Hydraulic control apparatus of transmission |
摘要 |
A hydraulic control apparatus for a transmission includes a line pressure regulating device that enables control in which an oil pressure from an oil pump is regulated so as to attain a line pressure, and that enables control in which the line pressure is switched stepwise between a low pressure state in a lower pressure range and a high pressure state in a higher pressure range; a plurality of hydraulic servos that engage and disengage friction engaging elements using engagement pressures that are based on the line pressure; and a high pressure state detecting device that detects that the line pressure regulating device is outputting the line pressure in the high pressure state.
