摘要：A control system of an internal combustion engine includes an electroniccontrol unit (41). The electronic control unit (41) is configured to: (i) obtain a detectionvalue of a fuel pressure sensor (28) at fixed sampling time intervals; (ii) calculate a centerfuel pressure value of a pulsation of the fuel pressure, based on at least a first latest fuelpressure value and a second latest fuel pressure value as detection values of the fuelpressure sensor (28), (iii) calculate an amplitude of the pulsation of the fuel pressure,based on at least the second latest fuel pressure value and the first latest fuel pressurevalue; (iv) calculate an initial phase of the pulsation of the fuel pressure, based on at leastone of the second latest fuel pressure value and the first latest fuel pressure value, and(v) predict a fuel pressure value corresponding to the crank angle, based on apredetermined formula.
