  • Patent number: 11087146
    Abstract: A lane-line recognizing apparatus includes an acquiring unit, an extractor, and an identifier including a storage and an estimator. The acquiring unit acquires a traveling environment information on a traveling environment in front of an own vehicle. The extractor extracts feature quantities of lane-line components of lane lines from each frame image on a basis of the traveling environment information acquired by the acquiring unit. The identifier identifies the lane lines on the basis of the feature quantities extracted by the extractor. The storage stores the feature quantities extracted by the extractor. When the feature quantities are extracted again after a transition from a condition where the lane lines are identifiable to a condition where the lane lines are unidentifiable, the estimator estimates, on the basis of the feature quantities stored in the storage, the lane lines after the transition to the condition where the lane lines are unidentifiable.

  • Patent number: 11010618
    Abstract: An apparatus for identifying a line marking on a road surface. In the apparatus, an extractor extracts a paint candidate that is a candidate for road surface paint used to identify a line marking in an image captured by a camera mounted on a vehicle to capture an image of an area including a road surface ahead of the vehicle. A determiner determines whether or not the paint candidate has at least one predefined flare feature. A line marking identifier identifies a line marking using the paint candidate which meets an identification condition used to identify a line marking. The line marking identifier sets the identification condition to be more stringent for a flare paint candidate that is the paint candidate determined by the determiner to have the at least one predefined flare feature than for the paint candidate determined by the determiner to have no predefined flare feature.

  • Publication number: 20210132153
    Abstract: A battery management system includes a control device and a storage. The storage stores at least one trained neural network. The trained neural network includes an input layer that accepts input data that represents a numeric value for each pixel in an image where a prescribed CCV waveform (a CCV charging waveform or a CCV discharging waveform) of a secondary battery is drawn in a region constituted of a predetermined number of pixels, and when input data is input to the input layer, the trained neural network outputs a full charge capacity of the secondary battery. The control device estimates the full charge capacity of a target battery by inputting input data obtained for the target battery into the input layer of the trained neural network.

  • Patent number: 10635911
    Abstract: In an apparatus for recognizing a travel lane of a vehicle, a deviation determiner is configured to, if two or more shape change points are extracted by a shape change point extractor and the second derivative value of curvature of an extracted boundary line at at least one of the two or more shape change points is inverted in sign, determine whether or not the extracted boundary line and an estimated boundary line estimated from travel lane parameters estimated by a travel lane parameter estimator are deviating from each other beyond a predetermined allowable range. A driving aid is configured to, if it is determined that the extracted boundary line and the estimated boundary line are deviating from each other beyond the predetermined allowable range, perform control upon deviation to prevent occurrence of undesirable situations that may be caused by deviation between the extracted boundary line and the estimated boundary line.
