  • Publication number: 20240300524
    Abstract: A vehicle control device includes a recognizer configured to recognize a surrounding situation of a vehicle, a driving controller configured to control steering, acceleration, and deceleration of the vehicle independently of an operation of a driver of the vehicle, and a mode decider configured to decide on a driving mode of the vehicle as one of a plurality of driving modes including a first driving mode and a second driving mode. The recognizer recognizes an available travel lane in the same direction as the vehicle located inside of a reference range. The mode decider changes the driving mode of the vehicle from the second driving mode to the first driving mode on the basis of the number of lanes recognized by the recognizer when the driving mode of the vehicle is the second driving mode.

  • Patent number: 11941868
    Abstract: An inference apparatus provides target data to multiple inference models to cause the inference models each derived from local learning data obtained in a different environment to perform predetermined inference to obtain an inference result from each of the inference models. The inference apparatus determines the value of each combining parameter using environment data, weights the inference result from each of the inference models using the determined value of each combining parameter, and combines the weighted inference result from each inference model together to generate an inference result in a target environment.

  • Publication number: 20220269252
    Abstract: It is provided a method (and corresponding apparatuses, computer programs, and medium) for determining whether an item being processed is defective or non-defective, the method including a step of determining, by a local neural network and on the basis of sensing measurements performed on an item while the item is being processed, a local classification result indicating whether the item is defective or non-defective. It is determined a confidence index indicating a level of confidence that the local classification result is correct. Then, in response to the confidence index being below a given threshold, it is determined, by a central neural network and on the basis of the sensing measurements, a central classification result indicating whether the item is defective or non-defective, wherein the local neural network has less computational resources than the central neural network.

  • Patent number: 11055863
    Abstract: A control device assumes that observation light observed by an imaging device is composite light of primary reflection light and secondary reflection light. The control device acquires three or more samples of a brightness amplitude value of the observation light, calculates a phase error caused by the secondary reflection light using these samples, calculates a corrected phase value by correcting a phase value of the observation light using the phase error, and calculates a three-dimensional position of the measurement point on the measurement object based on the corrected phase value.
