Document Type and Number:
WIPO Patent Application WO/2017/138194
Kind Code:
A1
Abstract:
The purpose of the present invention is to shorten the time required until completion of lock-up engagement in travel scenarios in which simultaneous execution of lock-up engagement and upshifting is required. A vehicle has an engine for the driving source and a continuously variable transmission (6) provided with a torque converter (4) with a lock-up clutch (3) is installed therein. In said engined vehicle, when simultaneous execution of lock-up engagement of the lock-up clutch (3) and upshifting of the continuously variable transmission (6) is called for as a result of the driver stepping on the accelerator pedal, LU engagement control of the lock-up clutch (3) is initiated in response to the call for LU engagement. Meanwhile, upshifting control by the continuously variable transmission (6) stands by for initiation of control in response to a call for upshifting, and cancels the standby state and initiates upshifting control when the lock-up engagement completion range is reached in the LU engagement control of the lock-up clutch (3) (delay control).
