Description

Title of the invention: Method for olfactory identification of a driver of a motor vehicle, associated device and motor vehicle.

[0001] The invention relates to the identification of a driver of a motor vehicle.

[0002] There is a need to make the identification of a driver of a motor vehicle both simple and secure.

[0003] For this purpose, the invention relates to a method for identifying a driver of a motor vehicle comprising a passenger compartment, implemented in the motor vehicle, characterized in that it comprises the following steps: • For example, entry of the driver into the motor vehicle (for example, into the passenger compartment of the motor vehicle), • Reception, from an olfactory sensor (in other words: electronic nose), of identifiers of the first volatile chemical reference compounds (present) in the passenger compartment, then • First determination of a reference signature of the driver from the identifiers of the first volatile chemical reference compounds, then • (For example, before, after or during the step of receiving the identifiers of the first volatile chemical reference compounds) Commanding a restitution (for example, a display) of a security question via a human-machine interface of the motor vehicle (in other words; Sending a command to restore a security question to a human-machine interface), then • Receiving a reference response (to the security question), from (in other words: via) a human-machine interface (which may be the human-machine interface) of the motor vehicle, and storing the reference response, • Then, for example, detection of a locking or a disconnection of the motor vehicle (for example from a received instruction), (and, for example, the driver leaving the motor vehicle), • Then, for example, detection of unlocking or switching on the motor vehicle (for example from a received instruction), (then, for example, entry of the driver into the motor vehicle), • Then (for example, after the step of determining the reference signature, and / or after the step of receiving a reference response), reception, from an olfactory sensor (for example, by the olfactory sensor) (in other words: an electronic nose), identifiers of the first common volatile chemical compounds (present) in the passenger compartment, • Determination of a current signature of the driver from the identifiers of the first common volatile chemical compounds, then • First comparison of the driver's current signature with a reference signature of the driver.

[0004] Thus, thanks to identification based on smell and the memorization of the reference response to the security question, the identification of the driver is simple and secure.

[0005] According to one embodiment, the method further comprises, after the first comparison step, a data storage step, the data storage being conditional on the first comparison step having determined that the current signature of the driver corresponds to the reference signature of the driver.

[0006] Thus, thanks to the invention, the driver can be identified simply and securely, to ensure that the data is stored or collected only with his consent (previously given, and the method can include a step of receiving, from the human-machine interface, consent).

[0007] Alternatively, driver identification may provide access to other functions of the motor vehicle.

[0008] The steps of receiving identifiers of first common volatile chemical compounds, determining a current signature, first comparing, and storing the data may be repeated.

[0009] According to one embodiment, the method further comprises the following steps: • After receiving the reference response (and for example, after detecting unlocking or switching on the ignition of the motor vehicle), commanding a restitution (for example, a display) of the security question via a human-machine interface (which may be the human-machine interface) of the motor vehicle, then • Receiving a first current response (to the security question), via a human-machine interface (which may be the human-machine interface), then • Second comparison of the first current response with the reference response, The storage step being conditioned on the second comparison step having determined that the first current response corresponds (for example, is equal to) the reference response, for example, if the current signature of the driver does not correspond to the reference signature of the driver or, in all cases.

[0010] Alternatively, the memorization step is not conditional on a response to the reference question.

[0011] According to one embodiment, the method according to the invention further comprises the following steps: • After storing the data, ordering a restitution (for example, a display) of the security question via a human-machine interface (which may be the human-machine interface) of the motor vehicle, then • Receiving a second current response (to the security question), via a human-machine interface, then • Third comparison of the second current response with the reference response, then • Detection, by the olfactory sensor, of identifiers of second volatile chemical reference compounds in the passenger compartment, then • Second determination (in other words: modification) of the driver's reference signature from the identifiers of the second reference volatile chemical compounds, The second determination step being conditional on the third comparison step having determined that the second current response corresponds (for example, is equal to) the reference response.

[0012] Alternatively, the reference signature may be modified in another way, for example by authenticating the driver by other means.

[0013] For example, storing the data may be followed by sending the data to a remote server.

[0014] There are various olfactory sensors. For example, the invention uses the one described in the article: “Jirayupat C et al. Breath odor-based individual authentication by an artificial olfactory sensor system and machine learning. Chemical Communications (Cambridge, England), 30 May 2022, 58(44):6377-6380”.

[0015] The sensor may be positioned, for example, on a steering wheel of the motor vehicle or on a dashboard of the motor vehicle, or any other location close to the driver.

[0016] The sensor may, for example, detect volatile chemical compounds in a driver's breath or on the driver's skin.

[0017] For example, the data includes data modified during a movement of the motor vehicle, the step of storing the data being repeated during the movement of the vehicle.

[0018] According to one embodiment, the data modified during the movement of the motor vehicle comprise: • A geolocation of the motor vehicle (received, for example, from a satellite geolocation module of the motor vehicle), and / or • A motor vehicle speed (received, for example, from a motor vehicle speed sensor).

[0019] According to one embodiment, the data comprising a vehicle identifier, for example called “VIN” (in English “vehicle identification number”) according to the ISO 3779:2009 and ISO 3780:2009 standards.

[0020] The current signature or the reference signature can be determined by an artificial intelligence model (from the identifiers of the first or second current volatile chemical compounds for the current signature, and from the first or second identifiers of the reference volatile chemical compounds for the reference signature), for example an artificial neural network, or by any computer program.

[0021] For example, the current signature of the driver corresponds to the reference signature of the driver if a distance between the current signature of the driver and the reference signature of the driver is less than a threshold, the current signature of the driver and the reference signature of the driver being a vector.

[0022] Alternatively, other representations and other matching criteria may be used.

[0023] The invention also relates to a computer program comprising instructions executable by a microprocessor or a microcontroller or a computer, for implementing the steps of the method according to the invention, when it is executed by the microprocessor or the microcontroller or the computer.

[0024] The method according to the invention can be implemented by an electronic device (or a motor vehicle). The invention therefore also relates to an electronic device (or a motor vehicle) configured to implement the steps of the method according to the invention, as well as a motor vehicle comprising the electronic device.

[0025] The characteristics and advantages of the computer program, the electronic device, and the vehicle are identical to those of the method according to the invention (without it being necessary to repeat them here).

[0026] When the electronic device, the motor vehicle (or another element) is “configured to” (or “capable of”) performing or implementing a step or an operation, this implies, for example, that the element comprises means for performing the step or the operation. The means preferably comprise electronic means, for example a computer program, data in memory, specialized electronic circuits, a data bus, a microprocessor and / or a microcontroller.

[0027] Other characteristics and advantages of the present invention will appear more clearly on reading the detailed description which follows, comprising embodiments of the invention given as non-limiting examples and illustrated by the appended drawings, in which: • [Fig.l] represents an electronic device and a motor vehicle, according to an embodiment of the invention, in top view, • [Fig.2] represents an implementation of the method according to the invention, according to a example of embodiment, by the electronic device and the motor vehicle of [Fig.l],

[0028] In [Fig.l], certain elements are, of course, seen through transparency.

[0029] Detailed description of an exemplary embodiment of the invention, with reference to figures 1 and 2.

[0030] [Fig.l] represents a motor vehicle 100. The motor vehicle 100 comprises a passenger compartment 150 and a microprocessor 110. Furthermore, the microprocessor 110 is connected to the following components located in the vehicle: • An olfactory sensor 120 located in the passenger compartment 150, • A 130 satellite geolocation module • A 160 speed sensor, • A 140 touch screen in the 150 passenger compartment.

[0031] At step S00 [Fig.2], a driver enters the passenger compartment 150 for the first time.

[0032] In step S10, the microprocessor 110 receives, from the olfactory sensor 120, identifiers of reference volatile chemical compounds in the passenger compartment 150.

[0033] For example, the olfactory sensor 120 is such as that described in the following article: “Jirayupat C et al. Breath odor-based individual authentication by an artificial olfactory sensor System and machine learning. Chemical Communications (Cambridge, England), 30 May 2022, 58(44):6377-6380”.

[0034] The olfactory sensor 120 can be positioned, for example, on a steering wheel or on a dashboard of the motor vehicle 100.

[0035] The olfactory sensor 120 may, for example, detect volatile chemical compounds in a driver's breath or on the driver's skin.

[0036] In step S20, the microprocessor 110 determines a reference signature of the conductor from the reference volatile chemical compounds, using a computer program 111.

[0037] In step S30, the microprocessor 110 commands a display of a security question via the touch screen 140.

[0038] In step S40, the microprocessor 110 receives a reference response to the security question, via the touch screen 140.

[0039] In step S50, the driver exits the motor vehicle 100 and the microprocessor 110 detects a locking of the motor vehicle 100.

[0040] In step S60, the microprocessor 110 detects an unlocking of the motor vehicle 100 and the driver re-enters the motor vehicle 100.

[0041] In step S70, the microprocessor 110 receives, from the olfactory sensor 120, identifiers of volatile chemical compounds commonly present in the passenger compartment 150.

[0042] In step S80, the microprocessor 110 determines a current signature of the driver from the current volatile chemical compounds, using the computer program 111.

[0043] In step S90, the microprocessor 110 compares the current signature of the driver with a reference signature of the driver.

[0044] In step S100, the microprocessor 110 commands a display of a security question via the touch screen 140.

[0045] In step S1 10, the microprocessor 110 receives a first current response to the security question, via the touch screen 140.

[0046] In step S120, the microprocessor 110 compares the first current response with the reference response.

[0047] In step S130, the microprocessor 110 stores data if: • In step S90, the microprocessor 110 has determined that the current signature of the driver corresponds to the reference signature of the driver, and • In step S120, the microprocessor 110 has determined that the first current response is equal to the reference response.

[0048] For example, the data includes: • A geolocation of the motor vehicle 110 received, by the microprocessor 110, from the satellite geolocation module 130, and • A speed of the motor vehicle, 110, received, by the microprocessor 110, from the speed sensor 160.

[0049] According to one embodiment, the data comprises a vehicle identifier, for example called “VIN”.

[0050] In step S140, the microprocessor 110 sends the data to a remote server 200 for use of this data by the remote server 200, for example to determine the maintenance needs of the motor vehicle.

[0051] Steps S130 and S140 may be repeated throughout the movement of the motor vehicle 110.

[0052] The microprocessor 110 can repeat steps S100 to S120, S10, then S20 if the current response is equal to the reference response in order to modify the reference signature.

[0053] Steps S60 to S140 may then be repeated.
