Description

1, The present invention relates to a system

  multimedia for motor vehicle.

  It relates more particularly to a multimedia system making it possible to deliver to passengers of a vehicle general multimedia information as well as information characteristic of places that the vehicle is passing through at the same time as it allows them to follow on a screen, the progress of the vehicle on a map representing the area of

  territory crossed by the vehicle.

  In known multimedia systems of this type, the geographic map representative of the geographic area traversed by the vehicle is provided by a database of a data processing system. A navigation center comprising in particular a satellite radionavigation system, of the type for example of that known under the English abbreviation GPS of "Global Positioning System", determines at all times the

  geographic coordinates of the vehicle.

  The characteristic information of the places crossed is also stored in the vehicle database, and is read as the vehicle progresses on its route. The renewal or updating of information in the database is carried out using floppy disks or DVD discs or CD ROMs inserted in an appropriate drive of the data processing system, this renewal or this updating. d our data takes place according to a chosen route which must be followed by the vehicle. Such systems are generally suitable for broadcasting animations in tourist vehicles, such as coaches, boats or aircraft. The animations to be broadcast are prepared in advance by the organization organizing the trip and they are broadcast under the control of the information processing system according to the places crossed by the vehicle and possibly according to the date and time. time in which the vehicle is taken to a place in the air, at the same time as the information system displayed on the car displayed on the display screen, the location of the corresponding place. However, such a system is no longer suitable when the vehicle is to be changed. They are often changed in the same route day. This is the case, for example, of the Laxis who evolve in a big city, because it is no longer possible to predict in advance the routes that the vehicle will follow in the same day and even less to carry out recharges. updates of the database to the means of recording support each time a new

  run on a new iLindraire doiL ALre effecLude.

  Furthermore, these systems which are mainly intended for passengers in the vehicle are unsuitable for exterior broadcasting on electronic panels visible in broad daylight or at night, as well as to the driver's concerns of the vehicle, which would also like to have information. concerning the illiterate that it is in the process of following without being disliked by the

  passenger specific information.

  THE BALL OF THE INVENTION IS TO OVERCOME THE RISK DISADVANTRIES IN PROOSAL AN INNOVATIVE SYGL @ ME AND ALLOWABLE ANIMAL ULLIMDIA FOR THE PASSENGERS OF THE REAR SEATS OF THE VEHICLE WITH AN EFFECTIVE REGION OF THE ADVERTISING SPACES THROUGH THEIR DISSEMINATION

  FUNCTION OF VEHICLE MAP POSITIONING.

  To this end, the object of the invention is to provide a multi-vehicle system for the Nox car in Laxi, characterized by the fact that it includes in the vehicle: - a central unit for the actual couple: - A data base comprising the documents mulLimdia difEuGer, navigaLion data, inL @ r8LG point characteristics, electronic mail required by vehicle passengers, passenger profile data as well as statistical distribution data intended for advertisers, - a VEHICLE LOCATION SYSTEM - A display system for passengers on the back of the vehicle allowing information contained in the vehicle database to be disseminated according to the geographic coordinates of the vehicle provided by the SYGL @ location locator, - a display and input system intended for the driver and allowing him to guide him in his races, - a display gyGtAme visible from our day and night from the outside r of the vehicle,

  - a Gon neutralization system coming from high-

  rear speakers placed above the driver's head so as not to interfere with his driving, - and a digital radio communication system communicating with at least one outside station allowing the vehicle to: - Automatically send the driver requests for shopping, - from LansmeLLre to the outside station the vehicle location coordinates provided by the location gyGtAme, and at any time, automatically loading and updating, by the outside station, the information contained in the database VEHICLE DISPLAYED ON THE DISPLAY GYGtAme

  function of vehicle location coordinates.

  The multimedia system according to the invention makes it possible to obtain a vehicle localization accuracy of the order of 10 meters thanks to an interface grouping together in the localization system an OPS satellite positioning device, an odometer, and a gyroGcope. It also offers an automatic and / or interactive interface for the positioning of points of interest, with management of lists of points of interest by layers comprising activation / deactivation mechanisms and modification of the layer assignment. Itineraries are calculated using a "man machine" interface which allows the driver to select the destination of the vehicle. A display by way of the roadmap and a voice reminder of the actions to be taken allows the changer to be guided. A re-calaul at the end of the route is performed each time a proposed route is not followed. The route is refined in real time, every minute for example, based on traffic information. The dynamic position of the taxi appears on a fixed map of variable size by zoom effect or on an animated map depending on the movements of the taxi and the route followed. The system may also include game consoles for overlaying images with other system functionality. Mobile phones or PDAs can also be connected to the system by infrared or Bluetooth type links so as to receive information or available programs provided by the system itself or by advertisers or partners with the possibility of interaction. on the on-board display. According to another characteristic of the invention, the system comprises a plurality of individual locator boxes allowing customers to enter into communication with the central management station via a mobile telephone of cellular radio communication network, each box locator comprising a radio navigation satellite module and at least one memory for storing the identity of the calling client and means for transmitting to the central management station via the mobile telephone the geographical coordinates of the place where the caller is located as well as his identification, and in that the central management station has means for identifying a free taxi closest to the place where the calling customer is located and for transmitting the coordinates of the calling customer to him. The main advantage of the system according to the invention is that it provides new services to vehicle users linked to new information and communication technologies. It allows in particular to arrange vehicles in the manner of a mobile office offering users continuity of their workplace. They can indeed communicate at will on the Internet, with the added pleasure of being able to be informed at any time about the characteristics of the places they are crossing. On the other hand, the coupling of the location system to the digital radio communication system has the advantage for taxis that it makes it possible to collect in a dispatching center the location information of the vehicle to assign it to a passenger, possibly the closer to the place where the taxi is to optimize its rallying route. It also makes it possible to usefully guide the driver to his destination thanks to a map which scrolls on his touch screen and in the event of aggression and an alarm triggered by the driver to communicate the position of the vehicle to

police services.

  As other advantages, the system according to the invention makes it possible to conserve the management of the traces of advertisements of an advertising or other order, of the journeys of the users on the proposed places, of responses to the on-board questionnaires, even of the feedback of special information such as a pollution mapping thanks to on-board sensors

For advertising purposes, an advanced display system available on the law of the vehicle, not shown, is visible from outside the vehicle, which is also connected to the data bus 4, in order to be able to broadcast NEWLY ANNOUNCED DIFFERENCES FROM THE ONE THAT APPEARS ON THE INTERIOR. The system also includes a radio central 12, a cellular network communication system 13 type SM, GPRS or uMIS, with loudspeakers 14, 15, placed at the back of the vehicle at the top of the driver's seat FOR LENSMELLRE IGOLMENL VOICE COMMUNICATIONS TO THE DRIVER AND TO VEHICLE PAGGERS. Loudspeakers 14 and 15 can be neutralized so as not to disturb the conduct of the driver. a digital radio broadcaster for the general public 16 eGL {also coupled to the central cenLale of LraiLemenL 3 to allow the recording of advertising or announcements in the data base 5.

requesting client.

  The navigation system of Figure 1 is based on a precise location of the vehicle. This location is obtained by the combined means of an odometer, not shown, measuring the distances traveled by the vehicle, a gyrometer and / or accelerometers, not shown, indicating changes in direction and a radio navigation system. by satellites, not shown, of the type known for example under the English abbreviation GPS of "Global Positioning System", all of these means

  forming part of the location system 9.

  According to a variant implementation of the system according to the invention, the localization system 9 can also be constituted by a radio direction finder making it possible to locate the vehicle by triangulation from waves transmitted by non-transmitting beacons

  shown, arranged outside the vehicle.

  In order to keep the passenger constantly informed about the environment of the vehicle, a card integrated in a window of the touch screen located at the rear of the vehicle, allows passengers to quickly and permanently see where the vehicle is located. than the surrounding important elements. This map changes according to the local coordinates of the vehicle. A configuration mode of the touch screen allowing the viewing of Internet pages is represented in FIG. 2. This comprises in its upper part a banner area 17 comprising the reference to an HTML page of fixed size, an area of functional keys or buttons 18 occupying a margin on the left of the screen, an area 19 reserved for recording messages, an area 20 for recording the date and time, an area 21 for recording the cost of the taxi ride and an area 22 reserved for

the display of Internet pages.

  Zone 17 is always present on the screen and its content can be modified by the operator. When a general menu is displayed, it is possible to provide in the banner direct access keys to a predefined website (association with an English abbreviation URL for "Uniform Resource Locator") which can then take control of the page user. Apart from this case, the banner does not contain keys allowing direct access to a site. A page can be displayed according to a combination of days of the week, days of the year, time of day, current service. Zone 18 is a fixed-size zone occupied by tactile function keys making it possible to offer the passenger a determined number of basic Internet network services such as reading their mailbox, sending a message, browsing the network, help . But the operator can also add keys to give access to information contained in pages in HTML format. The size of the keys is then automatically adjusted according to the available space of the zone. These keys constitute as many interactive terminals which allow the scrolling of pages

  displays on the touch screen display.

  Zone 19 is managed by the outdoor station which communicates with the vehicle and which transmits messages

to the passenger.

  Zone 22 is reserved for viewing HTML pages intended for passengers. It allows passengers to consult their mailbox and browse the Internet. By permanently knowing the position of the vehicle in latitude and longitude and by predicting the route to be performed, the processing unit 3 selects from the database 5 the documents to be automatically distributed. I1 can be documents

  multimedia, video, graphics, OR advertising.

  These documents include banners with hyperlinks to Internet sites allowing you to initiate a telephone call to an operator. They can also be information programs on the life of neighborhoods such as exhibitions, leisure, restaurants, entertainment. Hyperlinks also allow

lead to advertisers' sites.

  do not combine other services classified by category such as reads of bangles, historical monuments, muses, ball dislibers, hotels, resilaurants, if any, in the reverse region by the vehicle rarely displayed. It is also possible to display maps of the Lraverses zones enriched with InmenLs InGeRGanL the paGGager reprAsenL @ G by permanently conglulable icanes. Finally, a window 21 like that shown in Figure 3, shows a window on the car followed by the vehicle as well as its "V" position on the car can also be incremented c5L or in zone 22 by simple selection on a Appropriate area control button

18 for example.

  UPDATED CONTENTS OF THE DATA BAND 5 eGL effected by a link on a radio channel

  RECEIVER 10 AND THE CENTRAL GLALION 1 WHICH LAUNCHES HAUL DEBIL LANSMIGGIONG. THIS MIX IS CONSISTED OF A PARL, RETRIEVE FROM THE SERVER 11 THE GEOGRAPHIC NECESSARY TO THE REPRESENTATION SEEN ON THE LACLE SCREEN OF THE VEHICLE POSITION, ORGANS THIS POSITION, APPEARING OUTSIDE THE REGIONAL GEOGRAPHICAL FIELD IN THE OTHERS database. parL, leG informaLionG enLouranL of points of interest in correspondence with the geographic map in use. The repatriation of the card and the information corresponding to a point of interest on the card can be done in the manner shown by Lapes 24 to 30 of the flowchart in Figure 4. In step 24 the coordinates in latitude and longitude of the vehicle are compared to the latitudes and longitudes of the edges of the map in use and if the result of the comparison shows that the coordinates of the vehicle are outside the limits of the map, then a request to load the map bordering on the edge by which the trace of the vehicle on the card in use has disappeared is carried out in step 26 by the processing unit 3 to the external server via

  high speed digital radio link.

  It is also possible according to another embodiment of the invention to display the movements of the vehicle on a scrolling map in the window of the display touch screen relative to the location of the vehicle, this point remaining in a fixed position at center of the viewing window 23. As before, the geographic data corresponding to the added or removed borders are transmitted by the external server on the high-speed digital broadcasting radio channel. In steps 27 and 28 when the position of the vehicle is close to a point of interest, a restaurant for example, this point of interest

  is indicated in step 29 by an icon on the touch screen.

  Pressing this icon allows step 30 to retrieve information concerning this point of interest from the external server into zone 22 of the touch screen via the high speed digital radio link if the content is not

  present in the processing unit 3.

  The announcements of the advertising campaigns can be viewed in two formats, a small banner format in zone 17 for example when the taxi user uses the system interactively or in large format in zone 22 for example if he is passive. But announcements can also appear at specific points on the map. Ads are eligible according to rules taking into account the time and positioning of the taxi in space. To avoid a conflict when several advertisements are eligible at the same time, a priority coefficient can be assigned to each advertisement. In this management, it is taken into account that the same advertisement can belong to several campaigns at the same time. The corresponding database dedicated to announcements is managed by the system. The trailers can be animated (animated images, flash, video) with a very short display duration of the order of a few tens of seconds to create a visual change and thus attract the eye of the

passenger passenger.

  If the behavior of the user becomes interactive, the screen switches automatically to keep an announcement banner 17 and an interaction area 22. The announcement banner is itself tactile and it refers to the site (pre-loaded or online) from the advertiser; the display being done in the interaction zone, the banner

continuing on the other announcements.

  The choice of technologies is deliberately oriented towards tools from the Internet: Web server, XML language, display system in the form of

browsers.

  One of the main advantages is that any passage of an advertisement or any interaction on the part of the user is recorded according to a format defined by the web server, this technique which is standardized with the advantage that it allows to take advantage of a considerable number of tools for analyzing these traces in order to present them in a synthetic way or even to facilitate coupling with "back-office" tools for aspects such as billing to advertisers for a certain number of passengers with the number of different users who interacted with the ad and the detail

on the pages of the site visited.

  Thus structured, the system according to the invention allows efficient management of taxi fleets. In this management, each taxi is considered to belong to a group of taxis. Each group represents all of the taxis operating the same advertising campaign. The assignment of a taxi to a group is subject to review each time an ad campaign is changed. A taxi is considered at all times to belong to only one group. A database containing the profile of

  individual customers is managed by the system.

  The management of points of interest is carried out by associating the coordinates expressed in longitude / latitude

and address.

  The system is active after each broadcast of an advertisement. To elect an advertisement, the system takes into account parameters such as the position of the taxi and its proximity to a point of interest on the map, a time slot, a level of priority over other advertisements, the number of times the advertisement passes. . A default ad election mode, when no ad responds

  to the previous criteria can also be expected.

  To reserve a taxi, the system also includes the elements shown in FIG. 1 of mobile radiotelephones of a cellular communication network as well as electronic locator boxes. These elements are made available to users of the taxi network, each user having a mobile telephone 31 and an electronic locator unit 32. In the electronic locator unit 32 is also integrated a radio navigation satellite receiver similar to GPS to that residing in the location system 9 of the

figure 1.

  According to the invention, in order to call a taxi, each person or customer calling must put in contact by a physical, acoustic or infrared link, for example, their locator unit 32 with their mobile telephone 31, in order to allow the transmission of data from the location and idenLiLd of the caller locator 32 in the mobile phone 31. According to another mode of realization of the invention, it is also possible to merge the composAl alAmenLs the locator 32 and those dial the mobile phone 31

in a same wood.

  The reservation process is carried out following the Lapes referenced from 33 40 on the flowchart of figure 6. The procAd starts the @ Lape 30 by a call of the client who dials on the keyboard of his L @ mobile phone an idenLifianL number a Laxi service in the cellular communication network. At the request of this call, the central glaLion of geGLion 1 invites the client to step 34 by a voice of synLb @ Ge to couple, acologically or optically or denulably by a physical link, the box locator 32 with the mobile phone 31 for perm on the other hand, LansferL lape 35 of the geographic location data caleules by the receiver of radio navigation GPS inL6grA to the locator case 32 to the central GLaLion of geGLion 1 by the L4lAphone mobile 3I eL of other parL, the caller ID memorizes the interior of the case.

  Once the client has given his agreement, he can go to the place that has been indicated to him by the station.

central management.

  As shown in the perspective view of FIG. 5, each locator unit 32 is provided with a chip card reader 41, a call button 42 and a visualization Acran [C 43. The unit 32 integrated in the way shown in Figure 7, a microprocessor archiLecLore composed of a localization module by saLelliLe Lype CES 44, a 1st connection by acouGLic modem for the LansterL by means for example of a modulaLion of a signa1 baGGe frequency two tats phase, location and identification data towards the microphone of the mobile phone, and possibly a memory module 46 of the SIM micromodule type which is used in the mobile phones of the S system to store the caller's own parameters. allowing its authentication. The parameters are provided, for example, by the introduction of a chip containing the confidential code in the chip card reader 41 or better by recognition of the customer's fingerprint according to suitable means comprising for example means for reading the footprints on a touch screen not shown. All of AlmenLs 2s 41, 44.45 and 46 are coupled to a microprocessor 47 by an eL data bus 48. e microprocessor 47 eGL suitably programmed to carry out data changes between the locator case 32 and the central station from geGLion 1. an example of [orming data to perform ceG changeG eGt shown to

figureG 8 and 9. In figure 8 the meGGage put by the locator unit 32 includes

  three main zonesG, a first zone 21 and a second zone z2 codes each with a binary word of 22 bits respectively give the longitude E / W and the latitude N / S expressed in degrees, minus the seconds of the position of the calling customer eL a third zoe z3 code for example on 32 bits corresponds to the diauthentificatio code of the calling customer memorized in the memory module 20. The bits contained in zone 21 serve as address pointer of a Lable of longitude 48 contained in a memory of data management system of the central management region 2. Leg bits of zone 22 servinL of poWer of adgeGe of a word M1 inside Lable 23 G @ lecLionnde by the bits of zone 21. The word M1 identifies the street and the street number which is closest to the position of the calling customer. Even if necessary, the data processing system of the Central Generation will be able to calculate the distance which separates in the

  Street the customer calling the number indicated by the word M1.

  In the case where the longitudinal and latitude data calculated by the satellite positioning module 44 GeraienL expressed in grade, the formatting of the localization message of figure 8 will have to be modified accordingly. In FIG. 9, the message which is set by the central management GLAION 1 locating box locator 32 to allow identification by the Laxi customer which is sent by the central management station 1 comprises 5 reference zones of Z4 Z8 defining respectively the make of the vehicle, its model, its color, the time spent, and a message inviting for example the customer to call

  confirmation that he is willing to wait for the taxi.

  According to a variant embodiment of the invention, each localizer box integrates in addition a radio communication module short distance radio frequency referenced 49 in FIG. 7, allows to establish a 1st radio connection to the alternation of Lype "taled walEman" with the Laxi radio center 12. This provision allows a 3s Laxi when he finds it difficult to find Gon

  client, to establish a dialogue with him.

  The proximity link of the "taled walkman" type can, according to a more elaborate option, be selective by carrying out digital speech transmission. It consists in having the central management station 1 transmit a code number identical to a code number already stored in the memory module 46 of the locator unit towards the taxi responsible for carrying out the journey, and in encrypting speech by this code number, which makes the speech exchanged for other locator boxes and taxis located nearby unintelligible. In this case, we can also use a code provided by a

random code generator.

  According to an even more elaborate version of the invention, the locator unit can be used by the customer to interrogate the data processing unit 3 of the taxi by transmitting, all of the data necessary for connection with his messaging system or an Internet site or still specialized services. This data can be written to the memory module 46 or to a SIM card. For this, it suffices to incorporate in the locator unit a modem 50 of the type produced for example according to known technology according to the Anglo-Saxon designation "bluetouth" making it possible to ensure a link by ultrashort wave with the unit

treatment.

  The selection of an "e-mail" e-mail address is then carried out by successive pressing of a key provided for this purpose on the unit, each of them corresponding to a pre-programmed e-mail address or website. In this selection each press on a key causes the display of a number or an alphanumeric character on the representative display screen

  a preprogrammed site or e-mail address.

  In implementing the system according to the invention which has just been described, it is necessary to operate in three successive stages, a first stage consisting in preparing the advertiser's advertising campaign, a second stage consisting in managing in each taxi the advertising campaign which was prepared during the first stage, and a third stage which proceeds

  the analysis of the campaign results.

  The first stage consists in preparing and testing the posters of the advertisers, in assigning on the map places of diffusion (POI points of interest), in declaring the level of priority according to the price of the passage or the race. The assignment of one or more POI points of interest is carried out interactively by viewing the map or automatically using a list of coordinates in longitude and latitude for example, or a list of addresses defined for example by a postal code, city name, street name, street number. A geocoding API is provided by the mapping system to allow the display composition system to find coordinates expressed in latitude and longitude from a street address in a city. If the mapping system is unable to find the address automatically, it offers the operator the possibility of performing interactive positioning by displaying the district map. The display composition system is responsible for memorizing the usual coordinates of an advertiser to facilitate possible future use. Preferably, POI points of interest are grouped together by theme, the latter being able to be active or inactive in a given ad campaign, a symbol or icon being attached to a theme to facilitate their visualization. The same location which can present several points of interest. Updates to the corresponding databases are made regularly at the end

day for example.

  During the second stage, during the advertising campaign, in each taxi the day is broken down into a set of races corresponding to customer support. A trip is limited by the place of embarkation which can be known automatically thanks to the radio central station in PMR connection on the front of the taxi, (API to be defined) and the place of destination. The driver indicates the place of destination via the touchscreen terminal at the front presenting a man-machine interface offered by the mapping system. This can be done by a sequence of the type (choice of the department) then (choice of the first letter of the destination city on an alphabet) then (choice in a list of the city) then (choice of the first letter of the street ) then (choice of street from a list) then (dialing the street number). The mapping system can then calculate the route. The route is called into question each time the driver does not follow the navigation indications which appear by arrows on the front terminal (voice announcements in addition) and according to the traffic information. Advertisers' posters are then distributed within each taxi according to an election algorithm according to the position, priority, time and number of passages already made. The display system periodically interrogates the mapping system to find out the list of points of interest located in the area of influence in front of the taxi; this list containing for each POI the information supplied at the time of allocation of step 1 of the day before. For reasons of animation behind the taxi, the on-board mapping system generates, in the form of Web pages, the visualization of the dynamic position of the taxi on a fixed and zoomable map or the visualization of an animated map. depending on the movements of the taxi (taxi: fixed point on the screen) and on the other hand the road map followed, the POIs can be clickable according to the zoom level compared to their number; one click

  on a POI showing the trailer of the place.

  In real time, specific information can also be reported, for example on pollution measurement results provided by

  sensors installed in each taxi.

  The analysis of the campaign which takes place during the third stage consists in carrying out an analysis of the dissemination statistics of the results of questionnaires proposed to passengers and also to drivers and to the coupling with the "Backoffice" of the billing system.
