To materialize highly precise fuel injection control by considering difference of contribution of fuel injection rates, in a direct injection type internal combustion engine.

Transition period fuel injection rate compensation correction amount dQ1 (S120, S124) and whole close period fuel injection rate compensation correction amount dQ2 (S122, S126) are calculated with separating to valve open and close drive transition period and full open period of a fuel injection valve according to difference of contribution of fuel injection rate. The transition period fuel injection rate compensation correction amount dQ1 and the full open period fuel injection rate compensation collection amount dQ2 are converted to fuel injection rate compensation correction time dTh (S130) based on estimated fuel injection rate rqi (S128) and collection of open valve timing compensation correction time dTt (S132, S134) and base fuel injection time Tbs is executed (S136). Consequently, a target is achieved.
