Patent ID: 6974009

Claim:
A control apparatus for a power train including a continuously variable transmission and a clutch that is arranged in series with the continuously variable transmission, comprising: an engaging pressure reducing unit that reduces an engaging pressure of the clutch that is in a fully engaged state until a slip of the clutch occurs; a re-engaging unit that increases the engaging pressure of the clutch after detection of the slip so as to re-engage the clutch; a pressure calculating unit that calculates the engaging pressure of the clutch by giving a predetermined excess pressure to the engaging pressure at which the clutch is re-engaged, such that an excess amount of a transmitted torque of the clutch over a transmitted torque with which a slip occurs in the clutch is set smaller than an excess amount of a transmitted torque of the continuously variable transmission over a transmitted torque with which a slip occurs in the transmission; and a learned value determining unit that determines a learned value as a correction value of the engaging pressure that is set in advance in accordance with an input torque applied to the clutch, based on the engaging pressure calculated by giving the predetermined excess pressure to the engaging pressure at which the clutch is re-engaged.
