A method, a device and a system for controlling an on-board system of a vehicle will now be described in the following with reference in conjunction with FIGS. 1 to 3. The same elements are identified with the same reference signs throughout. along the following description.

The control of an on-board system of a vehicle comprises the reception, via a wireless link, of first data representative of the use of the on-board system of the vehicle from a remote database. These first data are advantageously associated with the profile of a current user of the vehicle, these first data being for example obtained during a time period preceding the current instant of use of the vehicle, this time period corresponding for example to a learning period the user's habits in the use of the vehicle, more particularly in the use of the on-board system. Information representative of a current context for the vehicle is determined from second data obtained from at least one device on board the vehicle (for example one or more sensors of the vehicle and/or one or more control devices of integrated systems in the vehicle) and/or at least one mobile communication device (for example a smart telephone (“Smartphone”), which is linked in wireless communication with the vehicle. The vehicle, via of one or more on-board processors implementing, for example, a neural network, analyzes the information of the current context with regard to the first data received. This analysis makes it possible to determine how to control the on-board system by also relying on a level of autonomy associated with the control of the embedded system, this level of autonomy being granted by the user to the system.

The analysis of a current situation with regard to first data describing the use of the vehicle by a determined user coupled with a level of autonomy in the control of the on-board system makes it possible to determine, according to the situation, the habits of the user and the level of autonomy granted, if control of the on-board system by the user proves necessary or if the vehicle can control the on-board system completely autonomously without action by the user.

Such a method thus makes it possible to reduce the number of interactions between a user and an on-board system of the vehicle, which improves safety by reducing the time spent by the user controlling the on-board systems of the vehicle, as well as the user experience. which is less stressed by the vehicle's on-board systems.

The on-board system corresponds for example to a system implemented by one or more computers of the on-board system of the vehicle, which system implements a service and/or one or more functions, the on-board system corresponding for example to:

- a navigation system; and or

- a vehicle maintenance management system with prediction of future maintenance; and or

- an infotainment system for rendering multimedia, audio and/or video content; and or

- an air conditioning management system; and or

- a driving assistance system, known as the ADAS system (from the English "Advanced Driver-Assistance System" or in French "Advanced Driving Assistance System").

schematically illustrates a communication environment for a vehicle 10, according to a particular and non-limiting embodiment of the present invention.

There illustrates a communication environment 1 for a vehicle 10.

The vehicle 10 corresponds for example to a vehicle with a combustion engine, with electric motor(s) or else a hybrid vehicle with a combustion engine and one or more electric motors. The vehicle 10 thus corresponds for example to a land vehicle, for example an automobile, a truck, a bus, a motorcycle. Finally, the vehicle 10 corresponds to an autonomous vehicle or not, that is to say a vehicle circulating according to a determined level of autonomy or under the total supervision of the driver.

The vehicle 10 also advantageously embeds a communication system configured to communicate with one or more remote devices 101, 11 via an infrastructure of a wireless communication network. The remote device 101 advantageously corresponds to a device configured to process data, for example data stored in the memory of the remote device 101 and/or data received from the vehicle 10. The remote device 101 corresponds for example to a "cloud" server 100, the remote device 101 hosting for example in memory a database comprising a set of data representative of the preferences of a user of the vehicle 10, for example the owner or the driver of the vehicle 10.

The remote device 11 corresponds for example to a mobile communication device 11 such as a smart phone (“smartphone”) or a tablet. One or more mobile applications are advantageously installed on the mobile communication device 11, this or these mobile applications collecting for example data on the user and transmitting this data or part of it to the remote device 101 and/or of the vehicle 10.

The communication system of the vehicle 10 comprises for example one or more communication antennas connected to a telematics control unit, called TCU (from the English “Telematic Control Unit”), itself connected to one or more computers of the on-board system of the vehicle 10, for example an IVI computer (from the English “In-Vehicle Infotainment” or in French “Infodivertissement on-board”), which IVI computer controls the infotainment system of the vehicle 10 and the data to be rendered in the vehicle 10 (for example by display on a display screen embedded in the vehicle 10). The antenna(s), the TCU unit and the computer(s) form, for example, a multiplexed architecture for performing various services useful for the proper operation of the vehicle and for assisting the driver and/or the passengers of the vehicle in controlling the vehicle 10, for example by displaying regulatory speed information on a display device on board the vehicle 10. The computer(s) and the unit TCU communicate and exchange data with each other via one or more computer buses , for example a communication bus of the CAN data bus type (from the English “Controller Area Network” or in French “Réseau de Contrôleurs”), CAN FD (from the English “Controller Area Network Flexible Data-Rate” or in French “Flexible Data Rate Controller Network”), FlexRay (according to ISO 17458 standard) or Ethernet (according to ISO/IEC 802-3 standard).

The mobile communication infrastructure allowing wireless data communication between the vehicle 10 and the remote data processing device 101 and/or the mobile communication device 11 comprises, for example, several communication equipment items 110 of the relay antenna type (network cellular) or roadside unit, called UBR. In a mode of communication using such a network architecture, the data is for example transmitted by the vehicle 10 to the remote device 101 and/or to the mobile communication device 11 via a relay antenna 110 (the antenna 110 being for example connected to the " cloud” 100 via a wired connection).

The wireless communication system allowing the exchange of data between the vehicle 10 and the remote device 101 corresponds for example to:

- a V2I vehicle-to-infrastructure communication system, for example based on the 3GPP LTE-V or IEEE 802.11p standards of ITS G5; Or

a communication system of the cellular network type, for example a network of the LTE type (from the English “Long-Term Evolution” or in French “Long-term Evolution”), LTE-Advanced (or in French LTE-advanced) 4G or 5G LTE; Or

- A WiFi type communication system according to IEEE 802.11, for example according to IEEE 802.11n or IEEE 802.11ac.

According to a variant embodiment, the mobile communication device 11 and the vehicle exchange data according to a direct wireless connection, that is to say without going through the network infrastructure. The wireless connection is for example of the Bluetooth® or Wifi Direct® type.

According to a variant embodiment, the vehicle 10 also carries a satellite geolocation system configured to determine the current position of the vehicle 10, the vehicle 10 carrying for this purpose a receiver of a GPS type system (from the English " Global Positioning System” or in French “Global Positioning System”) or Galileo for example in communication with a computer of the on-board system of the vehicle 10.

The database 101 hosts or stores a first set of first data associated with the user, for example data corresponding to or describing a profile of use of the vehicle by this user, in particular and more particularly data corresponding to the use of one or more on-board systems of the vehicle 10, these data being associated with the user profile. The first data are for example a function of the on-board system with which they are associated.

For example concerning a navigation system of the vehicle 10, the first set of first data includes for example all or part of the following data, according to all possible combinations:

- data representative of the routes followed by the vehicle 10 and/or of the journeys made by the vehicle 10;

- data representative of the destinations entered into the navigation system of the vehicle 10 or of the mobile communication device 11;

- Time information associated with the journeys made, for example the date of the journey and/or the duration of the journey;

- kinematic data (for example the speed) associated with the journeys made;

- data representative of places and break times;

- data representative of a type of journey associated with each journey traveled with the vehicle, the type of journey comprising for example the types 'professional journey', 'personal journey', 'family journey', 'holiday journey', etc ;

- data representative of a distance traveled for each trip traveled with the vehicle 10;

- data representative of a type of road taken for each route traveled with the vehicle 10, the type of road comprising for example the types “motorway”, “fast lane”, “national road”, “city”, etc. ;

- any data describing the behavior of the user when using the vehicle 10.

Concerning an infotainment system of the vehicle 10, the first set of first data comprises for example all or part of the following data, according to all possible combinations:

- data representative of the radio channels listened to;

- data representative of the type of music listened to;

- data representative of the type of audio media watched;

- time information associated with the data of the first set;

- data representative of the rendering time of each media by the infotainment system.

Concerning an air conditioning management system of the vehicle 10, the first set of first data comprises for example all or part of the following data, according to all possible combinations:

- data representative of the temperature;

- representative ventilation data;

- data representative of air recycling;

- time information associated with the data of the first set;

- all data representative of air conditioning system adjustment parameters.

The first data associated with each on-board system of the vehicle 10 are for example crossed with each other to associate them with each other, according to relationships established between these data. For example, a particular setting of the air conditioning system is for example associated with a particular journey or a setting of the infotainment system is for example associated with a particular journey (for example listening to a specific radio channel during the morning journey to going to school or the office).

These first data are for example received from the vehicle 10 as each on-board system of the vehicle 10 targeted by the data collection is used.

According to a variant embodiment, the database also hosts or stores data representative of the preferences of the user, these data being for example collected from the mobile communication device 11 (corresponding for example to Internet searches), from applications social networks, applications for playing audio and/or video media, etc.

The first data collected is for example analyzed and processed by applying one or more automatic learning methods, also called machine learning methods, for example by relying on a network of neurons.

Such methods make it possible in particular to classify the data received and to determine the profile of use of the vehicle by this user. Such methods also make it possible to cross-reference the first data with each other to determine the existing correlations between these data and to establish the habits of use and the settings of these on-board systems, according to a context of use of the vehicle 10 and/or or these embedded systems.

The context includes for example the time of day when an on-board system is used, the state of the environment of the vehicle (for example the temperature, the weather conditions, the state of the traffic with for example the presence or not of traffic jams, the presence or absence of accidents, etc.).

A process for checking each onboard system of the vehicle 10 is advantageously implemented by the vehicle 10 (that is to say by one or more devices onboard the vehicle 10, for example one or more computers) and/or by a system comprising the vehicle 10 and one or more remote devices such as the device 101 and/or the mobile communication device 11 connected in communications to the vehicle 10 via one or more wireless connections.

The following operations are described for an embedded system for clarity. Of course, the same operations apply for each on-board system of the vehicle 10 targeted by the process.

In a first operation, the vehicle 10 receives the first data representative of the use and/or configuration of the on-board system of the vehicle 10 by the user. These first data are advantageously received from a remote database stored in a remote device 101.

The first data is received from the remote device 101, for example after transmission of a request by the vehicle 10 to the remote device 101, for example when the vehicle 10 is started or when the on-board system is implemented. According to a variant embodiment, the first data is received automatically, without a request, for example at regular intervals or each time the vehicle 10 is started, for example, these first data being for example stored in the memory of the computer controlling the on-board system.

The first data stored in the remote database are advantageously transmitted by the vehicle 10 to the remote device as the on-board system is used. The first data is for example received from the computer controlling the on-board system via a data bus connecting this computer to the computer or computers in charge of the process, this or these computers then transmitting the first data received to the remote device 101 via a controlled wireless connection by the TCU of the vehicle's on-board system 10.

These first data transmitted to the remote device 101 are for example associated with context data or information and/or the state of the vehicle 10 at the time of obtaining these first data. The context data is for example obtained from one or more sensors on board the vehicle 10 and transmitted by the vehicle 10 to the remote device 101. According to another example, the context data or information is transmitted to the remote device by one or more other devices, for example the mobile communication device 11 and/or one or more “cloud” servers 100. This data or context information concerns, for example, meteorological data obtained from a server receiving current meteorological information, road traffic received from an infrastructure server in charge of monitoring the road network, route data received from a mobile application executed on the mobile communication device 11, data representative of the received from the mobile communication device 11, etc.

In a second operation, the vehicle 10 determines one or more pieces of information representative of the current context of the vehicle 10 from second data obtained or received from one or more devices on board the vehicle 10 (for example one or more sensors and/or a or several computers in charge of controlling organs or components ensuring the operation of the vehicle 10) and/or received from the mobile communication device 11.

Information describing the current context includes, for example:

- one or more pieces of information representative of a current position of the vehicle 10 obtained for example from an on-board geolocation device (GPS receiver for example) and/or obtained from the mobile communication device 11 when the latter is on board the vehicle 10; and or

- one or more pieces of information representing a journey, a destination or an itinerary of the vehicle 10, this information being obtained from the navigation system on board the vehicle 10 and/or from a mobile navigation application executed on the mobile communication device 11; and or

- one or more time information, for example the current date and time for example obtained from a vehicle clock, the estimated time of arrival at destination, the estimated duration of a journey, etc. ; and or

- one or more information representative of the environment (for example the temperature, the weather conditions, the road traffic, the presence of vehicles or other objects in the immediate environment of the vehicle 10) of the vehicle 10 for example obtained from sensors embedded in the vehicle or remote devices connected in wireless communication with the vehicle 10; and or

- one or more information representative of the current state of the vehicle obtained for example from sensors or computers on board the vehicle 10 (for example mileage of the vehicle, level of wear of certain components such as the brakes, tire pressure, level of oil, etc.)

- one or more information representative of a timetable (date, time and place of an appointment, dates and place of planned holidays, etc.) for example obtained from a diary of the mobile communication device 11.

In a third operation, the vehicle 10 analyzes the current context information of the vehicle obtained in the second operation in relation to the first data received in the first operation. The analysis is for example implemented by a neural network implemented by one or more computers of the on-board system of the vehicle 10.

The analysis includes for example a crossing between the context information and the first data relating to the use of the vehicle 10.

Such a crossing thus makes it possible to determine what configuration or what use is usually made of the on-board system of the vehicle 10 in the context corresponding to the current context of the vehicle 10, knowing the habits of use of the on-board system of the vehicles described by the first data stored in the remote database.

For example, if the current context indicates that the user of vehicle 10 starts his day, that the date corresponds to a working day of the week, the analysis determines that in this context the user accompanies his children to school before to go to his place of work.

The first data corresponding to this context make it possible, for example, to identify a first destination (the school) followed by a second destination (the workplace) (therefore a setting of the on-board navigation system), a usual setting of the air conditioning (setpoint temperature for example depending on the outside temperature) and/or the radio usually listened to by the user on the first trip to school then that usually listened to by the user on the trip between school and his workplace.

If no correlation between the current context and the first stored data is established following the analysis, the process ends with the third operation.

In a fourth operation, depending on the result of the analysis implemented in the third operation, and depending on autonomy information associated with the on-board system (received for example from the remote device 101 and stored with the user profile in the database), the vehicle 10 determines:

- if the setting corresponding to the result of the analysis is automatically applied to the on-board system without asking the user for validation;

- if the configuration corresponding to the result of the analysis is applied to the embedded system after requesting validation from the user, for example by displaying a question (for example "Please validate the destination 'school'") and associated graphic objects (for example “YES”, “NO”, “CANCEL” buttons), and/or by rendering by voice synthesis of the question and interpretation of the voice response pronounced by the user;

- if the setting corresponding to the result of the analysis is neither applied automatically nor offered to the user, the embedded system awaiting the entry of the setting or control commands from the user before implementing the service or the function associated with the embedded system

The rendering of the validation request is advantageously generated by the IVI computer in charge of the vehicle's infotainment system.

The rendering corresponds for example to the rendering of a voice message by one or more loudspeakers of the vehicle 10 and/or by the loudspeaker of the mobile communication device 11 when the latter is on board the vehicle 10 and connected to the latter. .

According to another example, the rendering corresponds to a display of graphic content on a screen on board the vehicle and/or on the screen of the mobile communication device 11 when the latter is on board the vehicle 10 and connected to the latter. . According to this example, a text explaining the configuration proposed and determined from the analysis is displayed on a screen via a man-machine interface (known as an HMI), for example the HMI managed by the IVI computer.

The level of autonomy includes for example 3 levels or 3 modes, namely:

- autonomous mode, according to which the user delegates the configuration of the on-board system to the computer(s) of the vehicle 10 in charge of the process, that is to say that the vehicle 10 determines in complete autonomy (without user action ) to apply the configuration corresponding to the result of the analysis;

- semi-supervised mode, in which user validation is required before applying the settings corresponding to the analysis result;

- supervised mode, according to which the user decides on the configuration of the on-board system without suggestion of configuration by the vehicle.

The level of autonomy is advantageously determined by a machine learning method. Such learning is for example implemented by a neural network, implemented by:

- the vehicle 10 (that is to say the computer(s) of the vehicle 10 in charge of the process, the learning result being transmitted to the remote device 101 by the vehicle 10 for storage in the user profile;

- the remote device, depending on the answers provided by the user to the requests/questions sent to the user via a man-machine interface implemented in the vehicle 10, the answers being transmitted by the vehicle 10 to the remote device 101.

The learning of the level of autonomy is for example obtained according to the answers of the user to the questions/requests relating to the application of the parameter setting resulting from the analysis of the third operation.

For example, if the user systematically validates the proposal to listen to radio "XXX" ("XXX" corresponding for example to the commercial name of the radio) on the route leading to his place of work corresponding to the analysis result, then the level of autonomy associated with the infotainment system in charge of the radio corresponds to the autonomous mode. According to a variant embodiment, the validation of the "autonomous mode" to the infotainment system is required by the rendering of a request asking the user if he validates this setting of the level of autonomy associated with the infotainment system, for example for this particular journey or globally.

However, if the user decides not to validate this setting of the level of autonomy or if the user does not systematically validate the proposal to listen to the "XXX" radio on the journey leading to his place of work, then the level range associated with the infotainment system is set to "semi-supervised mode".

Such a process thus makes it possible to delegate a level of autonomy to each on-board system of the vehicle 10 after learning the habits of use of these on-board systems by the user.

When the user delegates to the system the validation of the configuration of one or more on-board systems in the vehicle 10, the configuration of these on-board systems is done automatically without action from the user, according to the habits of the user learned by the system vis-à-vis the use that has been made of these on-board systems. This reduces the necessary interactions between these on-board systems in the vehicle 10 via the associated HMI(s), allowing the user to focus on the road.

For example several sets of raw data are stored in the remote database for several user profiles, with a different set per user profile. The set of first data associated with a particular user profile is for example transmitted to the vehicle 10 after identification of the user of the vehicle 10.

In a second step 32, the vehicle (or one or more computers of the vehicle) determines information representative of a current context for the vehicle from second data obtained from at least one device on board the vehicle and/or from at least one mobile communication device connected in wireless communication with the vehicle 10.

In a third step 33, the vehicle (or one or more vehicle computers) analyzes the information determined in the second step 32 in relation to the first data received in the first step 31.

In a fourth step 34, the vehicle (or one or more computers of the vehicle) controls the on-board system according to a result of the analysis and a level of autonomy associated with the control of the on-board system.
