INFORMATION PROCESSING DEVICE AND INFORMATION PROCESSING METHOD

An information processing device comprises a communication unit (100) that performs data communication with another vehicle (B) present in a periphery of a host vehicle (A), and a controller (110) that controls the data communication performed by the communication unit (100). The controller (110) identifies a designated moving body, which is the other vehicle (B) for which a quality of communication with the host vehicle (A) does not satisfy a predetermined standard. The controller (110) controls directivity related to wireless communication performed by the communication unit (100) based on a relative positional relationship between a first future position where the host vehicle (A) will travel in the future and a second future position where the designated moving body will travel in the future.
