PURPOSE:To improve the extent of controllability, by altering estimation specifications of a driving state estimating device on the basis of a difference between the estimated result of a driving state of engine load or the like and the detected result at the time of stationary drive of an engine, eliminating this difference, and determining a fundamental injection quantity on the basis of the estimated result. CONSTITUTION:In this controller, there is provided with a stationary driving state detecting means C1 which detects a stationary driving state where each variation in suction pipe pressure and opening of a throttle valve is less than the specified value. And, also there are provided with a driving state estimating means C2, estimating a driving state of suction pipe pressure, suction air quantity, load or the like from throttle valve opening and engine speed, and a driving state detecting means C3 detecting a driving state quantity. And, when an internal combustion engine EG is judged to be in the stationary driving state, estimation specifications of the driving state estimating means C2 are altered on the basis of a difference between the estimated result of the driving state and the detected result, whereby learning control is carried out by a learning control means C4 so as to make both accord with each other, and a fundamental injection quantity is determined at a fuel quantity setting means C5 on the basis of the estimated result of the estimating means C2.
