Title: Controlling method of clutch
Inventor: INOUE EIJI
IPC: F16D48/02
Filed: 2001-11-30
Abstract: <P>PROBLEM TO BE SOLVED: To further shorten clutch releasing time.  <P>SOLUTION: There is provided a controlling method for releasing and disengaging a clutch by changing operating fluid pressure for driving a wet-type friction clutch by releasing and disengaging in proportion to duty-pulses supplied from an electronic control unit. When releasing the clutch from a disengaged state, a designated starting duty Dst is outputted for a designated time Δtst so as to release the clutch to a position being beyond a torque point. Then, slow releasing duty Dk is outputted every designated time Δt. Operating speed of the clutch becomes faster because a value of a starting duty turns to a releasing side (0%) more than before, and the output time Δtst of the starting duty is determined by tests of the actual clutch so that it is optimal in proportion to values of the starting duty Dst. Thus, an instant-releasing mode as in the past is now realized in a shorter time, and clutch releasing time is further shortened.  <P>COPYRIGHT: (C)2003,JPO
