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 a geographic area.
- the information processed is, depending on the case, vehicle-specific information from sensors on-board such as wheel speed or angle sensors steering, map information stored in a mass memory of the vehicle or on laser discs, or information received by radio, concerning either the location of the vehicle, or road traffic.
- the integration of communication devices and means enabling the driver to exploit these appliances in the best conditions of comfort and safety installation specific management and ordering issues, including when the vehicle is fitted with more than one communication, such as a radio receiver, a radiotelephone or a laser disc player.
- Applicant's publication FR 2 656 966 relating to a management and control system for at least two on-board communication, offers to integrate a vehicle into a management and control unit with which these devices communicate permanently by exchanging mutually coded messages.
- an instruction unit receives orders user command, and transforms them into internal instructions for that of the devices which is momentarily the only one in communication with it, while managing a means display.
- This publication provides in particular that one of the two on-board communication devices be precisely a driver assistance equipment, without specifying the nature or operation of this equipment.
- FR-A-2651352 specifies the nature and the operation of such driving assistance equipment collaborating with an RDS radio receiver and relying on the radio reception of traffic information and their selection in function of parameters fixed in advance (route followed) by the driver.
- DE-A-4126435 discloses an information reception system not making such a selection, the different elements (including a laser disc player) communicate with each other with the others by means of a common bus.
- a communication bus connects a navigation module with screen, mobile phone, RDS radio receiver for radio reception of traffic information, laser disc player, as well as graphical, tactile and sound interfaces.
- this last process does not include reading routes or areas geographic data on laser discs stored on board the vehicle.
- the subject of the invention is a method of driving assistance for motor vehicle according to claim 1, based on the radio reception of traffic information and on the active dialogue of different communication devices, allowing operation of this information in real time by the driver.
- the invention also relates to a device for assisting with the conduct for the implementation of this process, in accordance with claim 5.
- the other modes of actionable communications include listening to a car radio and / or the use of a radiotelephone and / or the use of a radio player laser discs.
- the paths or the zones geographic maps are memorized and stored on board the vehicle.
- the information road vehicles received are returned in visual form.
- the information road vehicles received are returned in audio form.
- the present invention also relates to a device designed for the implementation of this process.
- This device is characterized by what it has a traffic information decoder and at least another communication device connected to a central processing unit control with a common communication bus allowing the decoder for traffic and other traffic information devices communication to dialogue among themselves, and to access organs restitution commons.
- the other devices for communication are a radiotelephone, and / or a car radio, and / or a laser disc player.
- the driver checks the dialogue between the decoder and the other devices of communication from a satellite located under the steering wheel of the vehicle.
- the sound reproduction of the traffic information is provided via a system speech synthesis.
- the restitution member sound consists of all of the vehicle's speakers
- the visual rendering device is a display screen arranged at close to the dashboard.
- the decoder traffic information is integrated into the car radio.
- the central unit ensures the sound management so as to trigger the automatic reduction of the sound volume of the radio of the laser disc player during audio playback of traffic information and / or during telephone conversations.
- the central unit generates automatically display on the screen, pictograms indicating the selected device, when its operation is not accompanied by a visual restitution.
- FIG. 1 In the center of Figure 1 there is shown schematically a unit central control unit 1. This includes 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 car radio 2 connected to an antenna 3 allows the user to receive all the radio programs broadcast on the usual channels.
- the radio 2 can be equipped with a R.D.S. decoder (Radio Data system) 2 'not appearing on the figure, giving in particular access to road and urban information broadcast by the Traffic Message Channel (TMC).
- R.D.S. decoder Radio Data system
- TMC Traffic Message Channel
- the 2 'decoder can be independent of the radio 2, or be mounted in place of it.
- the central unit 1 is also connected to a laser disc player 6 and to a memory card reader 4 5.
- the reader laser discs 6 can be integrated into the radio set-top box 2.2 'RDS.
- Reader 6 provides the user with recorded music programs or help information driving such as road maps or directions of routes that can be displayed on the display or screen of viewing 7.
- reading an appropriate memory card 5 by reader 4 filters the received traffic information, relating to the geographic sector or to the route selected by the user. Traffic information captured and selected can be reproduced in graphic form or in sound form. In the first case, this information is displayed in the form of message on a screen 7 arranged near the dashboard. In the second, a speech synthesis apparatus, known in itself and not mentioned in Figure 1 will ensure their return by through the vehicle speakers 10.
- the screen 7 and the microphone 8 ' will be arranged for example on the dashboard, near the tachometer.
- the 8 'microphone allows, in known manner, to use the radiotelephone 8 while keeping the handsfree while driving.
- the functional diagram of Figure 2 highlights the connections existing between some of the organs (2, 2 ', 6, 7, 8, 8', 9) mentioned upper.
- the driver selects using satellite 9 receiving traffic information, listening the radio 2, the use of the laser disc player 6 or that of the radiotelephone 8. It also has the possibility of choosing between a graphic display on screen 7, or audio via 10 speakers by adjusting their sound volume.
- the invention provides that the operating mode corresponding is automatically displayed on screen 7, under the control of 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 route or to the geographic area of interest while having the possibility to keep or instantly find the usage other communication devices.
- the invention is based on the sharing of the resources of display 7, speakers 10 and satellite control 9 between the radio 2, the RDS decoder 2 ', the radiotelephone 8 and the laser disc player 6 or possibly other devices not mentioned in this description.
- CPU 1 is also responsible for triggering automatically display on the screen of the pictograms indicating the selected operating mode, when this is not accompanied by visual restitution (listening to the radio, laser discs, use of the radiotelephone, and restitution of traffic information exclusively by sound).
