Abstract: A self-location estimation device includes a landmark detection unit that detects a landmark from camera information, an association unit that associates the landmark detected by the landmark detection unit with a radar information group, a landmark sorting unit that performs sorting of the landmarks detected by the landmark detection unit based on the radar information groups associated with the landmarks by the association unit, and a positional relation calculation unit that calculates a positional relation between an own vehicle and the landmark employed by the landmark sorting unit, based on the radar information group associated with the landmark.

Abstract: In a localization apparatus for a vehicle, a landmark detector detects a landmark from camera information acquired from a camera mounted to the vehicle. An associator associates the landmark with a specific set of radar information by setting an error region in which the landmark may exist, selecting, from a radar observation point cluster formed of a set of radar observation points corresponding to a set of radar information acquired from a radar mounted to the vehicle, a radar observation point cluster formed of a set of radar observation points included in the error region, and associating the landmark with the specific set of radar information corresponding to the selected radar observation point cluster. A positional relationship calculator calculates a positional relationship between the landmark and the vehicle based on the specific set of radar information associated with the landmark.

Abstract: In a road information distribution system, a cloud server detects to road location where an abnormality is occurring based on vehicle location information of a plurality of vehicles or vehicle controlling amount of a plurality of vehicles, and transmits an abnormal road location to a vehicle before identifying a cause of the abnormality. The road information distribution system then notifies the abnormal road location to a driver of the vehicle when the vehicle approaches a predetermined distance from the abnormal road location.

Abstract: A route generation device includes: an autonomous route generator configured to generate, based on surrounding information around an own vehicle detected by a vehicle-mounted detector, an expected autonomous route along which the own vehicle is to travel; a map route acquirer configured to acquire an expected map route along which the own vehicle is to travel based on map data; and an integrated route generator configured to generate an integrated route using the autonomous route and the map route.

Abstract: An object detection device includes an azimuth sensor that measures an azimuth region of an object that is present around a vehicle, a plurality of distance sensors each of which measures a distance to the object, and an object determination section that calculates arcs of circles whose radii are the distances measured by the respective distance sensors and calculates intersection points of a tangent to adjacent ones of the arcs and the azimuth region measured by the azimuth sensor.
