PURPOSE:To secure responsiveness and restrain fluctuation of line pressure due to fluctuation of fuel injection as much as possible by providing a basic line pressure setting means, injection change rate detection means, first correction means, opening change ratio detection means, second correction means and control signal output means. CONSTITUTION:A first correction means (d) corrects a basic line pressure so as to restrain fluctuation of basic line pressure to be set by a basic line pressure setting means (c) according to change ratio of fuel injection detected by an injection change ratio detecting means (a). In the case of large change in fuel injection due to intake pulsations, change in basic line pressure becomes large. The fluctuation of line pressure is, however, restrained effectively by a first correction means through the correction of basic line pressure. Since the opening of throttle valve changes upon acceleration/deceleration, the line pressure can be changed with a good responsiveness through the correction of basic line pressure by a second correction means (e) in response to the throttle valve opening detected by an opening change ratio detection means (b) even if response delay is in setting fuel injection. |
