摘要：PURPOSE:To set a proper line pressure corresponding to the engine output torque by installing a compensation value setting means which sets a compensation value for compensating an error of intake air flow attributable to a draft of intake air in a suction passage on the basis of engine speed and engine load. CONSTITUTION:A compensation value setting means C sets a compensation value for compensating a detection error of intake air flow attributable to a draft of intake air on the basis of engine speed to be detected by an engine speed detecting means A and engine load to be detected by an engine load detecting means B. An intake air flow compensating means D compensates an intake air flow F on the basis of the compensated value set by the compensation value setting means C. Then line pressure is set by a line pressure setting means E on the basis of this compensated intake air flow. With this constitution, any effect of the draft of the intake air flow is eliminated, thus accurate line pressure is set in every operating area.
