Abstract: An object is to provide a rearward white line inference device, a target recognition device, and a method capable of inferring a rearward white line with high accuracy. A rearward white line inference device includes: a white line detection unit that detects a white line ahead of a host vehicle; an azimuth-relative-to-white-line generation unit that obtains an azimuth of the host vehicle relative to the white line every predetermined time interval based on a detection result of the white line detection unit; and a relative azimuth inference unit that infers a relative azimuth from the azimuth of the host vehicle at a certain point based on the azimuth of the host vehicle obtained by the azimuth-relative-to-white-line generation unit.

Abstract: A driving assistance device that recognizes a lane marking around an own vehicle with at least one sensor includes a lane marking detection unit that detects lane marking information from data acquired by the sensor, a lane marking type candidate estimation unit that recognizes a lane marking type from the detected lane marking information and calculates a likelihood of each lane marking type, a lane marking type branch point estimation unit that detects a lane marking type branch point that is a point at which a likelihood of the lane marking type changes with respect to an advancing direction of the own vehicle, and distinguishes regions before and after the lane marking type branch point as a first region and a second region, and a lane marking information integration unit that, in a case where a lane marking of the first region and a lane marking of the second region have the same lane marking type, integrates the lane marking of the first region and the lane marking of the second region into a continuously recognizable lane marking.

Abstract: A travel assistance device includes: a detection result storage unit that stores a detection result of an external sensor installed in a host vehicle; a moving object recognition unit that recognizes a surrounding moving object based on a detection result of the external sensor; a route storage unit that stores a route along which the host vehicle has moved based on vehicle information acquired by a vehicle sensor installed in the host vehicle; an initial stop position determination unit that determines an initial position at which the host vehicle has stopped before starting, based on the detection result stored in the detection result storage unit; and a vehicle control unit that stops the host vehicle based on a recognition result of the moving object recognition unit after the host vehicle starts from the initial position. The detection result storage unit stores at least the initial position and the detection result on the route. The vehicle control unit controls movement on the route from a stop position where the host vehicle is stopped to the initial position based on a detection result of the external sensor at a current position of the host vehicle and a detection result of the external sensor stored in the detection result storage unit.

Abstract: Provided is a sensor information processing device that processes the detection results of the plurality of external-environment sensors that recognize the lane marker that divides the lane and can identify the lane marker more accurately than before. A sensor information processing device 100 includes a storage device 102 that stores a past detection result De of an external-environment sensor 200 as time-series data, and a central processing unit 101 that identifies a lane marker on the basis of the time-series data. The central processing unit 101 determines that the new detection result De belongs to the existing lane marker or the new lane marker on the basis of the comparison between the new detection result De not included in the time-series data and the time-series data.
