Brief description of figures

Other characteristics and advantages of the invention will emerge from the description of the non-limiting embodiments of the invention below, with reference to the appended figures 1 to 3, in which:

schematically illustrates a part of the passenger compartment of a vehicle, according to a particular embodiment of the present invention;

schematically illustrates a device of a system configured to display one or more images on a vehicle display screen of the , according to a particular embodiment of the present invention;

illustrates a flowchart of the different steps of an image display process for the vehicle of the , according to a particular embodiment of the present invention.

A method and a device for displaying image(s) for a vehicle will now be described in what will follow with reference in conjunction with FIGS. 1 to 3. The same elements are identified with the same reference signs throughout the description that follows.

According to a particular and non-limiting embodiment of the invention, a mobile communication device (for example a smart telephone (“Smartphone”)) receives first image data from the external environment of a vehicle, this first data being received via a wireless link from one or more cameras mounted on the vehicle. The mobile communication device transmits, by a wireless link or by a wired link, a set of second data representative of one or more images of the exterior environment of the vehicle to a computer of the on-board system of the vehicle, for example the computer IV. The second data correspond for example to the first data or to a version after processing of the first data. The image or images corresponding to the second data received are displayed on a display screen of the vehicle, such a display being controlled by the computer IVI for example.

Such a display method makes it possible to use an existing screen of the vehicle to display images of the environment outside the vehicle acquired by one or more cameras connected in wireless communication with a mobile communication device. Such a method thus makes it possible to benefit from an existing display screen of the vehicle without modifying the architecture of the on-board system of the vehicle, the image data being received, and potentially processed, by the mobile communication device before being sent to the vehicle , for example according to a so-called screen mirroring mode. This makes it possible in particular to reduce the costs of installing the system for monitoring the external environment while improving the safety of the vehicle by offering the possibility to the driver of the vehicle of having a visual view of the external environment when he or she performs maneuvers.

schematically illustrates part of a passenger compartment of a vehicle 10, according to a particular and non-limiting embodiment of the present invention.

There presents a view of the interior of a vehicle 10, in particular of the front part of the passenger compartment of the vehicle 10 comprising in particular the steering wheel and the dashboard or the dashboard of the vehicle 10.

The vehicle 10 corresponds for example to a vehicle with a combustion engine, with electric motor(s) or else a hybrid vehicle with a combustion engine and one or more electric motors. The vehicle 1 thus corresponds for example to a land vehicle, for example an automobile, a truck, a coach.

According to the example of , a display screen 100 is integrated into the dashboard of the vehicle 10. The display screen 100 corresponds for example to an LCD type screen (from the English "Liquid Crystal Display" or in French "Display to liquid crystals"), for example of the TFT type (from the English "Thin-Film Transistor" or in French "Thin film transistor"), or OLED (from the English "Organic Light-Emitting Diode" or in French "Organic light-emitting diode"). The display screen 100 is for example arranged in the center of the dashboard, for example above a central facade. Of course, the position of the display screen 100 is not limited to this example, the display screen 100 being able to be arranged in any position, for example on the central facade.

According to another example, the display screen 100 corresponds to a transparent screen, suitable for displaying images or graphic content while offering the possibility of seeing through it. Such a screen is for example arranged on the dashboard in front of the windshield, in the head-up position. Such a transparent screen corresponds for example to an LCD panel and of the TFT type (from the English “Thin-Film Transistor” or in French “Thin Film Transistor”).

According to a variant embodiment, the display screen 100 is a touch screen allowing a user to interact with the graphic contents displayed on this screen 100 in a tactile way, for example by clicking via a tactile press on icons to open new pages of the graphical interface displayed, to navigate in menus by swiping the screen from top to bottom, to enlarge or reduce a window by moving two fingers apart or bringing them together, etc.

A mobile communication device 101 is advantageously connected to the display device 100 via a wireless connection or link. The mobile communication device 101 advantageously comprises a display screen configured to display graphical content generated by one or more man-machine interfaces, in particular a graphical interface. The graphical interface displayed on the screen of the device 101 corresponds for example to a graphical interface of an operating system installed on the device 101 (for example Android® or iOS from the company Apple®) or to a graphical interface of a mobile application installed or executed on the device 101. Such a mobile application is for example configured to receive first image data acquired by one or more cameras 102 connected in communication with the mobile communication device 101, for example via a Bluetooth® or Wifi® type wireless link, for example Wifi Direct (according to IEEE 802.11, for example according to IEEE 802.11n or IEEE 802.11ac).

The mobile communication device 101 corresponds for example to a smart phone, a tablet, a connected object configured to transmit and receive data via a wireless connection. The wireless connection is based for example on Bluetooth® or Wifi® technology, for example Wifi Direct (according to IEEE 802.11, for example according to IEEE 802.11n or IEEE 802.11ac).

According to a variant, the mobile communication device 101 is configured to transmit and receive data via a wired connection, for example using a USB cable (from the English “Universal Serial Bus” or “Universal Serial Bus” in French) .

The mobile communication device 101 is advantageously configured to communicate data with the display screen 100 via one or more computers of the vehicle's on-board system 10. For example, the data transmitted by the device 101 intended for the screen 100 are received by a telematics control unit, called TCU (from the English “Telematic Control Unit”), connected in communication with the central computer of the on-board system via a data bus. The TCU is connected to one or more antennas of the vehicle for data communication between the vehicle and one or more remote devices, for example the mobile communication device 101. The central computer is advantageously connected to the computer IVI via a data bus, the IVI computer controlling the infotainment system of the vehicle 10 and the data to be displayed on the display screen 100. These computers, that is to say the TCU, the central computer and the IVI computer advantageously form an architecture multiplexed for the performance of various useful services for the correct operation of the vehicle 10. The computers communicate and exchange data between them via one or more computer buses, for example a communication bus of the CAN data bus type ( from English “Controller Area Network” or in French “Réseau de Contrôleurs”), CAN FD (from English “Controller Area Network Flexible Data-Rate” or e n French “Flexible Data Rate Controller Network”), FlexRay (according to ISO 17458 standard) or Ethernet (according to ISO/IEC 802-3 standard).

A software module implementing an interactive application (also called interactive thumbnail or widget) configured to establish wireless communication with the mobile communication device 101 is for example installed on the IVI computer, allowing the IVI computer to manage the data streams received from the mobile communication device 101 for display of one or more images on the screen 100. This software module is also configured to transmit to the mobile communication device 101 requests or commands received for example from the screen 100. such requests correspond for example to commands entered by a user using the touch screen 100 as a communication interface with the mobile communication device 101. This software module is for example dependent on the operating system installed on the mobile communication device 101 which also embeds a software module configured to communicate with the module e software executed by the IVI computer.

According to a variant embodiment, the TCU, the central computer and the IVI computer form a single hardware device, for example a computer, each of the functions provided by the TCU, the central computer and the IVI computer being implemented in software manner in this single device according to this variant.

The display screen 100 (for example via the IVI computer controlling the display screen 100) and the mobile communication device 101 are for example configured to implement a so-called screen mirroring technology. » in English) according to which the graphic content displayed on the screen of the mobile communication device 101 is also displayed on the display screen 100. The data corresponding to the content(s) displayed on the screen of the mobile communication device 101 are transmitted to the display screen 100 by the mobile communication device 101 via the wireless or wired connection established between the mobile communication device 101 and the vehicle 10 (i.e. say the vehicle's on-board system 10, including the IVI computer controlling the display screen 100).

According to this technology, the video stream comprising the data to be displayed on the screen of the mobile communication device 101 is transmitted by the mobile communication device 101 to the display screen 100 for display on this display screen 100 The data corresponding to a content displayed on the screen of the mobile communication device 101 correspond to image data or graphic interface(s) data.

The vehicle 10 advantageously embeds a camera 102. The camera 102 corresponds for example to a camera added to the vehicle 10 in addition to the standard equipment. According to a variant, the camera 102 corresponds to a camera fitted to the vehicle 10 originally.

The camera 102 is advantageously installed so as to have in its field of vision part of the external environment around the vehicle 10. The camera 102 corresponds for example to a camera having in its field of vision the rear of the vehicle 10. This camera 102 is for example electrically connected to vehicle 10. According to a variant, camera 102 comprises a rechargeable battery supplying electricity to the electronics in charge of image data acquisition.

According to a variant, the vehicle 10 is equipped with several cameras 102, for example, 2 or 4 cameras (for example a camera having in its field of vision the rear exterior environment of the vehicle 10 and a camera having in its field of vision the exterior environment before the vehicle 10 and/or the side cameras of the vehicle 10 having in their field of vision the left/right exterior environment of the vehicle 10).

A system comprising the mobile communication device 101 connected in communication with one or more computers of the vehicle's on-board system 10 is configured for the implementation of a process for displaying one or more images on the display screen 100 of the vehicle 10, the process comprising the operations described below according to a particular embodiment of the invention.

In a first operation, the camera 102 acquires initial data representative of the environment outside the vehicle in its field of vision. These first data correspond for example to the acquisition data of a grid of photosensitive sensors, for example gray level data for each RGB color channel for example (from the English “Red, Green, Blue” or in French “ Red, green, blue”).

These first data are advantageously transmitted to the mobile communication device 101 via a wireless connection of the Wifi® or Wifi Direct type for example.

The acquisition of the first image data is for example triggered by the reception of a request transmitted by the mobile communication device 101 intended for the camera 102 via the wireless connection. The exchange of data between the camera 102 and the mobile communication device 101 is for example implemented via a mobile application installed and executed on the mobile communication device 101.

In a second optional operation, the mobile communication device 101 performs processing on the first image data received from the camera(s) 102 to obtain a set of second image data or a sequence of images.

For example, when the mobile communication device 101 receives several streams of first data emitted by several cameras 102, the mobile communication device 101 merges the first data to obtain in a single image a representation of the external environment covered by the set cameras 102.

According to another example, the mobile communication device 101 implements one or more of the following image processing methods:

- image compression method, for example conforming to the H.264 or H.265 standard;

- application of one or more filters, for example to reduce noise;

- object detection and/or recognition.

A set of second data representative of each image of a sequence of images are obtained at the output of this second operation after processing of the first image data by the mobile communication device 101.

When no processing is applied to the first data, the second data transmitted by the mobile communication device 101 corresponds to the first data.

The second data correspond for example to the data associated with each pixel of an image, an image corresponding to a table of pixels (for example according to M rows and N columns, M and N being whole numbers depending on the definition of the image ).

In a third operation, the mobile communication device transmits a stream of second data representing an image or a sequence of images of the exterior environment of the vehicle 10 to the IVI computer of the vehicle 10.

The transmission is for example made according to a wireless connection (for example of the Wifi® or Wifi-Direct type) or according to a wired connection (for example via USB or HDMI (from the English "High-Definition Multimedia Interface" or in French “High Definition Multimedia Interface”)).

The transmission is for example triggered by the mobile communication device 101 following receipt of a request sent by the IVI computer to the mobile communication device 101. According to this example, the driver or a passenger of the vehicle 10 starts an interactive application (that is to say a widget), for example by clicking on an icon of the interactive application included in the man-machine interface of the infotainment system of the vehicle 10 displayed on the screen of display 100. Upon receipt of the touch command commanding the start of the interactive application, the computer IVI launches the execution of the interactive application, the execution triggering the transmission of the request intended for the mobile communication device 101 to receive the second data.

According to this example, the mobile application in charge of receiving the first data from the camera(s) 102 transmits a request to the camera(s) 102 to receive the first data of the images of the exterior environment of the vehicle 10 upon receipt of the request. received from the IVI computer requiring the transmission of the second data.

According to another example, the transmission of the second data by the mobile communication device 101 to the IVI computer is triggered by a user command carried out via the man-machine interface implemented by the mobile communication device 101. According to this other example, the user starts the mobile application in charge of receiving the first data from the cameras 102 and of displaying the images corresponding to these first data (or to the second data resulting from a video processing of the first data). The start of the mobile application is for example triggered by a tactile press on an icon associated with the mobile application and displayed on the screen of the mobile communication device 101. The images of the exterior environment of the vehicle 10 are displayed on the screen of the mobile communication device 101 via the ad hoc mobile application installed and executed on the device 101. When the screen duplication mode (or “screen mirroring” in English) is activated on the mobile communication device 101 automatically transmits the second data to the IVI computer which triggers the display of the image(s) corresponding to the second data received on the display screen 100 of the vehicle 10.

The communication between the IVI calculator and the mobile communication device (communication of request(s) and/or communication of the second data) is thus advantageously implemented between an interactive application implemented by the IVI calculator on the one hand and by a mobile application implemented by the mobile communication device 101 on the other hand. Data communication takes place, for example, according to the principle of so-called screen mirroring technology.

The display of the images of the exterior environment of the vehicle 10 is done for example only on the display screen 100. According to another example, the display of these images is implemented on the display screen 100 and on the screen of mobile communication device 101, as provided by screen mirroring technology.

Such a process allows the driver of vehicle 10 to view the exterior environment of vehicle 10 when desired, directly on the display screen 100 of vehicle 10. This enhances the safety of vehicle 10 and its passengers, as well as than that of any users located in the environment around the vehicle 10.

The display of images of the external environment on the display screen 100 offers comfort to the driver, such a screen 100 being generally larger than the screen of the mobile communication device 101, in particular when the latter corresponds to a smartphone.

Moreover, the system necessary for the implementation of the process is inexpensive for the owner of the vehicle because it comprises already existing elements/devices (computer(s) of the vehicle 10, mobile communication device 101), these existing devices requiring possibly only a software update for the installation of the interactive application and/or the mobile application, if this or these devices are not up to date. Only the camera(s) 102 are to be added if they are not originally provided in the vehicle 10.

Such a process also has the advantage of using the resources of the mobile communication device in terms of calculation and video processing (CPU resources (from the English "Central Processing Unit" or in French "central processing unit" and /or GPU (from the English "Graphics Processing Unit" or in French "graphic processor"), which makes it possible to reduce the load on the IVI computer.

The process described above, or at least a part of this process is advantageously implemented by the computer IVI and the mobile communication device 101 connected in communication to the computer IVI. According to a variant, the process, or at least part of this process, is implemented by a system comprising the computer IVI, the screen 100 and the mobile communication device 101 connected in communication to the computer IVI. According to yet another variant, the screen 100 comprises a processing unit similar to the IVI calculator and the process, or at least part of this process, is implemented by this screen 100 and the mobile communication device 101 connected in communication on the screen 100. According to an additional variant, the process described above is implemented by a system comprising the IVI computer, the screen 100 (or a device combining the IVI computer and the screen 100), the mobile communication device 101 and one or more cameras 102.
