Description

  The present invention relates to a telephone communication device for automobiles.

  In the prior art, mobile telephones are already built into automobiles. When there is an incoming call, a bell is made in the car to inform the driver of the incoming call. When in a dangerous driving situation, the driver first receives a ringing bell sound as unpleasant. Next, when the driver responds with the handset moving or does not answer, the driver loses the opportunity to listen to the telephone communication. In any situation, the driver is subjected to harmful stresses on the one hand for driving safety and on the other hand for the quality of telephone communication.

  In JP-A-11130864, there is already a problem of detecting the driving status of a car for commanding the connection of a mobile telephone based on the detection of data representing the driving status for a connection, that is, a line use command. Has been raised. In this prior art, the mobile phone is connected to the connection box of the car via a connection and the signal indicates that the car has received a radio transmission or reception signal. A signal representing the speed of the car is sent to the sorting section. The sorting unit estimates the driving situation of the driver based on the speed of the automobile and determines whether or not a communication signal should be transmitted in the processing operation. As a result, the incoming call bell is not emitted, especially when the speed signal exceeds a predetermined threshold.

  In the international application WO 99/26393, it is proposed to use a mobile phone in a car, provided in advance with a device that allows a part of the conversation to be recorded for later broadcast. As a result, in an undesired driving situation, incoming conversations are stored in a memory element and can be retransmitted later when the undesirable driving situation ends.

  In Japanese Patent Application JP-A-200270051, by using an on-vehicle receiver that accepts an incoming call according to the driving load of the driver during the call waiting time, the safety of driving when receiving the call. It has been proposed to be able to take into account. When the driver's driving load is considered low, the incoming call is signaled to the driver by an acoustic signal. When the driver's driving load is considered high, incoming calls are cleared.

However, when telephone communication is established between two callers, the above various solutions cannot be applied when a driving situation occurs that requires the driver's full attention. If such a driving situation occurs when telephone communication is not established, the driver may not receive incoming communication, but will not be warned that there has been a call related to this communication .

When a logical “AND” step 46 detects that a stress condition and an incoming call condition occur simultaneously, a hold message generation step 48 is executed that generates a hold message. For this purpose, the computer 1 (see FIG. 1) reads an appropriate address of the call hold message memory 22 by the GSM communication control circuit 36 and extracts an appropriate hold message therefrom. The pending message is then communicated to the loudspeaker control circuit 14 and further to the loudspeaker 5. Next, the session end test 50 is executed. If the session end test is not “YES”, the process returns to the stress state detection step 42 and the incoming call detection step 44. At this stage, when only one of the stress state and the incoming call state is not detected, the pending message generation step 48 is not executed, and the stress state detection test and the incoming call detection test described above remain in the standby state. become.

  When only one of the stress state and the incoming call state is not detected, the test result of the incoming call detection step 44 is “YES”, but the test result of the stress state detection step 42 is not “YES”. Especially occurs. In this case, incoming communication can proceed. In particular, the generation of a ringing tone signal (not shown) is performed by the loudspeaker control circuit 14 and the loudspeaker 5 (FIG. 1).

  The situation where only one of the stress state and the incoming call state is not detected is when the test result of the incoming call detection step 44 is “NO” because the sender who has received the hold message does not stick to the call. Also occurs in particular.
