[0002] In the automotive sector, it is known to manage the replenishment, also referred to as supply, of a vehicle's energy source of the fuel or electrical energy type by means of systems capable of informing a driver of the position and the rates specific to different refueling stations. Such systems are notably integrated or associated with navigation systems and conventionally use information from websites or applications, transmitted to remote servers. As a result, the availability, updating and / or accuracy of such data may be limited.

[0003] The invention falls within this context and aims to propose a method and a system for managing the replenishment of a vehicle's energy source allowing optimized exploitation and enrichment of the data available to a vehicle traveling on the road infrastructure.

[0004] The invention relates to a method for managing the replenishment of an energy source in an ego motor vehicle comprising: - the compilation of data external to the ego vehicle and to secondary vehicles, distinct from the ego vehicle and present in the road infrastructure, by a remote server and / or by a secondary vehicle connected to the road infrastructure, said external data coming from at least one online resource and at least one connected secondary vehicle; - reception, by the ego vehicle, of external data via a communication module; - the acquisition of internal data, specific to the ego vehicle, measured and / or estimated via a data acquisition module; - determining a resupply route, providing for at least one resupply of the energy source, based on external data and internal data.

[0005] Optionally, the method further comprises acquiring data relating to the external environment by the ego vehicle and transmitting, via the communication module, of said data to the remote server and / or to at least one connected secondary vehicle circulating in the road infrastructure.

[0006] For example, the external data relates to the price of supplying at least one energy source, to a duration or distance separating the ego vehicle from at least one supply station, to an availability of energy source, to a replenishment duration, to the road infrastructure, to weather conditions and / or to traffic.

[0007] In particular, the internal data relates to a pre-programmed initial route of the ego vehicle, to an energy source level, to a range of the ego vehicle, to a weight of the ego vehicle and / or to preventive maintenance parameters.

[0008] According to an exemplary embodiment, the internal data and the external data are each associated with a confidence index, corresponding to a degree of precision or reliability of said data, the determination of the resupply route taking into account such an index.

[0009] Optionally, the internal data and the external data are each associated with an importance index, corresponding to a degree of priority of said data predefined by the manufacturer or the driver, the determination of the resupply route taking into account such an index.

[0010] In particular, determining a resupply route includes generating a plurality of resupply routes and automatically selecting one of said routes based on at least one predefined criterion.

[0011] Optionally, the external data are updated in real time or at regular time intervals, the method comprising an update of the determination of a resupply route and / or the emission of an alert, for the attention of the driver of the ego vehicle, via a human-machine interface.

[0012] For example, the alert message is an audible and / or visual and / or haptic message to a driver of the ego vehicle communicated via an alert module.

[0013] The invention also relates to a system for managing the replenishment of an energy source in a motor vehicle, the system comprising hardware and / or software elements implementing the method according to the invention. The hardware elements comprise at least one data processing unit, a communication module and a data acquisition module internal and external to the vehicle.

[0014] The invention also extends to a motor vehicle equipped with a management system according to the invention.

[0015] The invention may also extend to a computer program product comprising program code instructions recorded on a computer-readable medium for implementing the steps of the method according to the invention. when said program runs on a computer. In other words, the invention may extend to a computer program product downloadable from a communications network and / or recorded on a data medium readable by a computer and / or executable by a computer comprising instructions which, when the program is executed by the computer, lead the latter to implement the method according to the invention.

[0016] The present invention also relates to a data recording medium, readable by a computer, on which is recorded a computer program comprising program code instructions for implementing the configuration method according to the invention, or a computer-readable recording medium comprising instructions which, when executed by a computer, cause the latter to implement the method as set out above.

[0017] Finally, the invention can be extended to a signal of a data medium, carrying the computer program product according to the invention.

[0018] Other details, characteristics and advantages will emerge more clearly on reading the detailed description given below, for informational and non-limiting purposes, in relation to the various exemplary embodiments illustrated in the following figures:

[0019] [Fig.l] [Fig.l] is a schematic view of an embodiment of a vehicle equipped with a system for managing the replenishment of an energy source of an ego motor vehicle

[0020] [Fig.2] [Fig.2] is a general flowchart of an example of execution of a replenishment management process.

[0021] [Fig.3] [Fig.3] is a schematic representation of an alternative execution example of the replenishment management method.

[0022] [Fig.4] [Fig.4] is a schematic representation of an example of data communication implemented between the ego vehicle, a secondary vehicle and a remote server.

[0023] [Fig.l] schematically illustrates an embodiment of a vehicle 1 equipped with an energy source replenishment management system according to the invention. The term “energy source” means fuel or electrical energy. The vehicle 1 can thus be a vehicle 1 with an electric, hybrid or thermal engine.

[0024] Throughout the description below, an ego vehicle will be referred to as a vehicle 1 equipped with a system 2 for managing the replenishment of an energy source and capable of implementing a method 100 for managing the supply according to the invention. The management system 2 may be included in a navigation system equipping the vehicle 1 or may communicate with such a navigation system. The ego vehicle 1 may be of any type, for example a private vehicle, a utility vehicle, a coach or bus. Also, the vehicle may or may not be an autonomous vehicle.

[0025] The ego vehicle is to be distinguished from a secondary vehicle 10 corresponding to a vehicle distinct from the ego vehicle circulating in the road infrastructure. It is understood that the terms “ego vehicle” and “secondary vehicle” are intended to distinguish distinct vehicles and not to establish a hierarchy of importance.

[0026] The management system 2 comprises hardware and / or software elements capable of implementing the method according to the invention. The hardware elements comprise at least one data processing unit 3, a communication module 4, in particular capable of communicating with a device, a target vehicle and / or a remote server 8, and an acquisition module 5 for data internal and external to the vehicle ego.

[0027] Optionally, the management system 2 further comprises: - a means of locating 6 the ego vehicle in a road infrastructure; - a driver alert module 7.

[0028] The processing unit 3 comprises one or more memory elements and a computer comprising hardware and software resources, in particular at least one processor, or microprocessor, cooperating with the memory element(s). The computer is capable of executing instructions for implementing a computer program and receiving data from various equipment equipping the vehicle 1 in question.

[0029] The communication module 4 is configured to transmit and receive a data stream by means of a low-frequency or high-frequency wireless link. This may, for example, be a wireless link based on “cellular” or “Wifi” technologies. In particular, said data may be sent directly to a connected secondary vehicle 10 traveling in the road infrastructure in order to implement inter-vehicle communication, also referred to as V2V communication for “vehicle to vehicle”. Additionally, the communication module 4 is capable of communicating with a remote server 8 capable of broadcasting data to secondary vehicles 10 and to the ego vehicle traveling in the road infrastructure in order to implement vehicle-server communication, or cloud, also referred to as V2C for “vehicle to cloud”.Optionally, data can be sent to a data management center 8a before being sent to the remote server 8. Optionally again, the communication module 4 is capable of communicating with connected road infrastructure elements in order to implement V2I communication for “vehicle to infrastructure”.

[0030] Generally speaking, the communication means is thus configured to communicate with any type of connected element so as to implement a “V2X” type connection.

[0031] The location means 6 is capable of locating the vehicle ego in the road infrastructure. It integrates, for example, a system for approximate location of the vehicle 1 and / or a high-definition map of the road infrastructure. In particular, the approximate location of the vehicle 1 may be provided by a GPS-type system, from the English acronym “Global Positioning System”. Alternatively or in addition, the location means 6 may be a location system embedded in the vehicle 1 which integrates the movements of the vehicle 1 permanently.

[0032] The acquisition module 5 comprises different measurement means capable of extracting data internal to the vehicle 1, for example relating to manufacturer or operating parameters of the vehicle 1, and / or capable of extracting data external to the vehicle ego relating to the environment external to the vehicle 1.

[0033] In particular, the acquisition module 5 comprises a plurality of measuring means. According to an exemplary embodiment, the location means 6 is a means for measuring a distance, a longitudinal speed, a duration and / or a position. The acquisition module 5 also comprises at least one sensor capable of measuring, in a non-limiting manner, at least one of a longitudinal speed, a range, a charge level and / or a weight of the ego vehicle. Optionally, the acquisition module 5 comprises several types of external data sensors, for example an image sensor, also referred to as an image capture means, capable of detecting information relating to the external environment, in particular to the prices of the energy source, the availability of said sources or any associated information available displayed in the external environment.For example, another type of sensor is capable of detecting, in particular continuously, the number of vehicles around the ego vehicle as well as their relative distances and speeds. The acquisition module 5 of the ego vehicle 1 is thus capable of collecting, in a non-limiting manner, information relating to the cost of replenishment, the availability of replenishment means, the congestion status of each replenishment station, the state of road traffic and / or road conditions, as further explained below.

[0034] Similarly, any secondary vehicle 10 can be equipped with a secondary acquisition module 11a, or any equivalent, similar to what has been explained above with reference to the acquisition module 5 specific to the management system 2 according to the invention.

[0035] The alert module 7 is capable of broadcasting a message and / or a signal in the form of transmission: - sound, for example by means of a loudspeaker, and / or - visual, for example by means of a screen-type display module, and / or - haptic, for example by means of an element capable of emitting vibrations included in the driver's seat or at least one control element of the ego vehicle such as the steering wheel.

[0036] Alternatively or in combination, such an alert may be disseminated via a human-machine interface.

[0037] An example of execution of the management method 100 for replenishing the vehicle 1 is described below with reference to FIGS. 2 to 4. The management method 100 can be considered as being a method of operating the management system 2 according to the invention or as a method of operating a vehicle 1 equipped with said system.

[0038] Generally, the method 100 for managing the replenishment of an energy source for an ego motor vehicle 1 comprises, firstly, a step E1 of compiling external data dt_ext to the ego vehicle and to secondary vehicles 10 present in the road infrastructure by a remote server 8 or by a connected secondary 10 of the road infrastructure. Here, the term "compilation" means the accumulation or collection of external data dt_ext, relating to the road infrastructure, by a defined means, namely here the server or at least one connected secondary vehicle 10 circulating in the road infrastructure.

[0039] In particular, said external data dt_ext come from at least one connected secondary vehicle 10, distinct from the vehicle 1 ego, in particular circulating near service stations as further explained below, and from at least one online resource Sx selected from a website, a database, an application or other. The different resources Sx considered are in particular, in a non-limiting manner, the supply stations, also referred to as service stations, connected or their sites, databases and applications, the price comparison sites for fuel or electrical energy. It is understood that the sources transmitting the data may extend to other installations.

[0040] In other words, the compilation step El comprises, in a first step, a sub-step Eli of acquisition of external data dt_ext by at least one secondary vehicle 10 and / or a sub-step E12 of information of the external data dt_ext by a third party on at least one online resource Sx. The data are notably obtained, in the case of the secondary vehicle 10, by means of a secondary acquisition module 11a specific to the secondary vehicle 10, or any equivalent, similar to what has been explained above with reference to the acquisition module 5 specific to the management system 2 according to the invention. In particular, the external data dt_ext are acquired by means of an image capture means equipping the secondary vehicle 10. The secondary vehicles 10 thus contribute to the collection and updating of the external data dt_ext.

[0041] The compilation step E1 then comprises a sub-step E13 of transmitting the external data dt_ext acquired or entered to the remote server 8 and / or to at least one secondary vehicle 10 ensuring the compilation E1 of data. The vehicle secondary 10 is equipped with a secondary communication module 12, capable of receiving and / or transmitting data in a manner similar to that which has been explained with reference to the communication module 4.

[0042] In this way, at least one online Sx resource and at least one secondary vehicle 10 transmit external data dt_ext, extracted or entered, to the remote server 8 or to a secondary vehicle 10 which compiles the data from the different sources.

[0043] Alternatively or additionally, the compilation step E1 is performed by at least one connected road infrastructure element and the above description applies mutatis mutandis.

[0044] The external data dt_ext relate in particular to the supply price of at least one energy, to a duration and / or distance separating the ego vehicle from at least one supply station, to an availability of energy source, to a replenishment duration, to the road infrastructure, to weather conditions and / or to traffic conditions. This data may also extend to the brand of the energy source or to the number of people at the service station.

[0045] The data relating to the replenishment price, the replenishment duration or availability are for example transmitted via websites or applications linked to at least one service station and / or via price comparison websites or applications. Also, these data can be transmitted by at least one connected secondary vehicle 10 implementing the sub-step Eli of external data acquisition dt_ext described above, circulating near a service station and capturing external data displayed or entered in the external environment.

[0046] The data relating to the road infrastructure may relate to road conditions, speed limits and / or the quality of the road surface. These data are, for example, transmitted via sites, the acquisition module 5 of the ego vehicle and / or a secondary acquisition module 11a of a secondary vehicle 10. For example, these data are transmitted via the location means 6 of the ego vehicle and / or equivalent equipment equipped in a secondary vehicle 10.

[0047] The same applies to data relating to road traffic, communicating in particular information relating to traffic jams or incidents in the road infrastructure, or to data relating to weather conditions in the road infrastructure.

[0048] The compilation El of external data dt_ext from secondary vehicles 10 advantageously allows more regular updating of the data and better reliability of said data. It also allows the availability of more data than simply using data entered on sites or applications.

[0049] The method then comprises a step E2 of receiving, by the vehicle 1 ego, the compiled external data dt_ext. The external data dt_ext are received via the communication module 4 then transmitted to the processing unit 3. Optionally, the external data dt_ext are recorded, at least temporarily, on the at least one memory element.

[0050] The method also comprises a step E3 of acquiring internal data dt_int, specific to the vehicle 1 ego, via the acquisition module 5. Such an acquisition corresponds to measurements, detections and / or estimations of data carried out before, simultaneously or subsequently to the reception E2 of external data dt_ext.

[0051] The internal data dt_int may relate to a pre-programmed initial route it_ini, a location, a power source level, a range, a vehicle weight and / or preventive maintenance parameters of the vehicle 1 ego.

[0052] For example, the location of the vehicle 1 ego and data relating to a pre-programmed initial route it_ini of the vehicle 1 are provided by the location means 6. Information relating to a starting point, a destination, a specific route and / or at least one intermediate stop can then be communicated to the processing unit.

[0053] The autonomy of the vehicle 1 and the quantity of available energy source are determined by means of at least one sensor of the acquisition module 5, such as a voltmeter or a fuel gauge. The remaining autonomy of the vehicle 1 is notably determined, in a conventional manner, from the quantity of available energy source and the real-time and forecast consumption of the vehicle 1.

[0054] The weight of the vehicle 1 once loaded is, for example, detected by means of acquisition module sensors 5 equipped at the level of at least one suspension of the vehicle 1 ego.

[0055] The preventive maintenance parameters of the engine are, for example, defined by a minimum energy source threshold below which the quantity of energy source must not fall.

[0056] Also, the internal data dt_int may relate to user preferences, entered via the human-machine interface or detected by learning. Said preferences relate in particular to the minimum energy source threshold, to one or more preferred energy source brands, to a preferred replenishment frequency, to limit tariffs or other.

[0057] The method then comprises a step E4 of determining at least one replenishment route it_app, providing at least one replenishment of energy source, as a function of the external data dt_ext and the internal data dt_int previously acquired or received.

[0058] The processing unit 3 can thus determine, on the basis of the most recent external data dt_ext and internal data, an optimal resupply route it_app. For example, the resupply route it_app can be determined in order to optimize an overall cost C_glob of the resupply. Here, the term "overall cost" means the consideration of the financial cost of the resupply, the importance and duration of a possibly necessary detour, for example in relation to the initial route it_ini, the modification or not of an initial route it_ini, a waiting and / or resupply time, involving a cost in time, and possible maintenance costs induced by premature aging of the engine, for example in the case of driving on fuel reserves.As further set forth below in the particular examples of execution of the method, the at least one it_app resupply route may also, optionally, be optimized based on weather and / or traffic information and / or user preferences.

[0059] According to a particular, optional exemplary execution, the determination E4 of the at least one replenishment route it_app is configured so as to be executed automatically according to at least one user preference or by learning in order to minimize the overall cost C_glob of the replenishment route it_app and / or of the replenishment by providing one or more partial replenishments. The replenishment route it_app thus determined provides for a first, partial replenishment at a first expensive station depending on the remaining autonomy of the vehicle 1 and limits said replenishment to what is necessary to reach a second, less expensive service station.

[0060] Various criteria can be integrated into the generation of the at least one resupply route it_app in order to define the most economical, shortest, most comfortable strategy in terms of weather or traffic conditions, depending on the availability times of the energy source, the crowds and / or the brand of the energy source.

[0061] Optionally, the determination E4 of at least one it_app resupply route comprises the generation E41 of a plurality of it_appx routes then the selection E42, automated or by the user, of an it_app resupply route from among those generated according to at least one of the aforementioned criteria.

[0062] Optionally but preferably, the method further comprises displaying the at least one it_app resupply route via the human-machine interface. In particular, said interface informs the user about the determined it_app resupply route and about a billing plan, summarizing the various financial costs estimated for said route.

[0063] Also, advantageously, the external data dt_ext and the internal data dt_int are optionally updated in real time or at regular time intervals. The method according to the invention is repeated so as to allow an update of the at least one replenishment route it_app.

[0064] Optionally, the method according to the invention comprises the emission of an alert to the driver of the vehicle 1 ego, via the human-machine interface, when the at least one updated resupply route it_app differs from a resupply route it_app proposed during a previous execution of the method according to the invention and / or when updated internal data dt_int or external data provided to the user differ from internal data dt_int or external data previously used to define the at least one resupply route it_app during a previous execution of the method.

[0065] The processing unit 3 is then able to record and compare at least one replenishment route it_app and all or part of the internal data dt_int and external data dt_ext to the vehicle 1 ego between different iterations of the method according to the invention. An alert message is then issued when a difference, in particular a difference having a significant effect on the at least one replenishment route it_app and / or on the billing plan, is detected during said comparison.

[0066] The alert message is in particular an audible and / or visual and / or haptic message emitted via the alert module 7.

[0067] The combination of internal data dt_int and external data dt_int as well as the use of data from secondary vehicles 10 circulating in the road infrastructure advantageously makes it possible to increase the quantity of data on the basis of which the management system 2 determines the at least one refueling route it_app and evaluates the relevance of stopping at different service stations considered for refueling.

[0068] The communication between one or more secondary vehicle(s) 10 and the vehicle 1 ego, directly or indirectly, via a remote server 8, ensures optimized availability of the information and more efficient and regular updating thereof. The external data dt_ext used are thus more recent and reliable. The management system 2 is thus able to take into account changes occurring during the journey of the vehicle 1 ego, such as changes in fare, crowds, availability or other. The system is then able to dynamically recalculate the at least one suggested it_app replenishment route and / or the billing plan in real time or at regular time intervals.

[0069] The management system 2 and the management method 100 according to the invention are optionally automated so as to execute the determination and selection of the replenishment route it_app to be applied without user intervention, either by favoring the solution presenting the lowest overall cost C_glob, or by favoring predefined criteria, entered beforehand, as detailed below. Such a principle advantageously makes it possible to reinforce driving safety by avoiding distracting the driver.

[0070] Optionally, the management method 100 according to the invention further comprises a step of acquiring data E5 relating to the external environment by the vehicle 1 ego. Such a step is executed in a similar manner to what has been described previously with reference to the secondary vehicles 10, so the above description applies mutatis mutandis to the vehicle 1 ego. Such an acquisition is carried out simultaneously or following the execution of the steps described previously. The vehicle 1 ego is thus able to participate in the compilation El of external data dt_ext and in the updating of said data by means of its acquisition module 5, which also benefits other vehicles present in the road infrastructure.

[0071] The external data dt_ext thus acquired are then transmitted E6, via the communication module 4, to the remote server 8 and / or to at least one secondary vehicle 10 connected present in the road infrastructure. As indicated previously, this data can be communicated directly to at least one secondary vehicle 10, via an inter-vehicle communication 1, or indirectly, via the remote server 8 and a V2C communication.

[0072] Optionally, the transmission E6 of the external data dt_ext to a secondary vehicle 10, in other words the reception E2 of said data by the secondary vehicle 10 in question, can be carried out conditionally. For example, the external data dt_ext are only transmitted to a secondary vehicle 10 if the latter requires a replenishment of energy source, that is to say if said secondary vehicle 10 has an energy source level less than or equal to a predefined threshold.

[0073] According to an optional exemplary execution, the different types of internal data dt_int and the external data dt_ext are each associated with a confidence index, corresponding to a degree of precision or reliability of said data. The determination of the resupply route it_app is then executed so as to take such an index into account. In particular, the confidence index is determined depending on the recency of the external data dt_ext, the type of acquisition implemented and / or a level of repetition, or confirmation, of said data. For example, a recently updated type of data, for example after acquisition by a secondary vehicle 10 or several secondary vehicles 10, a few minutes before the execution of the method according to the invention will be associated with a higher confidence index than the same type of data entered on an online resource Sx, such as a website, several days before the execution of said method. Similarly, the same price communicated by several distinct secondary vehicles 10 having recently circulated near a service station in question will present a better confidence index than a price entered by the website of said service station several days previously.

[0074] Optionally, the different types of internal data dt_int and the external data dt_ext are each associated with an importance index, corresponding to a degree of priority of said data. Such indices are predefined by the manufacturer and / or provided in advance by the driver or user, in particular via the human-machine interface in the form of execution preferences. The determination of the refueling route it_app is then executed so as to take such an index into account. According to a non-limiting example, the user can associate a greater importance index with the financial cost of refueling or with a defined brand of energy source than with the crowd or the refueling duration. The at least one refueling route it_app will then favor a service station offering lower prices over a service station with less crowding.

[0075] The invention thus proposes a method and system for managing the replenishment of a vehicle making it possible to optimize the overall cost of such replenishment in an autonomous, economical and reliable manner. The invention makes it possible to ensure appropriate availability and updating of the data necessary for such management.

[0076] The present invention cannot, however, be limited to the means and configurations described and illustrated here and it also extends to any equivalent means or configuration and to any technically operative combination of such means insofar as they ultimately fulfill the functionalities described and illustrated in the present document.
