...Bingzhao Gao; Hong Chen; Lu Tian; Kazushi Sanada For a new kind of automatic transmissions adopting clutch-to-clutch shift control technology, a clutch pressure observer is proposed to improve the estimation accuracy during the shift torque phase. The observer is designed in the concept of input...

...Xingyong Song; Mohd Azrin Mohd Zulkefli; Zongxuan Sun; Hsu-Chiang Miao Clutch to clutch shift control technology, which is the key enabler for a compact and low cost transmission design, is important for both automatic and hybrid transmissions. To ensure a smooth clutch to clutch shift, precise...

...Xingyong Song; Mohd Azrin Mohd Zulkefli; Zongxuan Sun; Hsu-Chiang Miao Clutch shift control is critical for the performance and fuel economy of automotive transmissions, including both automatic and hybrid transmissions. Among all the factors that influence clutch shift control, clutch fill...

...R. Hibino; M. Osawa; K. Kono; K. Yoshizawa A torque converter lock-up clutch slip control system, which is designed to improve fuel economy, must be able to precisely regulate slip speed. Also the system must have a high level of robustness for coping with changes in the operating conditions...

... advantage over regular modular robots in terms of the mass of each module. The drive is mounted at the robot base and all joints tap power from the single drive using clutches. By controlling the engagement time of the clutches, the position and velocity of the joints are regulated. In this work, a general...

...Joško Deur; Jahan Asgari; Davor Hrovat; Petar Kovač A control-oriented model of a typical four-speed automatic transmission is developed by using the bond graph modeling method. The planetary gear set model utilizes the Karnopp friction model for hydraulic and one-way clutches, in order to provide...

...Joško Deur; Jahan Asgari; Davor Hrovat A typical control-oriented automatic transmission model does not include some mostly nonlinear effects such as transmission component friction and backlash, Stribeck clutch friction, clutch drag, and engine block dynamics. It is shown in this paper...
