Abstract:
1. A fuel injection controller comprising: a learning means for learning and storing a deviation amount relative to a reference of an operational characteristic of an actuator, which is used for a fuel injection control for an internal combustion engine, as a deviation amount at a representative point with respect to each region which has been plurally divided with parameters used for the fuel injection control; an operating means for operating the actuator in such a manner as to compensate the deviation amount which is obtained by an interpolating process by use of the stored deviation amount in a case that actual value of parameters are consistent with no representative point; a determining means for determining whether the deviation amount converges at the representative point which is used for the interpolating process and is in a region where the actual value of parameters does not exist; and a substituting means for substituting the deviation amount at the representative point in a region in which the actual value of parameters exists for the deviation amount which has not converged in a case that the determining means determines that the deviation amount has not converged.
