PROBLEM TO BE SOLVED: To provide a fuel injection control device capable of learning the values to be learned with high accuracy while increasing the frequency of learning. SOLUTION: The learning of pilot injection is permitted by non-injection deceleration (step S10). An injection amount equivalent to one in pilot injection is calculated as the basic amount of single injection (step S12). Based on the slip ratio between a crankshaft and a driven shaft connected to a drive wheel by a torque converter and the temperature of the hydraulic oil in the torque converter, the correction amount of the injection amount for generating a rotation increasing amount generated by the pilot injection at a reference slip ratio is calculated (step S20). Single injection is performed with the corrected injection amount (step S22). Based on the rotation increasing amount, the actual injection amount is estimated (step S26). Based on the estimated injection amount and the corrected injection amount, the values to be learned are learned. COPYRIGHT: (C)2007,JPO&INPIT
