  • Control apparatus
    Patent number: 9951865
    Abstract: An automatic transmission of this invention includes a plurality of engaging mechanisms, and the plurality of engaging mechanisms include a mechanical engaging mechanism that functions as a brake. The mechanical engaging mechanism can switch a rotational element between a first state in which rotation is restricted only in one direction and a second state in which rotation is restricted in both directions. When switching from the first state to the second state, engagement control is started in advance for at least one of the plurality of engaging mechanisms to be set in an engaging state.
    Type: Grant

  • Control apparatus for an automatic transmission
    Patent number: 9951864
    Abstract: This invention provides a control apparatus for an automatic transmission, which includes a plurality of engaging mechanisms. The plurality of engaging mechanisms includes a mechanical engaging mechanism configured to function as a brake. The mechanical engaging mechanism can be switched between a first state in which rotation of a rotational element is restricted only in one direction and a second state in which the rotation is restricted in both directions. When switching from the first state to the second state, the control apparatus executes engagement control to set a plurality of hydraulic friction engaging mechanisms in an engaging state. Control to set a predetermined hydraulic friction engaging mechanism in a half-engaging state and brake an output member can be executed in parallel to the engagement control.
