Abstract: A communication control device is configured to select a communication frequency band for communicating between a vehicle and an external base station when starting communication between the vehicle and the external base station. In selecting the communication frequency band, the communication control device measures or determines the amount of electromagnetic noise in each frequency band inside the cockpit module, and including the communication frequency band. Then, the communication control device identifies an electrical device that is a source of the electromagnetic noise based on frequency bands in which the amount of electromagnetic noise is greater than or equal to a predetermined value. The communication control device sets an operating clock frequency of the electrical device to a first frequency band that differs from the communication frequency band.

Abstract: A vehicle mounted antenna is inside a cockpit module. The vehicle mounted antenna is positioned above a duct in the cockpit module at least a certain distance from an on-board device that is a source of noise and that is positioned below the duct. The duct is installed via a metal bracket that has a higher heat conductivity than the vehicle mounted antenna.

Abstract: 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 communication unit has a normal mode, and a directivity mode in which directivity of wireless communication is controlled to a greater extent than in the normal mode so that data communication can be performed with another vehicle at a position at which data communication cannot be performed in the normal mode. The controller receives server data from a server that includes information pertaining to the other vehicle present at the position at which data communication cannot be performed in the normal mode. The controller controls the directivity of the wireless communication of the communication unit based on the information pertaining to the other vehicle from the server.

Abstract: A communication control device is configured to select a communication frequency band for communicating between a vehicle and an external base station when starting communication between the vehicle and the external base station. In selecting the communication frequency band, the communication control device measures or determines the amount of electromagnetic noise in each frequency band inside the cockpit module. Then, the communication control device changes the communication frequency band based on the amount of electromagnetic noise, and communicates with the external base station using the changed communication frequency band.

Abstract: An information processing device includes a communication unit and a controller. The communication unit performs data communication with another vehicle present in an area around a host vehicle. The controller controls the data communication performed by the communication unit. Based on an amount of transition in frequency due to a Doppler shift corresponding to a relative speed of the other vehicle in relation to the host vehicle, the controller extracts, from among a plurality of the other vehicles, a designated moving body with which the communication unit is to perform the data communication. The controller initiates the data communication with the designated moving body.

Abstract: 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.

Abstract: 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 specifies each second other vehicle for which a quality of communication with the host vehicle does not satisfy a prescribed standard as a designated moving body. The controller identifies a relative position relative to the host vehicle, and a reception power of radio waves received from the designated moving body, for each designated moving body. The controller controls directivity related to wireless communication performed by the communication unit based on the relative position and reception power for each other vehicle.
