Abstract:
1. A method for engagement of an impeller clutch, comprising: performing 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, wherein the impeller clutch enables a driving force of an engine to be transmitted and disconnected to and from a pump impeller of the torque converter, wherein transmission and disconnection of the driving force between the engine and the pump impeller is controlled by the clutch engagement pressure that is applied to the impeller clutch through an independent oil passage, and wherein the process is performed when a brake pedal of a vehicle on which the impeller clutch is mounted is released, when an accelerator pedal of the vehicle is pressed, or when a shift lever is selected to a drive mode.
