Description

Title of the invention: Method and device for controlling a vehicle display system comprising an odometer technical field

[0001] The invention relates to methods and devices for controlling a display system in a vehicle, particularly, but not exclusively, a motor vehicle. The invention specifically relates to a method and device for controlling the display of information related to the use of a vehicle. The invention also relates to a method and device for assisting the driver in a vehicle. Technological background

[0002] Contemporary vehicles include, for some of them, several screens to display information useful to the driver for driving the vehicle as well as comfort information, such as, for example, information to interact with the infotainment system, also called IVI system (from the English "In-Vehicle Infotainment" or in French "Infodivertissement étoilé"), of the vehicle.

[0003] Among these screens, it is known to include one or more LCD type screens (from the English "Liquid Crystal Display" or in French "Affichage à cristals liquide"), for example of type TFT (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").

[0004] The integration of such screens makes it possible, for example, to control, via a graphical Human-Machine Interface (HMI) displayed on such screens, the operating status of the systems on board the vehicle, for example AD AS systems (from the English "Advanced Driver-Assistance System" or in French "Système d'aide à la conduite avancé").

[0005] The increasing number of embedded systems in the vehicle and the proliferation of means for controlling these systems lead to a greater complexity in the vehicle's interface. This complexity arises when a user interacts with the embedded systems to control them, particularly through a proliferation of icons, displayed messages, and command shortcuts, the control and management of which are consequently complicated for the user. The user experience is thus degraded, and the driver's attention may be reduced when various messages are displayed on the vehicle's screen(s).

[0006] Thus, information relating to vehicle use, such as the distance travelled obtained from the vehicle's odometer, is now displayed on a screen such as than a vehicle's dashboard. This information is limited and accessing it can be unintuitive. Summary of the present invention

[0007] One object of the present invention is to solve at least one of the problems of the technological background described above.

[0008] Another object of the present invention is, for example, to improve the user experience with regard to feedback on the use of the vehicle.

[0009] Another object of the present invention is, for example, to facilitate access to information relating to the use of a vehicle.

[0010] According to a first aspect, the present invention relates to a method for controlling a display system of a vehicle, the vehicle having an odometer, the display system comprising a touch screen, the method being implemented by at least one processor and comprising the following steps: - reception of initial representative data from at least one odometer reading; - control of displaying initial graphic content representing at least one odometer in a first area of ​​the touch screen based on the initial data; - reception of second data representing a first touch press on the first graphic content; - control of display of a second graphic content including at least a first statistical information on vehicle use over a first determined time interval following the reception of the second data, the second graphic content being displayed in a second area of ​​the touch screen.

[0011] Using a touchscreen on an area of ​​a screen displaying an odometer to request the display of additional content related to vehicle use over a specified period allows a person, for example the driver, to obtain additional information on demand concerning vehicle use. This makes it possible, for example, to monitor vehicle use and obtain information that allows, for example, an estimation of the vehicle's condition, in order to anticipate maintenance. Furthermore, all the content is displayed on a single screen, which facilitates access to information and minimizes the time spent searching for it. This improves driver alertness, as well as the safety of the vehicle and its passengers.

[0012] Centralizing controls on a single screen also eliminates the need for physical buttons to control vehicle operation, thereby reducing vehicle design and manufacturing costs.

[0013] According to one variant, the process further comprises the following steps: - reception of third data representing a touch scan on a part of the second graphic content; - control of display of a third graphic content in replacement of the second graphic content following the reception of the third data, the third graphic content including at least a second statistical information on vehicle use over a second determined time interval, the at least a second statistical information on vehicle use being different from the at least a first statistical information on vehicle use.

[0014] According to another variant, at least one first piece of statistical information on vehicle use and at least one second piece of statistical information on vehicle use belong to a set of information comprising: - information representative of a vehicle speed profile as a function of time over a time interval corresponding to the first determined time interval or the second determined time interval; - information representative of the average speed of the vehicle over the time interval; - information representative of the duration of vehicle use over the time interval; - information representing a distance travelled by the vehicle over the time interval; - information representative of the duration of vehicle use for each temporal subdivision of a set of temporal subdivisions forming the time interval; - information representing a distance traveled by the vehicle during each time subdivision of the set of time subdivisions; - information representative of a distribution of vehicle use according to at least one vehicle use criterion.

[0015] According to yet another variant, the first graphic content comprises a first diagram representing a history of the vehicle's speeds over the first determined time interval and a second diagram representing a histogram of the vehicle's monthly usage time over the first determined time interval, and The second graphic content includes a third diagram representing a day / night usage distribution of the vehicle, a fourth diagram representing a summer / winter usage distribution of the vehicle, and a fifth diagram representing a distribution of vehicle usage by type of environment.

[0016] According to a further embodiment, the process further comprises the steps following: - reception of fourth data points representing a second touch press on the first graphic content; - control of the end of display of a current graphic content corresponding to the second graphic content or the third graphic content following the reception of the fourth data.

[0017] According to a second aspect, the present invention relates to a control device for a vehicle display system, 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.

[0018] According to one variant, the device corresponds to a mobile communication device connected wirelessly to the vehicle.

[0019] According to a third aspect, the present invention relates to a vehicle, for example of the automobile type, comprising a device as described above according to the second aspect of the present invention.

[0020] According to a fourth aspect, the present invention relates to a computer program which includes instructions adapted for carrying out 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.

[0021] Such a computer program may use any programming language, and be in the form of source code, object code, or an intermediate code between source code and object code, such as in a partially compiled form, or in any other desirable form.

[0022] According to a fifth 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.

[0023] 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 disk drive.

[0024] 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 an Internet-type network.

[0025] 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. Brief description of the figures

[0026] 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:

[0033] A method and a control device for a vehicle display system 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 following description.

[0034] The terms "first," "second" (or "firsts," "seconds"), etc., are used in this document by arbitrary convention to allow for the identification and distinction of 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.

[0035] 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 of the vehicle, for example via one or more processors.

[0036] To this end, the display of initial graphic content representing one or more odometers is controlled so that this initial graphic content is displayed in a first area of ​​a touchscreen of the vehicle's display system. An odometer records the distance traveled by a vehicle, for example, the distance traveled since the vehicle was first registered (also called the total odometer), the distance traveled by the vehicle since the last odometer reset (for a so-called partial odometer), or the distance traveled by the vehicle since the start of a current journey (partial odometer). The data displayed in the initial graphic content is based on initial data obtained or received from the vehicle's pedometer.The vehicle's odometer is a system configured to measure the distance (for example, in meters or kilometers) traveled by the vehicle. The odometer includes, for example, a computer that determines the distance from data received from sensors associated with one or more of the vehicle's wheels, each sensor measuring the number of rotations made by a wheel.

[0037] Second data representing a touch press on the first graphic content are received from the touch interface, for example when a user makes a touch press on the touch screen at the display location of this first graphic content.

[0038] Following the reception of the second data, the computer controls the display of a second graphic content including statistical information relating to the use of the vehicle over a determined time period in a second area of ​​the touch screen.

[0039] Such a method makes it possible to control, via a voluntary action, the display of a set of statistical information on vehicle use, for example a history of speeds, the monthly or daily distance traveled, the distribution of vehicle use at different periods or seasons of a year, the distribution of vehicle use at different times of the day, the distribution of vehicle use in different types of environment, etc.

[0040] Fig. 1 schematically illustrates part of the passenger compartment of a vehicle 10, according to a particular and non-limiting embodiment of the present invention.

[0041] Vehicle 10 corresponds, for example, to a vehicle with an internal combustion engine, with electric motor(s), or even a hybrid vehicle with an internal combustion engine and one or more electric motors. Vehicle 10 thus corresponds, for example, to a land vehicle, for example a car, a truck, a bus.

[0042] The vehicle 10 advantageously incorporates a display system comprising a touchscreen 13 and a computer configured to control the display of content(s) of a graphic HMI on the touch screen 13. The computer corresponds for example to the computer of the infotainment system, called IVI computer (from the English "In-Vehicle Infotainment" or in French "Infodivertissement étoilé") of the vehicle 10.

[0043] The touch screen 13 corresponds for example to an LCD type screen (from the English "Liquid Crystal Display" or in French "Display à cristals liquide"), for example of type TFT (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").

[0044] The touchscreen 13 is configured to display content for the driver and passengers of the vehicle 10. The touchscreen 13 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 13. For example, the screen 13 is configured to interact with the IVI system and / or the odometer of the vehicle 10.

[0045] The screen 13 is for example arranged in the dashboard 11, in a space provided behind the steering wheel 14 according to the point of view of a driver of the vehicle 10 sitting in the driver's seat 15. Such a screen 13 is also called the instrument cluster or dashboard of the vehicle 10.

[0046] 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 sitting in the seat 15 sees the content displayed or projected onto the transparent blade when the driver is driving the vehicle 10. The display system further includes, for example, a display screen 12 arranged in a central space of the dashboard 11.

[0047] According to a particular embodiment, the vehicle 10 carries one or more embedded systems, each controlled by one or more computers, including an odometer. These computers, together with the IVI computer, form, for example, a multiplexed architecture for providing various services useful for the proper functioning of the vehicle and for assisting the driver and / or passengers in controlling the vehicle 10 by controlling the embedded system(s) in the vehicle 10. The computers communicate and exchange data with each other via one or more computer buses, for example, a CAN (Controller Area Network), CAN FD (Controller Area Network Flexible Data-Rate), FlexRay (according to ISO 17458), or LIN (Local In- interconnected Network » or in French « Local interconnected network» or Ethernet (according to the ISO / IEC 802-3 standard).

[0048] According to various embodiments, the vehicle 10 also carries one or more of the following systems: - a navigation and geolocation system, also called a GNSS (Geolocation and Navigation by Satellite System) system, for example a GPS (Global Positioning System) or Galileo type system, which is configured to provide the vehicle 10 with data representative of its geographical position at all times, for example in the form of GPS coordinates (latitude and longitude); and / or - a communication system comprising, for example, one or more communication antennas connected to a telematic control unit (TCU), itself connected to one or more computers of the vehicle's on-board system 10; such a configuration system is configured so that the vehicle 10 communicates with one or more servers in the cloud to obtain, for example, data on the environment traversed by the vehicle 10, such as meteorological data; and / or - an environmental data measurement system, such a system comprising a computer controlling a set of sensors, each configured to measure physical quantities such as meteorological data (temperature, rain, fog, snow, etc.), brightness (to detect whether it is day or night, for example), etc.; and / or - a clock to obtain the date and time at any given moment.

[0049] A control process for an on-board display system in the vehicle 10 is advantageously implemented by one or more processors of the display system, for example by one or more processors of one or more computers, for example the computer of the IVI system.

[0050] According to a particular embodiment, the process described below is implemented by a mobile communication device, such as a smartphone or tablet, connected in communication (for example wirelessly) to the vehicle 10 to obtain the data necessary for the implementation of the process (for example, data from the odometer(s)).

[0051] In a first operation of the process, initial representative data from one or more odometers are received from the vehicle's pedometer 10.

[0052] This initial data is, for example, received from the vehicle's pedometer control unit 10 via one or more data buses. This initial data is received, for example, automatically or upon request from the control unit responsible for the process.

[0053] The initial data, for example, represents a total odometer reading that records the distance traveled (in km) by vehicle 10 since it was first registered. The initial data providing the total mileage of vehicle 10 is, for example, received automatically each time vehicle 10 is started.

[0054] According to one variant, the first data are representative of one or more partial odometers (also called trip odometers), a partial or trip odometer indicating the distance travelled by the vehicle 10 since the last reset of this partial odometer by a user of the vehicle 10, for example the driver.

[0055] In a second operation of the process, the display of a first graphic content representing the odometer(s) represented by the first data is controlled in such a way that this first graphic content is displayed on the touch screen 13 in a first area of ​​the touch screen 13, following the reception of the first data.

[0056] Fig. 2 illustrates a result of the display control of the first graphic content 21 on the touch screen 13, according to a particular and non-limiting embodiment.

[0057] According to the example in [Fig. 2], the first graphic content 21 is displayed in a first area corresponding to a lower portion of the touchscreen 13, in the middle of the lower portion of the touchscreen 13 from the viewpoint of a person looking at the screen 13 from a front seat of the vehicle 10, for example. Of course, the first area can correspond to any area of ​​the screen, for example, a lower right or left portion, or even the upper portion of the touchscreen 13.

[0058] The first graphic content 21 displayed includes, for example, the total mileage odometer of the vehicle 10 corresponding to a number of kilometers travelled by the vehicle 10 (this number being equal to 17225 kms according to the example in [Fig.1]).

[0059] According to other embodiments, the first graphic content 21 further includes one or more of the following information or data: - one or more partial (or daily) meters; and / or - one or more pieces of information relating to a vehicle 10 stop-start system (also called an STT system (from the English "Stop and Start" or in French "arrêt et départ") such as the duration of the vehicle 10 engine stop controlled by the STT system on the current route of the vehicle 10; and / or - the outside temperature; and / or - the current time.

[0060] A display control for graphic content, such as the first graphic content 21, or for any graphic object (text, pictogram, icon, etc.) includes a rendering of the graphic content or graphic object, such rendering corresponding to a set of operations performed by one or more processors on the pixels of one or more images of the graphic content to be displayed on the screen 13. For example, rendering consists of associating to a set of pixels of an image pixel data (for example color data expressed in an RGB type space (from the English "Red, Green, Blue" or in French "rouge, vert, bleu")) associated with each graphic object.

[0061] The display control of the first graphic content 21 thus includes the transmission of control signals to the touch screen 13 to modify the values ​​associated with the pixels of the touch screen 13 at the location intended to display the first graphic content 21, for example the values ​​of the pixels used for displaying the values ​​taken by the odometer(s) included in the first graphic content 21.

[0062] Other graphic content (not illustrated in [Fig. 1]) is displayed simultaneously with the first graphic content, for example, graphic content representing a rev counter, graphic content representing a speedometer, graphic content associated with an AD AS system (from the English "Advanced Driver-Assistance System" or in French "Système d'aide à la conduite avancé") such as adaptive cruise control, a lane departure warning system or a lane keeping system.

[0063] In a third operation, second data representing a first touch 210 on the first graphic content 21 are received, following a touch 210 by a user (for example the driver of the vehicle 10) on the first graphic content 21.

[0064] A touch press on the first graphic content 21 sends information to the IVI computer so that the latter implements one or more functions associated with the command corresponding to the touch press.

[0065] The second data representing the touch press are received for example via one or more data buses linking the touch interface of the screen (or a computer controlling such a touch interface where applicable) and the IVI computer.

[0066] The first touch 210 corresponds for example to a so-called short or brief touch, that is to say a touch whose duration of pressing on the first graphic content 21 is less than a threshold duration (for example equal to 500 or 1000 ms).

[0067] In a fourth operation of the process, the IVI control unit controls the display of a second graphic content comprising one or more initial statistical data points on vehicle use 10 over a first predetermined time interval. The display control of the graphic content is triggered, for example, by the reception of the second data point. The second graphic content is displayed in a second area of ​​the touchscreen 13, different from the first area in which it is displayed the first graphic content 21.

[0068] The first time interval corresponds, for example, to a system parameter whose value can be adjusted by a user via a dedicated HMI (Human-Machine Interface). The duration of the first time interval is, for example, equal to 6, 12, or 24 months, meaning that the first time interval corresponds to the 6, 12, or 24 months elapsed before the moment corresponding to the first touch press 210. According to another example, the duration corresponds to the time elapsed since the vehicle 10 was first put into service.

[0069] The fourth operation includes, for example, the transmission of a request by the IVI computer to one or more computers controlling one or more systems to obtain the first statistical information enabling the construction or generation of the second graphic content.

[0070] Fig. 3 illustrates the result of displaying a second graphic content 30 following a particular embodiment example.

[0071] According to a particular example, the second graphic content 30 is displayed in a window occupying part of the display area of ​​the screen 13 and corresponding to the second zone, this window corresponding, for example, to a pop-up window, also called an intrusive or pop-up window. This window is, for example, displayed in a second zone located above the first zone, this second graphic content 30 replacing (or overlapping) the graphic content previously displayed on the touch screen 13, that is to say, before the first touch 210.

[0072] The second graphic content 30 illustrated in [Fig.3] comprises: - a first diagram 301 representing a history of the vehicle 10's speeds over the first determined time interval, that is to say, a representative profile of the vehicle 10's speeds as a function of time; and - a second diagram 302 representing a histogram of monthly usage time (for example expressed in hours) of vehicle 10 for each month included in the first determined time interval.

[0073] According to one embodiment, other statistical information is displayed with the first diagram 301 and diagram 302. For example, the average speed of the vehicle 10 over the first time interval is displayed or represented on the first diagram 301. A text area is further displayed, for example, with the second diagram 302, for example below the histogram, to indicate the percentage of time during which the vehicle 10 was stopped, parked or unused (engine off) over the first time interval.

[0074] According to other embodiments, the second graphic content 30 includes other statistical information, in addition to that displayed via the first diagram 301 and / or the second diagram 302, or instead of the first and second diagrams.

[0075] For example, the first statistical information on vehicle use corresponds to one or more of the following information, according to all possible combinations: - information representing a vehicle speed profile over time within a time interval corresponding to the first determined time interval; and / or - information representing the average speed of the vehicle over the time interval; and / or - information representing the duration of vehicle use over the time interval and / or information representing the duration of vehicle non-use over the time interval; and / or - information representing the distance travelled by vehicle 10 over the time interval; and / or - information representative of a duration of use of the vehicle 10 for each temporal subdivision (corresponding to a day, a month, a semester, a year) of a set of temporal subdivisions forming the time interval; - information representing a distance travelled by vehicle 10 during each time subdivision of the set of time subdivisions; - information representative of a distribution of vehicle use according to at least one vehicle use criterion, a use criterion corresponding for example to the season (e.g. summer and winter), to the time of day (e.g. day and night), to the type of environment traversed by the vehicle 10 (e.g. road, motorway, city, countryside, etc.).

[0076] The first statistical information represented in the second graphic content 30 corresponds, for example, to parameters adjustable via an ad hoc GUI, as well as the type of representation used.

[0077] In an additional operation of the process, according to a particular embodiment of the process, third data representing a touch scan 310 on a part of the second graphic content 30 are received following the execution of a touch scan at the display location of the second graphic content 30 on the screen 13 by a user, for example the driver, a passenger or a manager of the vehicle 10.

[0078] A touch swipe corresponds to a continuous and prolonged touch contact of one (or more) finger on a part of the screen 13, the continuous and prolonged touch contact forming a trace of a segment (from 1 to several centimeters, for example), the segment being, for example, horizontal (as represented by arrow 310 in [Fig. 3]), or even vertical or oblique.

[0079] Following the reception of the third data, the display of a third graphic content is controlled in such a way that this third graphic content is displayed in the second zone, replacing the second graphic content 30.

[0080] The third graphic content includes one or more second statistical data points regarding the use of vehicle 10 over a second specified time interval. The second statistical data point(s) regarding the use of vehicle 10 are different from the first statistical data point(s) regarding the use of vehicle 10 represented in the second graphic content 30.

[0081] The second time interval is, for example, identical to the first time interval. According to another variant, the second time interval is different from the first time interval, for example, of a different duration. The second time interval corresponds, for example, to an adjustable parameter of the system.

[0082] The second statistical information on the use of vehicle 10 corresponds to one or more of the following information, according to all possible combinations: - information representing a vehicle speed profile over time, corresponding to the second determined time interval; and / or - information representing the average speed of the vehicle over the time interval; and / or - information representing the duration of vehicle use over the time interval and / or information representing the duration of vehicle non-use over the time interval; and / or - information representing the distance travelled by vehicle 10 over the time interval; and / or - information representative of a duration of use of the vehicle 10 for each temporal subdivision (corresponding to a day, a month, a semester, a year) of a set of temporal subdivisions forming the time interval; - information representing a distance travelled by vehicle 10 during each time subdivision of the set of time subdivisions; - information representative of a distribution of vehicle use according to at least one vehicle use criterion, a use criterion corresponding for example to the season (e.g. summer and winter), to the time of day (e.g. day and night), to the type of environment traversed by the vehicle 10 (e.g. road, motorway, city, countryside, etc.).

[0083] Fig. 4 illustrates the result of displaying a third graphic content 40 following a particular embodiment example.

[0084] According to the particular example of [Fig.4], the third graphic content 40 comprises: - a third diagram 401 representing a day / night usage distribution of vehicle 10, that is to say a graphic object representing the percentage of use of the vehicle when it is daytime and the percentage of use of vehicle 10 when it is nighttime over a period of time corresponding to the second time interval; - a fourth diagram 402 representing a summer / winter usage distribution of vehicle 10, i.e. a graphic object representing the percentage of vehicle use in summer (including the spring and summer months) and the percentage of vehicle use 10 in winter (including the autumn and winter months) over the time period corresponding to the second time interval; and - a fifth diagram 403 representing a vehicle use distribution by type of environment, for example the vehicle use distribution for each environment in a list of determined environments (e.g. road, motorway or road, motorway, city, countryside), i.e. a graphic object representing the percentage of vehicle use 10 for each environment.

[0085] Each graphic object corresponds for example to a pie chart type object (also called a pie chart or pie plate), a column chart type object, a bar chart type object, or any graphic object known to represent statistical information as a percentage.

[0086] Different colours are for example associated with each sector representing a particular use, a legend of the colours with their meaning being for example displayed under each diagram 401, 402, 403.

[0087] The second statistical information represented in the third graphic content 40 corresponds, for example, to parameters adjustable via an ad hoc GUI, as well as the type of representation used.

[0088] The second statistical information (and / or the first statistical information) is determined, for example, from data obtained from one or more on-board systems of the vehicle 10, such as the navigation system (for example, to determine what type of environment the vehicle 10 is operating in), the light detection system (for example, to determine day and night), the clock (to determine the season), the communication system or the environmental monitoring system to obtain meteorological data, etc.

[0089] According to a particular embodiment, the reception of fourth data representing a second touch press on the first graphic content 21 triggers the end-of-display control of the current graphic content then displayed in the second zone during the second touch press and corresponding to the second content graph 30 or the third graphic content 40.

[0090] Thus, when the second touch press on the first graphic content 21 is performed while the second graphic content 30 is displayed on the screen 13, then the computer in charge of the process controls the end of the display of the second graphic content 30.

[0091] When the second touch press 410 on the first graphic content 21 is performed while the third graphic content 40 is displayed on the screen 13, then the computer in charge of the process controls the end of the display of the third graphic content 40.

[0092] The graphic content displayed on screen 13 in place of the second graphic content 30 or the third graphic content 40 then corresponds to the graphic content displayed before the moment corresponding to the first touch press 210.

[0093] The second touch press 410 corresponds for example to a so-called short or brief touch press, that is to say a touch press of duration less than the threshold duration (for example equal to 500 or 1000 ms) described previously.
