Inventor: KATO YOSHIAKI
IPC: F16H59/26
Filed: 2010-04-26
Abstract: PROBLEM TO BE SOLVED: To enhance responsiveness of restart of an automatic transmission vehicle performing idling stop using an accumulator.SOLUTION: The accumulator is connected to a hydraulic circuit of an automatic transmission via a solenoid shut-off valve. At restart t1 of an engine after idling stop, the solenoid shut-off valve is made to become a communication state and hydraulic pressure is discharged from the accumulator to a line pressure oil passage, so as to compensate shortage of hydraulic pressure of an oil pump. A stroke sensor detecting stroke amount of a piston is attached to the accumulator, and when the stroke amount is reversed from the discharge direction of the hydraulic pressure to a pressure accumulation direction, the solenoid shut-off valve is made to become a shut-off state at time t3. Thus, in the middle of increase in the hydraulic pressure of the oil pump, the hydraulic pressure from the oil pump is exclusively used for filling within the hydraulic pressure circuit and increase in the hydraulic pressure without filling in the accumulator. As a result, narrowing of a stroke of the clutch can be promptly progressed, so as to obtain high degrees of responsiveness.
