PROBLEM TO BE SOLVED: To suppress the generation of cracks at a heat generation body of an EHC at a cold start of an internal combustion engine, and also to suppress the occurrence of a malfunction of an inverter, in a hybrid system in which the electric heating catalyst (EHC) is arranged in an exhaust passage of the internal combustion engine.SOLUTION: A control device of a hybrid system comprises a control part for suppressing an energy amount inputted to an EHC by exhaustion by performing either control for reducing an intake air amount of an internal combustion engine when an energy amount suppression condition being a condition that an energy amount inputted to the EHC should be suppressed is established, or control for reducing an air-fuel ratio of a mixture air without reducing the intake air amount of the internal combustion engine. At a cold start of the internal combustion engine, when a supply power suppression condition being a condition that power supplied to an inverter from a generator should be suppressed is established in addition to the input energy amount suppression condition, the control part selects and executes the control for reducing the intake air amount of the internal combustion engine. |
