CONTROLLER

摘要

PROBLEM TO BE SOLVED: To deal with a plurality of points of inflections that occur to a driving voltage if characteristic irregularities of a fuel injection valve are to be corrected by a point of inflection.SOLUTION: Provided is a controller for controlling a plurality of fuel injection valves each opening or closing a valve element to control an injection quantity of fuel by controlling a current flowing in a solenoid, a plurality of points of inflections of a voltage or the current occurs in each solenoid, and time from cutoff timing of the voltage or current applied to each solenoid to a specific point of inflection among the points of inflection is set equal among the respective solenoids.
