Definitions

  • the present invention relates to the technical field of assistance in driving motor vehicles. More specifically, it relates to a method and a device enabling the driver to use real-time traffic information relating to a route or to a geographical area.
  • Numerous driving assistance systems for motor vehicles comprising an information processing unit, a display screen connected thereto, and a control device enabling the driver to control the entire system.
  • the information processed is, depending on the case, information specific to the vehicle delivered by on-board sensors such as wheel speed or steering angle sensors, cartographic information stored in a vehicle mass memory or on laser discs. , or even information received by radio, concerning either the location of the vehicle or road traffic.
  • the applicant's publication FR2 656 966 relating to a management and command system for at least two on-board communication devices, proposes to integrate in a vehicle a management and command unit with which these devices communicate permanently. by mutually exchanging coded messages. Furthermore, an instruction unit receives the control commands from the user, and transforms these into internal instructions for that of the devices which is temporarily the only one in communication with it, while managing a display means.
  • This publication provides in particular that one of the two on-board communication devices is precisely driver assistance equipment, without however specifying the nature or the operation of this equipment.
  • the invention provides a driving assistance method and device based on radio reception of traffic information and on the active dialogue of different communication devices.
  • the present invention relates to a driving assistance method for a motor vehicle based on the reception of road traffic information by radio, as well as on their use in real time by the driver.
  • This method is characterized, on the one hand, in that the driver simultaneously controls the choice of a route or a predefined geographical area and the listening or consultation of information relating to this route or this area, and d on the other hand in that it permanently masters the simultaneous exploitation or not of other modes of communication and the corresponding use of common restitution organs.
  • the other exploitable communication modes include listening to a car radio and / or using a radiotelephone and / or using a laser disc player.
  • the routes or the predefined geographical areas are memorized and stored on board the vehicle.
  • the traffic information received is restored in visual form.
  • the traffic information received is restored in audible form.
  • the present invention also relates to a device designed for the implementation of this method.
  • This device is characterized in that it comprises a traffic information decoder and at least one other communication device connected to a central control unit provided with a common communication bus allowing the traffic information decoder and the other devices of communication to dialogue between them, and to access the common restitution bodies.
  • the other communication devices are a radiotelephone, and / or a car radio, and / or a laser disc player.
  • the driver controls the dialogue between the decoder and the other communication devices from a satellite placed under the steering wheel of the vehicle.
  • the sound reproduction of the traffic information is provided by means of a speech synthesis system.
  • the sound reproduction member is constituted by the set ble of the vehicle speakers
  • the visual restitution member is a display screen arranged near the dashboard.
  • the traffic information decoder is integrated into the car radio.
  • the central unit provides sound management so as to trigger the automatic reduction of the sound volume of the radio of the laser disc player during the audio playback of traffic information and / or during telephone conversations.
  • the central unit automatically generates the display on the screen, of pictograms indicating the selected device, when the operation of the latter is not accompanied by a visual reproduction.
  • a central control unit 1 has been shown schematically. This comprises a communication bus (not shown), allowing different communication devices (2, 2 ', 4, 6, 8) to communicate, under the control of the user. These devices are as follows.
  • a radio 2, connected to an antenna 3 allows the user to receive all of the radio programs broadcast on the usual channels.
  • the radio 2 can be equipped with an R.D.S. (Radio Data system) 2 'not shown in the figure, giving in particular access to road and urban information broadcast by the TMC (Trafic Message Channel).
  • the decoder 2 ′ may be independent of the radio 2, or even be mounted in place of the latter.
  • the central unit 1 is also connected to a laser disc reader 6 and to a memory card reader 4 5.
  • the laser disc reader 6 can be integrated into the RDS 2.2 'radio receiver set.
  • the reader 6 allows the user to have access to recorded musical programs or driving assistance information such as road maps or route indications which can be reproduced on the display or viewing screen 7.
  • the reading of an appropriate memory card 5 by the reader 4 ensures filtering of the received traffic information, relating to the geographic sector or to the route selected by the user.
  • the traffic information captured and selected can be reproduced in graphic form or in audible form. In the first case, this information is displayed in the form of a message on a screen 7 arranged near the dashboard.
  • a speech synthesis apparatus known per se and not mentioned in FIG. 1, will ensure their restitution via the speakers 10 of the vehicle.
  • the radiotelephone 8 can also be equipped with a radiotelephone 8, connected to an 8 'microphone.
  • the screen 7 and the microphone 8 ' will be arranged for example on the dashboard, near the tachometer.
  • the microphone 8 ' makes it possible, in a known manner, to use the radiotelephone 8 while keeping your hands free while driving.
  • the functional diagram of Figure 2 highlights the links between some of the organs (2, 2 ', 6, 7, 8, 8', 9) mentioned above.
  • the driver selects using satellite 9 the reception of traffic information, listening to the radio 2, the use of the laser disc player 6 or that of the radiotelephone 8. He also has the possibility to choose between a graphic restitution on the screen 7, or a sound restitution through the speakers 10 by adjusting their sound volume.
  • the screen 7 is not used (use of the radio, the player 6, the radiotelephone) the invention provides that the corresponding operating mode is displayed automatically on the screen 7, under the control of the central unit 1, using pictograms or graphic symbols.
  • the device which has just been described allows the user to have real-time visual or audible traffic information relating to the journey or to the geographic area of interest, while having the possibility of instantly retaining or finding the use of other communication devices.
  • the invention is based on the sharing of the resources of the display 7, the loudspeakers 10 and the satellite control 9 between the car radio 2, the RDS decoder 2 ′, the radiotelephone 8 and the disc player laser 6 or possibly other devices not mentioned in this description.
  • the central unit 1 is also responsible for automatically triggering the display on the screen of the pictograms indicating the selected operating mode, when the latter is not accompanied by visual feedback (listening to the radio, laser discs, use of the radiotelephone, and restitution of traffic information exclusively by audio).
