Abstract
The valve closing control is performed to close the waist gate valve of the turbocharger when the hydraulic fluid temperature is less than the temperature threshold. By closing the waist gate valve, the output torque is increased by increasing the amount of air taken into the engine that is idling operation, to suppress the engine stall that may occur when switching from the non-driving range to the driving range.
