Abstract: A self-localization estimation device includes: a map-information acquisition unit that acquires map information including lane information for specifying lanes in which vehicles are enabled to travel; a position calculation unit that calculates an own-vehicle absolute position being an absolute position of an own vehicle in response to navigation signals received from a plurality of navigation satellites, the position calculation unit including a self-location measurement unit, a vehicle-momentum measurement unit, and dead reckoning unit; and a position estimation unit that estimates, based on the map information and the own-vehicle absolute position, a corrected own-vehicle position being a corrected position of the own vehicle. The position estimation unit estimates the corrected own-vehicle position by superimposing a reliability of the map information and a reliability of the own-vehicle absolute position on each other.

Abstract: A vehicle behavior control apparatus mounted in a vehicle to control steering of the vehicle. A virtual road outline, which is an outline of a drivable road region where the vehicle will travel, is determined on the basis of detection results from a location sensor. The virtual road outline is reconstructed as a sequence of road segments, such as straight road segments, and right- and left-hand curved road segments. When a current road segment where the vehicle is currently present is a right- or left-hand curved road segment, a subsequent road segment where the vehicle will be present subsequently is tentatively set to a straight road segment until the vehicle reaches the subsequent road segment. The steering angle is controlled so that a virtual-road boundary distance is adapted to a proper distance from the vehicle to a boundary of the virtual road outline situated in front of the vehicle.

Abstract: A driving support apparatus derives position prediction data when T=Tn, which is when a predicted time Tn has elapsed from the present time, based on acquired map data, position data and speed data. Direction prediction data indicating a traveling direction of a vehicle 1 at the time T=Tn is derived based on acquired map data and derived position prediction data. A yaw angle which is an angle formed by a traveling direction D0 represented by e direction data and the traveling direction Dn represented by direction prediction data is derived. A target speed Vn of the vehicle is then derived.

Abstract: An automatic traveling control apparatus includes an automatic traveling control unit, a function determining unit, a first notifying unit, an abnormality detecting unit, and a second notifying unit. The automatic traveling control unit makes an own vehicle automatically travel along a route to a destination. The function determining unit determines whether or not the state of a function used for automatic traveling is normal. The first notifying unit gives notification of the state of the function determined by the function determining unit. The abnormality detecting unit detects an abnormality in the notification of the state of the function by the first notifying unit. The second notifying unit gives a characteristic notification set in advance, when the abnormality detecting unit detects an abnormality in the notification of the state of the function by the first notifying unit and the function determining unit determines that the state of the function is normal.

Abstract: An autonomous driving control apparatus installable in a vehicle includes a path determining section, an obstacle determining section that determines whether an obstacle on the planned driving path is a passage acceptable obstacle or a passage unacceptable obstacle, the passage acceptable obstacle being previously set as an obstacle that the vehicle is allowed to come into contact with while passing, the passage unacceptable obstacle being previously set as an obstacle that the vehicle is not allowed to come into contact with while passing, and a control instructing section that gives an instruction of control to a maneuver controller to perform at least one of controlling a speed of the vehicle and controlling a steering of the vehicle to control a maneuver of the vehicle. If the obstacle is determined to be the passage acceptable obstacle, the control instructing section gives an instruction of the control to pass over the obstacle.

Abstract: A vehicle behavior control apparatus disposed in a subject vehicle performs a steering angle control of the subject vehicle. The apparatus acquires lead vehicle information transmitted from a lead vehicle to determine a virtual shape of a road (i.e., a virtual road shape) based on a travel locus of the lead vehicle. A virtual road border distance is calculated as a distance from the subject vehicle to a road border of a virtual curve road positioned straight in front of the subject vehicle. The apparatus, calculates an appropriate turn radius for travel along the virtual curve road and, based on the appropriate turn radius, calculates an appropriate distance from the subject vehicle to the virtual road border positioned in front of the subject vehicle. A steering unit then controls a steering angle of the subject vehicle by maintaining the virtual road border distance with the appropriate distance.

Abstract: A self-localization estimation unit of a self-localization estimation device determines, based on mutual relationships between the in-lane position and the absolute position including the error, whether there is lane-relevant candidate information, the lane-relevant candidate information representing that one or more in-vehicle positions are each estimated to be in which of lanes identified by the lane information; and estimates, based on a result of the determination of whether there is lane-relevant candidate information, a localization of the own vehicle corresponding to the map information.

Abstract: An automatic driving proposal device or an automatic driving proposal method is used for a vehicle that selects either a state of an automatic driving or a state of a manual driving by an occupant. The automatic driving proposal device or the automatic driving proposal method performs a driving change request to the occupant in the state of the automatic driving, determines whether the automatic driving is possible in the state of the manual driving, calculates a calculation value corresponding to a distance or a prediction time or calculates a change index, and proposes the automatic driving to the occupant on a necessary condition of determining that the automatic driving is possible and also determining that the calculation value is higher than a threshold value or determining that the change index is lower than a threshold value.
