Information processing device and information processing method

An information processing device comprising:

• a communication unit including an antenna, the communication unit being configured to be mounted on a first moving body and to perform data communication with a second moving body present in a periphery of the first moving body;
• and
• a controller configured to control the data communication performed by the communication unit,
• the communication unit having operating modes configured to be switched between a directivity mode in which directivity of wireless communication can be controlled and a normal mode in which the wireless communication in a preset area is performed without controlling the directivity of the wireless communication,
• the controller being configured to
• refer to map information to evaluate whether or not a travel situation exists in which the second moving body that will affect future travel of the first moving body is present,
• switch the operating mode of the communication unit from the normal mode to the directivity mode when said travel situation is determined to exist, and subsequently identify a designated moving body that is the second moving body for which a current quality of communication with the first moving body does not satisfy a predetermined standard by controlling the directivity of the wireless communication performed by the communication unit in a sweeping fashion to scan the periphery of the first moving body,
• identify a first future position where the first moving body will travel in the future,
• identify a second future position where the designated moving body will travel in the future, and
• control the directivity of the wireless communication performed by the communication unit based on a relative positional relationship between the first future position and the second future position.
