Abstract: A communication control device used in a terminal device that performs mobile communication is provided. The communication control device controls a communication module of the terminal device to perform direct communication with a different terminal device not via a base station. The communication control device manages whether the communication module is in a search mode or a communication mode, and determines, using information managed, whether a transmission timing of a signal from the communication module determined in accordance with occurrence timing of a transmission event overlaps the search mode. When determining that the transmission timing overlaps the search mode, the communication control device shifts the transmission timing out of the time duration of the search mode.

Abstract: A velocity estimation device including an acceleration sensor and a yaw rate sensor is provided. The velocity estimation device determines an initial velocity value of a mobile object based on a velocity estimation expression, an integrated value of acceleration detected by the acceleration sensor, and a relative azimuth calculated from detected yaw rates. The velocity estimation device estimates the velocity of the mobile object based on the initial velocity value and the integrated value of acceleration. In the velocity estimation expression, a magnitude of the velocity vector is constrained by the velocity of the mobile object and a time variation of a direction of the velocity vector is constrained by a time variation of the azimuth of the mobile object in the traveling direction.

Abstract: A wireless communication device includes a short range receiving unit, a channel control unit for controlling a setting of a reception channel of the short range receiving unit to a control channel or a service channel, and an execution service determination unit. The channel control unit sets the reception channel as the control channel during a control channel time frame, and maintains the reception channel as the control channel during an extension time frame even after the short range receiving unit receives the service start information. The execution service determination unit performs an execution service determination process for determining, as an execution service, a service having the highest priority out of the services indicated by the service start information received by the short range receiving unit while the reception channel is set as the control channel by the channel control unit.

Abstract: An in-vehicle unit, which is used in each of host vehicles including a subject vehicle and nearby vehicles, includes an inter-vehicle communicator to perform inter-vehicle communication. The in-vehicle unit in the subject vehicle includes a criterion value setting section and a different-unit anomaly detection section. The criterion value setting section receives a different-unit installation state index via the inter-vehicle communicator and sets successively a criterion value of an installation state index from the received different-unit installation state index specified based on an output value from a sensor instrument that successively outputs an output value corresponding to an installation state of the in-vehicle unit on each nearby vehicle. The different-unit anomaly detection section detects an abnormal installation state of the in-vehicle unit on a target nearby vehicle by comparing the criterion value with the different-unit installation state index received from the target nearby vehicle.
