Title:
デュアルクラッチ式変速機
Document Type and Number:
Japanese Patent JP5869283
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a dual clutch type transmission capable of holding an excellent jointing motion performance without lowering the accuracy of a touch point even in a clutch in the side where touch point learning opportunities are few.SOLUTION: The dual clutch type transmission has first and second friction clutches, a first transmission mechanism disconnectably and rotatably coupled to a drive source by a first friction clutch, a second transmission mechanism disconnectably and rotatably coupled to the drive source by the second friction clutch, and a control section, the control section has a means learning touch stroke amounts (St11 to St18, St21, St24) when controlling a joint motion of the clutch, a means obtaining a first accumulated work volume J1 and a second accumulated work volume J2 by accumulating work volumes which the two clutches do in the joint motions respectively, and a touch point estimating means estimating the touch stroke amount St28 of one of the clutches based on the first and second accumulated work volumes J1, J2 when the learning is not done in the one of the clutches for the predetermined period (time t4 to t8).
