摘要: A hydraulic control device for an automatic transmission where the spool is locked at the first position and the switching pressure can regulate the belt holding force of the primary pulley or the secondary pulley without switching a position of the spool when the engagement pressure is supplied to the second working oil chamber, and the spool is not locked at the first position and the switching pressure can switch the spool to the second position against the urging member when the engagement pressure is not supplied to the second working oil chamber.

摘要: A hydraulic control device has: a modulator valve using oil pressure from a hydraulic source for adjusting a modulator pressure; driving and driven-side hydraulic actuator control valves controlling hydraulic oil from the source to driving and driven-side hydraulic actuators; a driving-side control oil pressure adjusting electromagnetic valve using the modulator pressure for outputting a control oil pressure controlling the driving-side control valve; and a driven-side control oil pressure adjusting electromagnetic valve for outputting a control oil pressure controlling the driven-side control valve, the hydraulic control device including a failsafe valve switched from a normal to a failure position based on a failure disabling electric control for the driving-side and driven-side electromagnetic valves, the modulator valve making the modulator pressure lower than a value at the normal position based on an output switching pressure generated due to switching the failsafe valve from the normal to the failure position.

摘要: When engagement of a lockup clutch is initiated, coupling of the lockup clutch is initiated in a state where a working fluid amount is sufficiently ensured by setting a condition that an engine rotation speed is higher than or equal to a limit engine rotation speed. Thus, it is possible to prevent rapid engagement of the lockup clutch. Here, the limit engine rotation speed is appropriately determined on the basis of a line pressure, and it is possible to reduce a delay of coupling of the lockup clutch by ensuring the working fluid amount while preventing rapid engagement of the lockup clutch.

摘要: An automatic transmission where the first engagement element is positioned between the continuously variable speed change mechanism and a portion of the second power transmission path on the wheel side, at which the second power transmission path is coupled to the first power transmission path, and is allowed to be switched to the disengaged state for inertial traveling.
