To precisely control the charge of a gas into a plurality of cylinders with a simple structure in an internal combustion engine in which a variable valve control is performed.
A sampling value, mlaRtx is obtained by sampling the measurement signals, mla of the charge amount sensors 14 and 15 based on a sampling rate (f). A first interval R1-Syn for a first cylinder is decided, and the sampling values, mlaR1-Syn therein are accumulated to obtain the sum, AW1 of the first sampling values. Further, the number of the first sampling values, mlaR1-Syn in the first measurement interval R1-Syn is counted to obtain a first discrete value Z1. Then, a first air amount, mlm1 charged into the first cylinder is obtained by the formation of division of the first sampling value AW1 by the first discrete value Z1.
