PROBLEM TO BE SOLVED: To realize line pressure control suitable for transmission input torque in a consideration of auxiliary equipment actuating torque. SOLUTION: Engine output torque TQ=K1×(Qa -Qf )/Ne (S2;Qf is a friction part intake air flow rate) is computed from an intake air flow rate Qa and engine speed Ne . At the time of vehicle stop (VSP=0), transmission input torque Tp =K2×Ne<2> is computed (S3, S6) from the engine speed Ne, and accordingly, auxiliary equipment actuation torque Tphos =Tq -Tp is computed (S7). Thereafter, on the assumption that this auxiliary equipment actuating torque does not change for a certain period of time after starting, the auxiliary equipment actuating torque Tphos is subtracted from engine output torque Tq , and engine output torque after correction Tqsen =Tq -Tphos is computed (S13). Thereafter, line pressure of a transmission is computed and controlled in accordance with the engine output torque after correction Tqsen . |
