In particular, it seeks to provide a solution for minimizing the time a driver spends customizing the display of visual content in the vehicle during journeys to meet the preferences of a passenger present in the vehicle during those journeys. Through this means, the invention aims to enable the provision of more ergonomic and comfortable motor vehicles.

[0004] In order to achieve these goals, the invention relates, according to a first aspect, to a management method, using a computer device embedded on board a motor vehicle, displaying visual content in the vehicle, the process includes the following steps: • determine whether a route is stipulated in a vehicle navigation system; and, when it is established that this is the case, • cause the display of visual content in the vehicle according to a first display mode when it is established that data characterizing a specification of the presence of a passenger in the vehicle during the completion of the journey carried out by means of a communicating device remote from the vehicle have not been transmitted to the vehicle or according to a second display mode when it is established that data characterizing a specification of the presence of a passenger in the vehicle during the completion of the journey carried out by means of the communicating device have been transmitted to the vehicle.

[0005] According to one variant, the first display mode may consist of displaying a first set of visual content on the entire display area of ​​a screen and / or a head-up display device of the vehicle and the second display mode may consist of displaying a second set of visual content on a first portion of the display area of ​​the screen and / or the head-up display device and a third set of visual content on a second portion of the display area of ​​the screen and / or the head-up display device.

[0006] According to another variant, the first set of visual content, the second set of visual content and the third set of content may each include at least one interactive element.

[0007] According to yet another variant, the interactive element can be a widget or an icon enabling the execution of an application provided by a vehicle infotainment system.

[0008] According to a second aspect, the invention relates to a device for managing the display of visual content in a motor vehicle, the device comprising at least one information processing unit, including at least one processor, and a data storage medium configured to implement a method as described above.

[0016] [Fig.4] illustrates the implementation of at least one step of the process according to the invention. Detailed description of the invention

[0017] Figure 1 schematically illustrates a motor vehicle 1 according to the invention. This vehicle is conventionally equipped with a human-machine interface comprising at least one screen 2 for displaying visual content on a display surface of the screen 2. Preferably, the vehicle 1 also includes a head-up display 3, which commonly allows the display of visual content on a display surface located at the level of the vehicle's windshield. It also includes a navigation system 4, which conventionally allows the setting of routes and the display of visual content on the display surface of the screen 2 and / or the head-up display 3. Furthermore, it is equipped with a radio frequency signal communication system 5 in order to be able to communicate (i.e., transmit and receive data) using conventional mobile communication networks and protocols (e.g.V2X, ITS-G5, 3 / 4 / 5G) with remote communicating entities, in particular to receive data that is transmitted by a remote communicating device 6 from vehicle 1, for example a smartphone that runs an application dedicated to communication with vehicle 1. .

[0018] Advantageously, the vehicle 1 according to the invention also includes a device 100 for managing the display of visual content in a motor vehicle within the meaning of the present invention, as described below, which implements a method for managing the display of visual content in a motor vehicle within the meaning of the present invention, as briefly summarized below and described in detail below.

[0019] During the implementation of the method according to the invention, the device 100 according to the invention first determines whether a route is stipulated in the navigation system 4. And when it establishes that this is the case, it proceeds by determining whether data specifying the presence of a passenger in the vehicle 1 during the execution of this route have been previously transmitted to the vehicle 1. Advantageously, such data are indeed generated and transmitted to the vehicle 1 When the driver of vehicle 1 operates a communicating device 6, for example a smartphone running an application that allows communication with vehicle 1, the driver can remotely indicate the presence of a passenger during certain journeys. For example, the driver can indicate that a passenger is present in vehicle 1 during a journey between a residence and a school. Then, the device 100 according to the invention manages the display of visual content in vehicle 1 according to a first display mode if data indicating the presence of a passenger in the vehicle during the journey has not been transmitted to vehicle 1, or according to a second display mode if such data has been transmitted to vehicle 1.Advantageously, the first display mode consists of displaying visual content across the entire display area of ​​screen 2 or head-up display unit 3, while the second display mode consists of displaying visual content on a first portion of the display area of ​​screen 2 and / or head-up display unit 3 and visual content on a second portion of the display area of ​​screen 2 and / or head-up display unit 3. In other words, when it is specified that a passenger is present in the vehicle during the execution of a route programmed in the navigation system 4, the display area of ​​screen 2 and / or head-up display unit 3 is then divided into two parts and visual content, identical or different, is displayed on each of these parts.Thus, the driver no longer needs to customize the display of visual content in vehicle 1 to satisfy the preferences of a passenger who is present in the vehicle during the same journey. In this way, device 100 according to the invention prevents the driver from wasting time and thus contributes to making vehicle 1 according to the invention more ergonomic and comfortable.

[0020] The device 100 for managing the display of visual content in a motor vehicle according to the invention is illustrated in [Fig.2]. It is essentially a computer device, which includes at least one information processing unit 101, comprising one or more processors, a data storage medium 102, on which is recorded in particular a program which includes program code instructions for the execution of the steps of the process according to the invention described below, and an input and output interface 103 allowing the reception and transmission of data.

[0021] Preferably, the device 100 according to the invention is hosted on an independent computer and interacts via its input and output interface 103 and by means of a wired vehicle communication network (e.g., CAN, Ethernet, MOST) - represented in [Fig. 1] by the double-direction arrows - with the screen 2, with the head-up display unit 3, with the navigation system 4 and with the radio frequency signal communication system 5. Alternatively, the device 100 according to the invention is part, in whole or in part, of one or more of these components of the vehicle 1. As a result, the device 100 according to the invention can, in particular, determine whether a route is stipulated in the navigation system 4, it can determine whether data is transmitted to the vehicle 1 and it can cause the display of visual content on a display surface of the screen 2 and / or the head-up display unit 3.

[0022] According to the invention, all the elements described above contribute to enabling the implementation of a method for managing the display of visual content in a motor vehicle, as described below in relation to figures 3 and 4.

[0023] Figure 3 illustrates, by means of a flowchart, the steps of the method according to the invention. According to a first step 301 of the method according to the invention, the device 100 of the invention determines whether a route is programmed in the navigation system 4 of the vehicle 1. To do this, it interacts with the navigation system 4, for example, by continuously monitoring route stipulations that are carried out. And when it establishes that such a situation occurs, in other words, that a route is programmed in the navigation system 4, the device 100 of the invention proceeds by carrying out the next step of the method according to the invention described below.

[0024] According to a second step 302 of the method according to the invention, the device 100 according to the invention causes the display of visual content in the vehicle according to a first display mode when it establishes that data characterizing a specification of the presence of a passenger in the vehicle during the completion of the journey carried out by means of the communicating device 6 have not been transmitted to the vehicle 1, or according to a second display mode when it establishes that data characterizing a specification of the presence of a passenger in the vehicle during the completion of the journey carried out by means of the communicating device 6 have been transmitted to the vehicle 1.In other words, the device 100 according to the invention manages, at this stage, the display of visual content in the vehicle 1 in two different ways, depending on data concerning specifications of a passenger's presence during journeys. These specifications are advantageously generated remotely by means of the communicating device 6 and transmitted to the vehicle 1 via its radio frequency communication device 5 and mobile communication networks. The communicating device, for example, runs an application dedicated to the remote configuration of the vehicle's operation and its components. Such an application provides the driver with a graphical interface that allows them to specify journeys and enter the presence of an occupant for each specified journey. Such a graphical interface may, for example... to allow the specification and visualization of routes by means of a map, by interacting for example with a third-party application that allows geolocation.

[0025] Preferably, the first display mode that the device 100 according to the invention uses consists of displaying a first set of visual content on the entire display area of ​​the screen 2 and / or the head-up display unit 3. Thus, when data characterizing a specification of the presence of a passenger in the vehicle during the journey have not been transmitted to the vehicle 1, which means a priori that only the driver is in the vehicle 1 during the journey (or that a wish to personalize the display according to the presence of a passenger has not been specified), the device 100 according to the invention commands the display of visual content on the entire display area of ​​the screen 2 and / or the head-up display unit 3.This advantageously allows for better readability of the displayed visual content and, potentially, greater ease of interaction with it. Conversely, the second display mode used by the device 100 according to the invention consists of displaying a second set of visual content on a first portion of the display surface of the screen 2 and / or the head-up display unit 3 and a third set of visual content on a second portion of the display surface of the screen and / or the head-up display unit 3.In other words, the second display mode, which is advantageously used when the presence of a passenger during the journey has been specified by means of the communicating device 6, results in the display area of ​​the screen 2 and / or the head-up display 3 being divided into two portions, of identical or different sizes, in order to display two sets of visual content, identical or different. This advantageously allows visual content to be displayed for both the driver and the passenger.

[0026] These two display modes used by the device 100 according to the invention are schematically illustrated in [Fig. 4], with the first display mode (Mode 1) shown on the left and the second display mode (Mode 2) on the right. In both cases, the sets of content displayed on the display surface of the screen 2 and / or the head-up display unit 3 may contain at least one interactive element, for example, a widget or an icon enabling the execution of an application provided by a vehicle infotainment system 1, in particular by taking advantage of a touch interaction functionality of the screen 2.

[0027] Thus, thanks to the method and device according to the invention described above, a solution exists to minimize the time that a driver of a motor vehicle must allocate to personalizing the display of visual content in the vehicle during journeys in order to satisfy the preferences of a passenger who is present in the vehicle during these journeys. In this way, the method and device according to the invention enable the provision of more ergonomic and comfortable motor vehicles.
