Description

Car Telephony System {TELEPHONE COMMUNICATION SYSTEM FOR VEHICLE}

The present invention relates to a vehicular telephone communication system.

At the current technical level, mobile phones are already being integrated into vehicles. On incoming call, there is a call to the vehicle to notify the driver of the arrival of the call. If the driving situation is dangerous, the driver first experiences an uncomfortable call. The driver then activates the telephone handset to answer, or if the driver does not answer, the driver misses the call or does either. In both situations, the driver experiences stress on the one hand on safe driving and on the other hand on the quality of telephony.

In patent JP-A-1130864, this problem has already been taken to detect the driving conditions of the vehicle for controlling the connection of the mobile phone based on the detection of representative data of the driving state for controlling the connection or rotational occupancy. . At this technical level, the mobile phone is connected to the vehicle connection unit by a connection section and the signal indicates that the transmission and reception of a radio signal is received by the vehicle. A representative signal of the speed of the vehicle is sent to the determination section. The determination section infers the driver's driving state from the representative signal based on the speed and determines whether or not a communication signal should be transmitted in the processing operation. In particular, if the speed signal exceeds a certain threshold, the incoming call is not transmitted.

In international application WO 99/26393, preparation has already been made for the use of a mobile telephone in a vehicle so that resources are first provided for the recording part of a call for a recent broadcast. During a bad driving situation, an incoming conversation can be stored in the memory device, and if the bad driving situation is stopped, it can be subsequently resent.

Was done. If the operating load is considered low, the incoming call signal is sent to the driver by the call signal. If the operating load is considered significant, the call signal is suppressed.

However, if a driving situation occurs that requires the full attention of the driver, such a variety of solutions are not applicable when telephony is established between two callers. If such a situation occurs when no communication is established, then the driver can never receive incoming communication and be notified of the call associated with this communication.

A GSM telephone terminal 3 connected to the GSM terminal cradle 2.

The GSM terminal cradle 2 comprises means for mechanically holding the GSM telephone terminal 3. The GSM telephone terminal 3 is a mobile telephone terminal generally carried by the driver when the driver is not in a driving position or does not want the driver to use mobile telephone resources. In contrast, as soon as the driver wishes to use mobile phone resources when driving, the driver must mount his GSM phone 3 in the GMS terminal cradle 2 and as a result the GSM phone 3 is secure. maintain.

The GSM terminal cradle 2 also includes means for supplying electrical power to the GSM telephone terminal 3. In this situation, the mobile telephone terminal 3 charging circuit is switched to detect whether the GSM telephone terminal 3 needs charging.

The GSM terminal cradle 2 also comprises means for supplying an electrical signal to the signal receiver of the GSM telephone terminal 3. In such a situation, in particular, the telephony computer 1 may use a telephony card that detects an identification code and a call number of a call resource and a user of the GSM phone terminal 3, such as a phone number address book associated with the GSM phone terminal 3.

The stress situation detection test and the incoming call detection test are performed in steps 42 and 44, respectively. If both situations occur at the same time and are detected by a logical " product " combination (step 46), an additional step (step 48) is generated to generate a call hold message. For this purpose, the computer 1 (see FIG. 1) asks the communication control circuit 36 to extract an appropriate call hold message from the call hold message memory 22 and to a suitable address of the call hold message memory 22. The call hold message is then sent to the loudspeaker control circuit 14 and then to the loudspeaker 5. Then, if the end of the session test (step 50) is performed and the end of the session test (step 50) is not positive, the process returns to the stress situation detection step (step 42) and the incoming call detection step (step 44). If only one of the two conditions is not fulfilled at this stage, the step of generating a call hold message (step 48) is not executed and the above-described detection situation remains undetermined.

In particular, while the incoming call detection step (step 44) is still positive, such a situation occurs when the stress situation detection step (step 42) is no longer positive. In this event, incoming communication can proceed. In particular, the call alert signal (not shown) is then executed with the help of the control circuit 14 and the loudspeaker 5 (see FIG. 1).

In particular, this situation occurs even when the incoming call detection test (step 44) is negative because the caller does not stick to his call when the caller hears the call hold message.

In the operation start step 60 of the communication system of the present invention, the incoming call detection procedure is used as previously described, and then telephone communication is established according to the general procedure and protocol.

In step 62 of detecting a stress situation, a signal is initiated to initiate reading of the call hold message memory 22 (see FIG. 1) and the correct call hold message is broadcasted via the GSM transmit circuitry 28. The loop goes back to test the stress situation detection condition of step 62 until the communication is considered to be terminated by the end of the session test (step 66). The call hold message is repeated at step 64.

In a particular embodiment, at least at a certain moment, the telephony computer 1 may display messages, icons or icons on the display device 7 associated with the computer 1 so that the state of the telephony system may bring attention to the driver. Means for generating a display of the data list. Such a message may indicate that the stress situation is generally an activation state that blocks the continuation of the transmission or call or telephone communication. An icon may be provided to indicate this state. In particular, the data list can be used to indicate:

Identification and / or call number of the caller, and / or

A broadcasted call hold message or indication thereof, and / or

-Date and time of start of transmission of the call on hold message

In this way, the driver can determine the duration of the communication and / or the moment of interruption of the communication as well as the interrupted caller.

In a particular embodiment, the stress situation detection performed during the test phase (step 42) (shown in FIG. 2) or the test phase (step 62) (shown in FIG. 3) is performed by a switch disposed on the GSM command satellite 4.
