CONTROL DEVICE AND CONTROL METHOD FOR CONTINUOUSLY VARIABLE TRANSMISSION

An ECU executes a program including the steps of: learning a differential pressure of a lock-up clutch (S100); determining whether or not learning has been completed (S140) when a vehicle is in a coasting state and a brake is applied (YES at S110 and YES at S130); lowering the lock-up differential p...

Zusammenfassung:	An ECU executes a program including the steps of: learning a differential pressure of a lock-up clutch (S100); determining whether or not learning has been completed (S140) when a vehicle is in a coasting state and a brake is applied (YES at S110 and YES at S130); lowering the lock-up differential pressure such that the lock-up clutch can be disengaged immediately and prohibiting or suppressing control for increasing transmission gain (S150, S160) when learning has been completed (YES at S140); and increasing a lower limit guard value for the lock-up differential pressure and performing control for increasing the transmission gain (S170, S180) when learning has not been completed (NO at S140).
