Description

Title of the invention: Method, device and system for controlling the use of an electric vehicle shared by several users Technical field

[0001] The present invention relates to methods, devices and systems for controlling the use of an electric vehicle shared by a plurality of users, in particular but not exclusively an electric motor vehicle. The present invention also relates to methods, devices and systems for communicating data for sharing an electric vehicle. Technological background

[0002] The rise in the standard of living and the fall in vehicle production costs have led to a very significant increase in the number of vehicles, particularly electric vehicles, owned by individuals. This increase in the number of vehicles leads to problems of air pollution (caused by the combustion of thermal engines and by the release of fine particles by tires and brakes), space occupation (significant need for parking spaces), in terms of infrastructure (charging stations for electric vehicles), etc.

[0003] It turns out that a private individual's vehicle is actually only used 20% of the time in reality, with a vehicle remaining parked for 80% of its lifespan on average. The cost associated with the actual use of a vehicle (acquisition cost, maintenance cost, cost of the infrastructure required for the vehicle) is therefore particularly high, especially if we only take into account the time the vehicle is actually used. Summary of the present invention

[0004] An object of the present invention is to solve at least one of the problems of the technological background described above.

[0005] An object of the present invention is, for example, to optimize the use of a vehicle, in particular an electric vehicle.

[0006] Another object of the present invention is, for example, to reduce the costs associated with the use of a vehicle, in particular an electric vehicle.

[0007] According to a first aspect, the present invention relates to a method for controlling the use of an electric vehicle shared by a plurality of users, the method being implemented by at least one processor and comprising the following steps: - registration of a digital identifier of each user of the plurality of users in a blockchain; - generation of a digital twin of the electric vehicle in the blockchain from initial data representative of the electric vehicle; - receiving second data representative of usage needs of the electric vehicle for each user of the plurality of users, the second data being associated with the digital identifier of each user in the blockchain; - determining third data representative of a distribution of use of the vehicle between the users of the plurality of users as a function of the second data, the third data comprising first information representative of time allocation of the electric vehicle to each user of the plurality of users, the first information being associated with the digital identifier of each user in the blockchain; - transmission of the first information to a mobile application implemented in a mobile communication device of each user via a wireless connection.

[0008] Such a method makes it possible to determine a schedule for using an electric vehicle by distributing the time of use of the electric vehicle to a plurality of users according to their needs. The distribution is determined securely and transparently for the users, benefiting from the advantages of the blockchain. Sharing an electric vehicle between several people makes it possible to spread the costs associated with the use of such an electric vehicle and to reduce the number of electric vehicles in circulation, which makes it possible to reduce the pollution associated with the circulation of vehicles as well as the need for materials to manufacture the vehicles.

[0009] According to a variant, the method further comprises the following steps: - generation, in the blockchain, of a digital twin of a charging station shared by the plurality of users from fourth data representative of the charging station; - determination of second information representative of allocation of time slots for recharging a battery of the electric vehicle via the charging station as a function of the second data and the fourth data, the second information being recorded in the blockchain, the determination of the third data being furthermore a function of the fourth data.

[0010] According to another variant, the method further comprises the following steps: - receipt of fifth data representative of a cost associated with the use of the electric vehicle and sixth data representative of a cost associated with use of the charging station; - registration of the fifth and sixth data in the blockchain; - determination of seventh data representative of a distribution of costs associated with the use of the electric vehicle and the charging station between the users of the plurality of users according to the third, fifth and sixth data, the seventh data comprising third information representative of allocation of a cost of use of the electric vehicle and the charging station to each user of the plurality of users, the third information being associated with the digital identifier of each user in the blockchain; and - transmission of third information to the mobile application implemented in each user's mobile communication device via the wireless connection.

[0011] According to another variant, the second data comprises for each user of the plurality: - temporal data representative of time slots of use of the electric vehicle; and / or - journey data representative of journeys to be made with the electric vehicle; and / or - occupant data representative of a number of occupants in the electric vehicle for each journey to be made with the electric vehicle.

[0012] According to an additional variant, the digital application is configured to implement a digital wallet.

[0013] According to a second aspect, the present invention relates to a device for controlling the use of an electric vehicle shared by a plurality of users, 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.

[0014] According to a third aspect, the present invention relates to a system for controlling the use of an electric vehicle shared by a plurality of users comprising a device as described above according to the second aspect of the present invention and at least one mobile communication device, the at least one mobile communication device being communicatively connected to the device as described above according to the second aspect of the present invention.

[0015] According to one variant, the system further comprises at least one remote device hosting a blockchain.

[0016] 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.

[0017] Such a computer program may use any programming language, and be in the form of source code, object code, or int code. an intermediate between source code and object code, such as in a partially compiled form, or in any other desirable form.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] Alternatively, the recording medium may be an integrated circuit in which the computer program is incorporated, the integrated circuit being adapted to perform or to be used in performing the method in question. Brief description of the figures

[0022] Other characteristics and advantages of the present invention will emerge from the description of the particular and non-limiting exemplary embodiments of the present invention below, with reference to the appended figures 1 to 3, in which:

[0024] [Fig.2] schematically illustrates a device configured to control the use of the electric vehicle of [Fig.l] shared by a plurality of users, according to a particular and non-limiting exemplary embodiment of the present invention;

[0025] [Fig.3] illustrates a flowchart of the different stages of a control process of the use of the electric vehicle of [Fig.l] shared by a plurality of users, according to a particular and non-limiting exemplary embodiment of the present invention. Description of the exemplary embodiments

[0026] A method, a device and a system for controlling the use of an electric vehicle shared by a plurality of users will now be described in the following with joint reference to Figures 1 to 3. The same elements are identified with the same reference signs throughout the description which will follow.

[0027] 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.

[0028] According to a particular and non-limiting example of embodiment of the present invention, the control of the use of an electric vehicle shared by several users, for example by several owners of the electric vehicle sharing its use, is for example implemented by a data processing device of the computer or server type, that is to say by one or more processors of the data processing device.

[0029] For this purpose, a digital identifier of each user of the plurality is entered in a blockchain, which is for example hosted in the device implementing the control of the use or in one or more other server-type devices connected in communication to the device implementing the control. A digital twin of the electric vehicle is generated in the blockchain from first data representative of the electric vehicle (for example the power of the electric motor, the capacity of the traction battery, the number of places available in the electric vehicle, etc.). Second data representative of the needs of each user in terms of mobility (current journeys, number of people to be transported, journey times, etc.) are received by the data processing device which associates the second data with the digital identifier of each user in the blockchain. Third data representative of a distribution of use of the vehicle between the users of the plurality of users are determined based on the second data, these third data comprising first information representative of time allocation of the electric vehicle to each user of the plurality of users. This first information is also associated with the digital identifier of the user to which it refers in the blockchain. Finally, the first information is transmitted to each user, more specifically to a mobile application executed by the mobile communication device (for example a smartphone) of the user concerned via a wireless connection.

[0030] [Fig.l] schematically illustrates a data communication environment for the use of an electric vehicle shared by a plurality of users, according to a particular and non-limiting exemplary embodiment of the present invention.

[0031] [Fig.l] also illustrates a system configured to control the use of a electric vehicle 10, according to a particular exemplary embodiment of the invention.

[0032] The communication environment 1 comprises a set of mobile communication devices of the smartphone type, a single mobile communication device 12 being represented in [Fig. 1].

[0033] Each mobile communication device in the set belongs to a different user of an electric vehicle 10 sharing the electric vehicle 10 with the other users. The users of the electric vehicle 10 thus form, for example, a set or a plurality of co-owners of the electric vehicle 10. These users live, for example, in the same building or in the same geographical area.

[0034] Each mobile communication device 12 is advantageously connected in communication with a system comprising for example one or more data processing devices 101, for example of the server type, and / or one or more remote devices 102 hosting one or more databases or registry base(s). This or these devices 101, 102 belong for example to the “cloud” 100 (or “cloud” in French). This or these devices 101, 102 constitute for example nodes of a network configured for hosting data or transactions of a blockchain formed of several blocks 110.

[0035] Each mobile communication device 13 is connected in wireless communication to the “cloud” 100, for example via a wireless link of the Wifi® type (according to IEEE 802.11 or one of the variations of IEEE 802.11) or via a wireless link of the LTE 4G or 5G cellular network type.

[0036] A wireless communication system allowing the exchange of data between the mobile communication device 12 and the “cloud” 100 corresponds for example to a communication system of the cellular network type, for example an LTE (Long-Term Evolution), LTE-Advanced, LTE 4G or 5G type network.

[0037] Each device 101, 102, 12 is thus configured to transmit data to the “cloud” 100 and to receive data from the “cloud” 100.

[0038] The communication environment 1 and the devices that compose it are configured for the implementation of a blockchain.

[0039] The blockchain, also called distributed ledger technology, is a digital tool for storing and communicating data without a central control body. The blockchain is configured to allow users of the blockchain (in this case each mobile communication device 12 and the data processing device(s) 101 and / or the remote device(s) 102), connected in a network, to share data directly, without an intermediary. A blockchain is a register or a large database of data which has the particularity of being shared simultaneously with all its users, all of whom are also holders of this register, and who also all have the capacity to enter data into it, according to specific rules set by a computer protocol secured by means of cryptography.

[0040] In a blockchain, the identification of each party (for example each mobile communication device 12 and / or the device(s) 101, 102) is carried out by a cryptographic method.

[0041] Each transaction is sent to a network (also called a storage “node”) of remote devices or calculations (for example computers or servers) located in different locations, for example in the “cloud” 100.

[0042] Each node hosts a copy of the database in which the history of the transactions carried out is recorded. All stakeholders (i.e., for example, each mobile communication device 12 and / or the device(s) 101, 102) can access it simultaneously.

[0043] The security system is based on a consensus mechanism of all nodes each time information or data is added. The data is decrypted and authenticated by data centers (also called "miners"). Each transaction thus validated is added to the database in the form of a block (of the blockchain) of encrypted data, a block being able to host several transactions.

[0044] Decentralized security management prevents transaction tampering. Each new block added to the blockchain is linked to the previous one (except for the first block in the chain) and a copy of this new block is transmitted to all nodes in the network. The integration of blocks is chronological, indelible and tamper-proof.

[0045] Blockchain technology is known to those skilled in the art. For example, it is described in a summary report from the French National Assembly dated December 2018 and entitled “Report of the joint information mission on blockchain and its uses: a sovereignty issue”.

[0046] Terms relating to blockchain have also been standardized, notably in the following standards: ISO 22739:2020, ISO / TR 23244:2020, ISO / TR 23455:2019 and ISO / TR 23576:2020.

[0047] A process for controlling the use of the electric vehicle 10 shared between a plurality of users based on the so-called blockchain technology 110 is implemented in the system of the communication environment 1.

[0048] Certain operations of the process are for example implemented by the data processing device 101. Other operations of the process are for example implemented by one or more devices 102 of the “cloud” 100 as well as by each mobile communication device 12.

[0049] In a first operation, a digital identifier of each user or co-owner of the electric vehicle 10 is entered in the blockchain 110. The digital identifier corresponds to a means of electronic identification of each user and makes it possible to make the link between the user, a natural person, in the real world and a virtual entity representing the user in the “cloud” 100, in particular in the blockchain 110.

[0050] The digital identifier of each user is for example generated from a mobile application installed and executed on the mobile communication device 12 belonging to the user concerned. The digital identifier allows each user to access the data recorded in the blockchain 110 in a secure manner, for example via the mobile application, after authentication on the basis of biometric data for example.

[0051] In a second operation of the process, a digital twin of the electric vehicle 10 is generated in the blockchain 110 from first data representative of the electric vehicle 10.

[0052] These first data are for example received from a computing device of the computer type or mobile communication device connected in communication to the “cloud” 100, these first data being for example entered by a user of the plurality of users via an HMI (Human-Machine Interface) of the computing device. According to a variant, these first data are obtained from a server of the “cloud” 100, for example from an identifier of the electric vehicle 10 (for example the vehicle identification number, called VIN (from the English “Vehicle identification Number”)).

[0053] The digital twin of the electric vehicle 10 corresponds to a model of the electric vehicle representing the characteristics of the electric vehicle 10. The digital twin evolves, for example, as modifications are made to the electric vehicle 10, for example linked to aging of the components of the electric vehicle 10 or linked to maintenance operations, such as the reduction in the capacity of the traction battery, changes of parts, organs or components, etc.

[0054] The generic twin is for example generated at the request of the data processing device 101.

[0055] The first data includes for example all or part of the following data, according to all possible combinations: - data representative of a type of electric vehicle, for example the make and / or model of the electric vehicle; and / or - data representative of the motorization of the electric vehicle; and / or - data representative of the characteristics of the vehicle's traction battery electric (capacity (in Ah), admissible charging power, battery type (e.g. Lithium-ion or other, etc.); and / or - data representative of autonomy (for example in km); and / or - data representative of the loading capacity (for example in kg); and / or - data representative of the number of occupants that can be transported.

[0056] In a third operation of the process, second data representative of usage needs of the electric vehicle are received for each user of the plurality of users.

[0057] These second data are for example received from the mobile communication device 12 of each user, for example from the mobile application.

[0058] These second data are for example provided by each user, for example through a questionnaire available online or via the mobile application.

[0059] The second data includes, for example, all or part of the following data, in all possible combinations: - data, called time data, representative of time slots for use of the electric vehicle, i.e. the times at which each user wishes to have the electric vehicle; and / or - data, called journey data, representative of journeys to be made with the electric vehicle, i.e. the starting and arrival points of each journey to be made, for example common or regularly repeated journeys, with for example the usual departure time for each journey; and / or - data, called occupant data, representative of a number of occupants in the electric vehicle for each journey to be made with the electric vehicle.

[0060] The second data are associated with the digital identifier of each user to whom they relate in the blockchain 110 to keep track between the expressed needs and the user who expressed their needs, which further allows any user to be able to know the needs of other users, if access to these data is authorized.

[0061] In a fourth operation of the process, third data representative of a distribution of use of the vehicle between the users of the plurality of users are determined based on the second data.

[0062] The third data are for example representative of a schedule of use of the electric vehicle 10 and comprise first information representative of time allocation of the electric vehicle 10 to each user of the plurality of users. The first information comprises information on the time slots allocated to each user, for example over a determined time interval (over 1, 2, 3, 6 or 12 months for example).

[0063] The device 101 thus determines according to the needs expressed by each of the user an optimal sharing of the use of the electric car 10, that is to say a sharing which best meets all the needs expressed.

[0064] Each user is thus allocated a set of time slots (day and time) based on the needs expressed and the needs expressed by other users. Certain identical time slots are for example allocated to several users, for example when these users have expressed similar needs (identical or similar journey at identical or similar times) allowing carpooling to be offered.

[0065] The first information is associated with the digital identifier of each user that it concerns in the blockchain 110 to keep track of the result of the distribution of the use of the electric vehicle and the user to whom slots for use of the electric vehicle 10 are allocated, which further allows any user to be able to know the slots allocated to other users, if access to this data is authorized.

[0066] According to an alternative embodiment, the second data are further determined as a function of the first data, for example as a function of the autonomy of the electric vehicle 10.

[0067] According to a particular embodiment, fourth data representative of a charging station or terminal 11 are received. These fourth data are for example received directly from the charging station 11 when the latter corresponds to a connected charging station, that is to say a charging station connected to the communication system of the communication environment 1. According to another example, these fourth data are received from a server of the “cloud” 100, for example a server maintained by the manufacturer or the supplier of the charging station 11, knowing an identification number of the charging station 11. According to yet another example, these fourth data are provided by a user, for example through an HMI implemented by a computer or a mobile communication device.

[0068] The fourth data are representative of a set of characteristics of the charging station 11, the fourth data comprising the following data, according to all possible combinations: - data representative of available charging power (for example expressed in kW); and / or - data representative of a recharge voltage; and / or - data representative of time slots allocated for recharging the electric vehicle 10.

[0069] The charging station 11 corresponds for example to a charging station belonging to the plurality of users sharing the electric vehicle 10, the plurality of users sharing the costs associated with the purchase, operation and maintenance of the charging station 11. According to a variant, the charging station 11 is shared between the plurality of users on the one hand and one or more other users on the other hand.

[0070] According to this particular embodiment, a digital twin of the charging station 11 is generated in the blockchain 110 from the fourth data to model the use of the charging station 11.

[0071] Second information representative of allocation of time slots for recharging the traction battery of the electric vehicle 10 via the charging station 11 is determined as a function of the second data and the fourth data, that is to say as a function of the needs in terms of journey expressed by the users (in particular the distances to be covered according to the environments crossed (city, road, motorway) and the availability of the charging station 11 for example. This second information is recorded in the blockchain 110 and associated with the digital twin of the charging station 11 in the blockchain 110.

[0072] According to this particular embodiment, the third data representative of the distribution of use of the vehicle between the users of the plurality of users are further determined as a function of this second information to provide periods of recharging of the traction battery as a function of the needs of the users and the slots available for the recharging station 11.

[0073] In a fifth operation of the process, the first information relating to each user is transmitted to a mobile application implemented in the mobile communication device 11 belonging to the user to whom these first data relate via a wireless connection.

[0074] In this way, each user is informed of the schedule for use of the electric vehicle concerning him or her, that is to say the time slots allocated to him or her for using the electric vehicle 10, possibly with the user(s) with whom he or she will share the electric vehicle 10 on one or more journeys (and associated time slots).

[0075] The data and information recorded in the blockchain 110 are “shareable” via the blockchain platform 110, for example a private or consortium blockchain, to be able to share this data in complete transparency, security and confidentiality in an immutable manner between all the actors in the system, i.e. the users sharing the use (and potentially the ownership) of the electric vehicle 10.

[0076] According to another particular embodiment, the process further comprises receiving fifth data representative of a cost associated with the use of the electric vehicle 10 and sixth data representative of a cost associated with a use of the charging station 11. These fifth and sixth data include, for example, the costs of acquisition, operation and / or maintenance of the electric vehicle 10 and the charging station 11 respectively.

[0077] The fifth data are recorded in the blockchain 110 and are associated with the digital twin of the electric vehicle 10. The sixth data are also recorded in the blockchain 110 and associated with the digital twin of the charging station 11.

[0078] Seventh data representative of a distribution of the costs associated with the use of the electric vehicle 10 and the charging station 11 between the users of the plurality of users are determined as a function of the third, fifth and sixth data to distribute the cost of use of the electric vehicle 10 and the charging station 11 as a function of the use made of the electric vehicle 10, according to the schedule established via the second data.

[0079] According to an alternative embodiment, the seventh data are determined based on eighth data representative of the actual use of the electric vehicle by each user. According to this alternative, each user identifies himself via his digital identifier when he begins a journey with the electric vehicle 10 (according to the determined schedule) and records the time at which he or she returns the electric vehicle 10 so that another user can use it according to the determined schedule. According to this alternative, the eighth data replaces the second data for the determination of the seventh data.

[0080] The seventh data comprises third information representative of allocation of a cost of use of the electric vehicle 10 and of the charging station 11 to each user of the plurality of users, the third information being associated with the digital identifier of each user in the block chain 110.

[0081] The third information is then transmitted to each user concerned to the mobile application of the mobile communication device 12 of the user concerned via the wireless connection between the “cloud” 100 and the mobile communication device 12 to inform each user of the cost associated with the use of the electric vehicle 10 according to the calculated distribution of use.

[0082] The payment or settlement of the cost associated with the use of the electric vehicle 10 by each user is for example carried out automatically by the mobile application of the user concerned, the mobile application implementing a digital wallet type function. The settlement information in accordance with the third information is for example recorded in the blockchain and associated with the digital identifier of the user having made the payment. This makes it possible in particular to share this data or information in complete transparency, security and confidentiality in an immutable manner between all actors / users of the system.

[0083] The determinations of the third data, seventh data, first information, second information and third information are for example implemented via an artificial intelligence algorithm, for example implemented in the form of a neural network.

[0084] Such a process thus makes it possible to control the use of the vehicle between all users, and optionally to control and manage the payments relating to the use of the electric vehicle 10 for all users.

[0085] [Fig. 2] schematically illustrates a device 2 configured for controlling the use of an electric vehicle shared by a plurality of users, for example the electric vehicle 10, according to a particular and non-limiting exemplary embodiment of the present invention. The device 2 corresponds for example to the data processing device 101. According to another exemplary embodiment, the device 2 corresponds to the mobile communication device 12 or to a node of the network hosting the data of the blockchain such as the device 102.

The device 2 can be produced in the form of electronic circuits or software (or computer) modules or even a combination of electronic circuits and software modules.

[0087] The device 2 comprises one (or more) processor(s) 20 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 2. The processor 20 may include integrated memory, an input / output interface, and various circuits known to those skilled in the art. The device 2 further comprises at least one memory 21 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.

[0088] 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 21.

[0089] According to various particular and non-limiting embodiments, the device 2 is coupled in communication with other similar devices or systems, for example for example via a communication bus or through dedicated input / output ports.

[0090] According to a particular and non-limiting exemplary embodiment, the device 2 comprises a block 22 of interface elements for communicating with external devices. The interface elements of the block 22 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 (LTE) “Long-Term Evolution” or in French “Long-Term Evolution”), LTE-Advanced (or in French 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”).

[0091] According to another particular and non-limiting exemplary embodiment, the device 2 comprises a communication interface 23 which makes it possible to establish communication with other devices (such as other computers of the on-board system) via a communication channel 230. The communication interface 23 corresponds for example to a transmitter configured to transmit and receive information and / or data via the communication channel 230. The communication interface 23 corresponds for example to a wired network of the Ethernet type (standardized by the ISO / IEC 802-3 standard).

[0092] According to a particular and non-limiting exemplary embodiment, the device 2 can provide output signals to one or more external devices, such as a display screen 240, touch-sensitive or not, one or more speakers 250 and / or other peripherals 260 (projection system) via output interfaces 24, 25 and 26 respectively. According to a variant, one or other of the external devices is integrated into the device 2.

[0093] [Fig. 3] illustrates a flowchart of the different steps of a method for controlling the use of an electric vehicle shared by a plurality of users, for example the electric vehicle 10, according to a particular and non-limiting exemplary embodiment of the present invention. The method is for example implemented by one or more processors of a data processing device such as the device 101 or the device 2 of [Fig. 2].

[0094] In a first step 31, a digital identifier of each user of the plurality of users is registered in a blockchain.

[0095] In a second step 32, a digital twin of the electric vehicle is generated in the blockchain from first data representative of the electric vehicle.

[0096] In a third step 33, second data representative of usage needs of the electric vehicle for each user of the plurality of users are received, the second data being associated with the digital identifier of each user in the blockchain.
