HYDRAULIC CONTROL DEVICE FOR VEHICLE DRIVE DEVICE

摘要

The present invention is provided with a range switching unit (53) that, in a normal mode and when a shift position is in a forward travel range, switches a spool to a first position and self-holds, that, in an all-off fail mode and when the shift position is in the forward travel range, maintains self-holding of the spool in the first position and supplies hydraulic pressure to engaging elements (C1, C2) that form a first gear stage, that, in normal mode and when the shift position is in a reverse travel range, switches the spool to a second position, and that, in all-off fail mode and when the shift position is in the reverse travel range, supplies hydraulic pressure to engaging elements (C1, B2) that form a second gear stage.
