Patent ID: 7664592

Claim:
A fuel injection control apparatus comprising: a first function of making a determination of whether or not learning conditions are satisfied to allow a fuel injection amount learning to be performed for a fuel injection valve; a second function of directing a commanded fuel injection amount in said fuel injection amount learning to said fuel injection valve if result of said determination is affirmative; a third function of setting an upper limit value of an injection pressure in said fuel injection amount learning; a fourth function of setting a target injection pressure within a range not exceeding said upper limit value in said fuel injection amount learning; a fifth function of setting said injection pressure to said target injection pressure; a sixth function of detecting an actual fuel injection amount of said fuel injection valve; and a seventh function of correcting an amount of fuel injected by said fuel injection valve on the basis of a difference between said commanded fuel injection amount and said actual fuel injection amount at said target injection pressure as a learned correction value.
