Abstract: A hydraulic control device configured with a source pressure generation section, a hydraulic servo for a clutch provided between an engine and a motor, a control solenoid valve that outputs a regulated source pressure to the hydraulic servo, and a switching section that switches a hydraulic passage, which extends between the source pressure generation section and the hydraulic servo to supply the engagement pressure, between a first and second state in which the hydraulic passage has a high conduit resistance compared to the first state at least until the clutch is engaged. The switching section switches the hydraulic passage into the second state during a failure in which the control solenoid valve is de-energized and the source pressure is directly supplied to the hydraulic servo as the engagement pressure, and switches the hydraulic passage into the first state during normal times when the failure does not occur.

Abstract: A hydraulic control device for an automatic transmission that includes a fail-safe function to establish a fail-safe traveling state where a predetermined shift speed is established, and a fail-safe stopping state where the primary pressure to all of the hydraulic servos is cut-off when a failure occurs. The hydraulic control device is able to switch between the fail-safe traveling state and the fail-safe stopping state even after a failure occurs, thereby enhancing a limp-mode function.

Abstract: A parking switching valve includes a spool that is movable to a first position and to a second position. The parking switching valve also has an oil chamber that generates a biasing force from a difference in the pressure receiving area between the land portions of the spool. The oil chamber has a second input port to which a line pressure is input while the spool is in the second position. Because the line pressure is input to the second input port, a biasing force is generated so that the spool is held in the second position against a spring. As a result, a parking device is held in a parking release state.

Abstract: A vehicle hydraulic control device for driving a parking rod to a parking disengagement position and a parking engagement position, and switching a shift range at least between a parking range and a non-parking range by switching an engagement state of a parking gear and a parking pole. The vehicle hydraulic control device includes a parking cylinder and a switch valve. The parking cylinder receives an oil pressure for driving the parking rod to the parking disengagement position. The switch valve is driven based on an electric actuator and switches an operation state between a parking disengagement state in which a source pressure from an oil pressure supply source is supplied to the parking cylinder as a disengagement pressure for disengaging the parking gear and the parking pole from each other, and a parking engagement state in which the disengagement pressure is not supplied to the parking cylinder.

Abstract: A hydraulic control device for a multi-speed automatic transmission includes friction engagement elements, several hydraulic servos that engage and release the friction engagement elements, solenoid valves for engagement control, and a sorting switch valve that allocates engagement pressure from at least one of the solenoid valves for engagement control to two of the hydraulic servos. The sorting switch is switched between a first position that supplies engagement pressure to one of the two hydraulic servos in at least a Reverse, non-drive range and a specific Forward gear range, and a second position that supplies engagement pressure to the two hydraulic servos in other than the Forward range. The hydraulic control device supplies the engagement pressure to the two hydraulic servos when an all-solenoids-off failure occurs and the sorting switch is in the second position, and cuts off a source pressure to all solenoid valves when an all-solenoids-off failure occurs while the sorting switch valve is in the first position.
