Japanese Patent Laid-Open No. 2003-315070

However, according to the technique described in Patent Document 1, information distribution to a terminal device uniformly distributes the same information from one information providing system to a plurality of terminal devices. Therefore, there is a problem that optimal information cannot be distributed to the situation where the terminal device is placed, such as the position and time of the terminal device, or to the passengers of the automobile or the person who has the terminal device. In addition, although only the necessary information can be requested from the terminal device side to the information providing system, a great deal of time and effort is required to select only the necessary information from among the many information distributed. There is a problem that it is necessary.
In addition, since there is no mechanism capable of individually identifying much information to be distributed, there is a problem that it is not possible to easily select optimal information from a large number of information groups. In particular, since the driver must drive safely while the vehicle is traveling, there is a large operational restriction to receive necessary information, and a communication control device that takes this restriction into consideration is required.

  The present invention has been made in view of such problems, and an object of the present invention is to make it possible to accurately transmit only information that is individually required by users of individual vehicle-mounted devices. In particular, the present invention proposes a communication control device for an in-vehicle device that considers safe driving as much as possible in a moving body such as an automobile.
