Abstract: A road shape recognizer includes a peripheral information recognizer that recognizes at least two items of peripheral information based on an output of a periphery detector. A reliability assigner assigns a reliability level to each of the peripheral information. A point sequence generator generates and places a point sequence representing a shape of a road on which the own vehicle travels, based on at least two items of peripheral information and the reliability level. The point sequence generator generates and places a point sequence by generating and placing points one by one toward a distant place from a point located at a prescribed relative position to the own vehicle. The point sequence generator generates and places the next point corresponding to an amount of change in shape and a position of a point generated and placed at the end of the point sequence. The amount of change in shape is represented by the peripheral information and determined per section having a prescribed distance.

Abstract: A road recognition device includes a surroundings recognition section recognizing, as surroundings information, at least one of a shape of a roadside object and a travel history of another vehicle, a reliability setting section setting reliability of the surroundings information, a reference line setting section preferentially using surroundings information having higher reliability to determine a reference line of an own lane, and an output section outputting the reference line. When a direction indicator is in operation, the reliability setting section sets reliability of the surroundings information for a direction opposite to a direction indicated by the direction indicator so as to be lower. When the direction indicator is in operation, and the vehicle is traveling in a lane-change prohibition section, the reliability setting section sets reliability of the surroundings information including at least one of the shape of the roadside object and the travel history so as to be lower.

Abstract: A reliability calculation apparatus calculates a reliability of a recognized object that is recognized as being present on a route on which a vehicle travels. The reliability of the recognized object is used for driving control of the vehicle. In the reliability calculation apparatus, a provisional reliability calculating unit determines a feature quantity of each of a plurality of recognized objects, selects a plurality of pairs of recognized objects from the plurality of recognized objects, determines a difference in feature quantity of each pair of recognized objects, and calculates a reliability that decreases as the difference in feature quantity increases as a provisional reliability of each pair of recognized objects. An integrated reliability calculating unit calculates an integrated reliability of each recognized object from the provisional reliabilities of the plurality of pairs of recognized objects.

Abstract: In an apparatus for controlling travel of an own vehicle which is a vehicle carrying the apparatus, an information acquirer is configured to acquire information regarding a target around the own vehicle from a target detector. A controller is configured to, if determining, using the target information acquired by the information acquirer, that if travel of the own vehicle is continued in accordance with a collision avoidance trajectory determined to avoid a collision with an object located on a roadway ahead of the own vehicle, the own vehicle is likely to collide with the object or another object, change a setting of a driving state of the own vehicle so as to avoid or reduce a likelihood of the collision.

Abstract: A driving assistance device includes an object detection unit configured to detect a hazardous object that is capable of causing an accident in a path of a subject vehicle and surroundings of the path, and an evasive driving detection unit configured to detect features of driver's evasive driving, in which a driver of the subject vehicle performs driving operations to avoid danger of the accident when the subject vehicle approaches and passes by the hazardous object detected by the object detection unit. The driving assistance device further includes a concentration level determination unit configured to determine a concentration level of the driver on driving based on the features of driver's evasive driving detected by the evasive driving detection unit, and a notification unit configured to, when the concentration level determination unit determines that the concentration level of the driver on driving is dropping, provide a notification to encourage safe driving.

Abstract: An evacuation running assistance system includes a road shoulder evacuation possibility determiner to determine if an own vehicle can be evacuated to a road shoulder; an own vehicle situation determiner to determine a current situation of an own vehicle in accordance with a time limit and the road shoulder evacuation possibility, a controller to control an own vehicle in accordance with the situation of the own vehicle; and a road shoulder evacuation possibility road determiner to acquire evacuation space information from a past running history of the own vehicle. The own vehicle situation determiner determines that the own vehicle is in the situation to be controlled to perform the on-lane stopping when the road shoulder evacuation possibility road determiner does not determine within the provisional time that the evacuation of the own vehicle to the road shoulder is possible.

Abstract: A roadside object recognition apparatus recognizes a roadside object that is present on a travel route on which an own vehicle travels. The roadside object is used for driving control of the vehicle. In the roadside object recognition apparatus, a reflection point acquiring unit acquires, using a radar that emits electromagnetic waves, a reflection-point group of reflection points of the electromagnetic waves reflected by an object that is present on the travel route. An image acquiring unit acquires an image of the travel route using a camera. A reflection point correcting unit corrects the reflection-point group by removing an erroneous reflection point that is determined to be highly likely not to be a reflection point of a roadside object from the reflection-point group through image processing of the image. A shape recognizing unit recognizes a shape of the roadside object using the corrected reflection-point group.
