Abstract: A vehicle onboard communication terminal in a mobile communication system that establishes vehicle-to-vehicle communication and road-to-vehicle communication by using a carrier wave and employs Carrier Sense Multiple Access/Collision Avoidance method includes: a reception processing portion that receives road-to-vehicle communication data transmitted from a roadside device and vehicle-to-vehicle communication data transmitted from a different vehicle onboard communication terminal; a transmission processing portion; a transmission control portion that controls an operation of the transmission processing portion and has a regular transmission mode and a passive transmission mode; and a determination portion. The transmission control portion detects usage of the carrier frequency when the transmission control portion is operating in the regular transmission mode. the transmission control portion stops the transmission of the vehicle-to-vehicle communication data and receives data addressed to the vehicle onboard communication terminal from the roadside device when the transmission control portion is operating in the passive transmission mode.

Abstract: In an electronic control apparatus, a wireless data control section includes a wireless data reception section that moves wireless data stored in a first wireless data storage unit to an intermediate wireless data storage unit, and a wireless data management section that moves the wireless data stored in the intermediate wireless data storage unit to a second wireless data storage unit. An in-vehicle data control section includes an in-vehicle data reception section that moves in-vehicle data stored in a first in-vehicle data storage unit to an intermediate in-vehicle data storage unit. Herein, a process performed by the wireless data reception section takes precedence over a process performed by the in-vehicle data reception section and over a process performed by the wireless data management section.
