摘要： In a transmission, a controller sets a target line pressure to an offset target value, which is a value obtained by adding a positive offset amount to one of a target PRI pressure and a target SEC pressure, in a speed ratio range in which the offset target value is higher than the other at least during an inertia phase in a sub-transmission mechanism when a coordinated shift is carried out. At that time, the one of the target PRI pressure and the target SEC pressure is the target SEC pressure when a variator is downshifted by the coordinated shift while being the target PRI pressure when the variator is upshifted by the coordinated shift.

摘要： In a vehicle equipped with a torque converter 4 having a lock-up clutch (3), learning control for obtaining a learning value (L_n) on the basis of meet-point information, with which the lock-up clutch (3) initiates torque transmission, is carried out. When the lock-up clutch (3) experiences a transition to an engaged state during travel, a meet-point learning control unit (12c) calculates an LU transmission torque estimate on the basis of the difference between the engine torque (engine torque signal value Te) and the torque converter transmission torque (τ·N 2 ). Excess clutch capacity is detected when the LU transmission torque estimate is greater than an excess capacity determination transmission torque threshold within a prescribed amount of time after an initial pressure (P_n) based on the learning value (L_n) is instructed. When excess clutch capacity is detected, a learning value correction that reduces the learning value (L_n) is carried out.

摘要： In a vehicle on which a torque converter (4) having a lock-up clutch (3) is mounted between an engine (1) and a transmission (6), a meet point learning controller (12c) is provided to perform learning control for obtaining a learning value (L) based on information on a meet point at which the lock-up clutch (3) starts torque transmission. The meet point learning controller (12c) estimates a LU transmission torque based on a difference between an engine torque signal value (Te) and a torque converter transmission torque (τ×Ne 2 ) when the lock-up clutch (3) moves from a non-engaged state to an engaged state during traveling of the vehicle, and uses, as the meet point information, a meet point detection pressure (LUPRSEDGE) at a time when the LU transmission torque estimated value is determined to have entered an upward trend.

摘要： In a vehicle equipped with a torque converter (4) having a lock-up clutch (3), learning control for obtaining a learning value (L_n) on the basis of meet-point information, with which the lock-up clutch (3) initiates torque transmission, is carried out. After acquiring the current learning detection value (M_n), a meet-point learning control unit (12c) calculates the current detection error (E_n) on the basis of the difference between the current learning detection value (M_n) and the previous learning value (L_(n-1)) that is stored. When the current and previous detection errors (E_n) and (E_n-1) have the same plus/minus sign, the current learning value correction amount is set to a larger value if the absolute value |(E_n-1)| of the previous detection error (E_n-1) is large than if the absolute value |(E_n-1)| is small. The sum of the previous learning value (L_(n-1)) and the current learning value correction amount is set as the present learning value (L_n).
