摘要：
A controlling apparatus of a variable capacity type fuel pump, for preventing noises caused due to drive of the fuel pump and noises caused due to drive of injectors from overlapping or duplicating each other in the timing thereof, wherein signals for driving the pump are reduced, or the timing thereof is shifted forward/backward, within a specific timing where the overlapping can be expected, or a specific timing where they are determined to overlap or duplicate with each other.
