  • Patent number: 11447121
    Abstract: When the state of charge of a battery is greater than or equal to a lower limit value and less than or equal to an upper limit value, an electronic control unit calculates a charging electric energy transferred between a motor-generator and the battery such that the battery is neither charged nor discharged. When the state of charge is less than the lower limit value, a required torque of the engine is calculated based on the charging electric energy, a power consumption of an auxiliary device, and a driving torque. When the state of charge is greater than or equal to the lower limit value and less than or equal to the upper limit value, the required torque is calculated based on the charging electric energy and the driving torque, without taking the power consumption into consideration.

  • Patent number: 11379536
    Abstract: Even when there are many candidates for a linked entity, accuracy of estimating an entity related to a term that appears on given writing is improved. A classification device stores a first model generated by using a corpus including pieces of first writing related to predetermined entities, and a second model generated by using a corpus including the pieces of first writing. Features of terms included in the first writing are acquired from the first model. Features of the pieces of first writing are acquired from the second model. The classification device causes the first model to output first information indicating entities indicated by terms, which has similarity in a feature to a second term included in second writing, among first terms indicating the predetermined entities. The classification device causes the second model to output second information indicating entities related to pieces of writing, which has similarity in a feature to the second writing, among the pieces of first writing.
