and space by at least two different vehicles, in particular through the sharing of information relating to the positions of the first and second motor vehicles. Therefore, a person observing the parts of the pattern displayed by the first and second vehicles will have an impression of continuity of the displayed pattern, despite the potentially variable distance between the vehicles.

[0019] As previously stated, in a non-restrictive manner, the information exchanged between the first and second motor vehicles relates, for example, in addition to information relating to the positioning of the motor vehicles, to the nature of the part of the pattern to be displayed or to the dimensions of the part of the pattern to be displayed.

[0020] The invention may include one or more of the following optional features, taken alone or in combination:

[0021] - The information exchanged relates to the first and second parts of the pattern that The first and second motor vehicles are intended for display.

[0022] - The modulation of the display of the optical unit of at least one of the first and second motor vehicles consists of ordering a modification of the part of the pattern that is displayed by the respective optical units of the first and / or second motor vehicles.

[0023] - The modulation of the display of the optical unit of at least one of the first and second motor vehicles consists of ordering a movement of at least one of the first and second motor vehicles.

[0024] - The modulation of the optical unit's display is performed continuously over time as long as the display of at least a portion of the pattern is desired.

[0025] - The first part of the pattern and the second part of the pattern to be displayed are determined based on the respective geographical positions of the first and second motor vehicles in relation to a virtual plane into which the pattern is projected.

[0026] - When at least one of the first and second motor vehicles leaves the field from the virtual plane, the display of the optical unit of this at least one of the first and second motor vehicles is modulated so as to display a part of a pattern created by means of pattern part generation on the basis of the pattern.

[0027] - When a planned display time of the pattern, called the original pattern, is exceeded, one module the display of the optical unit of at least one of the motor vehicles of in order to display parts of a new pattern created by means of generating a new pattern based on the original pattern.

[0028] - When a latency exceeding a predetermined threshold is detected for the exchange information exchange between the first and second motor vehicles and / or between the first or second motor vehicles and the communication infrastructure, the display of the optical unit of at least one of the first and second motor vehicles is modulated so as to display pattern parts created by pattern part generation means on the basis of at least one piece of information previously exchanged between the first and second motor vehicles and / or between the first or second motor vehicles and the communication infrastructure and on the basis of pattern parts previously displayed by the optical units of the first and second motor vehicles.

[0036] Figure [1] shows a first motor vehicle 11 and a second motor vehicle 21 according to an embodiment of the invention.

[0037] Each motor vehicle 11, 21 comprises an optical unit 2 including, in this case, a screen 4 located on the rear face of the motor vehicle 11, 21 ([Fig. 1]). More specifically, in this case, the screen 4 is located on the respective rear windows of the first and second motor vehicles 11, 21. In other embodiments, the optical unit 2 may also comprise several screens 4 or any other display means. According to other embodiments In implementation, the screen(s) 4 may be located elsewhere on the motor vehicle 11,21, for example on the sides of the motor vehicle 11,21 or at the front.

[0038] The screen 4 of the optical unit 2 of the first motor vehicle 11 is intended to display a first part M1 of a pattern M ([Fig. 1]). It is understood that a pattern M can, for example, correspond to an image, a message, or a video. Thus, the pattern M can correspond, for example, and without limitation, to a photograph, a written message, or a film. It is understood that the first part M1 of the pattern M therefore corresponds to a portion of the image, message, or video to be projected. The screen 4 of the optical unit 2 of the second motor vehicle 21 is intended to display a second part M2 of the pattern M ([Fig. 2]). It is therefore understood that the second part M2 of the pattern M is different from the first part M1 and corresponds here to another portion of the image, message, or video to be projected.

[0039] The first and second motor vehicles 11, 21 further each include means 5 for communication with another motor vehicle. Here, the first motor vehicle 11 is intended to display a first part M1 of the pattern, and the second motor vehicle is intended to display a second part M2 of the pattern M. The communication means 5 are intended to receive at least one piece of information F from the other motor vehicle 11, 21 and / or from a communication infrastructure 7. This communication can be direct, vehicle-to-vehicle, or indirect, for example via the communication infrastructure 7, such as a server or a communication network.These five means of communication are known in themselves and include any means conventionally enabling long-distance communication between two motor vehicles (sometimes called V2V communication), for example, by radio communications such as Dedicated Short Range Communications (DSRC) or by communication based on the mobile telephone network. These five means of communication also include any means conventionally enabling long-distance communication between a motor vehicle and a communication infrastructure (for example, V2X, V2D, V2I, or V2N communications), for example, communication based on Wi-Fi or the mobile telephone network.

[0040] Each motor vehicle 11, 21 further comprises control means (not shown) for modulating the display of the first part M1 and second part M2 of the pattern M by the optical unit 2, respectively, according to the information F received from the other motor vehicle 11, 21 or from the communication infrastructure 7. It is understood, for example, that this modulation may consist of a modification of the nature or size of the part M1, M2 of the pattern M to be displayed. The control means comprise, for example, a unit of electronic control (not shown) capable of receiving and processing information F received by means of communication 5 from another motor vehicle and / or from a communication infrastructure 7 and capable of commanding, for example, the optical unit 2, a modification of the part M1, M2 of pattern M to be displayed.

[0041] The control means of each motor vehicle 11, 21 include synchronization means for modulating a display respectively of the first part M1 and the second part M2 of the pattern M by the respective optical units 2 according to the information F received from the other motor vehicle 11, 21 or from the communication infrastructure 7 so as to synchronize the display of the first part M1 of the pattern M with the display of the second part M2 of the pattern M in order to display at least a portion of the pattern M. The synchronization means process in particular information relating to the respective positions of the motor vehicles and to the nature and size of the display of the pattern M.

[0042] Figure 2 illustrates a virtual plane 8 onto which the pattern M to be displayed by the motor vehicles 11, 21 is projected. In this case, the virtual plane 8 extends orthogonally to the road on which the motor vehicles 11, 21 are traveling. The pattern M projected onto this virtual plane 8 corresponds to the hypothetical pattern M that would be fully visible if a screen the size of the virtual plane were available. It is understood that the respective screens 4 of the first and second motor vehicles 11, 21 have, in this case, a display area smaller than that of the virtual plane 8. Thus, they are intended to display only a portion M1, M2 of the pattern M. It is understood that the virtual plane 8 is not necessarily planar in the geometric sense of the term. In particular, depending on the embodiment, it is understood that this virtual plane 8 may, for example, be curved or have any three-dimensional structure.

[0043] It is understood that the parts of pattern M1, M2 displayed by the first and second motor vehicles 11, 21 depend on the respective positions of these motor vehicles 11, 21 with respect to the virtual plane 8. It is understood in particular that the virtual plane 8 is fixed in space, at least for a given time, and that by moving with respect to the virtual plane 8, the first and second motor vehicles 11, 21 display the parts M1, M2 of pattern M which correspond to their positions with respect to the virtual plane 8.

[0044] According to one embodiment, the respective optical units 2 of the motor vehicles 11, 21 are capable of displaying a holographic image. For this purpose, the optical units include means for displaying a holographic image. These means are known per se and will not be detailed here.

[0045] According to one embodiment, the optical unit 2 is capable of displaying a first version of the first part Ml of pattern M from a first viewing angle and a The second version of the first part Ml of pattern M, different from the first version of the first part Ml of pattern M, is shown from a second viewpoint. It is understood that this allows for improved display of the part Ml of pattern M by taking into account the observers' positions, so that they see a part Ml of pattern M that is essentially the same regardless of their position relative to the vehicle.

[0046] According to a particular embodiment, at least one of the motor vehicles 11, 21 further comprises means for estimating the probability of a future movement of the motor vehicle 11 or the other motor vehicle 21, the control means being configured to modulate a display of the first part M1 or the second part M2 of the pattern M by the optical unit 2 according to an estimate of a probability of a future movement provided by the means for estimating a probability of a future movement. It is thus possible to anticipate a future movement, using, for example, artificial intelligence that determines the most probable next movement of the motor vehicle 11, 21 based, for example, on a user's driving habits and / or the environment of the motor vehicle.This anticipation allows for better display responsiveness by anticipating the portion of the pattern M1, M2 that will be displayed next. This results in a higher quality, more responsive, and smoother display. Furthermore, this anticipation helps to mitigate potential communication problems related, for example, to interrupted or slow communication, or a weak or poor-quality communication signal between the first and second motor vehicles 11, 21, or between the first motor vehicle 11 or the second motor vehicle 21 and the communication infrastructure 7.

[0047] We describe below, with reference to Figures 3 to 6, a method for displaying at least a portion of the motif M by two motor vehicles 11, 21 as described above. According to this embodiment, at least a portion of a motif M, here an advertising image represented by a star, is to be displayed on the screens 4 of the motor vehicles 11, 21. To do this, the following steps are carried out: a) A first of the motor vehicles 11 displays on its screen 4 a first part M1 of the pattern M, b) A second of the motor vehicles 21 displays on its screen 4 a second part M2 of the pattern M, c) The display of the screen 4 of the optical unit 2 of at least one of the first and second motor vehicles 11, 21 is modulated according to at least one piece of information F exchanged between the first and second motor vehicles 11, 21 and / or according to at least one piece of information F exchanged between the first or second motor vehicles 11, 21 and a communication infrastructure 7, this information F being relative to at least one of a geographical position of the first motor vehicle 11, a geographical position of the second motor vehicle 21, and a relative position of the first and second motor vehicles 11,21 with respect to each other so as to synchronize the display on the screens 4 of the first and second parts M1, M2 of the pattern M with respect to each other and thus display at least a portion of the pattern M.

[0048] The means for synchronizing the control means make it possible in particular to ensure that the first and second parts M1, M2 of the pattern M are properly synchronized in space and time in order to correctly display at least a portion of the pattern M.

[0049] Advantageously, the modulation of the display of the optical unit 2 as a function of the information F exchanged between the first and second motor vehicles 11, 21 and / or as a function of the information F exchanged between the first or second motor vehicles 11, 21 and a communication infrastructure 7 is carried out continuously over time as long as the display of the pattern M is desired. Thus, it is possible to modify the portions M1, M2 of pattern M displayed by the first and second motor vehicles 11, 21 in real time, dynamically, thereby improving the perception of the portion of pattern M that is displayed and giving an impression of fluidity in the display.

[0050] According to one embodiment, the information F exchanged between the first and second vehicles 11, 21 relates to the respective positions in space of the first vehicle 11 and the second vehicle 21. It is understood that this information F can relate to the exact geographical position, determined, for example, using GPS technology, or to the relative position between the first and second vehicles 11, 21, determined, for example, using sensors such as cameras or radar. For example, it is possible to command the movement of one of the vehicles 11, 21 to ensure proper positioning of both vehicles and thus ensure that the portion of the pattern M is displayed with parts M1, M2 synchronized in time and space, allowing for a high-quality visual rendering.

[0051] According to one embodiment, the information F exchanged between the first and second motor vehicles 11,21 relates to the first and second parts M1, M2 of the pattern M that the first and second motor vehicles 11,21 are intended to display.

[0052] According to one embodiment, modulating the display of the optical unit 2 of at least one of the first and second motor vehicles 11, 21 consists of controlling a modification of the part of the pattern M that is displayed by the screens 4 of the respective optical units 2 of the first and / or second motor vehicles 11, 21. It It is thus possible to correct in real time, dynamically, any display imperfections and to synchronize the displays of parts M1, M2 of pattern M with each other.

[0053] According to one embodiment, the modulation of the display of the optical unit 2 of at least one of the first and second motor vehicles 11, 21 consists of controlling a movement of at least one of the first and second motor vehicles 11, 21. It is understood that this control of a movement of the vehicle can be direct, without the need for intervention by a driver, with a so-called autonomous movement of the vehicle, or indirect, by giving movement instructions to a user of the vehicle, for example by means of displaying instructions on the dashboard.

[0054] The method can be implemented whether the first and second motor vehicles 11, 21 are moving or stationary. When they are moving, it is particularly advantageous for the communication systems of the two motor vehicles 11, 21 to exchange information relating to the positioning of the two motor vehicles 11, 21 relative to each other. It is then possible, in particular, to take into account differences in perspective if the two motor vehicles 11, 21 are not at the same level on the road so that a person located behind the two motor vehicles 11, 21 observes a pattern M whose proportions of the different parts M1, M2 mitigate the difference in perspective.Typically, if the first motor vehicle 11 is farther from the observer than the second motor vehicle 21, it is advantageous to increase the displayed proportions of the first part M1 of pattern M relative to those of the second part M2 of pattern M, and vice versa. Furthermore, if one of the motor vehicles 11, 21 moves closer to the other, a modification of the displayed part M1, M2 of the pattern is planned to account for the reduction in space E between the motor vehicles 11, 21.

[0055] As illustrated in figures 2 and 3, the pattern M to be displayed is projected into the virtual plane 8, the first part M1 of pattern M and the second part M2 of pattern M being determined according to the respective positions of the first and second motor vehicles 11,21 with respect to the virtual plane 8.

[0056] Thanks to the method according to the invention, an observer has the impression that the first and second motor vehicles 11, 21 are moving in a virtual plane 8 in which the pattern M is projected. Thus, the respective screens 4 of the first and second motor vehicles 11, 21 display the part M1, M2 of the pattern M that corresponds to their respective positions in this virtual plane 8. Figure 3 illustrates the position of the first and second motor vehicles 11, 21 in the virtual plane 8 for an observer located behind the motor vehicles 11, 21. The part of the pattern M that The area represented by the dashed line corresponds to its projection onto the virtual plane 8; it is therefore not visible to an observer. The parts M1 and M2 of pattern M, represented by solid lines, correspond to those displayed by the respective screens 4 of the first and second motor vehicles 11 and 21. These parts M1 and M2 thus correspond to the parts of pattern M that are visible to an observer. Figure 4 illustrates more specifically what an observer located behind the first and second motor vehicles 11 and 21 sees; the virtual plane 8 is therefore not shown.

[0057] As previously stated, the first and second motor vehicles 11, 21 display the portion M1, M2 of the pattern M that corresponds to their positioning in space relative to the virtual plane 8. Thus, as illustrated in [Fig. 5], when the first and second motor vehicles 11, 21 move relative to the virtual plane 8, the portions M1, M2 of the pattern M that they display change. In [Fig. 5], it can be seen that the first and second motor vehicles 11, 21 have moved to the left relative to their positioning illustrated in [Fig. 3]. The portions M1, M2 of the displayed pattern M have been modified accordingly. These portions M1, M2 therefore correspond to the portions of the pattern M that are visible to an observer. [Fig. 6] illustrates more specifically what an observer located behind the first and second motor vehicles 11, 21 sees; the virtual plane 8 is therefore not shown.

[0058] It is understood that when the first and second motor vehicles 11, 21 move from their respective positions illustrated in Figures 3 and 4 to their respective positions illustrated in Figures 5 and 6, the displayed parts M1, M2 of pattern M change dynamically, in real time, in order to correspond to the positionings of the first and second motor vehicles 11, 21 with respect to the virtual plane 8. An observer therefore has the impression that the motor vehicles 11, 21 are moving in the pattern M.

[0059] The instruction on the pattern to be displayed can have different origins depending on the embodiment. For example, it can be provided that the instruction comes from the communication infrastructure 7 or from one of the motor vehicles 11, 21. In particular, it can be provided that an occupant of one of the motor vehicles can use an electronic device, such as a smartphone or a tablet, comprising means of communication with the communication means 5 of the motor vehicle 11, 21 that he occupies, in order to send instructions on the pattern M to be displayed by the motor vehicle(s) 11, 21.

[0060] According to one embodiment, when at least one of the first and second motor vehicles 11, 21 leaves the field of the virtual plane 8, the display of the optical unit 2 of this at least one of the first and second motor vehicles 11, 21 is modulated so as to display a part M1, M2 of a pattern created by generation means of pattern parts based on pattern M. Pattern part generation methods include, for example, methods using artificial intelligence to generate new pattern parts based on pattern M. These new pattern parts are therefore preferably stylistically consistent with the original pattern M. This prevents a situation where, when one of the motor vehicles 11, 21 leaves the field of the virtual plane 8, it ceases to display a part M1, M2 of pattern M, thus reducing the number of motor vehicles 11, 21 displaying pattern M.

[0061] According to one embodiment, when the planned display time of the pattern M, referred to as the original pattern, is exceeded, the display of the optical unit 2 of at least one of the motor vehicles 11, 21 is modulated so as to display parts M1, M2 of a new pattern created by means for generating a new pattern based on the original pattern M. As with the means for generating parts of a pattern, the means for generating a new pattern typically include artificial intelligence for generating new patterns based on the original pattern M. Thus, the duration for which a pattern is displayed is extended, with continuity of style, even when the planned display time for the original pattern M is exceeded.

[0062] According to one embodiment, when a latency greater than a predetermined threshold is detected for the exchange of information F between the first and second motor vehicles 11, 21 and / or between the first or second motor vehicles 11, 21 and the communication infrastructure 7, the display of the optical unit of at least one of the first and second motor vehicles 11, 21 is modulated so as to display parts M1, M2 of pattern M created by means of generating part M1, M2 of pattern M on the basis of at least one piece of information F previously exchanged between the first and second motor vehicles 11, 21 and / or between the first or second motor vehicles 11, 21 and the communication infrastructure (7) and on the basis of the parts M1, M2 of pattern M previously displayed by the optical units 2 of the first and second motor vehicles 11, 21.The means for generating parts M1, M2, of pattern M include, for example, artificial intelligence designed to generate pattern parts based on the information F exchanged and the parts M1, M2 of pattern M previously displayed. Thus, in the event of latency exceeding the predetermined threshold, there are no cuts or interruptions in the display of parts M1, M2 of pattern M2 by the optical units 2 of the first and second motor vehicles 11, 21, thereby improving the quality and fluidity of display even in the event of latency in communication between the motor vehicles 11, 21 and / or between the motor vehicles 11, 21 and the communication infrastructure 7.

[0063] The invention is not limited to the embodiments presented in the detailed description, and other embodiments will be obvious to a person of the In particular, a process involving two motor vehicles has been described. However, depending on the embodiments, it can be foreseen that a larger number of motor vehicles may be involved in displaying at least a portion of the pattern M, for example between three and ten, or even more.
