Control device for common rail fuel injection device

A control device for a common rail fuel injection device, the common rail fuel injection device including a first flow rate regulating valve and a second flow rate regulating valve configured to regulate a delivery volume of fuel from a pressurized fuel feed pump that feeds pressurized fuel to a common rail, and also including a pressure reducing valve configured to reduce a pressure of the common rail, said control device comprising:

• a first drive controlling unit configured to control a first electromagnetic driving unit of the second flow rate regulating valve and a second electromagnetic driving unit of the pressure reducing valve;
• and
• a second drive controlling unit configured to control a third electromagnetic driving unit of the first flow rate regulating valve,
• the first drive controlling unit being configured to prohibit a drive instruction from being sent to the second flow rate regulating valve when the first drive controlling unit sends a drive instruction to the pressure reducing valve,
• wherein the first drive controlling unit is configured to refrain from driving the pressure reducing valve until the second flow rate regulating valve finishes its movement, if the first drive controlling unit sends the drive instruction to the second flow rate regulating valve and also is required to drive the pressure reducing valve.
