Abstract
A control apparatus for a hydraulically-operated vehicular transmission, to buffer in-gear shocks in any driving condition of a vehicle, includes a pressure regulating solenoid valve for controlling an oil pressure in a hydraulic engaging element which establishes a predetermined speed transmission train of the hydraulically-operated vehicular transmission, an accumulator connected to an oil passage which is communicated with the hydraulic engaging element, a discriminator for discriminating whether the pressure accumulation in the accumulator-has been completed or not, and a controller for maintaining an outlet pressure of the pressure regulating solenoid valve at a predetermined pressure until the pressure accumulation in the accumulator has been completed and for increasing the output pressure of the pressure regulating solenoid valve, after the pressure accumulation in the accumulator has been completed, depending on a driving condition of the vehicle.
