Patent number: 10190678Abstract: A twin-clutch transmission that can always effectively reduce gear shift shock and a collision sound even under the existence of variation attributed to component tolerance and change over the ages attributed to wear. A twin-clutch transmission calculates a rotational speed difference (|Na?Nb|) between an odd-stage main shaft rotational speed (Na) and an even-stage main shaft rotational speed (Nb) and learns synchronization start gear shift drive displacement (?s) detected by a gear shift drive displacement detecting unit at the timing at which the rotational speed difference (|Na?Nb|) reaches a predetermined synchronization start determination rotational speed difference (Ds) from gear shift start. The twin-clutch transmission controls an actuator on the basis of the learned synchronization start gear shift drive displacement (?s).Type: GrantFiled: March 16, 2016Date of Patent: January 29, 2019Assignee: HONDA MOTOR CO., LTD.Inventors: Kazuhiko Nakamura, Hiroyuki Kojima, Yoshihisa Kanno, Hiroshi Takamoto, Yoshiaki Tsukada, Takashi Ozeki
