Abstract:
A control apparatus of an automatic transmission, which includes a mechanical engaging mechanism functioning as a brake, includes a determination unit determining, when a selected gear is a lowest forward speed gear, and the mechanism is in a second state, whether to switch the mechanism to the first state, and a switching processing unit switching the mechanism to the first state based on a determination result. In the first state, only rotation of a predetermined rotational element provided in planetary gear mechanisms in a first direction is restricted. In the second state, rotation of the predetermined rotational element in both the first and second direction is restricted. The determination unit determines to switch the mechanism to the first state at least on condition that a driving force is larger than a predetermined driving force.

Claim (Index 1):
A control apparatus of an automatic transmission,\n wherein the automatic transmission includes: an input shaft to which a driving force is input from a driving source through a torque converter; an output member; a plurality of planetary gear mechanisms configured to transmit the driving force input to the input shaft to the output member; and a plurality of engaging mechanisms capable of establishing a plurality of gears by switching a transmission path of the driving force in the plurality of planetary gear mechanisms, one of the plurality of engaging mechanisms is a mechanical engaging mechanism functioning as a brake, the mechanical engaging mechanism can be switched to a first state in which only rotation of a predetermined rotational element of a plurality of rotational elements provided in the plurality of planetary gear mechanisms in a first direction is restricted and a second state in which the rotation of the predetermined rotational element in both the first direction and a second direction reverse to the first direction is restricted, the plurality of gears include: a lowest forward speed gear in which the mechanical engaging mechanism can be established in both the first state and the second state; a forward gear in which a gear ratio is higher than in the lowest forward speed gear, and the mechanical engaging mechanism cannot be established in the second state; and a reverse gear in which the mechanical engaging mechanism is established in the second state, the control apparatus comprises: a determination unit configured to, when a selected gear is the lowest forward speed gear, and the mechanical engaging mechanism is in the second state, determine whether to switch the mechanical engaging mechanism to the first state; and a switching processing unit configured to switch the mechanical engaging mechanism to the first state based on a determination result of the determination unit, and the determination unit determines to switch the mechanical engaging mechanism to the first state at least on condition that the driving force is larger than a predetermined driving force.
