Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a block diagram of the configuration of this embodiment. The vehicle 100 is provided with an automobile telephone 14 and a control unit 12 that controls transmission / reception thereof. Control unit 1
2 is composed of a processor, a memory I / O port, etc.,
The data is transmitted via the antenna and the data received by the antenna is processed to control the operation of the telephone set 14. In addition, an input unit 10 for a user (vehicle driver) to input a registration number of a surrounding vehicle is provided and outputs input data to the control unit 12. The input unit 10 can be configured by a keyboard or the like, or can be configured by a microphone and a voice recognition device so that voice can be input. On the other hand, a database 300 is connected to the base station 200 that receives the vehicle registration number transmitted from the vehicle 100, and the database 300 stores the vehicle registration number and the vehicle-mounted telephone number. Then, when the registration number data is received from the vehicle 100, the base station 200 accesses the database 300, searches for the in-vehicle telephone number corresponding to the transmitted vehicle registration number, and returns the vehicle number to the vehicle 100.
In the vehicle 100 that has received the in-vehicle telephone number data from the base station 200, the control unit 12 displays the data and the vehicle driver makes a dial call based on the in-vehicle telephone number, or the control unit 12 causes the telephone set 14 to receive the telephone number. To automatically send a dial to the desired vehicle.

The configuration of this embodiment is as described above, and the processing up to dialing will be described in detail below with reference to the flowchart of FIG.

In FIG. 2, first, the registration number of the vehicle and the in-vehicle telephone number are registered in the database 300 of the base station 200. That is, when the telephone set 14 is set in the control unit 12 (S101), the control unit 12 transmits the vehicle registration number (vehicle number) and the telephone number stored in the memory in advance to the base station 200 (S102). Base station 20 that received the registration number and telephone number from vehicle 100
0 registers in the database 300 and transmits a signal indicating that registration is completed to the vehicle 100 (S20).
1). The name, address, etc. can be stored in the database 300 together with the vehicle registration number and telephone number.
If the registration number of the vehicle has been changed, it is rewritten to the new registration number and returned to the vehicle 100.

After registering the registration number and the telephone number of the own vehicle in the database 300 in this way, if it is desired to call a vehicle around the vehicle while the vehicle is running or stopped, the registration number of the vehicle (vehicle Input number 1
Enter from 0. The registration number input to the input unit 10 is output to the control unit 12, and the control unit 12 transmits the registration number to the base station 200 via the antenna (S103). Base station 200 that received registration number data from vehicle 100
Then, the database 300 is accessed, the in-vehicle telephone number corresponding to the registration number is searched, and the vehicle number is returned to the vehicle 100. The vehicle 100 receives the in-vehicle telephone number data transmitted from the base station 200 (S104). Upon receiving the in-vehicle telephone number, the control unit 12 displays the telephone number on the display unit or the like to notify the user. As a result, the user can know the telephone number of the vehicle he / she wants to make a mobile phone call to and can make a dial call (S105, S106).

In the processing flowchart of FIG. 2, the control unit 12 that receives the in-vehicle telephone number data from the base station 200.
Shows the process of displaying the telephone number on the display unit. When the in-vehicle telephone number data is received from the base station 200, the control unit 12 automatically controls the automobile telephone 14 to dial the telephone number. It is also possible.

On the other hand, when the dial transmission is made to the desired vehicle in this way, the vehicle receiving the dial transmission determines whether the incoming call is a normal car telephone or the registration number of the own vehicle. It is inconvenient to be able to determine whether it is coming from the surrounding vehicles. In other words, when the registration number of the own vehicle comes from the surrounding vehicles, it is a so-called car phone from an arbitrary third party, and in the situation of waiting for reception of another important car phone, This may happen if you do not want to receive such a call. Therefore, in the present embodiment, when a dial call is made using the telephone 14 in order to distinguish an ordinary car phone from a car phone based on the vehicle registration number in this way, the control unit 12 displays a message to that effect. Is added. The message may be before or after the dial selection signal, and the control unit 12 on the vehicle side that receives the message lights the LED or the like so that the vehicle side that receives the dial transmission can send a normal car telephone or a registration number. It is possible to discriminate whether the vehicle is a mobile phone based on the above, and if there is no intention to receive, the control unit 12 can be operated or programmed so as to cancel the reception. As the message indicating that the dial transmission is based on the registration number of the vehicle, the registration number of the transmission destination vehicle (that is, the own vehicle) and the in-vehicle telephone number are suitable. As a result, it is possible for the vehicle side that received the car phone to specify the originating vehicle and also to make a dial call to that vehicle, so that the call can be made more smoothly.

Further, in this embodiment, the base station 200
The case where the control unit 12 which received the in-vehicle telephone number data from the user automatically makes the dial call or the user inputs the telephone number to make the dial call is described. It is also conceivable that the base station 200, which has received from the vehicle 100, dials the vehicle based on the telephone number retrieved from the database 300. Also in this case, it may be preferable to add a message indicating that the vehicle is a mobile phone based on the registration number as in the present embodiment.

[0020]

As described above, according to the vehicle-mounted communication device of the first to third aspects, when the vehicle is running or stopped, the vehicle-mounted telephone can be used for other surrounding vehicles whose vehicle-mounted telephone number is unknown in advance. It is possible to make a call and to notify other vehicles of necessary information.
