Title:
DEVICE FOR CONTROLLING DUAL-CLUTCH AUTOMATIC TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2013/035784
Kind Code:
A1
Abstract:
Provided is a device for controlling a dual-clutch automatic transmission able to smoothly and without shocks reverse the engagement/disengagement state of both clutches even while increasing the depression of an accelerator during shifting, and thus can achieve a favorable shifting feeling. During shifting that reverses the engagement/disengagement state of the clutches (C1, C2), both clutch torques are controlled on the basis of a request torque applied in engine control, and meanwhile when the accelerator is depressed more during shifting, the request torque is subjected to moderating processing by a filter circuit (29) in a manner so as to increase similarly to the rise of actual engine torque that, with a lag, tracks the stepped increase of the request torque, and clutch torque is controlled on the basis of the post-processing request torque.
