摘要：To optimize the application hydraulic pressure of the friction applicationelements in the transmission mechanism M, and to reduce the unnecessary load on eachmember. The transmission mechanism M of an automatic transmission T is provided witha plurality of friction application elements B-1, B-2, B-3, C-1, C-2, B-R which are appliedsimultaneously in order to achieve the designated gear stage, and hydraulic servos whichoperate these independently. The control apparatus has an information detecting means60, an input torque calculating means 6 which calculates the input torque of thetransmission mechanism M on the basis of this information, an application hydraulicpressure calculating means 6 which calculates the necessary application hydraulicpressure required to maintain the application of each individual friction applicationelement on the basis of the input torque, and a supply means 5 which supplies thenecessary application hydraulic pressure to the hydraulic servos of the friction applicationelements. The supply means 5 makes the hydraulic pressure supplied to each hydraulicservo the necessary application hydraulic pressure calculated for each friction application

element independently when achieving the designated gear stage.
