Abstract
A fuel pump controller performs a feedback control of an actual fuel pressure of a feed pump to a command fuel pressure which is from an external element. The pump controller changes a gain for the feedback control to a value larger than a minimum value of the gain in response to an acceleration command information which is to accelerate a vehicle by using an internal combustion engine.
