Title:
DEVICE FOR CONTROLLING DUAL-CLUTCH AUTOMATIC TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2013/035785
Kind Code:
A1
Abstract:
Provided is a device for controlling a dual-clutch automatic transmission that constantly can smoothly and without shocks cause the reversing of the engagement/disengagement state of both clutches regardless of the size of the input torque from an engine during shifting, and thus can achieve a favorable shifting feeling. During shifting that reverses the engagement/disengagement state of the clutches (C1, C2), the rate of change of transmitted torque of both clutches (C1, C2) is set in the direction of increasing the larger a clutch total torque is, which totals the input torque to both clutches (C1, C2) from the engine (1), and on the basis of the rate of change, causes the reversing of the engagement/disengagement state by executing clutch control. When the input torque is low, by means of slowly controlling both clutches (C1, C2) on the basis of a low rate of change of the transmitted torque, sudden engagement by the clutches (C1, C2) on the connection side stemming from delayed control of the clutch system is prevented.
