<P>PROBLEM TO BE SOLVED: To provide a device and method for control of an accumulator fuel injection device, as well as the accumulator fuel injection device, capable of minimally suppressing the power consumption of a battery required for actuation of a pressure control valve at idling-stop control. <P>SOLUTION: The control device is for controlling the accumulator fuel injection device including a common rail, a pressure control valve having a normally open type structure and a fuel injection valve connected to the common rail to inject fuel into cylinders of the internal combustion engine, and includes: an idling-stop control means for performing automatic stop and restart of the internal combustion engine; and a pressure control valve energization current value learning means for learning an energization current value of the pressure control valve during the automatic stop based on a pressure drop value in the common rail during the automatic stop. <P>COPYRIGHT: (C)2013,JPO&INPIT |
