PROBLEM TO BE SOLVED: To increase fuel injection control accuracy, by selectively using an actual measurement value and an estimated value of fuel injection pressure based on fuel injection timing of a fuel injection means in a fuel injection controlled variables calculating means. SOLUTION: A determination is made whether or not an injection is in a timing t120 for calculating a second timing t2 injecting fuel (S41). When the result is Yes, the second timing t2 for injecting fuel is calculated (S42). A time T2 is required for calculation of a fuel injection amount based on an actual measurement value of which fuel injection pressure can be obtained, at a timing t1. A determination is made whether a timing after the time T2 of the first timing t1, is earlier than the second timing t2 that is the fuel injection time (S43). When the result is earlier (later), a flag is set to be OFF (ON). When the flag is ON, the fuel injection amount is calculated by an estimated value of the fuel injection pressure (S46). When the flag is OFF, the fuel injection pressure is actually measured at the first timing t1 (S48), and then the fuel injection amount is calculated by the actual measurement value (S50). |
