Patent ID: 8066618

Claim:
A hydraulic control device for a starting device, the hydraulic control device comprising: a first oil path that inputs an internal pressure to the starting device that includes a clutch; a second oil path that discharges the internal pressure; a third oil path that inputs an engagement pressure of the clutch; an engagement pressure generation unit that outputs the engagement pressure of the clutch to the third oil path; a signal pressure generation unit that outputs a signal pressure when the engagement pressure is not inputted, and outputs no signal pressure when the engagement pressure is inputted; and an internal pressure switching unit that switches between: a non-reduced pressure state where locking occurs due to the signal pressure inputted and a source pressure is outputted unchanged as internal pressure to the first oil path, and a reduced pressure state where the signal pressure is not inputted and a hydraulic pressure is regulated to a constant pressure from the source pressure, based on a feedback pressure of the internal pressure and an urging force of a first urging unit, and outputted as the internal pressure to the first oil path.
