PROBLEM TO BE SOLVED: To provide a high pressure fuel pump control device of an internal combustion engine capable of improving stability of a driving control of a high pressure fuel pump by limiting a finish timing of a driving signal of the high pressure fuel pump, and driving an actuator within an effective control range of the high pressure fuel pump.SOLUTION: A high pressure fuel pump control device of an internal combustion engine has a fuel injection valve provided to a cylinder, and a high pressure fuel pump for pumping fuel to the fuel injection valve. The high pressure fuel pump has a compression chamber, a plunger for compressing the fuel in the compression chamber, a fuel passage valve provided in the compression chamber, and an actuator for operating the fuel passage valve. A control device has means for calculating driving signals of the actuator so that an emission amount of the high pressure fuel pump is made variable. The means for calculating the driving signals has means for limiting a finish timing of the driving signals of the actuator to a predetermined phase, and/or means for limiting an output timing of the driving means of the actuator within a predetermined phase range. |
