    摘要: A lubricating structure is for a hybrid vehicle that includes an engine, a first motor, and a second motor as driving force sources. The lubricating structure includes a planetary gear mechanism, a brake mechanism, an oil pump, and a first oil supply mechanism. The brake mechanism selectively fixes a carrier of the planetary gear mechanism by stopping rotation of the carrier. The oil pump is driven by a predetermined power to generate a hydraulic pressure of oil in a state in which the rotation of the carrier is stopped by the brake mechanism. The first oil supply mechanism feeds the oil to an axis portion of each of pinion gears of the planetary gear mechanism by the oil pump generating the hydraulic pressure.

    摘要: A control device for a vehicle, the vehicle includes a transmission provided in a power transmission path between a drive power source and drive wheels. The control device includes an electronic control unit configured to i) shift the transmission according to traveling conditions, ii) switch a driving mode for running the vehicle between autonomous driving under autonomous driving control, and manual driving based on driving operation of a driver, and iii) shift the transmission such that a shift time required for shifting of the transmission during the manual driving is shorter than a shift time required for shifting of the transmission during the autonomous driving.

    摘要: A soundproofing device for a transmission according to the present disclosure is provided to transmit the power of one or more prime movers (for example, internal combustion engine and electric motor). The soundproofing device includes a Helmholtz resonator including: a wall that forms a Helmholtz resonance chamber; and an opening formed in the wall so as to cause the Helmholtz resonance chamber to communicate with the outside of the Helmholtz resonance chamber. The wall includes a transmission case that accommodates the transmission and a housing of a component mounted on the transmission (for example, PCU housing). The Helmholtz resonance chamber is formed between the transmission case and the housing.
