Description

Title of the invention: Motor vehicle intended to display or project part of a pattern and method for projecting and / or displaying a pattern Technical field of the invention

[0001] The invention relates to a motor vehicle. The invention also relates to a method for projecting and / or displaying a pattern. Technical background

[0002] The technology of motor vehicles whose headlights are capable of projecting a pattern, such as an image or video, onto a surface, for example in order to project a film, is already known. Document EP3217377A1 describes, for example, a motor vehicle capable of projecting a pattern onto the road.

[0003] Prior art is also 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.

[0004] The patterns projected or displayed by prior art vehicles are limited, particularly in terms of size, by the projection or display capabilities of the motor vehicle. Such a limitation may not be compatible with the nature of the pattern to be projected or displayed. Furthermore, such a limitation reduces the visibility of the pattern and the viewing comfort for those watching it.

[0005] Thus, it is particularly desirable to overcome this limitation to the projection and / or display capabilities of a motor vehicle. Summary of the invention

[0006] The invention is intended in particular to overcome the aforementioned disadvantages.

[0007] To this end, the invention relates to a motor vehicle, characterized in that it understand : - an optical unit intended to display or project a first part of a pattern, - means of communication with another motor vehicle, the other vehicle being intended to display or project a second part of the pattern, the means of communication being intended to receive at least one piece of information from the other motor vehicle, - control means intended to modulate the display or projection of the first part of the pattern by the optical unit according to the information received from the other motor vehicle

[0008] Thus, by dividing the pattern to be projected or displayed between several motor vehicles, each motor vehicle being capable of displaying a part of this pattern, it is possible to overcome the limitations of the optical unit of a given motor vehicle, in particular with regard to the size of the pattern to be displayed.

[0009] Furthermore, the communication means allow the motor vehicles to communicate relevant information to each other in order to modulate the pattern parts to be displayed by each of the motor vehicles. Without limitation, this information relates, for example, to the nature of the pattern part to be displayed, the dimensions of the pattern part to be displayed, the color range of the pattern part to be displayed, or the position in space of the motor vehicles (absolute position or relative position with respect to the other motor vehicle).

[0010] The control means use this information to modulate the display or projection of the portion of the pattern. For example, this modulation may consist of modifying the nature or size of the portion of the pattern to be displayed, or of shifting the portion of the pattern projected or displayed by the optical unit in space. It is thus possible to ensure synchronized projection or display in time and space of the different parts of the pattern in order to obtain a reconstructed pattern with 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 different motor vehicles.The control means include, for example, an electronic control unit capable of receiving and processing information received through communication with another motor vehicle and capable of commanding, for example, the optical unit to modify the part of the pattern to be projected or 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 or projection of the first part of the pattern by the optical unit according to the information received from the other motor vehicle so as to synchronize the display or projection of the first part of the pattern with a display or projection of the second part of the pattern in order to display or project the pattern.

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

[0014] - the optical unit includes at least one projector of the motor vehicle.

[0015] The invention also relates to a method for projecting and / or displaying a pattern by at least two motor vehicles as described above, in which: a) The first of the motor vehicles projects and / or displays a first part of the pattern, b) a second of the motor vehicles projects and / or displays a second part of the pattern, (c) The projection and / or 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 in such a way as to synchronize the projection or display of the first and second parts of the pattern with each other and thus project or display the pattern

[0016] It is thus possible to ensure the projection or display of a large-scale pattern in a synchronized manner in time and space by at least two different vehicles. The reconstructed pattern obtained from the pattern parts can therefore easily have significant dimensions with sufficient quality for a person viewing the pattern to spontaneously understand that the different projected or displayed parts form a single pattern and to have an impression of continuity between the different parts of the pattern.

[0017] As indicated previously, in a non-restrictive manner, the information exchanged between the first and second motor vehicles relates, for example, to the nature of the part of the pattern to be displayed, the dimensions of the part of the pattern to be displayed, the color range of the part of the pattern to be displayed, or the position in space of the motor vehicles (absolute position or relative position with respect to the other motor vehicle).

[0018] The invention may include one or more of the following optional features, taken alone or in combination:

[0019] - The information exchanged between the first and second vehicles relates to the position in space of the first motor vehicle or the second motor vehicle.

[0020] - The information exchanged between the first and second motor vehicles relates to the first and second parts of the design that the first and second motor vehicles are intended to project or display.

[0021] - The modulation of the projection and / or display of the optical unit of at least one of the first and second motor vehicles consists of controlling the optical unit of at least one of the first and second motor vehicles in such a way as to move the projections and / or displays of the first and second parts of the pattern relative to each other.

[0022] - The modulation of the projection and / or 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 or projected by the respective optical units of the first and / or second motor vehicles.

[0023] - The modulation of the projection and / or 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. Brief description of the figures

[0024] The invention will be better understood upon reading the following description, given solely by way of example and made with reference to the accompanying drawings in which:

[0025] [Fig-1] is a schematic perspective representation of a front part of a motor vehicle according to an embodiment of the invention;

[0026] [Fig.2] is a schematic top view representation of two motor vehicles according to the invention intended to implement the method of projecting a pattern according to an embodiment of the method of projecting a pattern according to the invention;

[0027] [Fig.3] is a schematic rear view representation of two motor vehicles according to the invention intended to implement the method of displaying a pattern according to an embodiment of the method of displaying a pattern according to the invention. Detailed description

[0028] Figure [Fig.1] shows a motor vehicle 1 according to one embodiment of the invention.

[0029] The motor vehicle 1 comprises an optical unit 2 including, in this case, two projectors 3 located on the front face of the motor vehicle 1 ([Fig. 1]). In another embodiment, the optical unit 2 may also comprise a single projector 3.

[0030] The projectors 3 of the optical unit 2 are intended to project a first part M1 of a pattern M ([Fig. 2]). It is understood that a pattern M can correspond to an image, a message, or a video. Thus, the pattern M can correspond, for example, but not limited to, 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.

[0031] Furthermore, according to another embodiment, the optical unit 2 comprises a screen 4 for displaying a first part M1 of a pattern M ([Fig. 3]). More particularly, in the present case, the screen 4 is located on the rear face of the motor vehicle 1, specifically on a rear window. According to other In embodiments, the screen(s) 4 may be located elsewhere on the motor vehicle 1, for example on the sides of the motor vehicle 1 or on the front face.

[0032] The motor vehicle 1 further includes means 5 for communicating with another motor vehicle, the other vehicle being intended to display or project 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. This communication may be direct, vehicle-to-vehicle, or indirect, for example via a server or a network. These communication means 5 are known per se 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.

[0033] The motor vehicle 1 further comprises control means (not shown) for modulating a display or projection of the first part M1 of the pattern M by the optical unit 2 according to the information F received from the other motor vehicle. The control means use the information F to modulate the display or projection of the first part M1 of the pattern M. It is understood, for example, that this modulation may consist of a modification of the nature or size of the part of the pattern to be displayed, or even a displacement in space of the part of the pattern projected or displayed by the optical unit 2.The control means include, for example, an electronic control unit (not shown) capable of receiving and processing information F received by means 5 of communication with another motor vehicle and capable of commanding, for example, the optical unit 2, a modification of part M1 of pattern M to be projected or displayed.

[0034] The control means include synchronization means for modulating a display or projection of the first part M1 of the pattern M by the optical unit 2 according to the information F received from the other motor vehicle so as to synchronize the display or projection of the first part M1 of the pattern M with a display or projection of the second part M2 of the pattern M in order to display or project the pattern M. The synchronization means process, for example, information relating to the respective positions of the motor vehicles and to the nature and size of the display or projection of the pattern M in order to match, by overlapping or by juxtaposition side by side, the parts M1, M2 of the pattern M and thus generate a pattern M of good visual quality, faithful to the pattern M whose display or projection is desired.

[0035] We describe below, with reference to [Fig. 2], a method for projecting the motif M by two motor vehicles 1 as described above. According to this embodiment, a motif M, here a film, is to be projected onto a projection surface 6, for example a white screen or a wall.To do this, the following steps are carried out: a) a first 11 of the motor vehicles 1 projects, using its projectors 3, a first part M1 of the pattern M onto the projection support 6, b) a second 21 of the motor vehicles 1 projects, using its projectors 3, a second part M2 of the pattern M onto the projection support 6, c) the projection 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 so as to synchronize the projection of the first and second parts M1, M2 of the pattern M with respect to each other, in space and time, and thus project the pattern M onto the projection support 6.

[0036] It is noted that a portion M3 of the pattern M corresponds to a portion of the pattern M where the projections of the first and second parts M1, M2 of the pattern are superimposed. The synchronization means of 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 display a correct pattern M.

[0037] According to one embodiment, the information F exchanged between the first and second vehicles 11, 21 relates to the spatial position of the first and second vehicles 21. It is understood that this information F may refer 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 to ensure proper positioning of both vehicles and thus ensure the projection of a high-quality pattern M.

[0038] 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 project. For example, when verifying the nature of the parts M1, M2 to be projected, it is useful to be able to ensure that the combination, juxtaposition, or superposition of the first and second parts M1, M2 allows the pattern M to be reproduced in its entirety, without any missing or duplicated parts.

[0039] According to one embodiment, the modulation of the projection of the optical unit 2 of at least one of the first and second motor vehicles 11, 21 consists of controlling the optical unit 2 of at least one of the first and second motor vehicles 11, 21 so as to move the projections of the first and second parts M1, M2 of the pattern M relative to each other.

[0040] According to one embodiment, the modulation of the projection 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 which is projected by the projectors 3 of the respective optical units 2 of the first and / or second motor vehicles 11, 21. It is thus possible to correct in real time, in a dynamic manner, any possible projection imperfections.

[0041] According to one embodiment, modulating the projection of the optical unit 2 of at least one of the first and second motor vehicles 11, 21 consists of controlling the movement of at least one of the first and second motor vehicles. It is understood that this control of vehicle movement can be direct, without the need for driver intervention, resulting in so-called autonomous vehicle movement, or indirect, by giving movement instructions to a vehicle user, for example, by means of displaying instructions on the dashboard.

[0042] We describe below, with reference to [Fig. 3], a method for displaying the motif M by two motor vehicles 1 as described above. According to this embodiment, a motif M, here an advertising message, is to be displayed on the screens 4 of the motor vehicles. To do this, the following steps are carried out:

[0043] 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 so as to synchronize the display on the screen 4 of the first and second parts M1, M2 of the pattern M with respect to each other and thus display the pattern M.

[0044] The method can be implemented when 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 make it possible to mitigate the difference in Perspective. Typically, if the first vehicle 11 is farther from the observer than the second vehicle 21, it is advantageous to reduce the proportions of the first part M1 of pattern M relative to the second part M2 of pattern M, and vice versa. Furthermore, if one of the vehicles 11, 21 moves closer to the other, it is useful in certain cases (for example, when the pattern is an image) to modify the displayed part M1, M2 of the pattern to account for the reduction in space E between the vehicles 11, 21.

[0045] According to one embodiment, the information F exchanged between the first and second vehicles 11, 21 relates to the position in space of the first motor vehicle 11 and the second motor vehicle 21. It is understood that this information F may relate to the exact geographical position, determined, for example, using GPS technology, or to the relative position between the first and second motor vehicles 11, 21, determined, for example, using sensors such as cameras or radar. It is possible, for example, to command the movement of one of the motor vehicles to ensure proper positioning of the two motor vehicles 11, 21 and thus ensure the display of a high-quality pattern M.

[0046] 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. For example, when verifying the nature of the parts M1, M2 to be displayed, it is useful to be able to ensure that the combination of the first and second parts M1, M2 allows the pattern M to be reproduced in its entirety, without any missing or duplicate parts.

[0047] According to one embodiment, the modulation of the display of the screen 4 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 which is displayed by the screens 4 of the respective optical units 2 of the first and / or second motor vehicles 11, 21. It is thus possible to correct in real time, in a dynamic manner, any imperfections or inconsistencies in the display.

[0048] According to one embodiment, the modulation of the display of the screen 4 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.
