  • Publication number: 20240401683
    Abstract: A rotary electric machine, a transmission, and a differential gear device are disposed coaxially. The transmission includes a first helical gear and a second helical gear that meshes with the first helical gear. A case includes a first case member including a stator support portion that supports a stator of the rotary electric machine, a second case member that is structured as a separate member from the first case member and forms a gear chamber that houses the transmission and the differential gear device, and a support member that supports the first helical gear in an axial direction. The support member rotatably supports a rotor of the rotary electric machine via a rotor bearing, and is fixed to the second case member.

  • Publication number: 20240317212
    Abstract: A control device for a hybrid vehicle determines whether an EGR valve has an opening failure, and performs a pre-operation in which the engine is operated at a load smaller than a load in a series mode for a certain period of time while the vehicle is driven by a motor immediately before switching from an EV mode to the series mode. The pre-operation has a normal pre-mode in which the engine is operated at a first load when it is determined that the EGR valve does not have an opening failure, and a small failure pre-mode and a large failure pre-mode in which the engine is operated at a second load larger than the first load when it is determined that the EGR valve has the opening failure.

  • Patent number: 12071908
    Abstract: An upstream integrated value is an integrated value of a difference obtained by subtracting an upstream gas temperature at a starting point in time of integration from the upstream gas temperature after starting of the internal combustion engine. A downstream integrated value is an integrated value of a difference obtained by subtracting a downstream gas temperature at the starting point in time of the integration from the downstream gas temperature after the starting of the internal combustion engine. An anomaly diagnosing process obtains an anomaly determination result indicating that the exhaust purification device is in a removed state when a deviation between the upstream integrated value and the downstream integrated value is smaller than a reference level. The determination threshold is higher than a dew point.

  • Patent number: 11380817
    Abstract: A method for manufacturing a light-emitting device includes preparing an intermediate product; the product includes a light-emitting element provided with paired electrodes at a first surface and a first covering member covering the light-emitting element such that portions of surfaces of the paired electrodes are exposed. A metal paste layer is formed, continuously covering the exposed portion of the paired electrodes and the first covering member. Paired wirings are formed for preventing the paired electrodes from being short-circuited. The metal paste layer on the paired electrodes and the metal paste layer on the first covering member are irradiated with laser light to remove the metal paste layer between the paired electrodes and a portion of the metal paste layer on the first covering member.
