Abstract: A wireless communication device used in a vehicle is provided, includes a communicator that performs wireless communication with a service provider terminal, a vehicle condition acquirer that acquires a condition of the vehicle, a correspondence storage that stores a correspondence of what type of service is available under what condition of the vehicle, and an availability determiner that determines whether the service provided by the service provider terminal is available under the condition of the vehicle acquired by the vehicle condition acquirer, based on service type information included received by the communicator, the condition of the vehicle acquired by the vehicle condition acquirer, and the correspondence stored in the correspondence storage. When the availability determiner determines that the service is unavailable, the communicator does not open a service channel designated by the service provider terminal.

Abstract: A communication device includes: a time zone determiner section that identifies a switching point of time of communication time zones based on a clock time and determines whether the communication time zones are switched based on the clock time and the switching point of time; a channel switch section that designates a communication-target channel by switching the communication time zones at the identified switching point of time; a transmission processor section that performs a data transmission using the communication-target channel designated, and prohibits data transmission from being performed for a predetermined transmission prohibition duration time before and after the switching point of time; an error assessor section that assesses an error amount that is a degree of an error of the clock time against the reference clock time; and a transmission prohibition-time adjuster section that increases the transmission prohibition duration time as the error amount increases.

Abstract: A vehicular communication terminal is provided. A reception strength acquirer acquires a reception strength of a signal transmitted from a service provider terminal. When the vehicle communication terminal receives a signal corresponding to service initiation information from the service provider terminal, a transmission terminal determiner determines whether a transmission source of the signal is the service provider terminal that provides a service targeted for the vehicular communication terminal, based on at least either one of magnitude of the reception strength of the received signal acquired by the reception strength acquirer and a degree of reception strength change in signal received from the service provider terminal serving as a transmission source of the received signal.

Abstract: A positioning device receives positioning signals from multiple positioning satellites respectively provided by multiple positioning systems, selects one or more use systems to be used in a positioning calculation processing among the multiple positioning systems based on a determination of whether a surrounding environment is an environment in which a multipath is likely to occur, and performs the positioning calculation processing by using the positioning signals from the positioning satellites provided by the positioning systems selected as the use systems.

Abstract: A mobile communication system is provided. A service provider terminal distributes service initiation information by using a control channel. Upon receipt of the service initiation information, an onboard terminal determines, based on service type information included in the service initiation information and available service type stored in the onboard terminal, whether the service provided by the service provider terminal is available to the onboard terminal itself. The onboard terminal determines, based on target terminal information included in the service initiation information and determination information acquired by the onboard terminal, whether the onboard terminal itself is an onboard terminal targeted for the service.

Abstract: A vehicular communication device is provided. The vehicular communication device includes a reception section that receives, from a periphery vehicle equipped with a narrow area communicator, a communication performance index representing performance of the narrow area communicator, and controller. The controller includes a reference value setup section that successively settles a reference value as a criterion for the communication performance index based on the communication performance indexes received from multiple periphery vehicles, an acquisition section that acquires the communication performance index for a targeted narrow area communicator serving as the narrow area communicator targeted at anomaly determination, and an anomaly determination section that determines an anomaly of the targeted narrow area communicator based on comparison between the reference value settled by the reference value setup section and the communication performance index acquired by the acquisition section for the targeted narrow area communicator.

Abstract: In-vehicle units are on host vehicles including a subject vehicle and at least one nearby vehicle. Each in-vehicle unit transmits and receives information using inter-vehicle communication, acquires information indicating state of a control system controlling operation of each in-vehicle unit, generates an index data-item including an index value indicating state of the control system based on the acquired information, and transmits the generated index data-item using inter-vehicle communication. A subject in-vehicle unit in the subject vehicle includes: a communication processing section acquiring an index data-item from the nearby vehicle; a determination criterion specification section successively specifying a self-unit determination criterion being a determination criterion determining whether the control system in the subject in-vehicle unit operates normally, based on the index data-item; and a self-unit diagnosis test section determining whether the control system in the subject in-vehicle unit operates normally by comparing the self-unit determination criterion with the index data-item in the subject in-vehicle unit.

Abstract: A mobile object communication system includes a mobile object side device, a service provision device performing a short range wireless communication with the mobile object side device to provide a service to the mobile object side device, and a wide area route provision unit performing a wide area communication with the mobile object side device to provide the service having the same contents as the service provided by the service provision device. The mobile object side device can perform both of the short range wireless communication and the wide area communication, and determines whether the short range wireless communication can be performed with the service provision device. When determining that the short range wireless communication cannot be performed, the service having the same contents is provided by performing the wide area communication with the wide area route provision unit.
