Description

DEVICE FOR PROVIDING A GRAPHICAL INTERFACE IN A

VEHICLE WITH AT LEAST ONE REGULATORY WIDGET.

The invention relates to graphical interfaces, and in particular to customizable vehicle handsets.

Conventionally composed of a plurality of analog dials with needles associated with indicator lights, the combined instruments are used to provide the driver with a multitude of data relating to the operation of a motor vehicle, such as for example, instantaneous speeds and average, engine speed, number of kilometers traveled since the start or over a specified period of time, fuel level, or even average consumption. They also make it possible to display warning signals (excessive engine temperature, insufficient oil level, door not or poorly closed, seat belt not fastened, etc.) and warning lights signaling the activation of certain vehicle devices ( turn signals, handbrake, position, low beam or main beam).

These combined instruments, integrated into the dashboard of the vehicle, are usually arranged behind the steering wheel in the direct line of sight of the driver, so that the latter can consult the information displayed without having to look away from the road.

In recent years, fully digital instrument sets have appeared with an active matrix LCD display screen (LCD-TFT) instead of analog needle dials.

These handsets of a new type which offer a very good image quality in terms of resolution, contrast and brightness, are moreover configurable by the driver of the vehicle who can thus choose at least in part the modules he wishes. see displayed on the screen as well as the display style (dials with hands similar to analog dials or display in the form of graduations or numbers reflecting the value of the quantity concerned) and the ambiance of the handset (sober with dark colored lighting background, or sporty with bright colored lighting background).

These digital handsets also make it possible to control a certain number of vehicle functions (air conditioning, audio system, central locking, lighting, etc.) via controls located on the steering wheel or remote at the center console of the vehicle.

Current handsets do not really offer the possibility of customizing the display of driver information. The consequence is that certain information not of interest to the driver can be displayed and degrade the display synthesis and in particular the density of information.

Furthermore, when settings are available, the multitude of data that can be displayed and the variety of possible options, make the setting of these handsets relatively complex, in particular for a neophyte user.

Document EP2927791 discloses a method for configuring a widget displayed in a handset from a touch screen. However, customization is relatively limited. Some of the information displayed on the handset cannot be configured. In particular, two meters located on either side of a central screen are used to display the vehicle speed and the engine rotation frequency and thus meet a regulatory constraint.

One of the objectives of the invention is to remedy the aforementioned problem. The invention therefore aims to provide a device for providing a graphical vehicle interface for advanced personalization of the handset while being simple to handle and while ensuring compliance with regulatory constraints related to a display on a handset vehicle.

To this end, it more specifically proposes a device for providing a graphical interface in a vehicle, configured to control the display of a plurality of graphical data display objects called “widgets” on a handset screen, characterized in this includes a widget permanently displayed, when the first handset screen is on, said widget displaying at least the speed of the vehicle.

The invention makes it possible to comply with the regulatory constraints linked to a display on a combined vehicle by forcing the permanent display of a dedicated widget.

Advantageously, the device for providing a graphical interface according to the invention is, moreover, configured to control the successive display of a plurality of pages on the first screen, in response to a command from a user, each of the pages comprising at least the regulatory widget.

Advantageously, the device for providing a graphical interface according to the invention is also configured to command the display of at least one editing page on a second screen, the editing page comprising a representation of the widgets displayed on the first screen and a representation of free spaces to add new widgets. These free spaces can be placed anywhere on the first screen.

Advantageously, the editing page displayed on the second screen comprises a plurality of thumbnails for previewing pages displayed on the first screen, each of the thumbnails representing a simplified version of the page with which it is associated, and indicating a position of the regulatory widget. in the page associated with said thumbnail.

Advantageously, the device for providing a graphical interface according to the invention is, moreover, configured to authorize the removal of widgets from the page with the exception of said widget displayed permanently.

Advantageously, on the editing page displayed on the second screen, each widget, with the exception of the regulatory widget, is associated with a graphic object making it possible to delete said widget, the device being configured to delete the widget in response to detection. of a command on said graphic object associated with said widget.

Advantageously, each widget, with the exception of the regulatory widget, being able to be moved to a space of smaller size, the device being configured to move a widget in response to the detection of a command on said widget.

The invention also relates to a vehicle comprising a first and a second screen characterized in that it comprises a device according to any one of the preceding claims.

Other characteristics and advantages of the invention will appear on examining the detailed description below, and the attached drawings, in which

- Figure 1 illustrates a vehicle interior adapted to the implementation of the invention;

- Figures 2a and 2b respectively illustrate examples of displays on the first and second screen;

- Figure 3 illustrates the detail of a plurality of preview thumbnails on the editing page;

- Figure 4 illustrates a second example of display on the second screen.

The accompanying drawings may not only serve to complete the invention, but also contribute to its definition, if necessary.

Figure 1 shows a vehicle interior and in particular a dashboard. The dashboard comprises, on the driver's side, which is in the example shown on the left side of the vehicle, an instrument cluster 11.

The dashboard also includes, in a central part, a second screen 12. It is advantageously a touch screen.

The device according to the invention makes it possible to provide a graphical interface in the vehicle. It is in particular configured to control the display on the first 11 and on the second 12 screen and, in particular to control the display of a plurality of graphical data display objects called “widgets” on the first screen 11 and at least one edit page on the second screen 12.

The invention makes it possible to personalize display modes of a first screen, in particular a handset. If the user wishes, he can edit the display mode of his handset by changing customizable areas called "widgets". The handset is capable of displaying several widgets, comprising several sizes and which can represent the different functional areas available (Navigation, ADAS, Driving, Media, etc.). The user can choose and arrange them as they see fit.

FIG. 2a shows an example of a display of a plurality of widgets on the first screen 11 and of a corresponding editing page on the screen 12.

In this example, the first screen 11 displays:

- A first widget 21.1 displaying data relating to the fuel level of the vehicle,

- A second widget 21.2 displaying data relating to a distance separating the vehicle from a vehicle preceding it,

- A third widget 21.3 displaying information such as a speed of movement of the vehicle, a speed limit value for the speed limiter, a speed limit detected on the road segment traveled by the vehicle, and

- A fourth widget 21.4 displaying guidance information.

The third widget 21.3 displays so-called regulatory information because their display is constrained by certain regulations. We can cite as an example the speed of movement of the vehicle, speed limiter, flashing reminders of warning lights, headlight indicators, etc.

The regulatory information displayed in this widget can be adapted according to various national laws.

Figure 2b shows an example of a display of an edit page. The corresponding editing page displayed on the second screen 12 includes a representation 21 '. 1.21'. 2, 21 '. 3, 21'. 4, widgets 21.1, 21.2, 21.3, 21.4, displayed on the first screen 11. It also includes a representation of free spaces 22'.1,22'.2, 22'.3, 22'.4 to add new widgets.

These free spaces 22’.1, 22’.2, 22’.3, 22’.4 are indicated by graphic elements delimiting said free spaces. In the example, this is a border, surrounding each of said spaces.

It can be noted that said graphic elements delimiting spaces are absent from the first screen 11.

The device is configured to successively display a plurality of pages on the first screen 11. Each of the pages comprises at least the regulatory widget. This feature ensures that regulatory information is always displayed on the handset even if the driver changes the display of the handset.

The position of the widget on the different pages is not necessarily the same. This position can be modified by the user.

Advantageously, the edit page displayed on the second screen 12 comprises a plurality 30 of page preview thumbnails displayed on the first screen 11. Each of the thumbnails represents a simplified version of the page with which it is associated. Advantageously, each of the thumbnails indicates the position of the regulatory widget in the page associated with said thumbnail.

FIG. 3 shows the detail of an example of a plurality 30 of display thumbnails.

A first thumbnail 31.1 represents the page being viewed on the first screen 11. A second thumbnail 31.2 and a third thumbnail 31.3 represent two other pages available for display.

Each of the thumbnails has a plurality of rectangles. These rectangles represent a widget or an available space for a widget. The user can quickly find out the layout of the widgets on the corresponding page.

Advantageously, each rectangle has a graphical indication indicating whether it represents a widget, a free space or the regulatory widget.

In the example, the black rectangles represent the widgets, the rectangles represent the free spaces, and the striped rectangle represents the regulatory widget. It can be noted that each of the vignettes 31.1, 31.2, 31.3. has a striped rectangle. In other words, each page displayed on the first screen 11 includes a regulatory widget. This color code is not mandatory, it could be other colors or other graphic indications such as transparency or highlighting effects.

Advantageously, on the editing page displayed on the second screen 12, each widget 21 '.1,21'.2, 21'.4, with the exception of the regulatory widget, 21'.3, is associated with an object graph 23 '. 1, 23'.2, 23'.4 allowing to delete said widget 21'.1, 21'.2, 21 '.4, the device being configured to delete (from the first 11 and from the second 12 screen) the widget by response to the detection of a command on said graphic object 23'.1,23'.2, 23'.4 associated with said widget 21 '.1,21' .2, 21 '.4.

This feature ensures that the user cannot delete the regulatory widget and that the edited page remains in compliance with regulatory requirements.

In the example, each widget that can be deleted (in other words, whose display can be interrupted) is associated with a graphic object, represented in the example by a circle with a cross displayed in the upper right corner of the widget, but it could be another symbol placed in another place.

According to a characteristic of the invention, the device is configured to, in response to the detection of a scanning gesture from a first position, on which a widget is displayed, to a second position corresponding to a free space, control a movement of the widget, on the first 11 and on the second 12 screen, from the first position to the second position.

Advantageously, each widget, with the exception of the regulatory widget, is capable of being moved to a space of smaller size, the device being configured to move a widget in response to the detection of a command on said widget.

In the example in Figure 4, the edit page has three free spaces 42.1,42.2, 42.3. The first free space 42.1 has a size larger than that of the second 42.2 and third 42.3 free spaces arranged at the bottom of the editing page.

The device according to the invention is configured to authorize a displacement of the regulatory widget 41 to the first free space 42.1 (the size of which is equal to the size of the regulatory widget), and to prohibit a displacement of the regulatory widget to the second 42.2 and third 42.3 free spaces (the size of which is smaller than that of the regulatory widget 41).

This feature allows regulatory information to be displayed at a size large enough to be readable by the driver.

The handset (called first screen 11) has several display modes (or pages). The modes can be changed for example via a steering wheel control.

One of the information areas (widget), containing regulatory driving information, is displayed in each display mode (or page).

Only its position can be personalized.

The other widgets are freely customizable by the user. The user can select these widgets from a predefined widget library.
