An engine ECU executes a program including the step of detecting an engine coolant temperature (THW), the step of selecting a map for a warm state as the map for calculating a fuel injection ratio (or a DI ratio) r when the engine coolant temperature (THW) is equal to or higher than a temperature threshold value (THW(TH)) (YES in S 110 ), the step of selecting a map for a cold state as the map for calculating the fuel injection ratio (or the DI ratio) r when the engine coolant temperature (THW) is lower than the temperature threshold value (THW(TH)) (NO in S 110 ), and the step of calculating the fuel injection ratio between the in-cylinder injector and the intake manifold injector (or the DI ratio) r based on the engine speed, load factor, and the selected map.
