Control apparatus and method for vehicle having internal combustion engine.

摘要

A control apparatus is provided for an internal combustion engine that causes a first emission and a second emission to be generated upon combustion of a fuel, wherein an amount of the second emission in an exhaust gas increases as an operating state of the engine is changed so as to reduce an amount of the first emission in the exhaust gas, and wherein an emission control device is provided in an exhaust passage so as to purify an exhaust gas by reducing at least one of the first emission and the second emission. The control apparatus comprises emission control capability determining means for determining an emission control capability with which the emission control device reduces an amount of one of the first emission and the second emission, and operating state changing means for changing an operating state of the internal combustion engine based on the determined emission control capability.
