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