Patent number: 10539229Abstract: An engagement operation of a dog clutch is carried out while an engagement operation of a second clutch is being carried out, that is, during a situation that an uplock is hard to occur because of a phase shift generated between meshing counterpart members of the dog clutch. Thus, the dog clutch is easily engaged, and it is possible to facilitate preparation for transmission of power through a first power transmission path. If the dog clutch is not engaged, the second clutch is engaged and a second power transmission path is established, so it is possible to start moving a vehicle by transmitting power through the second power transmission path. Thus, when the dog clutch is in a non-engaged state at the time of an N-to-D shift during a stop of the vehicle, it is possible to ensure the startability of the vehicle.Type: GrantFiled: November 17, 2015Date of Patent: January 21, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Daisuke Inoue, Akihide Ito, Kazuya Sakamoto, Hiroki Kondo, Mitsuhiro Fukao, Kenji Matsuo
