PROBLEM TO BE SOLVED: To control oil pressure to match input shaft torque even when response delay exists in real oil pressure to indicated oil pressure to a friction engagement element. SOLUTION: Based on intake air quantity Q (S1) and engine rotation speed Ne (S2), generated torque of an engine is estimated (S3). A phase advance process is applied to the estimated generated torque of the engine (S4), and based on the phase advance-processed generated torque and a torque ratio of a torque converter (S6), input shaft torque of a transmission is estimated. Indicated oil pressure to a friction engagement element is determined in accordance with the phase advance-processed input shaft torque, and a solenoid is controlled (S7-S9). |
