<p>PROBLEM TO BE SOLVED: To set oil pressure adapted to input torque to improve the durability of a friction engaging device. SOLUTION: An input torque to an automatic transmission is estimated by plural input torque estimating means (steps 8, 9, and 9-1), to decide engaging pressure by a first engaging pressure deciding means based on input torque estimated by any input torque estimating means (step 8). In the case, wherein the abnomality of an input torque estimated value by any input torque estimating means (step 8) is judged by this abnormality judging means (steps 2-6), engaging pressure is decided by a second engaging pressure deciding means (steps 9 and 9-1) based on input torque estimated by the other input torque estimating means (steps 9 and 9-1).</p> |
