摘要:
A hydraulic control device that includes a source pressure generating valve that generates a source pressure; a solenoid valve that can supply the engagement pressure based on the source pressure; and a supply pressure switching valve that can be switched between a first state where the supply pressure switching valve can supply the engagement pressure to the second engagement element and a second state where the supply pressure switching valve can supply the source pressure to the second engagement element, the supply pressure switching valve being in the first state when the solenoid valve is operating normally, and being switched to the second state in case of abnormality in the solenoid valve.
