The invention pertains to a control device for a common rail fuel injection device that avoids simultaneous driving of a pressurized fuel feed pump and a pressure reducing valve and enables proper regulations to a common rail pressure. The common rail fuel injection device includes a first flow rate regulating valve and a second flow rate regulating valve (12E, F) for regulating a delivery volume of the pressurized fuel feed pump (12) that feeds pressurized fuel to a common rail (13), and also includes the pressure reducing valve (18) for reducing the common rail pressure. The control device includes a first drive controlling unit (21) that controls an electromagnetic driving unit (32) for the second flow rate regulating valve (12F) and an electromagnetic driving unit (33) for the pressure reducing valve (18), and a second drive controlling unit (22) that controls an electromagnetic driving unit (31) for the first flow rate regulating valve (12E). The first drive controlling unit (21) prohibits a drive instruction from being sent to the second flow rate regulating valve (12F) when the first drive controlling unit sends a drive instruction to the pressure reducing valve (18). |
