Abstract
A control apparatus for a vehicular transmission including at least one dog clutch each having a first dog member mounted on a first shaft such that the first dog member is rotated together with the first shaft, and at least one second dog member each mounted to be axially adjacent to the first dog member and rotatable relative to the first shaft, first gears each mounted to be rotatable relative to the first shaft and provided with the second dog member, second gear which are mounted such that the second gears are rotated together with a second shaft parallel to the first shaft, and which mesh with the respective first gears, and a shifting mechanism for selectively placing each dog clutch in an engaged or released state. The control apparatus includes: a first calculating portion for detecting to a rotary angular position of the first shaft, and calculating a rotary angular position of the first dog member on the basis of the detected rotary angular position of the first shaft; a second calculating portion for detecting a rotary angular position of the second shaft, and calculating a rotary angular position of each second dog member on the basis of the detected rotary angular position of the second shaft; and an engagement control portion for controlling the shifting mechanism on the basis of the rotary angular positions of the first and second dog members, for engagement of the first and second dog members with each other.
