Description

P ROCE OF DEVELOPING A REFERENCE FIELD

US CONTEN.

The invention relates generally to the field of infotainment systems for vehicles, especially for motor vehicles. More particularly, the invention relates to a method for producing a multimedia content search filter to be proposed to an occupant of a vehicle via the infotainment system.

Currently, multimedia content providers offer such content to their users according to different criteria such as their habits and their viewing history. A list of multimedia content choices is established based on these different criteria and sent to the connected device used by the user for viewing. The connected device of the user is for example a mobile phone or a tablet, which allows a mobile view of the proposed multimedia content. However, this mobility is not taken into account by content providers to provide a list of multimedia content adapted to this mobility. It is therefore up to the user to search in the list which is proposed to him a possible adapted multimedia contents. In the situation where said user is an occupant of a motor vehicle, in particular a driver of such a motor vehicle, the attention and time required for such a search is incompatible with the requirements of safe driving.

There is therefore a need to provide an occupant of a vehicle a list of multimedia content most suited to the context of its mobility.

An object of the invention is to provide a method of developing a search filter that allows the establishment of a list of multimedia content most suitable for the context of a moving vehicle occupant .

For this purpose, it is provided, according to the invention, a method of developing a search filter for the establishment of a list of contents multimedia system for the attention of an occupant of a vehicle, the vehicle comprising an infotainment system comprising a wireless mobile communication module and a geolocation module such as a satellite navigation module, the method comprising the steps of: a) identifying the occupant and retrieving information associated with the occupant thus identified; b1) if the satellite navigation module is programmed with a destination, retrieving information relating to a remaining travel time to reach the destination thus programmed, estimated by the satellite navigation module; c) developing the search filter from the information thus retrieved; d) transmitting, via the wireless mobile communication module, the search filter thus produced to an aggregator of multimedia contents, the aggregator establishing a list of multimedia contents according to the search filter so transmitted

Thus, the fact of taking into account, in the development of the search filter, information concerning a remaining travel time to reach the destination of the occupant makes it possible to adapt the resulting list of multimedia contents to the context. of the movement made by the occupant, so to its mobility while respecting the information concerning said occupant.

Advantageously, but optionally, the method has at least one of the following additional technical characteristics:

in the step b1), information relating to the destination, contained in the satellite navigation module, is also retrieved and then used for the development of the search filter in step c);

the identification of the occupant is made from sensors present in the vehicle; the identification of the occupant is carried out on the basis of information concerning an occupant broadcasting device connected to the infotainment system;

the method further comprises a step b2), prior to step c), of recovering information relating to a driving mode of the vehicle, information used for the development of the search filter in step c) ;

the method further comprises a step b3), prior to step c), of recovering information relating to a physiological state of the occupant, information used for drawing up the search filter in step c) ; and,

if the occupant is identified as a driver of the vehicle and if the driving mode of the vehicle is a manual driving mode, the search filter is designed so that the list of multimedia contents to be broadcast includes only contents audio

the method comprises a step of displaying the list of contents established by the aggregator.

It is also provided according to the invention an infotainment system comprising a wireless mobile communication module and a satellite navigation module, acquisition means, processing by software instructions stored in a memory and control means required for the implementation of a production method having at least one of the preceding technical characteristics.

It is also provided according to the invention a vehicle comprising a previous infotainment system.

Other features and advantages of the invention will appear more clearly on reading the following detailed description of an embodiment of the invention given by way of non-limiting example and illustrated by the accompanying drawings, wherein :

FIG. 1 is a schematic view of a vehicle comprising an infotainment system according to the invention in which is placed implement the method of developing a search filter according to the invention.

Figure 1 shows, very schematically, a vehicle 1, automotive type. This vehicle 1 comprises an embedded infotainment system 10. The infotainment system 10 makes it possible to provide an occupant of said vehicle 1 with a set of information concerning the operation and the state of the vehicle 1, to program certain parameters of the vehicle 1, to allow the broadcasting of multimedia contents, etc. Here, the infotainment system 10 includes a wireless mobile communication module 20. The latter allows communication 21, for example through a wireless mobile telecommunication network known in itself, with a multimedia content aggregator. 3, located at a distance. The latter can be a dedicated server for this purpose. On the other hand, the infotainment system 10 comprises a satellite navigation module 30, such as a GPS navigation module ("Global Positioning System" according to the term Anglosaxon for global positioning system). The satellite navigation module 20 receives information 31 from positioning satellites 2 so as to constantly know the instantaneous position of the vehicle 1. From this information 31, the satellite navigation module estimates a travel time remaining to reach a destination that has been programmed by the occupant of the vehicle 1. On the other hand, the satellite navigation module 20 includes a storage memory with navigation maps and information relating to at least the destination programmed (addresses, region, country, points of interest, etc.).

The vehicle 1 is here equipped with an autonomous driving module 50 which allows autonomous operation of the vehicle does not require intervention of the driver of the vehicle. The infotainment system 1 is connected to this autonomous driving module 50 so as to be able to receive information relating to an autonomous driving mode: whether the vehicle 1 is in the manual driving mode or in the autonomous driving mode. . On the other hand, the vehicle 1 is here equipped with a set of sensors 60 that can provide information on the occupants of the vehicle 1. For example, the vehicle 1 comprises, in its cabin, cameras, such as a driver camera, presence sensors in the various seats of the vehicle 1. Information from this set of sensors 60 is accessible to the infotainment system 10 so as to allow identification of the occupant (s) of the vehicle 1 in order to retrieve information relating to the different occupants thus identified, information that can be stored in a database 40 accessible by the infotainment system 10. The information relating to the occupant thus identified concerns his preferences, his habits in terms of multimedia content, possibly information concerning accounts with suppliers of multimedia contents that would have the occupant thus identified.

The infotainment system 10 comprises at least one multimedia content diffuser 80. The multimedia content diffuser 80 may be an onboard audio system of the vehicle 1, a touch screen of the infotainment system, or broadcast screens located on the back of the seats for occupants sitting on rear seats.

The infotainment system 1 may be in connection with broadcast devices 70 connected, such as tablets or handheld devices (or smartphones according to the term Anglosaxon). The connection is made wirelessly, for example by "Wi-Fi" or "Bluetooth" protocol. This connection can be managed by the wireless mobile communication module 20. The broadcast devices 70 connected then serve as a multimedia content diffuser, through for example a dedicated application for this purpose previously installed on said broadcast devices 70 connected. On the other hand, the connected broadcast devices 70 are also used for the identification of the occupant to retrieve information relating thereto, information that can be recorded in the broadcast devices 70 connected, and this through the application dedicated.

Moreover, the infotainment system 10 comprises means of acquisition, processing by software instructions stored in a memory and control means required to implement a method of developing a search filter according to the invention that we will now describe in more detail.

The method of developing a search filter according to the invention is triggered either at the start of the infotainment system 10, or on a request from an occupant of the vehicle 1. Once triggered, the method of developing a search filter according to the invention performs a first step of identifying the occupant (s) present in the vehicle 1. For this, it uses the information from all the sensors present in the passenger compartment of the vehicle, 70 broadcast devices connected. Thus, the occupant considered is identified with its location in the vehicle 1 as a driver or passenger front or rear. From this identification, the method for producing a search filter according to the invention retrieves information relating to the occupant thus identified, in particular its preferences and habits as regards the multimedia contents, as well as possibly information concerning the different subscriptions that the occupant thus identified would have subscribed to suppliers of multimedia content. This information is stored either in the database 40 of the infotainment system 10 or in the broadcast device 70 connected to the occupant thus identified, or again at the level of the content aggregator 3.

In a second step, the method of developing a search filter according to the invention retrieves a set of information from the satellite navigation module 30, especially if the latter has been programmed with a destination. This set of information relates, in a first step, a remaining travel time to reach the programmed destination. This travel time is estimated directly by the satellite navigation module 20. The information on the remaining travel time will be integrated in the search filter by the method of developing a search filter according to the invention of so as to indicate to the content aggregator 3 to provide the occupant considered a choice of multimedia content whose duration does not exceed this time remaining course. In a second step, this set of information concerns information about the destination programmed in itself: addresses, region, country, points of interest, etc. which are provided in the navigation map recorded in the satellite navigation module 20. This information relating to the programmed destination will be integrated into the search filter by the method of developing a search filter according to the invention so as to indicate to the content aggregator 3 to provide the occupant considered a choice of multimedia content in relation to the environment of the programmed destination: tourist information, news about the surroundings of the programmed destination, own culture the intended destination, etc. .

If the vehicle 1 is equipped with an autonomous driving module 50, the method of developing a search filter according to the invention retrieves, in a subsidiary step, information on the current driving mode. This step is mainly triggered if the concerned occupant has been identified as the driver of the vehicle. If the information thus recovered is a manual driving mode, the method of developing a search filter according to the invention integrates into the search filter a criterion indicating to the content aggregator 3 to provide only one list of audio contents in line with the other criteria provided in the search filter. If, conversely, the information retrieved on the driving mode is an autonomous driving mode, the method of developing a search filter according to the invention includes in the search filter a criterion indicating to the content aggregator 3 to provide only a list of audio and / or video content in line with the other criteria provided in the search filter, while respecting the legislation and regulations regarding autonomous driving according to the location of the vehicle from the satellite navigation module 20.

In another subsidiary step, the method of developing a search filter according to the invention retrieves information on the physiological state of the occupant considered, particularly if the occupant considered has been identified as a driver of vehicle 1, as a state of fatigue. This information is then integrated into the search filter by the method of developing a search filter according to the invention so that the content aggregator 3 provides a list of multimedia contents adapted to this physiological state. In a third step, the method of developing a search filter according to the invention produces a search filter from the information that was retrieved during the previous steps. Each criterion of the search filter thus includes one or more information previously retrieved.

In a fourth step, the method of developing a search filter according to the invention transmits the search filter and elaborate content aggregator 3, using the wireless mobile communication module 20 The content aggregator 3, once the search filter has been received, establishes a list of choices of multimedia content meeting the criteria of the search filter. In the case where the occupant considered is subscribed to the content provider, the content aggregator 3 queries these content providers from the appropriate information associated with the occupant considered. This list of choices is then transmitted via the wireless mobile communication module 20 to the infotainment system 10. The latter then displays on the touch screen of the infotainment system 10, or on the screen of the infotainment system 10. content broadcaster 80 or broadcasting device 70 of the occupant considered, the list of choice thus transmitted. The occupant considered only has to choose a content in the list.

To illustrate the operation, we present a brief example. Imagine that a driver of a vehicle 1 is also a subscriber of a provider N of multimedia content. On arrival in a traffic jam, the autonomous driving mode is activated via the autonomous driving module 50. Then, the infotainment system 10 implements the process of developing a search filter according to the invention. 'invention. Upon receipt of the list of choices, the interface on the touch screen of the infotainment system 10 presents the driver with the continuation of the series of the supplier N that he has watched the day before, stating that he has only 29 min of autonomous driving and so he will not be able to finish it, but the interface, from the list of choices, also offers episodes of a new series that lasts 25 minutes. according to his preferences and his habits. In the same way, the interface proposes to him, always starting from the list this choice received, also to see emissions of a television group in "replay", programs of 25 min maximum, always according to his preferences and his habits. Various modifications and / or improvements obvious to those skilled in the art can be made to the various embodiments of the invention described in the present description without departing from the scope of the invention.
