Document Type and Number:
WIPO Patent Application WO/2016/056461
Kind Code:
A1
Abstract:
In the present invention, in relation to a control device for a dual clutch-type transmission, the learning accuracy of transmission torque is improved. Provided are the following: a clutch device 20 that has a first clutch 21 and a second clutch 22; a first input shaft 31; a second input shaft 32; a sub-shaft 34; an output shaft 33; a sub-transmission unit 40 that includes a first input gear pair 41 and a second input gear pair 42; a main transmission unit 50 that includes an output gear pair 51; and learning units 61, 62 that put the main transmission unit 50 into a neutral state and the first and second clutches 21, 22 into a disconnected state, that maintain an engine 10 at a prescribed rotation speed and put one clutch from between the first and second clutches 21, 22 into a half-clutch state and thereafter gradually put the other clutch into a half-clutch state to generate torque variation in the engine 10, and that learn the torque variation amount associated with the torque variation as the transmission torque of the other clutch.
