Description of the examples of realization

A method and a device for controlling an on-board infotainment system in a vehicle will now be described in the following with reference in conjunction with FIGS. 1 to 6. The same elements are identified with the same reference signs throughout. of the following description.

According to a particular and non-limiting embodiment of the present invention, the control of an infotainment system, called IVI system, on board a vehicle comprises the reception, for example by a processor of the device in charge of controlling the IVI system , a first item of information representative of a first touch press on a first zone of a touch screen associated with the IVI system. The touch screen corresponds for example to the screen of a mobile communication device (for example a smart phone (“Smartphone”) or a tablet) or to a screen integrated into the dashboard of the vehicle. This first zone corresponds for example to a virtual touch button displayed on the screen. In response to receiving the first information, a first determined function of the IVI system is implemented, for example a multimedia content rendering function or a road navigation function. Receiving second information representing a second touch on the first area of the screen triggers the modification of one or more parameters associated with the first function activated during the first touch. Such a parameter depends on the function of the system implemented and corresponds for example to a change of source of the rendered multimedia content if the function corresponds to a function of rendering a multimedia content or to a change of mobile navigation application if the function corresponds to a road navigation function.

Such a method makes it possible to simplify the control of the IVI system by proposing to execute several actions from the same zone of the screen associated with a determined function of the IVI system, a first tactile press on this zone triggering the associated function and a second press to control the activated function.

Thus, the number of virtual buttons (or graphics) or control zones defined on a touch screen associated with the IVI system is reduced, which simplifies controls and improves the user experience.

There 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 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 10 thus corresponds for example to a land vehicle, for example an automobile, a truck, a bus, a motorcycle.

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 can be arranged in any position, for example on the central facade or can cover the dashboard on its entire length.

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.

According to a particular embodiment, a mobile communication device 101 is connected to the display device 100 via a wireless connection or link. The mobile communication device is connected for example directly to the display device 100 or via one or more computers of the vehicle's on-board system 10. The mobile communication device 101 advantageously comprises a display screen, advantageously tactile , 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 running on the device 101.

The mobile communication device 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 connection is wired, for example of the USB cable type (from the English “Universal Serial Bus” or “Universal Serial Bus” in French).

The mobile communication device 101 advantageously transmits data to one or more computers of the on-board system of the vehicle 10 with which the device 101 communicates and exchanges data. For example, the data transmitted by the device 101 are received by a telematic 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 carrying out various useful services for the correct operation of the vehicle. The computers communicate and exchange data with each other via one or more computer buses, for example a communication bus of the CAN data bus type (from the English “Controller Area Network” or in French “Réseau de Contrôleur "), CAN FD (from the English "Controller Area Network Flexible Data-Rate" or in French "Réseau de Contrôleurs à Flow de Data Flexible"), FlexRay (according to the ISO 17458 standard) or Ethernet (according to the ISO/ IEC 802-3).

According to a particular embodiment, a software module configured to establish wireless communication with the mobile communication device 101 is installed on the IVI computer, allowing the IVI computer to manage the data streams received from the mobile communication device 101 for a display of the content displayed on the screen of the device 100 on the screen 100.

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.

According to a particular embodiment, the display screen 100 (for example via the IVI computer controlling the display screen 100) and the mobile communication device 101 are configured to implement a so-called duplication technology. screen (“screen mirroring”) 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( s) 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 (c that is to say the on-board system of the vehicle 10, including the computer IVI 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.

According to another example, the mobile communication device 101 is used as a touch interface to control the infotainment system of the vehicle 10, for example via a graphical human-machine interface (HMI) displayed on the screen of the mobile communication device 101. The commands entered by a user via the screen of the mobile communication device 101 are transmitted to the computer in charge of the IVI system of the vehicle so that the latter controls the execution of the function or functions controlled by the user.

An example of implementation of a process for controlling an IVI system of the vehicle 10 via a screen associated with this IVI system (for example linked to the computer in charge of the IVI system via a wired connection or a wireless connection) is described in more detail with reference to Figures 2, 3 and 4 below.

There schematically illustrates a display device 2 embedded in the passenger compartment of the vehicle 10, according to a particular and non-limiting embodiment of the present invention.

The device 2 corresponds for example to the mobile communication device 101. According to another example, the device 2 corresponds to a display device integrated for example in the dashboard of the vehicle 10.

The device 2 comprises a screen 20, advantageously touch-sensitive. This screen 20 comprises a plurality of zones 21 to 25, a zone corresponding to a part of the surface formed by the screen for displaying graphic content, each zone being dedicated to the display of content of an MMI allowing a user to interact with the IVI system of the vehicle 10 and to control it.

A part of these areas 21 to 24 each correspond to a touch button associated with a specific function controlled by the IVI system of the vehicle 10. Pressing one of these areas 21 to 24 thus makes it possible to activate and/or control a function determined controlled by the IVI system of the vehicle 10.

For example, zones 21 to 24 form a strip in the lower part of screen 20, this strip being subdivided into as many zones as there are functions controlled by the IVI system.

For example, 4 touch buttons 21 to 24 are defined respectively on 4 zones of the screen dedicated to this purpose, an icon representing the function associated with each of these touch zones 21 to 24 being displayed on each zone 21 to 24 defined by the HMI.

Each zone 21 to 24 is provided for accessing a particular universe or environment of the IVI system, with each universe or environment being associated with a particular function, for example a multimedia content rendering function, a road navigation function, a communication and/or Internet browsing function.

For example, a first zone 21 is associated with a first function, corresponding for example to a home page of the MMI making it possible to control the IVI system.

A second zone 22 is for example associated with a road navigation function whose display of associated information (road map, icon representing the position of the vehicle 10, route layout, etc.) is managed by the IVI system.

A third zone 23 is for example associated with a multimedia content rendering function, for example for rendering music from one or more sources, for example the radio, one or more mobile applications of a digital music distribution platform ( such as Deezer®, Spotify® or others), a storage area for audio files, for example stored on a memory medium such as a USB key (from the English "Universal Serial Bus" or in French "Bus serial universal”) for example.

A fourth zone 24 is for example associated with a communication function to allow a user to telephone or to send and receive messages such as SMS (from the English "Short Message Service" or in French "Minimessages Service") For example.

A fifth zone, not shown, is for example associated with an Internet browsing function, for example via a browser that can be selected from among a plurality of browsers.

A zone 25 of the screen, for example located above the strip comprising the control zones 21 to 24, is for example also provided for displaying the graphic pages of the HMI making it possible to control each function of the IVI system associated with one of buttons 21 to 24.

One or more additional areas 26, 27 of the screen are optionally provided to allow access to additional pages or menus of the HMI, for example to control the parameters of the HMI (access to control these parameters being obtained by pressing or clicking on the icon 26) or to execute a voice command service by pressing or clicking on the icon 27.

Of course, other areas not shown on the can be provided on the screen for control or interactivity with other options or functions.

A process for controlling the IVI system of the vehicle 10 is advantageously implemented by one or more processors controlling the display of graphic content on the screen 2.

Such a process is described with reference to Figures 3 and 4.

In a first operation, the processor or processors receive first information representative of a first tactile press on a first zone of the screen 2, for example the zone 23 represented in gray for this purpose on the . The tactile support (also called "click") is for example performed by a user who presses with a finger the area 23 on which is displayed an icon representing for example a musical note, to illustrate that this area 23 allows access a multimedia content management function (for example to listen to music in the vehicle and/or watch a video).

The first piece of information corresponds for example to data describing the position of zone 23 on the screen.

In a second operation, the function controlled by the IVI system and associated with zone 23 is implemented or executed. The association is for example recorded in a correspondence table, called LUT (from the English “Look-Up Table”) matching the coordinates of each zone 21 to 24 with the associated function to be implemented, for each press touch on the area.

The execution of the associated function allows the user to access the universe or the environment associated with this function, in this case the multimedia content rendering function (also called universe or multimedia environment for example) for area 23.

The execution of this function triggers for example the rendering of the content listened to during the last visit of the user in this universe. For example, if the user was listening to a specific radio station the last time he or she used this function, then the execution of the function following the first click on zone 23 activates listening to this radio station. . According to another example, if the user was listening to a title belonging to a list of titles whose source corresponds for example to a digital distribution platform, then the reading of this list is resumed where it left off.

The execution of this function further comprises the display of a page or of a content of the MMI (on the area 25 of the screen dedicated to this purpose) corresponding to the function, for example the display of 31 icons associated with playing a piece of music (eg play, stop, skip to next piece, etc.). The user is thus able to control the rendering of the multimedia content in progress via the graphical interface displayed on zone 25.

When the device 2 corresponds to the mobile communication device 101, the content displayed on the zone 25 is duplicated on the screen 100 integrated into the dashboard of the vehicle 10, according to a particular and optional embodiment of the invention.

In a third operation, the processor(s) receive second information representative of a second touch press on the first zone of the screen 2 having received the first touch press, that is to say the zone 23 according to the example described represented in gray for this purpose on the . The tactile press (also called “click”) is for example performed by a user who presses the zone 23 with a finger after having accessed the multimedia content rendering function via the first press on this same zone 23.

The second information advantageously comprises the same data as the first information.

In a fourth operation, another page or other graphic content of the MMI is displayed on zone 25 of screen 2, this other graphic content being associated with the function associated with zone 23. This other graphic content of the IHM is advantageously provided to allow the user to access the control of one or more parameters of the multimedia content rendering function associated with zone 23.

The graphic content displayed comprises for example 4 zones or virtual buttons 41, 42, 43 and 44 allowing the user, for example, to select a source of multimedia content from among a plurality of sources, one source being associated with each virtual button 41 to 44 To this end, an icon or a text describing the source is for example displayed on each zone 41 to 44 so that the user selects the desired source.

Access to parameter control is triggered by the second press on the same virtual button 23 which allowed access to the function (or to the universe) associated with this virtual button 23. The parameters that can be controlled via the graphical interface displayed depend on the function implemented prior to the second operation.

Touching (or clicking) on another zone or virtual button allows the user to access another function controlled by the IVI system.

For example, a first tactile press on zone 22 makes it possible to implement the road navigation function and allows the user to access the road navigation universe, that is to say the parts of the HMIs dedicated to road navigation.

For example, a first press on zone 22 causes the execution of the mobile road navigation application last used by the user (for example the Waze® mobile application) and access to the HMI of this mobile application displayed on the zone 25 of the screen instead of the MMI of the function implemented previously, that is to say the setting of the multimedia content rendering function.

A second tactile press on this same zone 22 allows the user to access a page or content of the HMI configured to configure the road navigation function implemented following the first tactile press on zone 22. For example , the second press on zone 22 causes the display of a set of zones or virtual buttons making it possible to select another mobile application (for example Maps® from the company Google®).

In the same way, a first tactile press on zone 24 allows the user to access the communication function, for example to establish a telephone call or write and send one or more messages. The first tactile press allows for example to access the telephony function and a second tactile press on this same zone 24 allows access to a menu allowing to choose another communication option, for example the sending of an SMS .
