HYDRAULIC PRESSURE SUPPLY DEVICE OF AUTOMATIC TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To efficiently supply hydraulic pressure stored in a frictional engaging device for starting.

SOLUTION: The hydraulic pressure is supplied from a hydraulic control device 7 to the frictional engaging device 29. While, when starting an engine from an idle stop, a hydraulic fluid from a pressure accumulating accumulator 46 is supplied to a frictional engaging device 29a for starting. The hydraulic fluid from the pressure accumulating accumulator 46 is supplied to the frictional engaging device 29a for starting by a system separate from the hydraulic fluid from the hydraulic control device 7.
