Patent number: 10612651Abstract: 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 (?·Ne2). 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.Type: GrantFiled: August 31, 2016Date of Patent: April 7, 2020Assignees: JATCO LTD, NISSAN MOTOR CO., LTD.Inventors: Toshimitsu Araki, Hideshi Wakayama, Kouji Saitou, Seiji Kasahara, Tetsuya Izumi

Patent number: 10480648Abstract: 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).Type: GrantFiled: August 31, 2016Date of Patent: November 19, 2019Assignees: JATCO LTD, NISSAN MOTOR CO., LTD.Inventors: Toshimitsu Araki, Seiji Kasahara, Hideshi Wakayama, Hiroyasu Tanaka

Patent number: 10371256Abstract: In a vehicle on which a torque converter having a lock-up clutch is mounted between an engine and a transmission, a meet point learning controller is provided to perform learning control for obtaining a learning value based on information on a meet point at which the lock-up clutch starts torque transmission. The meet point learning controller estimates a LU transmission torque based on a difference between an engine torque signal value and a torque converter transmission torque when the lock-up clutch 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 at a time when the LU transmission torque estimated value is determined to have entered an upward trend.Type: GrantFiled: August 12, 2016Date of Patent: August 6, 2019Assignees: JATCO LTD, NISSAN MOTOR CO., LTD.Inventors: Toshimitsu Araki, Seiji Kasahara, Hideshi Wakayama, Kouji Saitou, Hiroyasu Tanaka
