Title:
CONTROL DEVICE FOR DUAL-CLUTCH TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2017/141937
Kind Code:
A1
Abstract:
The invention is provided with: a clutch control unit 83 that, when a downshift instruction is detected by a transmission control device 80 and in the event that an accelerator is off, the gear position on a gear shift destination clutch side is lower than on a gear shift source clutch side, and the clutch that engages with an engine 10 can be switched from the gear shift source clutch to the gear shift destination clutch, controls the engagement force of both clutches such that the engine rotational speed is equal to or less than the rotational speed of a gear shift source input shaft, and performs control such that the gear shift source clutch is changed to a disengaged state and the gear shift destination clutch is changed to a half-clutch state; and a synchronization control unit 84 that, when the rotational speed of a gear shift source input shaft is equal to or less than a maximum allowable rotational speed, increases the engine rotational speed so as to match the rotational speed of a gear shift destination input shaft. After the engine rotational speed and the rotational speed of the gear shift destination input shaft are made to match, the clutch control unit 83 configures the gear shift destination clutch to be controlled in a connected state.
