<P>PROBLEM TO BE SOLVED: To provide a high-pressure fuel pump control device for an internal combustion engine capable of controlling completion timing of drive signal of a high-pressure fuel pump, and of improving stability of drive control of the high-pressure fuel pump by driving an actuator in a valid control range of the high-pressure fuel pump. <P>SOLUTION: This high-pressure fuel pump control device for an internal combustion engine includes a fuel injection valve provided in a cylinder and the high-pressure fuel pump pressurizing and feeding fuel to the fuel injection valve. The high-pressure fuel pump includes a pressurizing chamber, a plunger pressurizing fuel in the pressurizing chamber, a fuel passage valve provided in the pressurizing chamber, and an actuator operating the fuel passage valve. The control device includes a means for calculating drive signal of the actuator to make delivery quantity of the high-pressure fuel pump variable. The means for calculating the drive signal includes a means controlling completion timing of the drive signal of the actuator to prescribed phase and/or a means controlling output timing of the drive signal of the actuator in a prescribed phase range. <P>COPYRIGHT: (C)2010,JPO&INPIT |
