    摘要: A hydraulic control apparatus for an automatic transmission is provided with a solenoid valve that outputs a signal pressure during a failure and does not output a signal pressure during normal operation and a first clutch apply relay valve that switches between a normal position (the right half position) and a fail position (the left half position) based on this signal pressure are provided. During a failure, fail-safe control is carried out by the first clutch apply relay valve switching to the fail position. The first clutch apply relay valve inputs the engagement pressure of the hydraulic servo from the linear solenoid valve when in the normal position, and is locked in the normal position. Thereby, while the first clutch is engaged, the second brake apply control valve can be switched by the signal pressure of the solenoid valve.

    摘要: A hydraulic control apparatus, provided with a manual shift valve that outputs a forward range pressure and a reverse range pressure, and a linear solenoid valve that outputs an engagement pressure to the hydraulic servo that engages during reverse travel when energized, includes a fourth clutch relay valve that is interposed between the linear solenoid valve and the hydraulic servo. The fourth clutch relay valve communicates an engagement pressure of the linear solenoid valve to the hydraulic servo by locking in the normal position when a signal pressure of the solenoid valve is input, and communicates a reverse range pressure to the hydraulic servo by being switched to a fail position by the reverse range pressure during a failure in which the fourth clutch relay valve is de-energized. Thereby, it is possible to establish a reverse speed during a failure in which the solenoid valve is de-energized.

    摘要: An automatic transmission is capable of shifting between multiple speeds by engaging and disengaging multiple frictional engagement devices including at least one clutch and one brake, and is capable of switching between a driving range and a non-driving range with operation of a shift lever, wherein a first brake is engaged to fix an intermediate rotary member to a transmission case in a non-driving range such as neutral range. Thus, rotation of a clutch from drag torque can be stopped and shock due to engagement of a brake can be prevented by engagement of the first brake in the non-driving range.

    摘要: A fluid pressure control device controls input and output of a fluid pressure to and from a fluid chamber in a device that transfers power from a motor via working fluid in the chamber, the chamber being partitioned into engagement and disengagement oil chambers by a lock-up clutch. A signal pressure output valve performs pressure regulation to output a signal pressure. The control device includes a control valve connected to an output source flow passage leading to an output source of the fluid pressure, and a control unit controlling the signal pressure output valve so the control valve establishes a first state when the lock-up clutch is turned off, establishes a third state when the lock-up clutch is turned on, and establishes a second state so the working fluid can be confined in the disengagement oil chamber when the lock-up clutch is switched on.
