摘要: In a hydraulic control device, when a solenoid pressure from a linear solenoid valve is not supplied to a brake, which is normally not engaged at the same time as a brake, not to engage the brake, a switching valve is supplied with a line pressure as a signal pressure for establishing a blocked/discharge state in which supply of the solenoid pressure to the brake is blocked and a hydraulic pressure can be discharged from the brake. When the solenoid pressure is supplied to the brake to engage the brake, the switching valve is supplied with a modulator pressure, which is lower than the line pressure, as a signal pressure for establishing a communicated state in which the solenoid pressure can be supplied to the brake.

摘要: An oil pressure control apparatus for an automatic transmission configured with an oil pressure servo that engages and disengages a friction engagement element. The friction element is engaged by first and second hydraulic oil chambers that individually provide low torque, and can provide a higher torque when working in combination. A failure solenoid valve outputs a signal when a failure occurs to stop oil pressure to an oil pressure servo. Valves are configured to determine whether oil pressure is supplied to or discharged from the first and second hydraulic oil chambers. A switching valve is switched on the basis of the failure signal, and an oil pressure can be individually supplied to and discharged from the first and second hydraulic oil chambers based on the status of the switching solenoid valve and the signal from the failure solenoid valve.
