  • Publication number: 20210237757
    Abstract: An information processing device acquires question information. The information processing device acquires vehicle state information representing a state of the vehicle. The information processing device acquires answer information in response to the question information, the answer information including an image for display. The information processing device, in a case in which the vehicle state information represents that the vehicle is traveling, stores the answer information in a storage. The information processing device, in a case in which the information processing device acquires vehicle state information representing that the vehicle is stopped, outputs the answer information stored in the storage.

  • Publication number: 20210232414
    Abstract: An agent device receives input information that is input by the user, in a case in which the input information is a question from the user, executes inference processing on the input information to infer an intent of the question in order to acquire a response to the question based on the intent, in a case in which a plurality of the responses are acquired, provides the notification device with option information that includes the plurality of responses as options, in a case in which new input information is received, determines whether the new input information is information requiring the inference processing or is selection information relating to a selection result from selection of the options, and in a case in which the new input information is the selection information, provides the notification device with response information regarding the response associated with the selection result without executing the inference processing.

  • Publication number: 20210209316
    Abstract: An agent system includes a first memory and a first processor coupled to the first memory. The first processor analyzes contents of a verbal question, and caries out pre-processing that replaces vocabulary, which is used in the contents of the question, with homogenized vocabulary, and generates response information based on results of analysis. In a case in which there exists substitution vocabulary that has replaced original vocabulary in the pre-processing, the first processor changes the response information such that it can be recognized that the substitution vocabulary in the response information is synonymous with the original vocabulary, and outputs the response information.

  • Publication number: 20210193129
    Abstract: In cases in which a confidence score of an inferred intent label is a predetermined threshold or less, an intent inference section searches for whether or not wording pertaining to a location, such as “on the door”, is present in a question. In cases in which a word relating to a location is present, the intent inference section consults individual function identification data associated with OM item codes in order to find intent labels including individual functions relevant to the location (such as “door”). In cases in which an intent label including an individual function relevant to the “door” is found, an OMA interaction control section consults QA data to find and acquire associated response information based on the found intent label and the OM item code, and notifies a HMI interaction control section of such response information.

  • Patent number: 9490687
    Abstract: A rotational difference is generated between a first and a second rotor and a third rotor, which causes an induced current to flow in a first rotor winding. This causes a torque to act between the first rotor and the third rotor. The rotary magnetic field generated by the induced current flowing through a second rotor winding interacts with a second stator, which in turn generates an induced electromotive force in a second stator winding. The induced electromotive force is applied via a phase adjustment circuit to a first stator winding, which generates a rotary magnetic field and causes a torque to act between the first stator and the third rotor. The rotary magnetic field generated by the second rotor winding and the induced current flowing in the second stator winding causes a torque to act between the second stator and the second rotor.
