Document Type and Number:
Japanese Patent JP3122987
Kind Code:
B2
Abstract:
Disclosed is a hydraulic control system including a hydraulic fluid source; line pressure control means for regulating hydraulic pressure supplied from the fluid source to line pressure; reducing pressure controller for reducing hydraulic pressure from the line pressure control means; range controller for selectively supplying hydraulic pressure from the line pressure controller; shift controller for supplying hydraulic pressure; hydraulic pressure controller for converting hydraulic pressure to operational pressure; and hydraulic pressure distributer for determining a hydraulic flow path according to the hydraulic pressure from the shift controller; wherein the hydraulic pressure distributer includes an end clutch valve supplying operational pressure to an end clutch; a low-reverse brake valve supplying operational pressure to a low-reverse brake; a first rear clutch valve supplying operational pressure to a rear clutch; a second rear clutch valve supplying hydraulic pressure to the first rear clutch valve; a 1-2 shift valve supplying hydraulic pressure to friction elements operating when 1-2 shifting; and a 2-3/4-3 shift valve supplying hydraulic pressure to friction elements operating when 2-3 and 4-3 shifting.
