Provided are a load detection means (2a) which detects the load on the internal combustion engine (10), and an injection amount calculation means (5) which calculates the in-cylinder injection amount injected from an in-cylinder injection valve (11). Also provided are a first control means (2e) which performs first control for raising the frequency of fuel injection from the in-cylinder injection valve (11) when the in-cylinder injection amount has decreased, and a second control means (6) which performs second control for increasing the fuel injection amount from a port injection valve (12) when the in-cylinder injection amount has decreased.
