  • Patent number: 11068735
    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.

  • Patent number: 11042759
    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.

  • Publication number: 20200117921
    Abstract: In an apparatus for recognizing a road shape of a travel route of a first vehicle, a surrounding environment recognizer repeatedly recognizes, as surroundings information, at least shapes of roadside objects or travel histories of second vehicles that are vehicles other than the first vehicle, located around the first vehicle in a travel direction of the first vehicle. A sequence-of-point estimator repeatedly estimates, using the surroundings information, a reference line connecting a sequence of points that represent the road shape of the travel route in the travel direction of the first vehicle. A first lane boundary setter repeatedly sets a first lane boundary that is a boundary of a lane of the first vehicle, located at a first distance from the reference line to a respective one of the left and the right of the first vehicle in a vehicle-widthwise direction of the first vehicle.
