Abstract: A vehicle control apparatus acquires a position of an other vehicle that is present ahead of the own vehicle in its traveling direction, and uses the acquired position of the other vehicle to calculate a movement locus, which is a past path of the other vehicle. The vehicle control device calculates a lateral movement amount of the movement locus in a predetermined range in the traveling direction of the own vehicle, the lateral movement amount being an amount of change in position in a lateral direction which is a direction intersecting the traveling direction, and calculates an average value of the lateral movement amounts. The vehicle control apparatus excludes, from the movement loci, a movement locus having a lateral movement amount whose difference from the average value is larger than a predetermined value, and calculates the predicted path based on remaining movement loci.

Abstract: In a road type determination apparatus, an image information acquiring unit acquires image information in which an image of a travel road on which a vehicle is traveling is captured. A scene determining unit determines a traveling scene of the travel road based on the image information. An ordinary road likelihood calculating unit calculates an ordinary road likelihood that indicates that a type of the travel road of the vehicle is an ordinary road based on the traveling scene. A limited-access road likelihood calculating unit calculates a limited-access road likelihood that indicates that the type of the travel road of the vehicle is a limited-access road based on the traveling scene. A type determining unit determines the type of the travel road of the vehicle based on the ordinary road likelihood and the limited-access road likelihood.

Abstract: The start and end of the transmission of information is controlled by, depending on the situation, determining whether to stop transmitting position information on a vehicle-mounted terminal device transmitted by a vehicle-to-vehicle communication between a vehicle of interest and a surround vehicle and position information on a portable terminal device transmitted by a pedestrian-to-vehicle communication between the portable terminal device carried by a person who got off its own vehicle and a surround vehicle.

Abstract: A leading vehicle group 1 transmits divided data 71 and 72 obtained by dividing vehicle information 7. Data transfer vehicle groups 2 and 3 transfer the divided data 71 and 72 to a data composite vehicle group 4 and to following vehicle groups 5 and 6. The data composite vehicle group 4 transfers composite data 73 obtained by XORing the divided data 71 and 72 to the following vehicle groups 5 and 6. The following vehicle group 5 XORs the divided data 71 received from the data transfer vehicle group 2 with the composite data 73 received from the data composite vehicle group 4 to restore the unreceived divided data 72.
