  • Patent number: 11467277
    Abstract: An object recognition apparatus groups reflection points detected by a radar device, and recognizes an object around the own vehicle, based on a radar-based target detected using the grouped plurality of reflection points and an image-based target detected using an image captured by an image capturing device. The object recognition apparatus includes a reflection point acquiring unit that acquires reflection point information related to the grouped plurality of reflection points, and an object determining unit that determines that a plurality of objects have been detected as a single object by the radar device, based on the reflection point information acquired by the reflection point acquiring unit and the information on the image-based target, if the image-based target detected by the imaging device includes an image-only target not detected by the radar device.

  • Patent number: 11373533
    Abstract: A vehicle control apparatus acquires a position of an other vehicle that is present ahead of the own vehicle in its traveling direction, and uses the acquired position of the other vehicle to calculate a movement locus, which is a past path of the other vehicle. The vehicle control device calculates a lateral movement amount of the movement locus in a predetermined range in the traveling direction of the own vehicle, the lateral movement amount being an amount of change in position in a lateral direction which is a direction intersecting the traveling direction, and calculates an average value of the lateral movement amounts. The vehicle control apparatus excludes, from the movement loci, a movement locus having a lateral movement amount whose difference from the average value is larger than a predetermined value, and calculates the predicted path based on remaining movement loci.

  • Publication number: 20210357709
    Abstract: In an object determination apparatus, a same-object determiner is configured to make a same-object determination as to whether a first object ahead of a subject vehicle that is a vehicle carrying the object determination apparatus, detected by an electromagnetic wave sensor, and a second object ahead of the subject vehicle, detected by an image sensor, are the same object. A candidate-object identifier is configured to identify a candidate for the first object, between which and the second object the same-object determination is to be made, as a candidate object. A candidate-object selector is configured to, in response to there being a plurality of the candidate objects, preferentially select, from the plurality of candidate objects, a candidate object whose likelihood for the identified object type of the second object is higher than a predetermined likelihood threshold, as a candidate object to be subjected to the same-object determination.

  • Patent number: 11131769
    Abstract: An ECU as an object detection device and a radar device are mounted on a vehicle. The radar device acquires front-view images containing a detection-target object such as a preceding vehicle present within a predetermined area around the vehicle. The radar device recognizes the detection-target object in time series based on the acquired front-view images. The ECU realizes a preceding vehicle selection part, an irregular-detection detecting part and an association processing part. The selection part selects the object when a relationship between the object and the vehicle satisfies a predetermined condition. The detecting part detects occurrence of an irregular detection when a first object selected as the preceding vehicle and a second object not selected as the preceding vehicle are detected based on the object. The association processing part performs an association process of associating history of the first object to the second object when the irregular detection has occurred.

    Abstract: A vehicle recognition device includes: an acquisition section acquiring image information based on an image captured by a vehicle-mounted camera; a boundary line detection section detecting, based on the image information, boundary lines on both left and right sides demarcating vehicle traveling lanes; a vehicle detection section detecting position information on an object vehicle; and a recognition section recognizing lane-to-lane movement of the object vehicle between an own lane in which the subject vehicle is traveling and an adjacent lane. The recognition section recognizes the lane-to-lane movement based on a second boundary line of the boundary lines, a lane width between a first boundary line of the boundary lines and the second boundary line, and the position information on the object vehicle, the first boundary line dividing the own lane and the adjacent lane, the second boundary line being different from the first boundary line.

  • Patent number: 11003927
    Abstract: In a target recognition apparatus that recognizes a target in a periphery of an own vehicle, a radar target acquiring unit acquires, as a radar target, the target that is detected by transmission and reception of radar waves. An image target acquiring unit acquires, as an image target, the target that is included in a captured image captured by an imaging apparatus. A target recognizing unit recognizes, as a first target, one of a plurality of radar targets included in a predetermined area relative to the image target and recognizes, as a second target, at least one of the plurality of radar targets other than the first target. A sameness determining unit determines whether the first target and the second target are the same object.

  • Publication number: 20210129867
    Abstract: A vehicle control apparatus is mounted in a vehicle and controls the vehicle. The vehicle control apparatus detects an obstacle that is present inside a grade crossing that intersects a traveling course of the vehicle, using a detection result of a sensor that is mounted in the vehicle. The vehicle control apparatus identifies a position and size of the obstacle using a detection result of the vehicle control apparatus, and calculates a clearance in a direction that intersects the traveling course when the vehicle crosses the grade crossing, using the identified position and size of the obstacle. The vehicle control apparatus determines whether the vehicle is able to pass through the grade crossing based on the calculated clearance.
