摘要：The present invention relates to a device for correcting the characteristics of an injector and, more specifically, to a technique for automatically selecting a voltage or an electric current for checking the closing point of an injector in a driving semiconductor during the drive of the injector for spraying fuel. The present invention comprises: a detection part of the characteristics of an injector for detecting the driving characteristics of an injector in response to a selection control signal and outputting a selection signal; a selection control part for outputting a selection control signal for selecting a factor for correcting variations in the characteristics of the injector to the detection part of the characteristics of an injector; a selection checking part for checking the change value of the factor corresponding to the selection signal; a variation correcting part for calculating a variation correction value corresponding to the characteristics of the injector and outputting a correction signal according to the output of the selection checking part; a control part for generating a correction clock in response to the correction signal; and an output driving part for controlling the drive of the injector in response to the correction clock.
