According to the preferred embodiment, the system 100 is on board a land motor vehicle, for example a motor vehicle, and is distributed among one or more on-board computers and / or computers. Alternatively, according to other embodiments, certain elements of the system 100 are partly hosted on board a land motor vehicle, on one or more computers / computers, while other elements are distributed on one or more servers. distant. It is therefore possible, for example, to envisage certain embodiments in which, the information processing unit 101 and / or the data storage medium 102 are, in part or totally, deported to a remote server.

For certain tasks relating to certain stages of the method according to the invention described below, the system 100 interacts, preferably by means of its input and output interface 103, with a driving aid device. 105 of the vehicle which comprises a plurality of detection devices (not shown), for example a radiation detection device, a laser remote sensing device, an ultrasonic sensor and / or a camera. Conventionally, the driving aid apparatus 105 also comprises one or more computers / calculators which, according to established roles and according to signals / data generated by the detection devices, control the operation of certain vehicle components to provide various driving assistance functionalities, in particular autonomous driving assistance functionalities (eg as4 emergency braking assistance, obstacle avoidance, lane departure).

For other tasks relating to other steps of the method according to the invention described below, the system 100 interacts, preferably through its input and output interface 103, with a first man-machine interface 106 of the vehicle which comprises at least one screen, preferably a touch screen, the touch interaction functionalities of which are managed by a management device (not shown) forming an integral part of the screen and / or of the second man-machine interface 106 Conventionally, the management apparatus is capable of generating data / signals as a function of perceived interactions.

For other tasks relating to other stages of the method according to the invention described below, the system 100 interacts, preferably through its input and output interface 103, with a second man-machine interface 107 of the vehicle which, preferably, comprises at least one electroacoustic transducer (not shown), ie a microphone, at least one loudspeaker (not shown) and / or a speech processing apparatus (not shown). Conventionally, the electroacoustic transducer converts a perceived acoustic signal into an electrical signal that the speech processing equipment uses to generate data and / or signals.

For other tasks relating to other stages of the method according to the invention described below, the system 100 interacts, preferably through its input and output interface 103, with a navigation system 108 of the vehicle which, conventionally, provides navigation functionality by interacting with a satellite positioning system.

Finally, for other tasks relating to other steps of the method according to the invention described below, the system 100 interacts, preferably through its input and output interface 103, with a transmitter of radio frequency signals from vehicle 109, which comprises at least one antenna (not shown) and conventional communication equipment (not shown) allowing communication by radio frequency signals with a remote entity, for example a computer server.

All the elements described above contribute to allow the system 100 to implement a method of constituting a set of informative data, as described below.

As illustrated in FIG. 2, according to a step 201, the system 100 detects the deactivation of a driving aid functionality managed by the driving aid apparatus 105 having been previously activated. To do this, the system 100 provides control over the activation and deactivation of the driving aid functionalities provided by the driving aid switchgear 105 by regularly transmitting requests to the driving aid switchgear. the pipe 105 to which the latter responds by transmitting data which characterizes an operating state (activated vs. deactivated) relating to each of the driving assistance functionalities which it provides. Alternatively, the driving aid apparatus 105 transmits by itself data which characterize an operating state relating to each of the driving aid functionalities which it provides, on a regular basis and / or during changes. status (activated -> deactivated & deactivated -> activated). By these mechanisms, the system 100 is therefore able to detect the activation and deactivation of one (or more) driving aid functionality (s) managed by the driving aid apparatus 105 In addition, advantageously, the system 100 uses these interaction protocols with the driving aid apparatus 105 to determine, with respect to each of the driving aid functionalities provided by the driving aid switchgear 105, when deactivating a driving aid functionality, an instant at which the driving aid functionality concerned has been activated beforehand. Preferably, this information is recorded on the data storage medium 102. Then, according to another step 202, following the deactivation of the driving assistance functionality detected during the previous step 201, the system 100 controls the broadcasting of a visual indication on the screen of the first man-machine interface 106 and / or the broadcasting of an audible message by means of the loudspeaker of the second man-machine interface 107. do this, the system instructs the first man-machine interface 106 and / or the second man-machine interface 107 by transmitting data which is interpreted as control commands and executed by one or the other man-machine interface 106, 107 to implement the dissemination of the visual indication and / or the audio message. Advantageously, the visual indication and / or the audible message invites (s) the driver to submit an assessment relating to a feeling related to the episode of use of the driving aid functionality which has occurred. occurred between the activation of the latter and its deactivation detected during the previous step 201.

Then, in another step 203, the system 100 determines, using the information processing unit 101 and the input and output interface 103, appreciation data by exploiting a signal generated by the electroacoustic transducer of the second man-machine interface 107 and / or of the data generated by the management equipment of the first man-machine interface 106. In fact, as mentioned above, the system controlled during the step previous 202 the broadcast of a visual indication and / or an audible message. This new step 203 therefore makes it possible to collect the appreciation of the user, whether it is submitted by voice or by means of an interaction with the touch screen carried out by the user. To do this, the system 100 receives a signal directly generated by the electroacoustic transducer and / or data generated by the speech processing equipment of the second man-machine interface 107 and / or data generated by the speech processing equipment. management of a touch screen interaction functionality (or of the first human-machine interface 106). On the basis of these elements, the system 100 is able to determine appreciation data, comprising for example a numerical parameter, which correspond to an appreciation relating to the feeling of the user with respect to the episode d use of the driving assistance functionality that the driver submitted following the implementation of the previous step of broadcasting a visual indication and / or an audible message. The appreciation of the user's feeling was therefore perceived by the electroacoustic transducer when it was subjected vocally and / or by the apparatus for managing a tactile interaction of the screen (or of the first human interface -machine 106) when it has been submitted via the touch screen. The system 100 has therefore received, via the input and output interface 103, data which allow it to generate appreciation data. Alternatively, it can however be envisaged that the appreciation data are generated by the apparatus for managing a touchscreen interaction functionality of the screen (or of the first human-machine interface 106) or, respectively, by the speech processing equipment of the second man-machine interface 107.

Then, in another step 204, the system 100 determines, using the information processing unit 101, the data storage medium 102 and / or the input and output interface 103, data of location corresponding to a road segment traveled between the activation and deactivation of the driving assistance functionality. To do this, the system 100 determines an instant at which the driving assistance functionality has been activated beforehand. Alternatively, the system 100 retrieves this information from the data storage medium 102 when it has been previously determined during step 201. The system 100 then uses this information to interact, via the interface d entry and exit 103, with the navigation system 108 in order to obtain location data, for example geographical coordinates, relating to the road segment which has been traveled between activation and deactivation of the assistance function to the driving. In return, the navigation system 108 supplies the location data to the system 100. Alternatively, the navigation system 108 supplies the system 100 with data which it processes to determine the location data.

Then, in another step 205, the system 100 determines the informative data on the basis of the appreciation data and the location data. To do this, the system 100 uses a predetermined method to aggregate the appreciation data and the location data determined during the previous steps. In other words, the informative data therefore consists of a combination of the appreciation data and the location data. Thus, during this step, the system 100 establishes a link between a segment of the road traveled using the driving aid functionality and an appreciation of the user with respect to this episode of use of the functionality of driving assistance. Alternatively, or cumulatively, the system 100 also determines identifiers which thus make it possible to link the informative data to a particular user.

Finally, during a final step 206, the system 100 interacts, using the processor 101 and the input and output interface 103, with the transmitter 109 to transmit the informative data to a remote entity, by example a remote computer server, one of the roles of which is to provide users of a community with a visualization interface making it possible to visualize this informative data, for example in the form of interactive road maps. Community users can obviously interact with the server using any conventional communication device (eg smartphone, tablet, desktop computer, personal assistant, etc.) to view informative data, preferably with regard to the routes they have planned and submit their parameters using an input interface. Advantageously, the input interface can also be used by a user to modify informative data of which he is the origin. Indeed, when the informative data is linked to user identifiers, it can be envisaged that particular rights are conferred on the users so that each user of the community identified according to a pre-established identification protocol can modify the informative data which they are linked.

Therefore, under the method and the system according to the invention described above, the functional bricks are provided to allow a user to submit in a simple manner an assessment relating to a feeling related to an episode of use of driver assistance features, for example an episode of using driver assistance features provided by a land motor vehicle. In addition, the method and system according to the invention contribute to allow the creation of a collaborative platform for the sharing of knowledge with regard to assistance functions for driving land motor vehicles.

The invention is not limited to the embodiments described above, presented only by way of examples, but extends to other embodiments, in particular those formed by combining certain characteristics described in connection with certain embodiments with other characteristics described in connection with other embodiments which are within the reach of those skilled in the art.
