Description

Title of the invention: Method and device for controlling a display system for displaying interaction information with interfaces of a driver's station Technical field

[0001] The present invention relates to methods and devices for displaying interaction information with interfaces of a driver's station. In particular, the present invention relates in particular to methods and devices for controlling a display system associated with a human-machine interface on board a vehicle, in particular but not exclusively a motor vehicle. Technological background

[0002] Distractions while driving are factors that divert the driver's attention from the road and thus compromise safety. They can be classified into three main categories: • visual distractions: this involves taking your eyes off the road. For example, looking at a mobile phone, reading advertising signs, interacting with an on-board vehicle system; • manual distractions: these are activities that involve moving the hands from the steering wheel to perform other tasks, for example, operating the radio or air conditioning, writing a destination name into a guidance system; and • cognitive distractions: these distractions occur when the driver's mind is preoccupied with something other than driving, for example, thinking about personal problems, being stressed or tired, or even being focused on a task such as interacting with a human-machine interface, called HMI.

[0003] Distracted driving can lead to serious consequences, significantly increasing the risk of accidents. According to statistics, accidents caused by distractions are becoming increasingly common. The main measures to avoid these distractions are: • responsible use of electronic devices by avoiding using a mobile phone while driving or using hands-free devices, or even parking the vehicle to use this type of device; or • advance planning by completing certain tasks before setting off or during a break along a journey.

[0004] Preventing distracted driving is essential to ensure the safety of road users. It is therefore crucial to concentrate as much as possible on driving to avoid potentially serious accidents. Summary of the present invention

[0005] An object of the present invention is to solve at least one of the problems of the technological background described above.

[0006] Another object of the present invention is to better facilitate the interaction between a driver and a human-machine interface, called HMI, by significantly reducing the time of this interaction, in particular by minimizing the time when a driver of a vehicle takes his eyes off the road.

[0007] According to a first aspect, the present invention relates to a method for controlling an on-board display system in a vehicle, the display system comprising a display device positioned in a first zone of a passenger compartment of the vehicle, the method comprising the following steps: - reception of first data representative of the presence of a finger of a user positioned at a determined distance from a first touch interface associated with a human-machine interface of an on-board system of the vehicle, the first touch interface being positioned in a second zone of a passenger compartment of the vehicle, the second zone being distinct from the first zone; - determining a first set of touch interfaces comprising the first touch interface and determining a set of at least one first graphic object associated with the first set of touch interfaces; - display control of a first graphic content comprising the set of at least one first graphic object and a second graphic object on the display device, a position of the second graphic object relative to said second set of at least one first graphic object being representative of a position of the finger relative to the first touch interface.

[0008] Such a method allows a user, for example the driver of the vehicle, to view a set of touch interfaces that he is about to use by displaying graphic content representing this set of touch interfaces in his field of vision when he is driving. It is then not necessary for the driver to turn or lower his head to look directly at the set of touch interfaces. Thus, handling is easier and the interaction time with the HMI is reduced. The driver thus has more time to concentrate on his driving.

[0009] According to a variant of the method, the distance is between 0.5 and 5 mm.

[0010] According to another variant of the method, the first touch interface is a button or part of a touch screen.

[0011] According to another variant of the method, the first set of touch interfaces comprises touch interfaces adjacent to the first touch interface.

[0012] According to a further variant of the method, the display device is positioned in a field of vision around a main axis associated with a driving position of the vehicle.

[0013] According to another variant, the method further comprises a step of displaying a third graphic object representative of an activation of a function associated with a touch interface of the first set of touch interfaces.

[0014] According to another variant, the method further comprises a rendering of audio content, the audio content being determined as a function of the first touch interface.

[0015] According to a second aspect, the present invention relates to a device for controlling an on-board display system in a vehicle, the device comprising a memory associated with a processor configured for implementing the steps of the method according to the first aspect of the present invention.

[0016] 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.

[0017] According to a fourth aspect, the present invention relates to a computer program which comprises instructions adapted for executing the steps of the method according to the first aspect of the present invention, in particular when the computer program is executed by at least one processor.

[0018] Such a computer program may use any programming language, and be in the form of source code, object code, or intermediate code between source code and object code, such as in a partially compiled form, or in any other desirable form.

[0019] 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 method according to the first aspect of the present invention.

[0020] On the one hand, the recording medium may be any entity or device capable of storing the program. For example, the medium may comprise a storage means, such as a ROM memory, a CD-ROM or a microelectronic circuit type ROM memory, or a magnetic recording means or a hard disk.

[0021] Furthermore, this recording medium may also be a transmissible medium such as an electrical or optical signal, such a signal being able to be conveyed via an electrical or optical cable, by conventional or hertzian radio or by self-directed laser beam or by other means. The computer program according to the present invention may in particular be downloaded from an Internet-type network.

[0022] Alternatively, the recording medium may be an integrated circuit in which the computer program is incorporated, the integrated circuit being adapted to execute or for use in carrying out the process in question. Brief description of the figures

[0031] A method and a device for controlling an on-board display system in a vehicle will now be described in the following with joint reference to FIGS. 1 to 7. The same elements are identified with the same reference signs throughout the description which follows.

[0032] The terms "first(s)", "second(s)" (or "first(s)", "second(s)"), etc. are used in this document by arbitrary convention to enable different elements (such as operations, means, etc.) implemented in the embodiments described below to be identified and distinguished. Such elements may be distinct or correspond to a single element, depending on the embodiment.

[0033] According to a particular and non-limiting example of embodiment of the present invention, the control of a display system on board a vehicle is for example implemented implemented by one or more vehicle computers, for example via one or more processors.

[0034] For this purpose, first data representative of the presence of a finger of a user, for example a driver of the vehicle, positioned at a determined distance from a touch interface are received, the first touch interface being positioned in a second zone distinct from the first zone.

[0035] A first set of touch interfaces comprising the first touch interface is then determined as well as a set of at least one first graphical object associated with the first set of touch interfaces.

[0036] The display of a first graphic content comprising the set of at least a first graphic object and a second graphic object is controlled on the display device, a position of the second graphic object being representative of a position of the finger relative to the first touch interface.

[0037] The user is then able to perceive the position of his finger relative to the set of touch interfaces and thus interacts precisely with the desired touch interface, the positioning of his finger being adjusted by looking at the display device rather than the touch interface in question, the touch interface in question being able to be located outside his field of vision when driving. The user thus keeps his gaze oriented towards the road and the time required for interaction with an HMI is reduced. Driving is therefore safer.

[0038] [Fig. 1] schematically illustrates a passenger compartment of a vehicle 10, according to a particular and non-limiting exemplary embodiment of the present invention.

[0039] The vehicle 10 corresponds for example to a vehicle with a thermal engine, with electric motor(s) or even a hybrid vehicle with a thermal engine and one or more electric motors. The vehicle 10 thus corresponds for example to a land vehicle, for example an automobile, a truck, a bus.

[0040] The vehicle 10 advantageously incorporates at least one on-board system controlled using a human-machine interface, called HMI. The on-board system is for example a driving assistance system, air conditioning in the passenger compartment of the vehicle 10 and / or an on-board infotainment system, called IVI system (from the English “In-Vehicle Infotainment” or in French “Infodivertissement monté”).

[0041] According to a particular embodiment, each on-board system is controlled by one or more computers. These computers form, for example, a multiplexed architecture for the realization of different services useful for the proper functioning of the vehicle and for assisting the driver and / or the passengers of the vehicle in the control of the vehicle 10 via the control of the system(s) on-board in the vehicle 10. The computers communicate and exchange data between them via one or more computer buses, for example a communication bus communication of the data bus type CAN (from the English "Controller Area Network" or in French "Réseau de contrôles"), CAN FD (from the English "Controller Area Network Flexible Data-Rate" or in French "Réseau de contrôles 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).

[0042] The HMI further comprises touch interfaces 12 making it possible to control the various on-board systems of the vehicle 10. The touch interfaces 12 belong to a set of touch interfaces comprising: - a mechanical button, for example a push button activated by mechanical pressure from a user's finger 100, - a touch button also called a contactless button, for example activated when a user's finger 100 touches the touch button on a surface for a set period of time, - part of a 16 touch screen.

[0043] The touch screen 16 is for example associated with a touch interface and corresponds for example to a screen of the LCD type (from the English “Liquid Crystal Display” or in French “Display à cristals liquide”), for example of the TFT type (from the English “Thin-Film Transistor” or in French “Transistor en film mince”), or OLED type (from the English “Organic Light-Emitting Diode” or in French “Diode électroluminescente biologique”).

[0044] The touch screen 16 is configured to display content intended for the driver and passengers of the vehicle 10. The touch screen 16 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 1THM displayed on the touch screen 16. For example, the touch screen 16 is configured to interact with the IVI system and / or a navigation system of the vehicle 10.

[0045] The position of a finger 100 of a user relative to a touch interface 12 is detected when this finger 100 is positioned close to a touch interface 12. Proximity refers to the presence of the finger in a near field, for example close to an external surface of the touch interface 12.

[0046] According to a first particular embodiment, this distance is strictly positive, that is to say strictly greater than 0 mm, for example the distance is between 0.5 and 5 mm. Such a distance is for example associated with a touch button or with a part of a touch screen 16, in fact when the finger 100 is at a distance less than the limits previously defined the finger 100 is considered to be in contact with the touch interface 12 while the finger is considered to be approaching the touch interface 12 when it is present in the determined field. In fact, the response of the HMI is not identical depending on whether the finger 100 is approaching or is in contact with the touch interface 12.

[0047] According to a second particular embodiment, for example associated with a mechanical button, this distance is greater than or equal to 0 mm. Indeed, the HMI considers the activation of the mechanical button not when the finger 100 is in contact with an external surface of the touch interface 100 but when the finger 100 exerts a force greater than a threshold, for example 2N or 10N. Thus, if the finger 100 is present in a field less than a threshold distance, for example a few millimeters or a few centimeters, then this finger 100 is considered to be approaching this touch interface 12.

[0048] A touch interface 12 thus detects a presence and / or a movement of the finger 100 and / or a pressure or a force exerted by the finger 100 on an external surface of the touch interface 12. This detection is for example carried out by a capacitive type sensor or by an optical type sensor, for example associated with each touch interface 12. The sensor associated with a touch interface 12 emits for example electrical signals to a computer of the HMI according to the presence and the position of a finger 100 in its proximity.

[0049] According to an alternative embodiment, a camera placed in the passenger compartment detects the position of the user's finger 100 and compares this position to those of different touch interfaces 12 embedded in the passenger compartment of the vehicle 10. The camera is for example placed in a ceiling light or in the central rearview mirror, making it possible to cover all of the touch interfaces 12 in its field of vision. Thus, a single sensor is sufficient to detect a finger 100 near a touch interface 12 among a plurality of touch interfaces 12.

[0050] Each touch interface 12 is positioned in a second zone 11b, 11c, 11d, 11e of the passenger compartment of the vehicle 10, the second zone being distinct from the first zone 11a. In the example illustrated in [Fig.l], each of these second zones 11b, 11c, 11d, 11e comprises a set of touch interfaces 12, that is to say at least one touch interface 12. The invention is however not limited to the number of touch interfaces 12 per second zone or per set of touch interfaces, thus a second zone comprises at least one touch interface 12, for example one, two, or more touch interfaces 12.

[0051] Thus, a touch interface 12 is for example placed: - in a second zone 11b associated with a dashboard comprising, for example, six touch interfaces 12; - in a second zone 1 associated with a central tunnel, for example positioned between a driver's seat 14a and a passenger seat 14b, comprising, for example, four touch interfaces 12; - in a second zone 1 Id associated with a steering wheel or a branch of a steering wheel, comprising, for example, five touch interfaces 12; or - in a second zone associated with a central console comprising, for example, a touch screen 16, comprising, for example, nine touch interfaces 12.

[0052] The passenger compartment of the vehicle 10 also comprises a display system comprising a display device 13 positioned in a first zone 11a of the passenger compartment of the vehicle 10. The display system is for example connected to the computer, for example the HMI, and makes it possible to display graphic content so as to facilitate any interaction of a user, for example the driver of the vehicle 10, with one or more on-board systems of the vehicle 10.

[0053] According to a particular embodiment, the display system further comprises a display device 13 corresponding for example to a transparent or semi-transparent blade, for example arranged on top of the dashboard in front of the windshield 15 of the vehicle 10. The transparent blade is for example arranged behind the steering wheel, according to the point of view of a driver installed in the driver's seat 14a, in such a way that the driver sees the content displayed or projected on the transparent blade, that is to say on the display device 13, when the driver is driving the vehicle 10. The transparent blade thus corresponds to an element of a so-called head-up display device or system. Such a display system comprises for example one or more projectors integrated for example in the dashboard.Such a system for projecting images or graphic content corresponds, for example, to a so-called augmented reality system, called AR (from the English "Augmented Reality"), for example a Head-Up Display system, called VTH or HUD (from the English "Head Up Display" or in French "Display Head High"), which allows the incrustation of virtual objects in the driver's field of vision by projecting the images onto the display device 13. The projection of the images of the graphic object is, for example, controlled by one or more computers of the on-board system of the vehicle 10, for example by the IVI computer. The connection between the computer and the head-up display device corresponds, for example, to a connection of the LVDS type (from the English "Low Voltage Differential Signaling" or in French "Low Voltage Differential Transmission").According to this exemplary embodiment, the display device 13 is positioned in a field of vision around a main axis associated with a driving position of the vehicle 10, that is to say in the main field of vision of the driver of the vehicle 10. Thus, the driver of the vehicle 10 sees the graphic content displayed on the display device 13 without taking his eyes off the road.

[0054] A process for controlling an on-board display system in the vehicle 10 is advantageously implemented by one or more processors of the on-board display system in the vehicle 10, for example by a computer of the IVI system.

[0055] [Fig. 2] illustrates a first example of interaction between a user and a touch interface. The first touch interface 12 is located in the second zone 11b associated with the dashboard which comprises six touch interfaces 12. The user's finger 100 is positioned close to the third touch interface 12 starting from the left, the six touch interfaces 12 being horizontally aligned and distributed regularly along the horizontal direction. The first touch interface 12 is for example a touch button or touch key associated with a function of an air conditioning system in the passenger compartment of the vehicle 10.

[0056] In a first operation, first data representative of a presence of the finger 100 of a user positioned at a determined distance from a first touch interface 12 associated with the HMI of an on-board system of the vehicle 10 are received. The first touch interface 12 is notably positioned in a second zone 11b of the passenger compartment of the vehicle 10 distinct from the first zone 11a where the display device 13 is positioned. Figures 3 to 5 illustrate other examples of interaction between a user and a touch interface, a finger 100 of a user being placed on different touch interfaces 12 according to each illustrated example.

[0057] In a second operation, a first set of touch interfaces 120 comprising the first touch interface 12 is determined. This first set 120 comprises for example a group of at least one touch interface 12 comprising the first touch interface 12. The first set 120 corresponds for example to a keyboard comprising several touch interfaces 12 adjacent or located at a distance less than a threshold distance from a touch interface 12 of this first group 120. It is possible that the finger 100 detected near the first touch interface 12 will interact with the first touch interface 12, but it is also possible that the finger 100 will interact with a second touch interface 12 of the same first set 120.Indeed, the user not looking at his finger 100 or the touch interfaces 12 directly, for example because he is driving, the finger 100 is then approximately in front of the touch interface 12 targeted by the user.

[0058] Thus, it is possible that the user wishes to interact with another touch interface 12 of the first set 120 different from the first touch interface 12. According to a particular exemplary embodiment, the first set of touch interfaces 120 then comprises touch interfaces 12 adjacent to said first touch interface 12, for example located above, below, to the left or to the right of the first touch interface 12.

[0059] According to a particular exemplary embodiment, each touch interface 12 is associated with a set of touch interfaces, the first set 120 is for example determined from a database or a correspondence table as a function of the first touch interface 12

[0060] In a third operation, a second set of at least one graphical object 210 associated with the first set of touch interfaces 120 is determined. Each graphic object 21 of the second set 210 corresponds to a touch interface 12 of the first set 120. Each graphic object 21 is for example rectangular in shape and comprises an icon or a text message positioned in its center, the icon or the text message making it possible to identify a function associated with a touch interface 12. It should be noted that the icon or the text message corresponds, for example, to a screen print applied to the touch interface 12. Thus, the number of graphic objects 21 of the second set 210 is, for example, equal to the number of touch interfaces 12 included in the first set 120. The second set 210 reproduces a virtual image of the first physical set 120.

[0061] In a fourth operation, a display of a first graphic content is controlled on the display device 13. The first graphic content then comprises the second set of at least a first graphic object 210 and a second graphic object 200, a position of the second graphic object relative to the second set 210 being representative of a position of the finger 100 relative to the first touch interface 12. The second graphic object 200 is for example of circular or oval shape, superimposed in transparency above the second set 210.

[0062] Thus, by looking at the display device 13, a user is able to perceive the relative position of his finger with respect to the first touch interface 12 or even with respect to the first set of touch interfaces 120.

[0063] According to a particular exemplary embodiment, a third graphic object 22 representative of an activation of a function associated with a touch interface of the first set of touch interfaces is displayed on the display device 13. This third graphic object is for example rectangular in shape and positioned in the first graphic object 21 associated with a function. A first fill color of the third graphic object 22 indicates for example an activation of the function of an on-board system associated with the first graphic object 21 and therefore with the first touch interface 12 while a second color indicates for example a non-activation or deactivation of this same function. It should be noted that other colors or other shapes can also be used, for example to easily identify a setting level associated with a function of an on-board system of the vehicle 10.Likewise, the appearance of the third graphic object 22 may correspond to the switching on or off of an indicator light associated with a touch interface 12.

[0064] According to a particular exemplary embodiment, in a fifth operation an audio content is rendered, for example via speakers embedded in the passenger compartment of the vehicle 10. The audio content is for example determined as a function of the first touch interface 12, then allowing the user to identify the touch interface 12 located near his finger 100 without having to look at the first touch interface 12 or the display device 13, the user can thus continue to look at the road if he is driving while interacting with the HMI.

[0065] [Fig. 3] illustrates an interaction between a user and a touch interface located in the second zone 11e associated with the central tunnel, for example positioned between a driver's seat 14a and a passenger seat 14b and comprising four touch interfaces 12.

[0066] According to the example of [Fig. 3], the user's finger 100 is positioned on the third touch interface 12 starting from the left, the four touch interfaces 12 being aligned horizontally. The first touch interface 12 is for example a mechanical button or mechanical key associated with a function of a driving assistance system for the vehicle 10 in off-road conditions.

[0067] [Fig.4] illustrates an interaction between a user and a touch interface located in the second zone 1 Id associated with a steering wheel or a branch of a steering wheel, comprising five touch interfaces 12.

[0068] According to the example of [Fig.4], the user's finger 100 is positioned on the first touch interface 12 starting from the top left, the five touch interfaces 12 being aligned horizontally and vertically along a cross. The first touch interface 12 is for example a touch button or touch key associated with a function of a cruise control system of the vehicle 10.

[0069] [Fig. 5] illustrates an interaction between a user and a touch interface located in the second zone associated with a central console comprising, for example, a touch screen 16, comprising, for example, nine touch interfaces 12.

[0070] According to the example of [Fig.5], the user's finger 100 is positioned on the touch interface 12 in the center of a first set 120 comprising nine touch interfaces 12. The nine touch interfaces 12 form a keyboard and are aligned horizontally and vertically. The first touch interface 12 is for example an area of ​​a touch screen 16 and is associated with a function of an air conditioning system in the passenger compartment of the vehicle 10.

[0071] [Fig. 6] schematically illustrates a device 6 configured for controlling a display system on board a vehicle, for example the vehicle 10, according to a particular and non-limiting exemplary embodiment of the present invention. The device 6 corresponds for example to a device on board the vehicle 10, for example a computer.

[0072] The device 6 is for example configured for implementing the operations described with regard to figures 1 to 5 and / or the steps of the method described with regard to [Fig.7]. Examples of such a device 6 include, but are not limited to, a on-board electronic equipment such as a vehicle's on-board computer, an electronic calculator such as an ECU ("Electronic Control Unit"), a smartphone, a tablet, a laptop. The elements of the device 6, individually or in combination, can be integrated into a single integrated circuit, into several integrated circuits, and / or into discrete components. The device 6 can be produced in the form of electronic circuits or software (or computer) modules or even a combination of electronic circuits and software modules.

[0073] The device 6 comprises one (or more) processor(s) 60 configured to execute instructions for carrying out the steps of the method and / or for executing the instructions of the software(s) embedded in the device 6. The processor 60 may include integrated memory, an input / output interface, and various circuits known to those skilled in the art. The device 6 further comprises at least one memory 61 corresponding for example to a volatile and / or non-volatile memory and / or comprises a memory storage device which may comprise volatile and / or non-volatile memory, such as EEPROM, ROM, PROM, RAM, DRAM, SRAM, flash, magnetic or optical disk.

[0074] The computer code of the embedded software(s) comprising the instructions to be loaded and executed by the processor is for example stored in the memory 61.

[0075] According to various particular and non-limiting embodiments, the device 6 is coupled in communication with other similar devices or systems and / or with communication devices, for example a TCU (from the English “Telematic Control Unit” or in French “Telematic Control Unit”), for example via a communication bus or through dedicated input / output ports.

[0076] According to a particular and non-limiting exemplary embodiment, the device 6 comprises a block 62 of interface elements for communicating with external devices. The interface elements of the block 62 comprise one or more of the following interfaces: - RF radio frequency interface, for example Wi-Fi® type (according to IEEE 802.11), for example in the 2.4 or 5 GHz frequency bands, or Bluetooth® type (according to IEEE 802.15.1), in the 2.4 GHz frequency band, or Sigfox type using UBN (Ultra Narrow Band) radio technology, or LoRa in the 868 MHz frequency band, LTE (Long-Term Evolution), LTE-Advanced; - USB interface (from the English “Universal Serial Bus” or “Universal Serial Bus” in French); - HDMI interface (from the English “High Definition Multimedia Interface” or “High Definition Multimedia Interface” in French); - LIN interface (from the English “Local Interconnect Network”).

[0077] According to another particular and non-limiting exemplary embodiment, the device 6 comprises a communication interface 63 which makes it possible to establish communication with other devices (such as other computers of the on-board system) via a communication channel 630. The communication interface 63 corresponds for example to a transmitter configured to transmit and receive information and / or data via the communication channel 630. The communication interface 63 corresponds for example to a wired network of the CAN (Controller Area Network) type, CAN FD (Controller Area Network Flexible Data-Rate), FlexRay (standardized by the ISO 17458 standard) or Ethernet (standardized by the ISO / IEC 802-3 standard).

[0078] According to a particular and non-limiting exemplary embodiment, the device 6 can provide output signals to one or more external devices, such as a display screen 640, touch-sensitive or not, one or more speakers 650 and / or other peripherals 660 (projection system) via output interfaces 64, 65 and 66 respectively. According to a variant, one or other of the external devices is integrated into the device 6.

[0079] [Fig. 7] illustrates a flowchart of the different steps of a method for controlling an on-board display system in a vehicle, for example the vehicle 10, according to a particular and non-limiting exemplary embodiment of the present invention. The method is for example implemented by a device on board the vehicle 10 or by the device 6 of [Fig. 6]. The on-board display system in the vehicle 10 comprises a display device 13 positioned in a first zone 11a of the passenger compartment of the vehicle 10.

[0080] In a first step 71, first data representative of a presence of a finger 100 of a user positioned at a determined distance from a first touch interface 12 are received.
