Abstract
A device for correcting injector characteristics includes: an injector-characteristic detection unit that outputs a selection signal by detecting drive characteristics of injectors in response to a selection control signal; a selection control unit that outputs the selection control signal for selecting a factor for deviation correction to the injector-characteristic detection unit; a selection confirmation unit that confirms a variation value of the factor corresponding to the selection signal; a deviation correction unit that calculates a deviation compensation value corresponding to the injector characteristics in response to an output signal of the selection confirmation unit, and thus output a correction signal; a control unit that generates a correction clock in response to the correction signal; and an output drive unit that controls driving of the injectors in response to the correction clock.
