  • Publication number: 20200172097
    Abstract: A server device includes: a server communication unit configured to communicate with a vehicle, and receive fallen object avoidance information from the vehicle, the fallen object avoidance information including position information on a fallen object and information indicating whether an avoidance operation was performed by the vehicle for the fallen object; and a server control unit configured to determine, for the same fallen object that is present at the same position, whether the same fallen object should be avoided based on the fallen object avoidance information, and notify a first following vehicle that the same fallen object should be avoided when the server control unit determines that the same fallen object should be avoided, the first following vehicle being a vehicle that is traveling within a predetermined range behind the same fallen object.

  • Patent number: 10460598
    Abstract: A driving action classifying apparatus has a driving-action-symbol acquiring unit configured to acquire position information on a vehicle and driving action symbols, which are data obtained by converting driving actions of the vehicle into symbols; and a tendency symbolizing unit configured to collect the driving action symbols corresponding to a same or similar place acquired from a plurality of vehicles and generate driving tendency symbols, which are data obtained by converting into a symbol a frequency distribution of the driving action symbols.

  • Patent number: 10089867
    Abstract: A turning value corrector corrects turning values contained in multiple pieces of travel history information. A reference turning value calculator uses multiple turning values that have been associated with the same calculation point to calculate a reference turning value. An anomalous travel location detector calculates the divergence from the reference turning value for each piece of travel history information subjected to detection of an anomalous travel location. Locations for which the deviation from the reference turning value is large are detected as anomalous travel locations.

  • Patent number: 9643649
    Abstract: A driving support apparatus includes: a travel possible region detecting device configured to detect a travel possible region of a vehicle; a travel controller configured to carry out locus control based on a target locus; and a controller configured to decide a road center of a curve, which is located forward of a traveling direction by a pre-read distance which is set according to a vehicle speed of the vehicle from a driver's own vehicle position of the vehicle, as a reference point, at the time the curve exists forward of the traveling direction, decide a position offset from the reference point to inside of the curve by a lateral displacement which is set according to a radius of curvature of the curve at the reference point, as a target point, and create the target locus so as to pass through the driver's own vehicle position and the target point.
