Communication control device
First Claim
1. A communication control device for vehicle comprising:
- a dedicated short range communication processing unit that executes a direct vehicle-to-vehicle communication, which is a direct vehicle-to-vehicle communication without passing through a wide area communication network, with a peripheral vehicle disposed around the vehicle in cooperation with a dedicated short range communication module for executing a direct wireless communication with an external device without passing through the wide area communication network;
a wide area communication processing unit that executes an indirect vehicle-to-vehicle communication, which is an indirect vehicle-to-vehicle communication with passing through the wide area communication network, with the peripheral vehicle in cooperation with a wide area communication module for wirelessly communicating with the external device via the wide area communication network; and
a vehicle data generation unit that generates vehicle data indicating a traveling state of the vehicle based on a detection result of a sensor mounted on the vehicle, wherein;
the dedicated short range communication processing unit wirelessly transmits a communication packet including the vehicle data from the dedicated short range communication module in a predetermined dedicated short range transmission cycle; and
the wide area communication processing unit performs a process of transmitting the communication packet including the vehicle data to the peripheral vehicle via the wide area communication module and the wide area communication network in a predetermined wide range transmission cycle;
the communication control device further comprising;
a peripheral vehicle determination unit that determines whether an other vehicle corresponding to the peripheral vehicle is disposed within a predetermined area determined with reference to a position of the vehicle, based on the vehicle data acquired by the dedicated short range communication processing unit and the wide area communication processing unit, wherein;
the wide area communication processing unit selects a predetermined first wide area transmission cycle longer than the dedicated short range transmission cycle as the wide area transmission cycle when the peripheral vehicle determination unit determines that no other vehicle is disposed within the predetermined area; and
the wide area communication processing unit selects a predetermined second wide area transmission cycle equal to or shorter than the dedicated short range transmission cycle as the wide area transmission cycle when the peripheral vehicle determination unit determines that the other vehicle is disposed within the predetermined area.

Abstract
A vehicular communication control device includes: a dedicated short range communication processor executing a direct vehicle-to-vehicle communication; a wide area communication processor executing an indirect vehicle-to-vehicle communication; a vehicle data generator, and a peripheral vehicle determination unit determining whether another vehicle is disposed within a predetermined area. The dedicated short range communication processor wirelessly transmits a communication packet including vehicle data in a dedicated short range transmission cycle. The wide area communication processor transmits the communication packet including the vehicle data to a peripheral vehicle in a wide range transmission cycle. The wide area communication processor: selects a first wide area transmission cycle longer than the dedicated short range transmission cycle when no other vehicle is disposed within the area; and selects a second wide area transmission cycle equal to or shorter than the dedicated short range transmission cycle when the other vehicle is disposed within the area.
