Description

Title of the invention: Method and device for controlling an electronic device located in a room from an on-board control device of a vehicle technical field

[0001] The present invention relates to the remote control of electronic devices. More particularly, the present invention relates to the control of an electronic device located in a room such as a house or business premises from an on-board control device in a vehicle. Technological background

[0002] Residential premises such as detached houses or apartments or professional premises are equipped with multiple electronic devices.

[0003] Some of these electronic devices can be implemented to secure these premises, to control access to these premises or to know the status of certain electronic devices located in these premises such as the status of a fire alarm device, a heating or ventilation device or a shutter closing system.

[0004] These electronic devices can be configured to be controlled by control devices such as remote controls or control units installed in these premises.

[0005] These control devices may be wireless to facilitate their installation and control of these electronic devices within the premises. However, when the user gets into their vehicle and leaves their home, they lose control of these electronic devices. In particular, they can no longer control access to their home while in their vehicle and, for example, remotely grant access to their home.

[0006] One of the problems solved is to control electronic devices located in a residential or professional premises from an on-board control device of a vehicle. Summary of the invention

[0007] One object of the present invention is to resolve at least one of the drawbacks of the technological background.

[0008] An object of the present invention is to improve the remote control of electronic devices located in premises.

[0009] According to a first aspect, the present invention relates to a method of controlling an electronic device located in a room from a control device embedded in a vehicle, said process being implemented by at least one processor and comprising the following steps: - reception, by the control device, of a first data point representative of at least one operating state of the electronic device; - control of an on-board vehicle data rendering system to render the first data; - obtaining a second piece of data representing an action to be carried out by the electronic device; - transmission of the second data to the electronic device, the electronic device performing the action following reception of the second data.

[0010] The method is advantageous because it is simple to use by a vehicle user who can thus interact remotely with electronic devices installed in his home or business premises.

[0011] According to a particular and non-limiting example of embodiment, the second data is obtained from an action by a vehicle user on an on-board human-machine interface of the vehicle.

[0012] According to a particular and non-limiting embodiment, the first data and the second data are encrypted.

[0013] This example is advantageous because it allows the exchange of first and second data between the electronic device and the control device to be secured.

[0014] According to a particular and non-limiting embodiment, the first data represents an alert message from an alert system installed in the premises, the data rendering system displays the alert message on a screen in the vehicle and / or emits a sound signal on a loudspeaker in the vehicle and the second data represents a stop of the alert.

[0015] This example is advantageous because it allows a user to be informed of a fire alarm or an intrusion in their premises. It also allows the user to remotely stop an audible alarm message that might be emitted in the premises.

[0016] According to a particular and non-limiting embodiment, the first data represents a request for access to the premises, the data rendering system displays an access request message on a screen in the vehicle and / or emits a sound signal on a loudspeaker in the vehicle and the second data represents a refusal or an authorization of access.

[0017] This example is advantageous because it allows a vehicle user to control access to a room. A person present at the entrance to the room can, for example, press an intercom at the entrance to request access. The first data is then transmitted to the vehicle's on-board control device. A vehicle user can then accept or deny access to the room to this person via The human-machine interface. The second piece of data is generated based on whether access is denied or granted. This second piece of data is sent to the access control device, which then grants or denies access to the premises based on the second piece of data received.

[0018] According to a second aspect, the present invention relates to a control device for an electronic device located in a room, said control device being mounted in a vehicle and comprising a memory associated with at least one processor configured for the implementation of steps of the process according to the first aspect of the present invention.

[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 control system for an electronic device located in a room comprising a control device for the electronic device according to the second aspect of the present invention.

[0021] According to a fifth 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.

[0022] 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.

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

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

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

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

[0027] Other features and advantages of the present invention will become apparent from the description of the non-limiting embodiments of the present invention below, with reference to the attached Figures 1 to 3, in which:

[0029] [Fig.2] schematically illustrates a control device for an electronic device located in a room, according to a particular and non-limiting embodiment of the present invention; and

[0030] [Fig.3] illustrates a flowchart of the different stages of a control process of a electronic device located in a room, according to a particular and non-limiting embodiment of the present invention. Description of the implementation methods

[0031] A method and a control device for an electronic device located in a room will now be described in what follows with joint reference to Figures 1 to 3. The same elements are identified with the same reference signs throughout the description that follows.

[0032] According to a particular and non-limiting embodiment of the present invention, a control device embedded in a vehicle receives a first data point representing at least one operating state of an electronic device located in a room. An on-board data rendering system of the vehicle is controlled to render the first data point by displaying information relating to this first data point and / or by emitting an audible signal inside the vehicle's passenger compartment. A user inside the vehicle is thus informed of the receipt of the first data point and its semantic content. A second data point representing an action to be performed by the electronic device is obtained, for example, following an action by a user on an on-board human-machine interface of the vehicle.The second piece of data is sent to the electronic device, which then performs the action upon receiving the second piece of data.

[0033] Fig. 1 schematically illustrates an architecture of a control system 1 for an electronic device located in a room, according to a particular and non-limiting embodiment of the present invention.

[0034] Vehicle 10 corresponds, for example, to a vehicle with an internal combustion engine, an electric motor(s), or a hybrid vehicle with an internal combustion engine and one or more electric motors. Vehicle 10 thus corresponds, for example, to a land vehicle, such as a car, a truck, a bus, or a motorcycle. Finally, vehicle 10 corresponds to an autonomous or non-autonomous vehicle, that is to say, a vehicle operating according to a predetermined level of autonomy or under the total supervision of the driver.

[0035] Fig. 1 also illustrates a data exchange system between a control device 2 on board the vehicle 10 which is described in relation to Fig. 2 and an electronic device 3 removed from the vehicle 10 and located in a room for example in a dwelling or a professional premises.

[0036] According to one embodiment, the system further comprises a mobile communication device 11, for example, a smartphone, a tablet, or a connected object such as a smartwatch. The mobile communication device 11 includes communication interfaces for receiving first data transmitted by the electronic device 3, for transmitting this first data to the control device 2, for receiving second data transmitted by the control device 2, and for transmitting this second data to the electronic device 3. The mobile communication device 11 may further comprise one or more installed mobile applications to enable the reception and transmission of the first and second data with the control device 2 and the electronic device 3.

[0037] The control device 2 and the electronic device 3 and the mobile communication device 11 are remote from each other and exchange data via a communication network infrastructure.

[0038] The electronic device 3 advantageously corresponds to a data processing device configured to process data, for example, first data stored in one of its memories and / or obtained from a sensor located locally, or second data received which may be transmitted by the mobile communication device 11 or by the control device 2. The electronic device 3 includes communication interfaces for transmitting, to the control device 2 or optionally to the communication device 11, first data representative of at least one operating state of the electronic device 3 and for receiving second data transmitted by the control device 3 or, optionally, by the mobile communication device 11. The second data represents an action to be performed by the electronic device 3.The electronic device 3 is also configured to perform an action upon receiving a second piece of data representative of said action.

[0039] The vehicle 10 includes, for example, one or more communication antennas 110 connected to a telematic control unit, known as a TCU (Telematic Control Unit) and also called a BTA (Autonomous Telematics Unit) or BSRF (Radio Frequency Servicing Unit). The TCU is also connected in communication with the control device 2. The antenna(s) 110, the TCU, and the control device 2 form, for example, a multiplexed architecture for providing various services useful for the proper functioning of the vehicle 10 and for assisting the driver and / or passengers in controlling the vehicle 10, for example, by displaying regulatory speed information on a display device installed in the vehicle 10.

[0040] The control device 2 and the TCU unit communicate and exchange data with each other via one or more computer buses, for example a CAN (Controller Area Network) type communication bus, CAN FD (Controller Area Network Flexible Data-Rate), FlexRay (according to ISO 17458) or Ethernet (according to ISO / IEC 802-3).

[0041] The control device 2 further includes a human-machine interface preferably located in a dashboard of the vehicle 10. The human-machine interface includes a sound and / or visual rendering system of the first data received by the control device 2 and an input system configured to propose possible actions to a vehicle user based on the first data received, to select one of these actions and to generate second data based on the selected action.

[0042] According to a particular and non-limiting embodiment, the sound and / or visual rendering system 4 includes a screen which may be touch-sensitive.

[0043] According to a particular and non-limiting embodiment, the input system may include areas of a touch screen possibly combined with one or more buttons or a selection wheel.

[0044] According to a particular and non-limiting embodiment, the communication network infrastructure includes at least one communication equipment 121 of the type relay antenna of a cellular network or roadside unit, known as UBR.

[0045] According to one embodiment, the communication equipment 121 is, for example, connected to a cloud 12 of the communication network infrastructure via a wired link. Data is then exchanged between the control device 2 and the electronic device 3 via a wireless connection between the communication antenna 10 and the communication equipment 121 and via a wired connection between the communication equipment 121 and the electronic device 3.

[0046] According to another embodiment, the communication equipment 121 is, for example, connected to a cloud 12 of the communication network infrastructure via a wireless link. Data is then exchanged between the control device 2 and the electronic device 3 via a wireless connection between the communication antenna 110 and the communication equipment 121 and via a wireless connection between the communication equipment 121 and the electronic device 3.

[0047] According to another variant, the wireless communication between the communication antenna 110 and the communication equipment 121 is direct.

[0048] According to another variant, the wireless communication between the communication antenna 110 and the communication equipment 121 passes through the mobile communication device 11.

[0049] The exchange of data between the control device 2 and the electronic device 3 uses, for example, one of the following communication systems:

[0050] - a vehicle-to-V2I infrastructure communication system (from the English "vehicle- to-infrastructure"), for example based on the 3GPP LTE-V or IEEE 802.1 lp standards of ITS G5.

[0051] - a cellular network type communication system, for example a network of LTE type (from the English "Long-Term Evolution" or in French "Evolution à long terme"), LTE-Advanced (or in French LTE-avancé) LTE 4G or 5G; or

[0052] - a Wifi-type communication system according to IEEE 802.11, for example according to IEEE 802.1 In or IEEE 802.1 lake.

[0053] A process for controlling the electronic device 3 located in the room from the control device 2 on board the vehicle 10 is advantageously implemented by one or more processors on board the vehicle 10.

[0054] In a first operation, a first data representative of at least one operating state of the electronic device 3 is received by the control device 2 via the communication network infrastructure described above.

[0055] In a second operation, the control device 2 controls the vehicle 10's on-board data rendering system 4 to render the first received data, i.e., for example, to display information representative of the first data on a screen and / or to emit a sound signal inside the vehicle 10 which is representative of the first received data.

[0056] In a third operation, a second data representative of an action to be carried out by the electronic device 3 is obtained by the control device 2.

[0057] In a fourth operation, the control device 2 sends the second data to the electronic device 3. The electronic device 3 then performs the action represented by the second data following a reception of the second data.

[0058] According to a particular and non-limiting embodiment, the second data is obtained from an action by a vehicle user on the human-machine interface.

[0059] According to a particular and non-limiting embodiment, the reception of the first data and the transmission of the second data are encrypted by a known encryption method such as the DES (Data Encryption Standard) method or the AES (Advanced Encryption Standard) method for symmetric encryption or the RSA method (of inventors Rivest, Shamir and Adlerman) for asymmetric encryption (public key encryption).

[0060] According to a particular and non-limiting embodiment, the electronic device 3 is an alert system installed in the premises, such as a fire alarm system or an intrusion alarm system. The first piece of data then represents an alert message (fire or intrusion into the premises), and the second piece of data can be, for example, representative of the alarm being stopped. Upon receiving the second piece of data, the alert system stops the alarm.

[0061] According to a particular and non-limiting embodiment, the electronic device 3 is a room access control device. The first data point represents a request for access to the room, for example, by a user standing in front of the room's entrance door. The data rendering system displays an access request message on a vehicle screen and / or emits an audible signal on a vehicle speaker 10, and the second data point represents a refusal or authorization of access. The electronic device can then, for example, unlock the room's entrance door if the second data point represents authorization of access to the room, or emit a message regarding the refusal of access.

[0062] According to a particular, non-limiting embodiment, the electronic device 3 is a heating / air conditioning system, a blind closing system, or a lighting control system. The first data point can then represent a heating / air conditioning setpoint, a heating / air conditioning system malfunction, a blind closure status, or a room lighting status. The data rendering system can then display a heating / air conditioning setpoint, a message relating to the heating / air conditioning system malfunction, a blind closure status, a room lighting status, or emit an audible signal in the vehicle's passenger compartment related to the first data point.The second piece of data can represent a new heating / cooling instruction, a start or stop command for the heating / cooling system, a command to open or close shutters, or a command to turn the room lights on or off. The heating / cooling system can then apply the... The new instruction represented by the second data received allows the shutter management system to close or open the shutters, or the room's lighting management system to turn the room's lights on or off.

[0075] According to a further particular embodiment, the control device 2 can provide output signals to one or more external devices, such as a display screen 24, one or more loudspeakers 25, and / or other peripherals 26, respectively via output interfaces 27, 28, and 29. In one variant, one or more of the external devices is integrated into the control device 2. The display screen 24, for example, corresponds to a screen, whether touch-sensitive or not. The screen 24 can be used to display information representing a first data point. The loudspeakers 25 can also be used to trigger an audible alarm to warn a user of the vehicle 10 of a state of an electronic device 3 located in his or her living or professional premises.
