PURPOSE:To properly set line pressure according to the presence of auxiliary machine drive in the case of a system in which the line pressure of an automatic transmission is determined on the basis of the air intake amount of an engine. CONSTITUTION:In an idle operation state in which the feedback control of a rotary speed is conducted (S2, S3), first, a reference air quantity QSTD is sought according to water temperature Tw that is the set parameter of a target rotary speed (S4). Hereupon, a variation QDIF between the reference air quantity QSTD and an intake air quantity Q detected actually is operated (S5). Next, the variation QDIF is converted into a correction air quantity COQ equivalent to an auxiliary machine load drive amount (S6), the intake air quantity Q is corrected by the correction air quantity COQ (S7), and engine generation torque PRS is operated on the basis of a corrected intake air quantity Qa (S8), and line pressure PL is determined from the torque PRS. |
