Control device for internal combustion engine |
摘要 |
A control device 10 for an internal combustion engine 80 includes an injector drive circuit 90 that drives an injector 30 that injects fuel and a temperature detection device that at least detects timing when a temperature condition that the temperature of the injector drive circuit 90 exceeds predetermined temperature is satisfied. The control device 10 includes a heat-generation-suppression control means 104 that performs control for suppressing the heat generation of the injector drive circuit 90. The heat-generation-suppression control means 104 selects, on the basis of a driving state of a vehicle, at least one parameter among an electric current applied to the injector, fuel pressure supplied to the injector 30, the number of revolutions of the internal combustion engine, and voltage from a battery to be boosted and performs control for limiting a value of the selected parameter on the basis of the timing. |
