ABSTRACT:
An engine torque detection method for a vehicular drive mechanism and a hydraulic control method for the transmission utilizing the torque detection method, the driving mechanism including a driving force transmission apparatus interposed between an internal combustion engine and wheels, having an input shaft connected to the engine an output shaft connected to the wheels, and capable of detecting a transmission torque transmitted from the input-shaft side to the output-shaft side; and a gear transmission system interposed between the driving force transmission apparatus and the wheels, and having a plurality of frictional engagement means for transmission control adapted to be engaged and disengaged in accordance with an operating oil pressure supplied thereto, thereby establishing a required transmission gear ratio. The changing rate of the rotational speed of the engine and the transmission torque of the driving force transmission apparatus are detected, and the detected transmission torque and the product of the detected engine speed changing rate and a predetermined value are added so that the resulting sum is detected as an engine torque. The torque capacity of each the frictional engagment means is controlled in accordance with the detected sum. Thus, the automatic transmission is improved in follow-up performance and stability.
