  • Publication number: 20170138465
    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.
