Patent number: 10364884Abstract: A gear shift mechanism controlled by a gear shift control device includes a plurality of engagement mechanisms and engages three engagement mechanisms to establish any one of a plurality of shift stages. The gear shift control device is adapted to change speed to a desired shift stage set by a manual operation. If a gear shift to the desired shift stage involves the skipping of one or more shift stages and the switching of two or more engagement mechanisms among the plurality of engagement mechanisms that are currently engaged, then the gear shift control device performs the gear shift to the desired shift stage such that the engagement mechanisms to be switched via a shift stage or stages to be skipped are switched one by one.Type: GrantFiled: March 2, 2017Date of Patent: July 30, 2019Assignee: HONDA MOTOR CO., LTD.Inventors: Kazuma Sasahara, Shintaro Kameda, Christopher Hopp

Patent number: 9562588Abstract: A control apparatus for an automatic transmission includes a vehicle speed detector and a controller. The vehicle speed detector is configured to detect a vehicle speed. The controller is configured to set one of a plurality of gear change stages according to a running condition of a vehicle and configured to select one of a plurality of engagement combination states of a plurality of engagement mechanisms to achieve, according to the vehicle speed detected by the vehicle speed detector, at least one gear change stage out of the plurality of gear change stages in a case in which the controller sets the at least one gear change stage. The at least one gear change stage has the plurality of engagement combination states to achieve the at least one gear change stage.Type: GrantFiled: March 31, 2014Date of Patent: February 7, 2017Assignee: HONDA MOTOR CO., LTD.Inventors: Shintaro Kameda, Eri Kubota

Patent number: 8989973Abstract: A control apparatus for an automatic transmission includes a running condition detector and a controller. a plurality of gear change stages include at least one specific gear change stage that has a specific transmission gear ratio, that involves at least one necessary engagement mechanism which needs to be engaged in order to obtain the specific transmission gear ratio, and that involves at least one no-change engagement mechanism which causes no change in the specific transmission gear ratio. Both of the at least one necessary engagement mechanism and the at least one no-change engagement mechanism are engaged during a time period from a timing to begin an operation to change a gear change stage to the specific gear change stage until a timing to complete the operation. The at least one no-change engagement mechanism is released after the timing to complete the operation.Type: GrantFiled: April 1, 2014Date of Patent: March 24, 2015Assignee: Honda Motor Co., Ltd.Inventors: Shintaro Kameda, Kohsaku Matsuo, Eri Kubota
