<P>PROBLEM TO BE SOLVED: To firstly learn a waviness error and learn a τQ error after the completion of the learning of the waviness error. <P>SOLUTION: A fuel-injection control device can learn both of the waviness error and the τQ error with high accuracy by separately learning them. The waviness error is an error of the fuel-injection amount caused by pulsation of fuel pressure during multi-stage injection. The τQ error is an error of the fuel injection amount caused by a setting deviation of injector energization time with respect to a command injection amount. <P>COPYRIGHT: (C)2012,JPO&INPIT |
