Abstract
A method for engagement of an impeller clutch includes a process for decreasing a back pressure relative to a clutch engagement pressure by decreasing an internal pressure of a torque converter in a case where the impeller clutch is brought into an engaged state, the impeller clutch enabling a driving force of an engine to be transmitted and disconnected to and from a pump impeller of the torque converter, transmission and disconnection of the driving force between the engine and the pump impeller being controlled by the clutch engagement pressure that is applied to the impeller clutch through an independent oil passage.
