POWER TRANSMISSION CONTROL DEVICE FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To acquire a touch point of a clutch without affecting the acceleration/deceleration state of a vehicle during traveling of the vehicle in a power transmission control device for the vehicle using a double clutch transmission.SOLUTION: During vehicle traveling, an unselected system (system where the clutch is disengaged) within the transmission is made in an open state (t1). Then, a clutch stroke St2 of the clutch in the unselected system is gradually increased from zero (after t2). Thus, rotational frequency Ni2 of an input shaft in the unselected system is increased. After a time point (t3) where the increased Ni2 reaches engine speed Ne, the St2 is gradually decreased. This decreases the Ni2. The St2 at a time point (t4) where a change rate of the Ni2 becomes zero is acquired as the touch point of the clutch in the unselected system.
