Document Type and Number:
WIPO Patent Application WO/2012/073834
Kind Code:
A1
Abstract:
During a lock-up clutch slip control, when an amount of change dTHR in throttle opening angle exceeds an increase-side threshold value αin due to an increase in a throttle opening angle THR, a predicted engine torque Teest indicating an estimated value of output torque from an engine (12) according to the throttle opening angle THR is derived until a cancellation condition is met, and a hydraulic command value Pslu* for a hydraulic unit is set to correspond to the predicted engine torque Teest such that the slip number of rotations Nslip can reach a target slip number of rotations Nslip* (steps S2550-S2580, S2530, and S2540)｡
