Method and device for controlling a system for displaying an accredited parameter of a vehicle

Abstract

The present invention relates to a method and device for controlling a system for displaying an accredited parameter of a vehicle. For this purpose, data representative of presses (302, 304, 306) on a control device (30) are successively received, and the display of graphical objects (322, 324, 326) representative of a trip counter 1 and of a trip counter 2 is controlled on a screen (12). This method makes it possible to recalibrate the display of an accredited parameter of a vehicle when the time that has elapsed between the successive presses is less than a certain threshold time.

Description

DESCRIPTION Title: Method and device for controlling a system for displaying an approved vehicle parameter technical field

[0001] The present invention claims priority from French application 2413992 filed on December 12, 2024, the content of which (text, drawings and claims) is incorporated herein by reference.

[0002] The invention relates to methods and devices for controlling a vehicle display system, particularly, but not exclusively, for a motor vehicle. The invention specifically relates to a method and device for controlling the display of graphic content representing a recalibration of an approved vehicle parameter. Technological background

[0003] Modern vehicles are equipped with advanced systems that display essential information to the driver, including parameters related to vehicle range, energy consumption, and battery charge level in the case of electric or hybrid vehicles. This information, usually presented on onboard digital displays, is crucial for enabling drivers to effectively plan their journeys and anticipate charging or refueling needs.

[0004] A vehicle's range display typically relies on algorithms integrated into the vehicle's energy management system. These algorithms estimate the range based on various parameters, such as instantaneous energy consumption, driving history, driver style, environmental conditions (temperature, topography, etc.), and battery charge level. While these estimates are accurate in many situations, they exhibit significant variations that can make it difficult for the driver or vehicle owner to compare the displayed range with the official range provided at the time of purchase.

[0005] This variation in the displayed range is particularly problematic, as it can generate inconsistencies between the actual consumption observed by the user and the theoretical or certified range. Indeed, the certified range value is Often calculated according to standardized homologation cycles, such as the WLTP (Worldwide Harmonized Light Vehicles Test Procedure), which do not necessarily reflect real-world driving conditions, drivers may experience significant discrepancies between the manufacturer's advertised or sold range and the range displayed on the dashboard. This can lead to misunderstandings, dissatisfaction, and a loss of confidence in the system.

[0006] Furthermore, current devices do not allow the driver or owner to easily or manually recalibrate the displayed range to align it with the certified or desired value. This limitation is compounded by the risk of confusion or error when recalibration attempts are made unintentionally or accidentally, due to the complexity of the control systems integrated into modern vehicles. Without suitable solutions, the user cannot effectively synchronize the displayed range with their expectations or with the manufacturer's reference data.

[0007] It is therefore necessary to develop a technical solution to overcome these limitations. Such a solution should offer the ability to display a certified range value, corresponding to the one sold to the customer or communicated by the manufacturer, while remaining consistent with the vehicle's actual consumption. It should also include a clear activation procedure, for example via the on-board computer (OBC), allowing the owner to manually recalibrate the displayed range without risk of unintentional activation. This process would guarantee an improved user experience by ensuring a reliable and transparent match between the displayed range data and the customer's expectations, while preserving the accuracy and flexibility necessary to account for variations in real-world driving conditions. Summary of the present invention

[0008] One object of the present invention is to solve at least one of the problems of the technological background described above.

[0009] One object of the present invention is to allow the display of an approved range value, corresponding to that sold to the customer or communicated by the manufacturer, directly on the vehicle's dashboard.

[0010] Another object of the present invention is to ensure consistency between the displayed range and the actual consumption of the vehicle, while preserving the readability and reliability of the information for the driver.

[0011] Another object of the present invention is to provide a clear and intuitive activation procedure enabling the vehicle owner to manually recalibrate the range displayed via the on-board computer, while avoiding any unintentional activation of said procedure.

[0012] Another object of the present invention is to improve the user experience by offering precise and accessible control of display parameters related to autonomy, ensuring greater satisfaction and a transparent understanding of vehicle performance.

[0013] Another object of the present invention is to minimize the risks of confusion or dissatisfaction related to discrepancies between actual consumption and theoretical autonomy, by providing a reliable technical solution adaptable to the user's needs.

[0014] Another object of the present invention is to ensure that the information displayed remains compliant with regulatory and commercial expectations, while offering sufficient flexibility to adapt to variations in real-world driving conditions.

[0015] According to a first aspect, the present invention relates to a method for controlling a display system for an approved parameter of a vehicle, said display system comprising a screen, said method being implemented by at least one processor and comprising the following steps: - display control of a first graphic content including a first graphic object representing a (non-approved) parameter of said vehicle; - receipt of initial data representative of an initial press on a control device; said initial data including initial information representative of a duration of press on said control device; - control of display of a second graphic content including a second graphic object representing a first journey counter when said first information is representative of a duration less than a first threshold duration; - reception of second data representing a second press on said control device; said second data including a second piece of information representing a duration of press on said control device; - display control, in said second graphic content, of a third graphic object representing a reset of said first trip counter when said second information is representative of a duration exceeding the said first threshold duration; - receipt of third data representing a third press on said control device; said third data including a third piece of information representing a duration of press on said control device; - display control, in said second graphic content, of a fourth graphic object representing a second journey counter when said third information is representative of a duration less than a second threshold duration; - receipt of fourth data points representing a fourth press on said control device; said fourth data points including a fourth piece of information representing a duration of press on said control device; - display control, within said second graphic content, of a fifth graphic object representing a reset of said second trip counter when said fourth information represents a duration exceeding said second threshold duration; and - display control, in said first graphic content, of a sixth graphic object representing an approved version of said parameter of said vehicle when the time elapsed between the reception of said first data and said fourth data is less than a third threshold duration, said sixth graphic object replacing said first graphic object.

[0016] Advantageously, the display of said sixth graphic object is not implemented when said vehicle includes a trailer or when a load state of said vehicle is less than a threshold value.

[0017] According to one variant, the said approved parameter corresponds to an approved mileage range of said vehicle or an approved consumption of said vehicle.

[0018] According to another variant, said screen is a touch interface screen and said control device is a graphic object displayed on said touch screen, said data receptions being representative of touch pressing on said control device.

[0019] According to yet another variant, the said first graphic content includes the said second graphic content.

[0020] According to a further embodiment, said third threshold duration is 30 seconds or less, in particular about 30 seconds. This threshold duration is in no way limiting of the invention and any duration, on the one hand, sufficiently long to allow the user to have the The time required to execute the recalibration procedure described here, and on the other hand, a sufficiently short time to prevent the user from inadvertently activating the recalibration, is particularly considered.

[0021] According to a second aspect, the present invention relates to a computer program which includes instructions adapted for the execution of the steps of the process according to the first aspect of the present invention, in particular when the computer program is executed by at least one processor.

[0022] Such a computer program can use any programming language, and be in the form of source code, object code, or an intermediate form between source code and object code, such as in a partially compiled form, or in any other desirable form.

[0023] According to a third aspect, the present invention relates to a computer-readable recording medium on which is recorded a computer program comprising instructions for carrying out the steps of the process according to the first aspect of the present invention.

[0024] On the one hand, the recording medium can be any entity or device capable of storing the program. For example, the medium can include a storage means, such as a ROM, a CD-ROM or a microelectronic circuit-type ROM, or a magnetic recording means or a hard drive.

[0025] On the other hand, this recording medium can also be a transmissible medium such as an electrical or optical signal, such a signal being able to be transmitted via an electrical or optical cable, by conventional or radio frequency, by self-directing laser beam, or by other means. The computer program according to the present invention can, in particular, be downloaded from a network such as the Internet.

[0026] Alternatively, the recording medium may be an integrated circuit in which the computer program is incorporated, the integrated circuit being adapted to execute or to be used in the execution of the process in question.

[0027] According to a fourth aspect, the present invention relates to a control device for a display system of an approved parameter of a vehicle, the device comprising a memory associated with a processor configured for the implementation of the steps of the process according to the first aspect of the present invention.

[0028] According to a fifth aspect, the present invention relates to a vehicle, for example of the automobile type, comprising a device as described above according to the fourth aspect of the present invention.

[0029] The invention therefore offers several significant advantages by allowing the display of a certified range value, consistent with the one sold to the customer or communicated by the manufacturer. This ensures greater transparency and strengthens customer confidence in the data provided by the vehicle, avoiding any misunderstandings related to discrepancies between the actual range and the advertised theoretical value.

[0030] Another advantage of this invention lies in the user's ability to manually recalibrate the displayed range via a clear and secure activation procedure on the on-board computer (OBC). This feature offers significant flexibility while reducing the risk of unintentional activation, thus ensuring simple and reliable use even for non-expert users.

[0031] The invention also improves the user experience by allowing better control over range display settings, thus contributing to greater driver satisfaction. It avoids the frustrations associated with fluctuating or seemingly inconsistent estimates by offering a technical solution that adapts to both the driver's practical needs and the requirements of homologation testing.

[0032] Furthermore, this invention helps to align the displayed range with the vehicle's actual energy consumption while also offering the option of showing the advertised theoretical value. This allows drivers to better understand their vehicle's energy performance and optimize their driving style or charging habits accordingly.

[0033] Finally, the invention also ensures regulatory compliance by facilitating access to the approved value, while maintaining the accuracy of real-world fuel consumption data. This dual functionality meets user expectations while enhancing the commercial relevance of the information provided by the vehicle. Brief description of the figures

[0034] Other features and advantages of the present invention will become apparent from the description of the specific and non-limiting embodiments of the present invention below, with reference to the attached Figures 1 to 6, in which:

[0040] [Fig. 6] illustrates a flowchart of the different steps of a process for controlling a display system of the vehicle of figure 1, according to a particular and non-limiting example of the present invention. Description of examples of achievements

[0041] A method and device for controlling a system for displaying an approved parameter of a vehicle will now be described in what follows with joint reference to Figures 1 to 6. The same elements are identified with the same reference signs throughout the description that follows.

[0042] The terms "first," "second" (or "firsts," "seconds"), etc., are used in this document by arbitrary convention to identify and distinguish different elements (such as operations, means, etc.) implemented in the embodiments described below. Such elements may be distinct or correspond to a single element, depending on the embodiment.

[0043] According to a particular and non-limiting example of an embodiment of the present invention, the control of a display system embedded in a vehicle is, for example, implemented by one or more computers in the vehicle, for example via one or more processors.

[0044] To this end, the display of initial graphical content, including a first graphical object representing a (non-approved) parameter of the vehicle, is controlled to ensure that this first graphical object is displayed on the screen, particularly a touchscreen. The display can be controlled in response to a user's touch, or, for example, in response to the vehicle being started.

[0045] Data representing an initial press on a control device is received. The control device may be a mechanical actuator, such as a push button, or a graphic object displayed on the touchscreen. This data includes initial information representing a certain duration of press on the control device that is less than a specified threshold duration. In a particular embodiment, this initial press is a short or brief press. A short or brief (in particular, touch) press corresponds to a non-prolonged and brief (touch) press of one or more fingers on a part of the control device (in particular, a part of the touchscreen), the short or brief press being of a duration less than a given threshold duration (for example, 2 seconds, in particular, 1 second).

[0046] In response to the first press, the display of a second graphic content including a second graphic object representing a first trip counter is controlled so that this second graphic object is displayed on the screen, in particular a touch screen, when said first information is representative of a duration less than the first threshold duration.

[0047] Data representing a second press on the control device is then received. This data includes a second piece of information representing a certain duration of press on the control device that exceeds the first threshold duration. In a particular embodiment, this second press is a long press. A long press (in particular, a touch press) corresponds to a continuous and prolonged (touch) press of one or more fingers on a part of the control device (in particular, a part of the touchscreen), the long press being longer than a given first threshold duration (for example, 2 seconds, in particular, 1 second) and can last, for example, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 seconds, depending, for example, on the user's intent.

[0048] In response to the second press, the display of a third graphic object representing a reset of the first trip counter is controlled so that this third graphic object is displayed on the screen, in particular a touch screen, when said second information is representative of a duration greater than said first threshold duration.

[0049] In a subsequent stage of the process, data representing a third press on a control device is received. This data includes a third piece of information representing a certain duration of press on said control device that is less than a second threshold duration. In a particular embodiment, said third press is a short or brief press.

[0050] In response to the third press, the display of a fourth graphic object representing a second trip counter is controlled so that this fourth graphic object is displayed on the screen, in particular a touch screen, when said third information is representative of a duration less than said second threshold duration.

[0051] Data representing a fourth press on the control device is then received. This data includes a fourth piece of information representing a certain duration of press on the control device exceeding the second threshold duration. In a particular embodiment, this fourth press is a long press.

[0052] In response to the fourth press, the display of a fifth graphic object representing a reset of said second trip counter is controlled so that this fifth graphic object is displayed on the screen, in particular a touch screen, when said fourth information is representative of a duration greater than said second threshold duration.

[0053] In a particular embodiment, said first threshold duration is identical to said second threshold duration, namely, for example, 2 seconds, in particular, 1 second.

[0054] The first trip odometer is often labeled "Trip 1" on the vehicle's dashboard display, and the second trip odometer is labeled "Trip 2." The Trip 1 and Trip 2 functions, found on the dashboards of electric cars, for example, are used to record and track data related to distances traveled and energy consumption, and offer several advantages in terms of trip management and analysis. These functions are sub-odometers, generally independent of the total odometer, allowing the user to monitor specific statistics for different purposes.

[0055] Trip 1 is typically used to measure data from a single trip or a short period, such as a daily commute. For example, it tracks distance traveled (in kilometers or miles), energy consumption (in kWh / 100 km), average speed, and driving time. This helps the user analyze energy efficiency on a specific journey, such as a round trip between home and work, and adapting one's driving style or charging choices to optimize the vehicle's range.

[0056] Trip 2 is often used to record data over a longer period or for a specific purpose, such as an extended trip or analyzing overall consumption over several days or weeks. This allows the user to compare vehicle performance in different contexts (urban, highway, etc.) or to plan charging based on observed consumption.

[0057] Both functions allow data to be reset at any time, offering complete flexibility for analyzing specific journeys or periods of use. This data can also be crucial for users who want to optimize their energy costs, track the environmental impact of their driving, or plan vehicle maintenance. In the case of electric cars, information on kWh consumption and energy efficiency allows for a better understanding of remaining range, anticipating charging needs, and improving overall vehicle energy management.

[0058] In a subsequent stage of the process, the display of a sixth graphic object representing an approved version of said parameter is controlled so that this sixth graphic object is displayed on the screen, in particular a touch screen, when the time elapsed between the reception of the first data and the fourth representative support data is less than a third threshold duration, said sixth graphic object replacing said first graphic object and resulting in the recalibration of the display of the parameter in its approved value.

[0059] In one particular embodiment, said third threshold duration is, for example, 15, 20, 25, 30, 35, 40, or 45 seconds and is in no way limiting to the invention. Preferably, a value of 30 seconds or close to it will be used.

[0060] Figure 1 schematically illustrates part of the passenger compartment of a vehicle 10, according to a particular and non-limiting embodiment of the present invention.

[0061] Vehicle 10 corresponds, for example, to a vehicle with an internal combustion engine or a hybrid vehicle with an internal combustion engine and one or more electric motors. In a particular embodiment, vehicle 10 is an electric vehicle. Vehicle 10 thus corresponds, for example, to a land vehicle, such as a car, a truck, or a bus.

[0062] Vehicle 10 advantageously incorporates a display system comprising a screen 12, preferably with a touchscreen interface, and a control unit configured to control the display of graphical HMI content on the touchscreen 12. This control unit corresponds, for example, to the instrument cluster control unit or ECU (Instrument Cluster ECU). This control unit is responsible for managing and displaying information on the vehicle's instrument cluster screen, which includes trip data, range, energy consumption, speed, and other essential vehicle parameters.

[0063] The computer collects the necessary data from other electronic control units of the vehicle 10, such as the engine management computer (ECU) for fuel or energy consumption information, the battery computer for state of charge (SOC) data in electric vehicles, and the speed and odometer sensors to measure distance travelled.

[0064] The instrument cluster control unit is often connected to the CAN (Controller Area Network) communication bus, which allows different control units to share necessary information. For example, it receives data from sensors via the engine or transmission control unit and transmits this information to the user via the controls or buttons located on the steering wheel or center console.

[0065] The 12-inch touchscreen corresponds, for example, to an LCD type screen (from the English "Liquid Crystal Display" or in French "Affichage à cristals liquide"), for example of the TFT type (from the English "Thin-Film Transistor" or in French "Transistor en film mince"), or OLED (from the English "Organic Light-Emitting Diode" or in French "Diode électroluminescente organique").

[0066] The touchscreen 12 is configured to display content for the driver and passengers of vehicle 10. The touchscreen 12 is also configured to allow the driver and / or passengers of the vehicle to interact with one or more systems embedded in the vehicle via a human-machine interface (HMI) displayed on the touchscreen 12.

[0067] According to a particular embodiment, the display system includes one or more other screens, for example a screen of a device or system called a head-up display, corresponding for example to a transparent or semi-transparent blade arranged in such a way that a driver seated in a seat 15 of the vehicle 10 sees the displayed content or projected onto the transparent blade when the driver drives the vehicle 10. The display system includes, for example, in addition a display screen called a combination or instrument panel and usually arranged in an area 13 behind the steering wheel 14 in the dashboard 16.

[0068] According to a particular embodiment, the display system including the touch screen 12 is for example provided or configured to reduce the number of screens present in the vehicle 10, allowing for example the removal of the display screen(s) called instrument cluster or instrument panel.

[0069] In a particular embodiment, the vehicle 10 incorporates one or more embedded systems, each controlled by one or more computers. These computers, together with the instrument cluster computer, form, for example, a multiplexed architecture for providing various services essential for the proper functioning of the vehicle and for assisting the driver and / or passengers in controlling the vehicle 10 through the control of the embedded system(s) within the vehicle 10.Computers communicate and exchange data with each other via one or more computer buses, for example a CAN data bus (from the English "Controller Area Network" or in French "Réseau de contrôlers"), CAN FD (from the English "Controller Area Network Flexible Data-Rate" or in French "Réseau de contrôlers à débit de données flexible"), FlexRay (according to the ISO 17458 standard), LIN (from the English "Local Interconnect Network" or in French "Réseau interconnecté local") or Ethernet (according to the ISO / IEC 802-3 standard).

[0070] A process for controlling a display system of an approved parameter in the vehicle 10 is advantageously implemented by one or more processors of the display system.

[0071] The control process is described in support of figures 2, 3 and 4, each of which illustrates the result of displaying one or more graphic objects on screen 12, according to different implementation examples.

[0072] In the first operation of the process, the display on screen 12 of a first graphic content 20 comprising a first graphic object 22 is controlled at a time t0. This first graphic object represents a parameter 24 of the vehicle 10, in particular a range in kilometers or a consumption of the vehicle 10.

[0073] The display of the first graphic object can be implemented by pressing on a dedicated actuation device or automatically when the vehicle 10 is put into operation.

[0074] The display of parameter 24 initially corresponds to the non-approved value of that parameter. For example, when an electric vehicle's battery is fully charged, the range calculation displayed on the dashboard follows a slightly different logic than the one used during driving. At full charge, the range prediction algorithm can no longer rely solely on recent consumption data, as this information is associated with previous driving conditions that may not reflect future conditions. Therefore, the range calculation at 100% is generally based on a predefined reference value that can be adjusted according to various parameters, including historical usage data.

[0075] Many vehicles therefore display a personalized range estimate based on the driver's driving history. To do this, the algorithm can analyze the average consumption of the last 50 or 100 trips, allowing it to adapt the estimate to the user's driving style. This method guarantees greater accuracy but can be misleading, as the range displayed immediately after a full charge may differ from the "sales promise" range, which is based on homologation standards (WLTP, NEDC, etc.).

[0076] As illustrated in Figure 1, the 100% range of the displayed vehicle 10 may be 420 km, which may differ from the approved range value presented at the time of purchase of the vehicle 10 and therefore be disappointing for the owner of said vehicle.

[0077] In a second operation of the process, and as illustrated in figure 3, initial data representing a first press 302 on a control device 30 are received at a time t1. Said initial data comprising initial information representing a duration of press on said control device 30.

[0078] When the first piece of information represents a duration shorter than a first threshold duration, the display of a second graphic content 32, comprising a second graphic object 322 representing a first trip counter, is controlled. Typically, the first threshold duration is set so that the press 302 corresponds to the duration of a short press and generally corresponds to a duration less than or equal to approximately 2 seconds, and in particular less than or equal to approximately 1 second. The short press can last 1 or 2 seconds or less, for example, provided it corresponds to a duration shorter than the set threshold. The first press 302 therefore displays a graphic object corresponding to an initial trip counter, which can provide information on the vehicle's last daily trip 10, such as the distance traveled, average speed, and average fuel consumption for that trip. This trip counter is generally referenced and labeled as "Trip 1" and is typically intended to provide the driver with driving data based on a generally short and recent trip.

[0079] In a third operation of the process, and as illustrated in Figure 3, second data representing a second press 304 on said control device 30 are received at time t2. Said second data include a second piece of information representing a duration of press on said control device 30.

[0080] When the second piece of information represents a duration greater than the first threshold duration, the display of a third graphic object 324, included within the second graphic content 32 and representing a reset of the first trip odometer, is controlled. Typically, the first threshold duration is set so that the press 304 corresponds to the duration of a long press and generally corresponds to a duration less than or equal to approximately 2 seconds, and in particular less than or equal to approximately 1 second. The long press can last 1, 2, 3, 4, or 5 seconds, for example, as long as it corresponds to a duration greater than the set threshold duration. The second press 304 therefore resets the display of the first trip odometer, with the distance traveled, average speed, and average fuel consumption for this last trip all showing initial values.

[0081] In a fourth operation of the process, and as illustrated in figure 3, third data representing a third press 306 on said control device 30, are received at a time t3. Said third data include a third piece of information representing a duration of press on said control device 30.

[0082] When said third piece of information represents a duration less than a second threshold duration, the display of a fourth graphic object 326, representing a second trip counter, is controlled in said second graphic content 32. Typically, said second threshold duration is set so that the press 306 corresponds to the duration of a short press and generally corresponds to a duration less than or equal to approximately 2 seconds, and in particular less than or equal to approximately 1 second. The short press can last 1 or 2 seconds or less, for example, provided it corresponds to a duration shorter than the set threshold. The third press 306 therefore allows the display of a graphic object corresponding to a second trip counter, which can provide information, for example, on the cumulative total of the last daily trips made by vehicle 10, such as the distance traveled, average speed, and average fuel consumption achieved over all these trips. This trip counter is generally referenced and labeled as "Trip 2" and is typically intended to provide the driver with driving data based on a longer trip than trip 1 or on a number of trips made over a weekly or monthly period, for example.

[0083] In a fourth operation of the process, and as illustrated in Figure 4, fourth data points representing a fourth press 308 on said control device 30 are received at time t4. Said fourth data points include a fourth piece of information representing a duration of press on said control device 30.

[0084] When the fourth piece of information represents a duration exceeding the second threshold duration, the display of a fifth graphic object 328, representing a reset of the second trip odometer, is controlled within the second graphic content 32. Typically, the first threshold duration is set so that the press 308 corresponds to the duration of a long press and generally corresponds to a duration less than or equal to approximately 2 seconds, and in particular less than or equal to approximately 1 second. The long press can last 1, 2, 3, 4, or 5 seconds, for example, as long as it corresponds to a duration greater than the set threshold duration. The fourth press 308 therefore resets the display of the second trip odometer, with the distance traveled, average speed, and average fuel consumption recorded on this trip(s) all showing initial values.

[0085] In a particular embodiment, the said first and second threshold durations are identical.

[0086] In a fifth operation of the process, and as illustrated in figure 4, the display of a sixth graphic object 330 representing an approved version of said parameter 24 of said vehicle 10 is checked at a time t5 in said first graphic content, when the time elapsed between the reception of said first data and said fourth data is less than a third threshold time, said sixth graphic object 330 replacing said first graphic object 22.

[0087] In one particular embodiment, said third threshold duration is 60 seconds or less, in particular 30 seconds or less, and particularly approximately 30 seconds. This threshold duration is in no way limiting; it must, on the one hand, allow a user sufficient time to perform the display and reset sequence of trip counters 1 and 2, but must also prevent any inadvertent recalibration of said parameter to its approved value.

[0088] Thanks to the present invention, a vehicle owner can easily recalibrate a parameter such as range or fuel consumption to its homologation value through a simple manipulation sequence. This can be useful if the vehicle needs to be returned to the showroom for display or sale.

[0089] In one particular embodiment, the display of said sixth graphic object 330 is not implemented when said vehicle 10 includes a trailer or when the load state of said vehicle 10 is below a threshold value. This function aims to prevent unexpected or misleading behavior for the driver.

[0090] In another particular embodiment, said approved parameter corresponds to an approved mileage range of said vehicle 10 or an approved consumption of said vehicle 10.

[0091] In a particularly advantageous embodiment, said screen 12 is a touch interface screen and said control device is a graphic object displayed on said touch screen, said data receptions 61, 63, 65, 67 being representative of touch pressing on said control device 30.

[0092] In one variant, said first graphic content includes said second graphic content and all graphic objects are displayed on different parts of the same screen 12.

[0093] Figure 5 schematically illustrates a device 5 configured for controlling a display system of a vehicle's approved parameter, for example, vehicle 10, according to specific and non-limiting embodiments of the present invention. The device 5 corresponds, for example, to a device embedded in the vehicle 10, such as a computer.

[0094] Device 5, for example, is configured to carry out the operations described opposite Figures 1 to 4 and / or the steps of the process described opposite Figure 6. Examples of such a device 5 include, but are not limited to, embedded electronic equipment such as a vehicle's on-board computer, an electronic control unit such as an ECU (Electronic Control Unit), a smartphone, a tablet, or a laptop computer. The elements of the device 5, individually or in combination, may be integrated into a single integrated circuit, into several integrated circuits, and / or into discrete components. The device 5 may be implemented as electronic circuits, software (or computer) modules, or a combination of electronic circuits and software modules.
