  • Publication number: 20140190455
    Abstract: A hybrid drive having a hydraulic control device capable of hydraulically controlling a first clutch, a second clutch, and a continuously variable transmission using a hydraulic pressure generated by at least one of a mechanical oil pump and an electric oil pump. A control section is configured to execute a mechanical oil pump drive mode in which a command to start an internal combustion engine is provided to drive the mechanical oil pump via a first shaft using output rotation of the internal combustion engine during reverse travel in which reverse rotation is output from the rotary electric machine to rotate wheels in reverse via the second shaft, the second clutch, and the continuously variable transmission with the first clutch disengaged and with the second clutch engaged by providing a command to the hydraulic control device.

  • Patent number: 7582035
    Abstract: An automatic transmission is capable of shifting between multiple speeds by engaging and disengaging multiple frictional engagement devices including at least one clutch and one brake, and is capable of switching between a driving range and a non-driving range with operation of a shift lever, wherein a first brake is engaged to fix an intermediate rotary member to a transmission case in a non-driving range such as neutral range. Thus, rotation of a clutch from drag torque can be stopped and shock due to engagement of a brake can be prevented by engagement of the first brake in the non-driving range.
