Definitions

  • the present invention relates to an on-board receiver for assisting the navigation of a motor vehicle capable of receiving, by transmitters and a specific broadcasting channel, coded messages containing at least problem locations of a finite sequence of locations set. stored in the receiver, the latter comprising means for decoding messages, means for restoring, in a form accessible to a motorist, messages received and stored, memory means containing geographic data relating to a determined geographic area and means of route crosses controllable by the motorist.
  • the radio data system RDS Radio Data System
  • TMC Traffic message channel
  • TMC Traffic message channel
  • the RDS system is based on a reference table, containing in particular numbers associated in a one-to-one fashion with predetermined problem locations.
  • the problem location table (PL table) is stored in the on-board receiver.
  • Information on a problem can be associated with advice (turn away from X), information on weather conditions, etc.
  • an RDS receiver receiving a coded problem message, decodes its cause, its effect as well as, using the stored table PL, the number or numbers of locations of the problem before, using a synthesizer, to restore the message in voice form (slowdown from A to B due to an accident, for example).
  • the present invention relates to an on-board receiver of the type mentioned above, characterized in that it comprises means for selecting and storing messages arranged to receive, from said decoding means, restored messages, for select them and store them under the control of said memory means and said route selection means.
  • the receiver keeps only the messages relevant to this route and possibly neighboring diversion routes.
  • the volume of equipment is thus limited, while the access time to the fewer stored messages is reduced, which allows the use of simpler equipment therefore less costly in terms of memory means and means management of these.
  • the route selection means include speech processing means performing voice recognition.
  • the motorist can choose their route without having to use a keyboard whose use is not always user-friendly and is not recommended when the vehicle is in motion.
  • the speech processing means can be arranged to perform speech recognition of the multi-speaker type. Any motorist, driver or passenger can thus choose a route without having to make the receiver learn voice recognition.
  • the speech processing means can also be arranged to perform a speech synthesis and control the reproduction means. This avoids duplication of certain means used for speech analysis and synthesis.
  • the speech processing means are advantageously arranged to perform speech synthesis by rules, which makes it possible to have an unlimited vocabulary, if necessary in several languages, since diphones are used to reconstitute the words, diphones in limited number.
  • the quality, in particular the transitions at the end of a word or sentence is better than with a synthesis by words.
  • the restitution means may include a display, so as, for example, to avoid disturbing the listening to a cassette or the radio by an audible message.
  • time base means programmable by the latter, can advantageously be provided to activate the receiver at a time previously determined by the motorist.
  • the message decoding means, the message selection means and the speech processing means are included in a signal processor.
  • the sequence of the various tasks of the receiver is thus simplified, since it is the signal processor which determines this sequence.
  • means may be provided that are sensitive to the opening of a door of the motor vehicle and, in such cases, activate the speech processing means. The motorist can thus, after selecting a route, immediately take cognizance of any stored messages.
  • a memory module can include the geographic data, the program used for the selection means, the data relating to said problems and the data for speech processing. It is thus possible, for example, to have only one memory component of appropriate size, managed in access sharing.
  • the receiver is installed in a car, not shown, and it comprises a reception antenna 11 connected to an input of a demodulator 12 connected at output to a signal processing processor 13 and transmitting to it in a usable form by the latter, signals representative of signals received by the antenna 11.
  • the signals correspond to broadcast messages, here of the RDS type, and transmitted by a TMC channel.
  • the RDS system is defined in a specification of the European Broadcasting Union, published in March 1984 and bearing the reference Tech. 3244- F.
  • the processor 13 is also connected at the input, by interface circuits not shown, respectively to a microphone 14 as well as to an alphanumeric keyboard 15 located on the dashboard of the car and usable by the motorist to issue commands. to the receiver.
  • a memory 26 for processing phonic signals, of ROM type, connected to bus 16, comprises databases intended for an analysis of the phonic signals arriving, by the microphone 14, at the processor 13 and at a speech synthesis for the control by the latter of the speaker 23.
  • the analysis of the voice signals coming from the motorist is of the multi-speaker type, that is to say that the voice recognition does not require learning on the part of the receiver.
  • the vocabulary to recognize is of limited volume. Speech synthesis is carried out in a known manner by rules, from diphones stored in the processing memory 26 and using, from codes representing words to be synthesized, an adapted algorithm stored in this memory 26.
  • the sequencing of the operation of the processor 13 is controlled by a program memory 27, of ROM type, connected to the bus 16 and supplying the processor 13 with a desired succession of commands.
  • a time base circuit 28, located in processor 13, provides clock signals necessary for the various electronic circuits. It includes programmable counters arranged to activate the receiver, through the processor 13, at certain times previously chosen by the motorist by means of the keyboard 15 or the microphone 14. The activation of the receiver can also be carried out automatically, during the opening of the driver's side door, by the change of state of a breaking contactor 29, when the associated door is open, the electrical continuity of a looped wire, represented schematically by a single connection, of which the two ends are respectively connected to processor 13.
  • the deactivation of the receiver is controlled from a relay 30, represented schematically by a movable blade, the coil of which is supplied when the ignition key of the car is in position electrically supplying the engine of this, and which, in the opposite case, interrupts the electrical continuity of a looped wire, represented in a wired fashion, the two ends of which are respectively connected to processor 13.
  • a relay 30 represented schematically by a movable blade, the coil of which is supplied when the ignition key of the car is in position electrically supplying the engine of this, and which, in the opposite case, interrupts the electrical continuity of a looped wire, represented in a wired fashion, the two ends of which are respectively connected to processor 13.
  • the operation of the receiver is as follows.
  • the motorist provides the receiver, by means of the microphone 14, with a choice of a route, limiting himself to the vocabulary provided, limited for example to the numbers from 0 to 9, to letters of the alphabet. and a few words, such as "AND”, “OR”, common names designating communication routes, such as “street”, “highway” and other words commonly used to designate a route.
  • the vocabulary above makes it possible to name geographical zones and to define a restricted geographical zone common to these. It also makes it possible to associate geographic areas and in particular restricted geographic areas. This is done by combinations controlled by the words “AND” and “OR” above which designate logical operators “AND” and “OR” corresponding respectively to an intersection and to a logical union. For example, if the name of a highway has been entered by voice, therefore representing a road axis, then the word "AND” followed by the name of a geographical area representing a surface, this determines a restricted geographical area which is a section of highway located in this geographic area. Word “OR” is used for its part, for example, to end-to-end various route sections defined as above, defining a total chosen route, this by means of a logical meeting of routes elementary.
  • the processor 13 performs the above determination by first analyzing the phonic signals coming from the microphone 14, by means of the algorithms contained in the processing memory 26. If words, or simply numbers or letters, are thus recognized, they are, in a first step, assembled judiciously to group, for example, a letter A followed by a number 6 which would designate a motorway named A6 and, moreover, group other symbols, for example the numbers 7 and 5 designating a geographic area named 75. If the word "AND" is recognized between A6 and 75, the processor 13 determines that it is the portion of the A6 motorway included in the geographic area 75.
  • the processor 13 By sending to the transcoding memory 25, in a following step, the code words of the geographical areas A6 and 75 as well as a code word representing the logical operator "AND", the processor 13 receives in return a code word of route, designating the section of the A6 motorway concerned, which it stores in the route memory 24.
  • the above section must however be located within the predetermined geographical extent relating to the transcoding table. If necessary, this operation is repeated for the various sections of route mentioned above, which are each defined by geographical names and by logical operators of their own. The names of several complete routes can thus be initially stored.
  • An identification code word specific to each stored route is also introduced. by the driver and stored with the route code word.
  • the processor 13 In order to avoid errors when the processor 13 stores the choice of a route in the route memory 24, read-only memory which will keep its data even after the receiver is switched off, the processor 13 retranscribes, on the display 22, the choice of recognized route, in the form of the names of the recognized geographical areas, accompanied by the indication of the logical mode of combination of these areas as expressed by the motorist by means of the logical operator.
  • the display can be simply a transcription of the commands coming from the motorist or it can be reshaped by the processor 13, to be more explicit, for example by designating, by words which are specific to it, the chosen route , words associated with the code word of the latter.
  • the messages displayed come from the memory 21 of messages to be presented, previously and temporarily filled for this purpose by the processor 13, in the format desired for the display 22, by means of the code words recognized phonically.
  • the motorist validates or invalidates the recognized choice by means of the microphone 14 or by pressing a key, among two possible, on the keyboard 15.
  • the voice recognition function due to noise, it is planned to activate it only for a few minutes after the change of state of the contactor 29 or after action on the keyboard 15.
  • the change of state of the contactor 29 also has the effect of deactivating the receiver, after a time delay of a few minutes made by the time base circuit 28, if the car engine is stopped, which is detected by the relay 30, of which the change of state is perceived by the microprocessor 13 and transmitted to the time base circuit 28.
  • the messages contained in the RAM 20 are then previously saved in a part reserved for this purpose in the EEPROM memory 24 and retransferred in the RAM 20 during the subsequent activation of the receiver.
  • a restitution, in voice form, of the identity of the chosen route is also, in this example, carried out, the processor 13 sending to the processing memory 26 code words representing the words to be synthesized and the latter providing it then in return a series of logic signals.
  • the processor 13 transforms these into an analog electrical signal formed by the coupler of the speaker 23 and modulates the latter to make it phonically restore the electronically synthesized voice signal.
  • the motorist can then subsequently select one.
  • the stored routes are displayed on the display 22 or spoken by voice synthesis, one of these then being selected, as well as its direction, by a voice command or by keyboard 15.
  • the broadcast messages received by the antenna 11 reach, by the demodulator 12, the processor 13 which performs a sorting among them according to the route selected last.
  • the processor 13 determines whether it relates to a location relating to the selected route, so as to store the message only in this case.
  • the route code word or words corresponding to the selected route are transmitted to the transcoding memory 25, which provides in response a list of the problem location code words potentials relating to the selected route, that is to say located on it or in its vicinity, on diversion routes.
  • the processor 13 then performs a comparison between the location code word contained in the received message, designating a location where there is a problem, and the above list of location code words relating to the selected route. If one of the location code words in the list corresponds to that of the message received, the processor 13 then commands the storage of the message in the message memory 20. Otherwise, the message is lost.
  • the storage in the memory 20 in fact relates to a restored message, corresponding to the received message which has been transmitted for transcoding to the transcoding memory 25 in order to have in return a restored message containing information understandable by the motorist as regards is the locations and nature of the problems.
  • the processor 13 thus stores only the messages concerning the predetermined geographical extent contained in the transcoding memory 25, insofar as they are likely to be relevant, i.e. regarding the selected route.
  • route code words makes it possible to reduce the volume of the route memory 24 and the time required to sort the messages, but that it would however be possible to initially store the raw data of route choice from the motorist.
  • the transcoding memory 25 would then be used to obtain lists of locations located in the chosen geographic areas, by carrying out the indicated logical operators making it possible to retain only the locations of the route or of its vicinity.
  • the motorist can initially program, using the keyboard 15 or by voice command with the microphone 14, the time base circuit 28 so that it activates the receiver a few moments before the expected arrival of the motorist.
  • the receiver then stores the messages concerning a selected route designated in advance by the motorist.
  • the stored messages concerning the locations of the selected route are, when they are stored, restored in voice form by the loudspeaker 23, under the control of the processor 13.
  • the motorist can order a subsequent playback thereof by action on the keyboard 15 or by means of the microphone 14, which controls the processor 13.
  • the latter has previously read the messages in the message memory 20, transmitted them to the transcoding memory 25 in order to obtain the corresponding information on the locations and the problems, in a form understandable by the motorist, then memorized these in the memory 21 of messages to be presented.
  • the above information is then transformed, at the request of the motorist, into voice transmission by means of the processing memory 26, the microprocessor 13 possibly improving the user-friendliness of the message, or else it is transmitted, in the desired form, to display 22.
  • the memory 21 of messages to be presented normally only includes messages directly concerning the selected route, but the motorist can however order the supply of messages relating to diversion routes.
  • the embodiment described above comprises memories which can be physically grouped into a single circuit which can also include processor 13.
