Publication number: 20170284483Abstract: In a clutch engagement control system for engagement and disengagement of transmission of a rotational force between a mainshaft and a countershaft, when clutch engagement control is executed based on the determination that rotational speeds of both the shafts agree with each other, even if unexpected variations in countershaft rotational speed result from torsion occurring downstream of the countershaft in a drive system and/or the like, smooth engagement control is implemented. A control value of countershaft rotational speed at each time is updated and managed. If a threshold value is exceeded by a difference between a countershaft rotational speed actual measured value and the preceding control value, the threshold value is added to the preceding value to obtain the control value. If the threshold value does not exceed the difference, the actual measured value at this time is set as a control value without any change.Type: ApplicationFiled: March 2, 2017Publication date: October 5, 2017Inventors: Junya Ono, Tatsuya Ryuzaki

Patent number: 9481372Abstract: After a speed change operation mechanism has changed gear position during a shift in a vehicle, a controller operates an actuator to put a clutch into a partial clutch engagement state, thereby reducing difference rotation Nd of the clutch, and temporarily lowers an output of an engine below a normal-time output. After the difference rotation of the clutch is reduced, the controller returns the engine output to the normal-time output, and operates the actuator to bring the clutch into a full capacity state. The standard difference rotational speed Nds is variable according to the throttle position Th detected by the engine load detection means.Type: GrantFiled: March 21, 2016Date of Patent: November 1, 2016Assignee: HONDA MOTOR CO., LTD.Inventors: Junya Ono, Yoshiaki Nedachi, Tatsuya Ryuzaki
