PROBLEM TO BE SOLVED: To precisely estimate pressure of an intake/exhaust system at low cost. SOLUTION: A cylinder intake air quantity Qac, a cylinder intake EGR quantity Qec, an intake temperature Ta, an exhaust temperature Te, and a volume efficiency equivalent value Kin are inputted (S1) as determined in separate routines, and an intake pressure Pm is determined based on these values (S2).
