Description

Title of the invention: Communication device for vehicle interior and associated vehicle

[0001] The present invention relates to a communication device for a vehicle passenger compartment.

[0002] The present invention also relates to a vehicle comprising such a communication device.

[0003] Vehicle interiors are often noisy places, whether due to the noise of the engine or other vehicle equipment, noise from outside the vehicle or noise made by passengers. Communication between the different passengers of the vehicle is therefore not always easy.

[0004] This is particularly true between the driver and another passenger, especially if the latter is sitting in the rear of the vehicle. Indeed, the driver will not be able to turn around to communicate easily with the passenger in the rear.

[0005] This can create awkward, even stressful, situations for passengers. This is particularly the case for a child sitting in the back of the vehicle. They will therefore have difficulty interacting with the person driving the vehicle, who may be their parent, for example, which can be a source of concern.

[0006] Conversely, a passenger wishing to isolate himself and remain calm will not always be able to easily inform the other passengers without appearing discourteous. In the context of carpooling, a passenger or the driver may wish to temporarily refrain from talking, for example when the driver is performing a complex maneuver or when the passenger wishes to sleep.

[0007] An aim of the invention is then to propose means of communication within a vehicle interior which are more pleasant for passengers and the driver, while being simple and inexpensive to set up.

[0008] To this end, the invention relates to a communication device for a vehicle passenger compartment, the vehicle comprising a plurality of interior trim elements for the passenger compartment and a plurality of seats intended to accommodate passengers, the seats being distributed into a front row and at least one rear row, the communication device comprising:

[0009] - at least one actuation module configured to emit an instruction actuation, each actuation module being intended to be actuated by a first passenger of the vehicle, and

[0010] - at least one signaling module comprising a light source, each signaling module being configured to switch according to the setpoint actuation between a rest state, in which the light source is off, and at least one communication state, in which the light source emits a light signal suitable for being seen by at least a second passenger of the vehicle, different from the first passenger,

[0011] in which the or each light source comprises a plurality of light-emitting diodes arranged in the form of an LED assembly and intended to be arranged on at least one trim element of the passenger compartment and / or at least one seat of the vehicle.

[0012] The communication device thus allows passengers to communicate with each other thanks to the light source, without making any more noise. The light source is easily installed in the vehicle interior and allows a large number of different animations to be provided, allowing peaceful communication within the vehicle.

[0013] According to other advantageous aspects of the invention, the communication device comprises one or more of the following characteristics, taken individually or in all technically possible combinations:

[0014] - the light source comprises an LED strip and / or an LED matrix;

[0015] - each actuation instruction is associated with a given communication state, each communication state corresponding to distinct optical properties of the light source;

[0016] - the communication device further comprises an isolation module specific to prevent at least one signaling module from switching from the idle state to the communication state.

[0017] The invention also relates to a vehicle comprising a passenger compartment comprising a plurality of interior trim elements, the vehicle comprising a plurality of seats intended to accommodate passengers, the seats being distributed into a front row and at least one rear row, the vehicle further comprising a communication device of the aforementioned type.

[0018] According to other advantageous aspects of the invention, the vehicle comprises one or more of the following characteristics, taken individually or in all technically possible combinations:

[0019] - at least one of the light sources comprises an LED strip extending at least partly in a longitudinal direction of the vehicle from the front row to the rear row;

[0020] - the LED strip is arranged on a door panel, on a ceiling light or on a vehicle floor;

[0021] - each seat is associated with a given actuation module;

[0022] - the vehicle comprises at least one noise reduction system associated with a zone of the passenger compartment, called the quiet zone, a luminous warning device being arranged in or near said quiet zone and being capable of switching to a warning state when the noise reduction system is active;

[0023] - said light warning device comprises an LED strip arranged on the floor so as to delimit the quiet zone by surrounding it.

[0024] The invention will appear more clearly on reading the description which follows, given solely by way of non-limiting example, and made with reference to the drawings in which:

[0025] [Fig.l] [Fig.l] is a schematic top view of a vehicle interior according to the invention;

[0026] [Fig.2] [Fig.2] is a schematic perspective view illustrating the passenger compartment of [Fig.l].

[0027] [Fig. 1] represents a vehicle 10 according to the invention. For example, the vehicle 10 is a motor vehicle.

[0028] The vehicle 10 comprises a passenger compartment 12 in which seats 14 are arranged, intended to accommodate passengers of the vehicle 10.

[0029] In the remainder of the description, the terms “front”, “rear”, “left”, “right”, “top”, “bottom”, “longitudinal” and “transverse” are understood to refer to the usual orientation of vehicles.

[0030] In the remainder of the description and unless specifically indicated, the term “passenger” refers indifferently to a driver passenger and a non-driver passenger.

[0031] With reference to Figures 1 and 2, the passenger compartment 12 comprises a plurality of interior trim elements intended to furnish the passenger compartment of the vehicle 10 and forming for example a floor, a ceiling light, a door panel, a dashboard or a central console.

[0032] The passenger compartment 12 is delimited in height by a floor 18, on which the seats 14 and a ceiling light (not visible) are fixed, and transversely by door panels 20.

[0033] The seats 14 are distributed in rows 22A, 22B, each row 22A, 22B of seats comprising at least two seats 14 aligned transversely. The seats 14 of the same row 22A, 22B of seats are for example spaced transversely from each other.

[0034] The vehicle 10 comprises a front row 22A and at least one rear row 22B.

[0035] For example, in the embodiment shown in Figures 1 and 2, the vehicle 10 includes a front row 22A of seats including a left front seat, designated by the reference numeral 14A, and a right front seat, designated by the reference numeral 14B, and a rear row 22B of seats disposed behind the front row 22A, and including a left rear seat, designated by the reference numeral 14C, and a right rear seat, designated by reference 14D

[0036] The vehicle 10 comprises a dashboard 24 provided with a steering wheel 26 arranged opposite a seat 14 of the front row 22A, said seat 14 being intended for the driver of the vehicle. In the embodiment of FIGS. 1 and 2, the steering wheel 26 is arranged in front of the front left seat 14A.

[0037] For example, the dashboard 24 is also provided with a display device 27 comprising a screen 28, in particular a touch screen 28, forming a human-machine interface. Said display device 27 can for example be used to display information concerning the vehicle, such as its speed or its position, or equipment of the vehicle, such as an air conditioning system or a radio system.

[0038] Preferably, the vehicle 10 further comprises at least one noise reduction system (not shown) associated with at least one zone of the passenger compartment 12, called the quiet zone.

[0039] For example, each seat 14 is associated with a noise reduction system. Such systems are known and comprise, for example, loudspeakers arranged on the seats or on the upholstery elements and configured to reduce ambient noise.

[0040] The vehicle 10 further comprises a communication device 30 configured to facilitate communication between several passengers of the vehicle 10 and an electronic control device 31 connected to the communication device 30, for example via a wireless link (not shown).

[0041] The communication device 30 comprises at least one actuation module 32 and at least one signaling module 34 comprising a light source 36.

[0042] Preferably, the communication device 30 comprises a plurality of actuation modules 32 and a plurality of signaling modules 34.

[0043] Each actuation module 32 is associated with at least one given signaling module 34, preferably with several given signaling modules 34, as will be explained later.

[0044] Each actuation module 32 is intended to be actuated by a given passenger of the vehicle 10.

[0045] Preferably, as shown in [Fig.l], the communication device 30 comprises as many actuation modules 32 as there are places for passengers in the vehicle 10, that is to say as many actuation modules 32 as there are seats 14.

[0046] Each actuation module 32 is here associated with a given seat 14.

[0047] Each actuation module 32 comprises at least one actuator. The actuator is for example chosen from a haptic actuator, such as a button, in particular a push button, a touch screen, a motion sensor or a touch sensor, in particular integrated on a surface of the seat.

[0048] An actuation module 32 may comprise a single actuator or several actuators. For example, an actuation module 32 may comprise several actuators, each actuator making it possible to transmit an actuation instruction to a given signaling module 34.

[0049] The actuation modules 32 may be identical for all the seats 14 or may be different depending on the seat 14 with which they are associated.

[0050] Each actuation module 32 is arranged on a trim element, on a seat 14 or on the steering wheel 26.

[0051] For example, in the embodiment of [Fig. 1], an actuation module 32 in the form of a push button is arranged on each seat 14, for example on a side of said seat 14.

[0052] Other types or locations of actuation modules 32 are conceivable.

[0053] In a variant not shown, the actuation module 32 associated with the driver's seat 14A is arranged on the steering wheel 26, for example in the form of a push button.

[0054] In a variant not shown, the actuation module 32 associated with the driver's seat 14A is formed by the touch screen 28 of the display device.

[0055] In a variant not shown, the actuation modules 32 associated with the seats 14 of the front row 22A are arranged on the dashboard 24, for example in the form of push buttons.

[0056] Each actuation module 32 is configured to emit at least one actuation instruction from a signaling module 34 with which it is associated.

[0057] Preferably, at least one actuation module 32 is capable of emitting a plurality of actuation instructions.

[0058] According to a particular embodiment, said actuation module 32 is configured to emit an actuation instruction from a list of predetermined actuation instructions.

[0059] The choice of the actuation instruction from the list depends for example on the force applied to the actuation module 32 by a user, the number of times the actuation module 32 is actuated in a given period of time, the gesture made by the passenger, the actuator used when the actuation module 32 comprises several, etc.

[0060] Each signaling module 34 is installed inside the passenger compartment 12 of the vehicle 10.

[0061] Each signaling module 34 is capable of emitting a light signal having at least one optical characteristic. The optical characteristic of the light signal is chosen, for example, from the wavelength, the luminous flux, a frequency of variation of the luminous flux and a luminous intensity. The wavelength of the light signal belongs to the visible range, that is to say that the wavelength is between 400 nm and 700 nm. The term "luminous flux" means the quantity of light emitted in all directions. "Luminous intensity" means the quantity of light emitted in a given direction.

[0062] Preferably, the communication device 30 comprises a plurality of signaling modules 34.

[0063] Each signaling module 34 is intended to allow communication between two passengers of the vehicle 10 by means of the emitted light signal. It is thus said that each signaling module 34 is capable of connecting a first passenger, called the transmitting passenger, and a second passenger, called the receiving passenger. The first and second passengers can thus communicate with each other by means of the emitted light signal.

[0064] Each signaling module 34 comprises at least one light source 36 capable of emitting the light signal.

[0065] Each light source 36 comprises a plurality of light-emitting diodes 40 or LEDs (for “Light-Emitting Diode” in English), arranged in the form of a set of LEDs 40.

[0066] Preferably, the LED assembly 40 forms an LED strip or an LED matrix.

[0067] Advantageously, the light-emitting diodes 40 of the light source 36 are capable of being selectively activated. For example, in the case of an LED matrix, the light-emitting diodes are capable of being selectively activated so as to display a pictogram, for example a smiling face.

[0068] Each light source 36 is arranged on at least one trim element of the passenger compartment and / or at least one seat 14 of the vehicle.

[0069] For example, the light source 36 is arranged on the ceiling light, the floor 18, the dashboard 24 or a door panel 20.

[0070] For example, the light source 36 is arranged on the back of a seat 14 so as to be visible to a passenger seated behind said seat 14.

[0071] For example, the light source 36 comprises an LED strip extending at least partly in a longitudinal direction of the vehicle 10 and going from the front row 22A to the rear row 22B. The LED strip is for example arranged on a door panel 20, on the ceiling light or on the floor 18.

[0072] In the embodiment of Figures 1 and 2, the communication device 30 comprises: - a first light source 140 in the form of an LED strip, arranged on the door panels on the left side of the vehicle (i.e. here on the driver's side) and making it possible to connect the driver and the passenger seated behind; - a second light source 142 in the form of an LED strip, arranged on the door panels on the right side of the vehicle, and making it possible to connect the two passengers on said right side; - a third light source 144 in the form of an LED strip, arranged on the floor and allowing the driver to connect with the right rear passenger, and - a fourth light source 146 in the form of an LED strip, arranged on the floor and making it possible to connect the non-driving front passenger with the left rear passenger.

[0073] The light sources thus form light paths between two passengers, allowing them to communicate silently.

[0074] Numerous arrangements of the light sources 36 are possible.

[0075] For example, when the light source 36 is an LED strip, said strip can be arranged so as to have a non-rectilinear profile, for example a wavy profile, or to represent a figurative pattern, such as a branch with flowers.

[0076] As a variant, in an embodiment not shown, the communication device 30 comprises four signaling modules 34, formed of two LED matrices arranged at the rear of the front seats 14A, 14B, so as to be visible to the passengers seated in the rear, and of two LED matrices arranged on the dashboard, each facing a given seat 14A, 14B of the front row 22A.

[0077] According to a particular embodiment, the communication device 30 comprises a plurality of LED matrices, capable of representing a figurative pattern, such as a branch with flowers, and / or of producing visual animations.

[0078] Alternatively or additionally, the communication device 30 comprises at least one screen capable of emitting visual signals, such as images and / or animations.

[0079] Each signaling module 34 is configured to switch between an idle state and at least one communication state, preferably a plurality of communication states distinct from each other.

[0080] When the signaling module 34 is in a rest state, the corresponding light source 36 is off, i.e. it does not emit radiation in the visible range.

[0081] When the signaling module 34 is in a communication state, the corresponding light source 36 emits a light signal suitable for being seen by at least one passenger of the vehicle, in particular by the receiving passenger.

[0082] The light signal emitted thus allows several passengers to communicate with each other.

[0083] A combination of optical characteristics is associated with each communication state.

[0084] Preferably, the optical characteristics associated with each communication state can be modified by a user, for example at the display device 27. For example, the brightness, the flashing frequency and / or the The color of the light signal can be changed.

[0085] According to a preferred embodiment, each signaling module 34 is configured to switch between a first communication state, announcing that a first passenger wants to communicate with a second passenger, and a second communication state, announcing that the second passenger also wants to communicate with the first passenger.

[0086] For example, each signaling module 34 is configured to switch between the first communication state and the second communication state following simultaneous actuation by the first passenger and the second passenger of their associated actuation module 32.

[0087] For example, in the case of one or more LED matrices, said matrices are capable of producing a visual animation and / or a figurative pattern following the simultaneous actuation by the first passenger and by the second passenger of their associated actuation module 32.

[0088] As an example, some communication states are described below:

[0089] - in a first communication state, the light source 36 emits a continuous radiation having an intensity between 250 lumen (1m) and 500 1m, and in a second communication state, the light source 36 emits continuous radiation having an intensity between 500 1m and 1000 1m;

[0090] - in a first communication state, the light source 36 emits a continuous radiation having a wavelength between 560 nm and 587 nm, corresponding to yellow-colored radiation, and in a second communication state, the light source 36 emits continuous radiation having a wavelength between 510 nm and 550 nm, corresponding to green-colored radiation;

[0091] - in a first communication state, the light source 36 emits a flashing radiation having a wavelength, the frequency of the flashing being typically between 0.2 Hz and 2 Hz and in a second communication state, the light source 36 emits continuous radiation.

[0092] The communication device 30 thus allows passengers to interact with each other, the communication not being limited exclusively to the sending of a light signal by one passenger to another, but encouraging exchanges between them.

[0093] Other communication states are conceivable, and those skilled in the art are able to choose the optical characteristics of the light signals corresponding to each communication state according to their needs, in particular according to the desired use.

[0094] Preferably, each actuation instruction is associated with a given light source 36 and with a communication state of said given source 36, each communication state communication corresponding to distinct optical properties of the light source 36.

[0095] For example, the transmitting passenger is able to select the receiving passenger with whom he wishes to communicate and to transmit an actuation instruction associated with the adapted light source 36.

[0096] For example, in the example of [Fig.2], if the driver wishes to communicate with the passenger seated behind him, he can issue an actuation instruction so as to switch the light source 140 to the communication state.

[0097] According to a given embodiment, a signaling module 34 is configured to remain in the communication state only when the actuation module 32 is actuated. For example, when the actuation module 32 comprises a push button, the signaling module 34 is configured to remain in the communication state only if the button is pressed.

[0098] According to another given embodiment, a signaling module 34 is configured to remain in the communication state for a given period of time after the actuation of the actuation module 32.

[0099] Preferably, said signaling module 34 is configured to automatically switch from a communication state to an idle state after a given period of time, typically between 30 seconds and five minutes, for example between one minute and two minutes. Thus, the signaling module 34 does not remain blocked in the communication state.

[0100] Advantageously, at least one signaling module 34 further comprises a sound device, capable of emitting a sound signal when said signaling module 34 switches to the communication state. The sound signal is for example a melody and makes it possible to discreetly attract the attention of the receiving passenger.

[0101] Advantageously, the communication device 30 further comprises at least one isolation module (not shown) capable of preventing the switching of at least one signaling module 34 from the idle state to a communication state.

[0102] Each isolation module is for example associated with a given seat 14 and is capable of being actuated by means of an actuator, said actuator being for example the actuating module or another actuator.

[0103] When the isolation module is activated by a given passenger, the signaling module(s) 34 configured to switch into a communication state, announcing that another passenger wants to communicate with said given passenger, are blocked in the idle state.

[0104] For example, in the embodiment of [Fig. 1], if the right rear passenger activates the isolation module associated with his seat 14D, the corresponding signaling modules 34 will not be able to switch to communication state and the light sources Associated miners 142, 144 will remain extinct.

[0105] Advantageously, each isolation module is associated with a light warning device 48 capable of emitting a light signal when the isolation module is activated.

[0106] For example, the light warning device 48 is arranged in the ceiling light, above the associated seat 14, or in the floor in front of or around the associated seat. Alternatively, the light warning device 48 is arranged on the seat, for example at a side or a headrest.

[0107] The light warning device 48 comprises, for example, at least one light-emitting diode, in the form of an LED spotlight or an LED strip.

[0108] In the example of [Fig.2], the rear seats 14C, 14D have for example LED spotlights located at the headrest.

[0109] Alternatively, the light warning device 48 is an LED strip arranged on the floor and surrounding the associated seat, so as to visualize a quiet zone.

[0110] The light warning device 48 makes it possible to warn other passengers that the passenger has activated the associated isolation module and that he does not wish to communicate with them at this time.

[0111] The light warning device 48 is preferably configured to emit a continuous light signal as long as the isolation module is activated.

[0112] According to a particular embodiment, when the vehicle 10 comprises noise reduction systems, these are preferably each associated with a given insulation module, so that the activation of the insulation module simultaneously causes the activation of the associated noise reduction system and / or conversely, the activation of the noise reduction system simultaneously causes the activation of the associated insulation module.

[0113] The electronic control device 31 comprises a receiving module 50 configured to receive the actuation instruction transmitted by the or one of the actuation modules 32.

[0114] The electronic control device 31 further comprises a selection module 51 configured to determine, as a function of the actuation instruction, a corresponding switching instruction. For example, the selection module 51 is capable of associating the actuation instruction with a switching instruction in a predetermined list.

[0115] The electronic control device 31 further comprises a control module 52 configured to transmit the selected switching instruction to the associated signaling module 34.

[0116] In the example of [Fig.l], the electronic control device 31 comprises an information processing unit 54 formed for example by a memory 56 and of a processor 58 associated with the memory 56. The electronic control device 31 comprises a transceiver 60 configured in particular to receive, for example via wireless data links 62, the actuation instructions, sent by the actuation module(s) 32 to the reception module 50, and / or to transmit, in the opposite direction, switching instructions from the control module 52, these instructions being in particular intended for at least one signaling module 34.

[0117] In the example of [Fig. 1], the reception module 50, the selection module 51 and the control module 52 are each produced in the form of software, or a software brick, executable by the processor 58. The memory 56 of the electronic control device 31 is then capable of storing software for receiving actuation instructions, software for selecting a switching instruction capable of establishing at least one switching instruction from the received actuation instruction and control software capable of transmitting each switching instruction to the corresponding signaling module 34. The processor 58 is then capable of executing each of the software among the reception software and the control software.

[0118] In a variant not shown, the reception module 50, the selection module 51 and the control module 52 are each produced in the form of a programmable logic component, such as an FPGA (Field Programmable Gate Array), or in the form of a dedicated integrated circuit, such as an ASIC (Application Specific Integrated Circuit).

[0119] When the electronic control device 31 is produced in the form of one or more software programs, that is to say in the form of a computer program, it is also capable of being recorded on a medium, not shown, that is readable by a computer. The computer-readable medium is, for example, a medium capable of storing electronic instructions and of being coupled to a bus of a computer system. By way of example, the readable medium is an optical disk, a magneto-optical disk, a ROM memory, a RAM memory, any type of non-volatile memory (for example EPROM, EEPROM, FLASH, NVRAM), a magnetic card or even an optical card. A computer program comprising software instructions is then stored on the readable medium.

[0120] The operation of the communication device 30 in the vehicle 10 according to the invention will now be described.

[0121] The vehicle 10 travels on a track and has on board several passengers seated on the seats 14. For example, the vehicle 10 accommodates a driver passenger, seated behind the steering wheel 26, a passenger seated in the front and two passengers seated in the rear.

[0122] When a first passenger wishes to communicate with a second passenger of the vehicle 10, the first passenger activates the actuation module 32 associated with his seat 14.

[0123] For example, when the actuation module 32 comprises a push button, the first passenger presses said push button.

[0124] Said actuation module 32 then transmits an actuation instruction to the electronic control device 31, and in particular to the reception module 50.

[0125] The selection module 51 then determines, based on the actuation instruction, a corresponding switching instruction.

[0126] Then, the control module 52 transmits the selected switching instruction to the corresponding signaling module 34.

[0127] The light source 36 of said signaling module 34 then passes from a rest state to a communication state and emits a light signal, visible to the second passenger.

[0128] The first passenger and the second passenger can thus communicate silently, without disturbing the other passengers.

[0129] According to a particular embodiment, the second passenger can also actuate his actuation module 32, so as to switch the light source 36 into a second communication state.

[0130] This allows, for example, the first passenger to see that the second passenger has seen the light signal intended for him.

[0131] Such an embodiment is particularly advantageous when one of the passengers is a child seated in the rear. In this case, it is not always easy for a passenger seated in the front to communicate with him. By each actuating his respective actuation module 32 so as to activate the light source 36, the child and the passenger in the front can interact, which can reassure the child.

[0132] When the communication device 30 comprises an isolation module, a passenger can activate it if he wishes not to interact temporarily with the other passengers. The other passengers will then no longer be able to communicate with him by means of the signaling modules 34. Advantageously, a light warning device 48 emits a light signal when the isolation module is activated, so as to warn the other passengers.

[0133] The communication device 30 according to the invention is thus an effective means of enabling non-verbal communication between passengers, and thus preventing the passenger compartment 12 of the vehicle 10 from becoming too noisy.

[0134] The signaling modules 34 in the form of a set of LEDs 40 are inexpensive and can easily be integrated into a passenger compartment 12. They also allow innovative communication between passengers.

[0135] For example, when a light source 36 is formed from an LED strip, the latter makes it possible to visualize the link between the passengers by means of a light path.

[0136] Such a communication device 30 is particularly useful when one of the passengers is a child. The communication device 30 thus makes it possible to reassure the child, without the driver or a front passenger needing to turn around to interact with the child.

[0137] The use of LED type light sources 36 also makes it possible to easily choose the optical properties thereof according to the usage requirements. For example, depending on the location of the light source 36, the brightness and / or the flashing frequency may for example be adapted, so as not to disturb the driver's vigilance.

[0138] The invention is not limited to the exemplary embodiments and variants described above. Other exemplary embodiments and other variants are conceivable.

[0139] For example, according to a variant, the choice of the actuation instruction is not made at the level of the actuation module 32, but at the level of the electronic control device 31, in particular at the level of the selection module 51.

[0140] Following its actuation by a passenger, the actuation module 32 then transmits an actuation signal to the reception module 50 of the electronic control device 31. The selection module 51 then determines, as a function of said signal, an actuation instruction from a list of predetermined actuation instructions, then associates a switching instruction with it, as described previously.
