Document Type and Number:
Japanese Patent JP2008138809
Kind Code:
A
Abstract:
To realize a drive force requested by a driver even during the transition period of engagement of a lock-up clutch.
An ECU comprises a step (S1000) of detecting an accelerator opening TA, a step (S1100) of detecting a vehicle speed V, and a step (S1700) of calculating a speed ratio E when the lock-up of the clutch is changed from off to on (YES in S1300). Until the speed ratio E becomes 1 (YES in S1800), a step (S2100) of calculating a requested turbine torque reduction amount TtDWN is calculated (S1900), calculating a driver requested gain G_d (S2000), and calculating a requested turbine torque correction amount TtCOMP from TtDWN and G_d.
