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. 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： The present invention relates to a control device and a control method for a vehicle in which a lockup clutch (2c) is disengaged when a rotation speed of an engine (1) falls below a disengagement rotation speed. The device / method changes a speed ratio of a variator (20) on the basis of a shifting map in which a primary pulley rotation speed (Npri) on a coast line is set higher than a primary pulley rotation speed (Npri) on a drive line and sets a target input rotation speed (Nint) of the variator (20) to a predetermined target input rotation speed (Nintp) higher than the primary pulley rotation speed (Npri) on the drive line when an operation of an accelerator pedal (51) is performed such that an accelerator pedal opening (APO) falls to a first predetermined opening or less. As a result, the present invention can suppress drop of fuel efficiency of the engine (1) caused by disengagement of the lockup clutch (2c) which is a friction engagement element.

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).
