Abstract
A control apparatus is provided to control a fuel injection apparatus. The fuel injection apparatus includes an accumulator that accumulates high-pressure fuel, at least one injector that injects the high-pressure fuel accumulated in the accumulator into a cylinder of an internal combustion engine, and a pressure sensor that senses fuel pressure in the accumulator and outputs a signal indicative of the sensed fuel pressure. The control apparatus includes an estimator, a determiner, and a setter. The estimator estimates an actual injection duration of the injector. The determiner determines, during the actual injection duration estimated by the estimator, a value of the fuel pressure in the accumulator based on the signal output from the pressure sensor. The setter sets a manipulated variable for controlling fuel injection quantity of the injector based on the value of the fuel pressure determined by the determiner.
