Description

"Telephone communication system for vehicles" This

  The invention relates to a telephone communication system for a vehicle.

  In the state of technology, a mobile phone has already been incorporated into a vehicle. During an incoming call, a ring is played in the vehicle to warn the driver of the arrival of the call. If the driving situation is dangerous, the driver will first ring as a nuisance. Then, or he answers by activating the telephone handset, or he loses the call if he does not answer. In both situations, the driver suffers a stress detrimental to driving safety on the one hand and the quality of telephone communication on the other.

  In JP-A-1130864, the problem of detecting the driving state of the vehicle for controlling the connection of a mobile phone on the basis of the detection of data representative driving state has already been raised to control the connection or the line connection. In this state of the art, the mobile phone is connected to a vehicle connection box by means of a connection section and a signal indicates that a transmission or reception of a radio signal is received by the vehicle. A signal representative of the speed of the vehicle is sent to a discriminating section. The discrimination section derives the driving state of a driver based on the speed and decides in a processing set whether the communication signal is to be transmitted. As a result, the ringing tone of an incoming call will not be transmitted when the speed signal exceeds a certain threshold.

  In an international application, WO 99/26393, it has already been proposed to use a mobile telephone in a vehicle so that a resource enabling part of an exchange to be recorded for subsequent distribution is already provided. As a result, in an adverse driving situation, the incoming conversation may be stored in a memory element, and subsequently reissued when the adverse driving situation ceases.

  In a Japanese patent application JP-A-200270051, it has been proposed to solve the problem of taking into account driving safety when receiving a call by using a receiver on the vehicle which accepts an incoming call by according to the driver's driving load during the duration of the call. When the driving load is considered low, an incoming call is signaled to the driver by a ringing signal. When the driving load is considered important, the call signal is suppressed.

  However, these various solutions are not applicable when a driving situation requiring the full attention of the driver occurs when the telephone communication is established between the two parties. If such a situation occurs when the communication is not established, the driver can never receive the incoming communication and not be notified of the call associated with this communication.

  The invention remedies these disadvantages of the state of the art. Indeed, the invention relates to a telephone communication system for a vehicle of the type comprising: - a cradle for receiving a mobile phone; - a satellite under steering wheel to receive commands for use in a telephone conversation; - - a visual and audio signaling interface of telephone communication status.

  The invention is characterized in particular by the fact that the system furthermore comprises a computer that is electrically and / or computerically connected with the cradle, the satellite and the interface and that comprises: - a telephone communication circuit with the mobile telephone network ; - A circuit for providing the telephone communication circuit a hold message during a driving situation unsuited to the execution of a telephone exchange.

  According to one aspect of the invention, the system includes means for activating the circuit for producing a hold message by detecting an incoming call.

  According to another aspect of the invention, the means for activating the production circuit of a hold message includes means for inputting a command detected on the dashboard or other driving load element to signal by the driver the driving situation unsuitable.

  According to another aspect of the invention, the means for entering a detected command comprises a user command taking satellite for a telephone communication system.

  According to another aspect of the invention, the means for entering a detected command comprises means for addressing a telephone call waiting message memory which cooperates with a telephone call holding circuit and a transmission circuit. of telephone communication.

  According to another aspect of the invention, the telephone call standby circuit cooperates with means for performing a stress test and an incoming call detection test so that when both situations occur simultaneously, a step to generate a waiting message is executed.

  According to another aspect of the invention, the telephone call standby circuit cooperates while a telephone call is established with a stress situation detecting means, and means for transmitting an activation signal of reading the hold message memory so that a correct waiting message is then broadcast on the telephone transmission circuit.

  According to another aspect of the invention, the telephone communication calculator also comprises means for producing the display of a message, an icon and or a list of data on the display device associated with the computer.

  According to another aspect of the invention, the telephone communication system comprises a means for generating data lists comprising in particular: the identity and or the call number of the correspondent, and where the message of the call pending, which has been broadcast or its indication, and or - the date and time of the start of transmission of a hold message.

  According to another aspect of the invention, the stress situation detecting means comprises a switch disposed on the telephone communication control satellite disposed in relation to the driving position, and particularly with the steering wheel and in that it comprises at least one of the following means: a lever, a rocker button or a touch pad or any other device comprising an icon indicating a touch zone on a touch screen.

  According to another aspect of the invention, the telephone communication system is placed with an active stress-state detection system so that the driver must place the stress-state detecting switch in a state of stress. disabling so that a telephone call can be initiated by the detection of incoming call or for a telephone call can proceed.

  Other features and advantages of the present invention will be better understood from the description and drawings in which: FIG. 1 is a block diagram of a communication system embodying the invention; FIG. 2 is a flowchart of a first situation in which the system of FIG. 1 is located; FIG. 3 is a flowchart of a second situation in which the system of FIG. 1 is located.

  In Figure 1, there is shown the block diagram of a telephone communication system according to the invention. The system of the invention essentially uses components that are already used to make telephone communication systems on board a private vehicle. In the exemplary embodiment, such a telephone communication system is associated with the driving position and mainly comprises: a computer 1; a GSM 2 terminal cradle; a satellite 3 for taking a user command for a GSM telephone communication system; a sound diffusion system by loudspeaker 5; a microphone speech detection system 6; a display device for messages and pictograms 7; a GSM telephone terminal 3 connected in the GSM terminal cradle 2.

  The GSM terminal cradle 2 comprises means for maintaining the GSM telephone terminal 3 mechanically.

  The GSM terminal 3 is a mobile telephone terminal which is generally worn by the driver when he is not in the driving position or does not wish to use the mobile phone resource. On the other hand, as soon as the driver wishes to use a mobile phone resource while driving, he must mount his GSM telephone terminal 2 in the GSM terminal cradle 2 so that it is securely held.

  The GSM terminal cradle 2 also comprises means for supplying a power supply to the GSM telephone terminal 3. In this situation, a charging circuit of the mobile telephone terminal 3 is then turned on to detect whether the GSM telephone terminal 3 needs charge.

  The GSM terminal cradle 2 also comprises means for supplying electrical signals to a signaling socket of the GSM telephone terminal 3. In this situation, the telephone communication computer 1 may notably use the telephone communication card to detect the code identification and telephone number of the user of the GSM telephone terminal 3 and the call resources such as the telephone number book associated with the telephone terminal GSM 3. However, the microphone, the speaker and the display of the GSM telephone terminal 3 are not used during a communication session when the GSM telephone terminal 3 is installed in the GSM terminal cradle 2.

  The GSM communication computer 1 mainly comprises a GSM communication circuit 32 connected to an antenna 34. The GSM communication circuit 32 is connected to a GSM communication control circuit 36 which is connected to a plurality of circuits and memories by a central bus 20. Among these circuits and memories, there are: a memory 22 message waiting for telephone communication; an incoming call detection circuit 24, a telephone call waiting circuit 26, a GSM transmission circuit 28, a GSM reception circuit 30; a control circuit 10 of the GSM cradle; a circuit 12 for controlling the GSM satellite; a circuit 14 for controlling the loudspeakers; a circuit 16 for controlling the control of the microphones; and a circuit 18 for controlling the signaling devices of the telephone communication state.

  FIG. 2 shows a flowchart of a first situation in which the telephone communication system of FIG. 1 is placed. During step 40 of beginning of operation of the communication system of the invention no conversation or telephone communication has yet been initiated. During steps 42 and 44, respectively a test for detecting a stress situation and an incoming call detection test are executed. When both situations occur simultaneously, which is detected by a logic and logical combination 46, an additional step for generating a wait message 48 is executed. For this purpose, the computer 1 (see FIG. 1), by virtue of its communication control circuit 36, executes the reading of a suitable address of the memory 22 of the hold messages to pick up a hold message therein. which is then transmitted to the control circuit of the loudspeakers 14, then to the loudspeakers 5. Then a test of end of session is executed and if the end-of-session test 50 is not positive, it returns to detection 42 of the stress situation and detection 44 of an incoming call. If only one of the two conditions is no longer fulfilled, the step for generating a waiting message 48 is no longer executed and the detection situation mentioned above is still pending.

  Especially such a situation occurs when, while the incoming call detection 44 is still positive, the detection of the stress situation 42 is no longer positive. In this case, the incoming communication can progress. In particular, the ringing tone signal (not shown) is then executed using the control circuit 14 and the speaker 5 (see Figure 1).

  Particularly, such a situation also occurs when the incoming call detection test 44 is negative because the caller does not hold his call when he hears the hold message.

  FIG. 3 shows a flowchart of a second situation in which the telephone communication system of FIG. 1 is placed. In step 60 of beginning of operation of the communication system of the invention, uses the incoming call detection procedure as previously described and the telephone call is then established according to the usual procedures and protocols.

  During a step 62 of detecting a stress situation, a signal activating the reading of the memory 22 waiting message (see Figure 1) is then issued and the correct waiting message is then broadcast on the GSM transmission circuit 28. As long as the communication is not deemed terminated by an end-of-session test 66, the loop resumes to test the stress situation detection condition of step 62. The message standby is then repeated during step 64.

  In a particular embodiment, the telephone communication computer 1 also comprises a means for producing the display of a message, an icon and or a list of data on the display device 7 associated with the computer 1, of so that the state in which the telephone communication system is located can be signaled, at least at certain times, to the attention of the driver. Such a message may indicate that a state of stress situation is currently active and that blocks the transmission or continuation of a call or a telephone call. An icon may be provided to indicate this state. A list is used to indicate in particular: - the identity and / or number of the correspondent of the correspondent, and where - the waiting message that has been broadcast or its indication, and or - the date and the start time of sending a hold message.

  It is thus possible for the driver to determine the party who has been interrupted, as well as the passage of the call and / or the moment of interruption of the call.

  In a particular embodiment, the detection of the stress situation performed during the tests 42 (FIG. 2) or 62 (FIG. 3) is performed on the basis of the state of a switch disposed on the GSM control satellite 4. . Such a GSM control satellite is arranged in relation to the driving position, and particularly with the steering wheel as already known. The stress situation detecting switch according to the invention may comprise a lever, a rocker button or a touch pad or any other device comprising an icon indicating a touch zone on a touch screen, which can then cooperate with the device 7 which is naturally incorporated in the telephone communication system of the invention. In such an embodiment, the stress situation is detected directly by the driver himself, who then determines the state in which the communication system of the invention should be.

  In a particular embodiment, the telephone communication system according to the invention is naturally placed with a stress situation detection system in the active state. As a result, in such an embodiment, the driver must set the stress state detecting switch to a state of disabling so that a telephone call can be initiated by the incoming call detection or else a telephone call can take place.

  The present invention is not exclusive of other stress situation detection systems. i0
