    Abstract: A supercharging system includes a waste gate valve and an ECU. The ECU is configured to: calculate a first parameter and a second parameter, each of which has a positive correlation with an intake air amount; obtain a first difference by subtracting a first boost pressure from a second boost pressure; obtain a second difference by subtracting the first parameter from the second parameter; obtain a quotient by dividing the first difference by the second difference; and determine that a malfunction occurs in the waste gate valve when the quotient is larger than a threshold value.

  • Publication number: 20190013010
    Abstract: To assign an appropriate pronunciation to a word or phrase having a unique pronunciation or a word or phrase having a pronunciation incorrectly used by a user, a terminal device divides a first word or phrase indicated by a first recognition result acquired from a speech recognition server into morphemes and assigns a pronunciation to each of the morphemes, and divides a second word or phrase indicated by a second recognition result acquired from a speech recognition module into morphemes. Further, the terminal device selects, for a morpheme having the same character string as that of any one of the morphemes forming the second word or phrase among the morphemes forming the first word or phrase, a pronunciation of the morpheme indicated by the second recognition result.
