全上からも好ましくない。Traditionally, in-vehicle telephones have been known as simultaneous call type communication devices, but because these telephones have connection cords, they cannot be used in vehicles with relatively large cabins, such as bread, wagons, and Hass cars. In order to make a call, one must move to the location where the telephone is installed. However, when moving inside the cabin of a running vehicle, unlike when moving inside a house, the movement during movement is restricted, which is inconvenient, and also undesirable from a safety standpoint.
また、従来車両通信装置として、接続コードを有しない
トランシーバが知られているが、これはブレストーク方
式を採用しており、同時通話はできない。Further, as a conventional vehicle communication device, a transceiver without a connection cord is known, but this uses a breath talk system and cannot make simultaneous calls.

うな通話が成立する。For example, when making a call from the vehicle 10 to the vehicle 11, the control device 300 fixes the first transmitter/receiver to the transmitter/receiver f2. The other party's vehicle 11 detects with the control device 300 that the frequency of the transmitted radio wave is [, and fixes it to the transmission r2 reception r of the first transceiver, and a conversation as shown in FIG. 2 is established. .
また、中継をお願いする場合には、副送受信機の操作器
２０８を操作して、中継依頼信号を主通信装置を介して
車両１１に向けて発射する。車両１１では、制御装置３

、中継依頼信号を解読して第２の送受信機の送信「３、
受信ｆ６に固定して電波を発射する。車両１２の制御装
置３００は車両１１からの電波がｒ、であると検出して
第１の送受信機は送信ｆ、受信ｆ、に固定する。When requesting a relay, the user operates the controller 208 of the sub-transmitter/receiver to send a relay request signal to the vehicle 11 via the main communication device. In the vehicle 11, the control device 3
00, the first transceiver fixes transmission r2 reception f1, decodes the relay request signal, and transmits "3,
Fixed to receive f6 and emit radio waves. The control device 300 of the vehicle 12 detects that the radio wave from the vehicle 11 is r, and the first transceiver is fixed to transmit f and receive f.
よって車両１０と車両１２との通信が車両１１を介して
第３図に示す通話が成立する。Therefore, the communication between the vehicle 10 and the vehicle 12 is established via the vehicle 11 as shown in FIG.
