Patent number: 11041535Abstract: A control apparatus for a synchronous meshing mechanism that is equipped with a gear, a sleeve, a synchronizer ring, and a hydraulic actuator is provided. When it is determined that the sleeve and the gear have been rotationally synchronized with each other in an engagement transition period of the synchronous meshing mechanism, an electronic control unit with which the control apparatus is equipped sets a command pressure for the hydraulic actuator to an intermediate pressure that is lower than a meshing completion pressure. Besides, when meshing has not been completed even after the lapse of a predetermined time from a timing when the command pressure for the hydraulic actuator is set to the intermediate pressure, the electronic control unit sets the command pressure for the hydraulic actuator to the meshing completion pressure.Type: GrantFiled: May 22, 2020Date of Patent: June 22, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Ken Jozaki, Takashi Seo, Toshio Suzuki, Hiroki Takeda, Yoshisuke Kametani, Shun Minaki
