    • 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.
    • 提供控制装置来控制燃料喷射装置。 燃料喷射装置包括:蓄积器,其积存高压燃料;至少一个喷射器,其将累积在蓄能器中的高压燃料喷射到内燃机的气缸中;以及压力传感器,其感测蓄能器中的燃料压力; 输出表示感测到的燃料压力的信号。 控制装置包括估计器,确定器和设定器。 估计器估计注射器的实际注射持续时间。 在由估计器估计的实际喷射持续时间期间,确定器基于从压力传感器输出的信号确定累加器中的燃料压力的值。 设定器基于由确定器确定的燃料压力的值来设定用于控制喷射器的燃料喷射量的操作变量。
