Patent attributes
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.
