Correcting device for fuel injection control device

Abstract

Abstract PURPOSE:To attain a stable engine speed, by constituting a device correcting a depressing amount of an accelerator pedal by a correction value, obtained in the time of fixed speed control, and controlling fuel injection on the basis of the depression amount after it is corrected. CONSTITUTION:A speed of a Diesel engine A is detected by a speed detecting means D, and a deviation of the speed from a predetermined value is obtained by a fixed speed deviation detecting means E. In the time of fixed speed control, a virtual control amount arithmetic means F obtains a virtual control amount of an accelerator pedal for obtaining a fixed speed fuel injection quantity in accordance with the above described deviation of the speed. And a deviation of said virtual control amount from the reference value of a reference value setting means H is calculated by a correcting means G. The control amount is corrected by this deviation, and a fuel injection amount of the Diesel engine is controlled through a control means B. Accordingly, even if the engine provides unevenness of the characteristic or the like and aged deterioration, a rapid change of the engine speed is eliminated when the engine is transferred from a fixed speed control to a control based on an accelerator control.
