<p><P>PROBLEM TO BE SOLVED: To provide a torque characteristic map correcting device for a friction engagement element of a vehicular transmission by which a torque characteristic map can be learned properly according to an individual difference of vehicles and in addition, the friction engagement element can be controlled optimally based on the learned torque characteristic map. <P>SOLUTION: A torque characteristic map having a characteristic line S for determining a driving current of a solenoid valve from an aimed transmission torque of a clutch is set, and at the same time, two transmission torques T1 and T2 are set as learning points on the torque characteristic map, actual driving currents IA and IB are leaned when the transmission torques of the clutch become transmission torques T1 and T2 respectively, and a characteristic line S is offset while changing an inclination thereof so that the driving currents I1 and I2 at T1 and T2 determined from the characteristic line match the two learning values IA and IB. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
