ABSTRACT:
There is provided with an ECU for estimating an unburned fuel amount (HC) emitted from an engine after fuel combustion or a temperature of a DPF based upon a required engine operating condition as a control target value. An exhaust gas temperature sensor for detecting a temperature of an exhaust gas emitted directly from the engine is provided. A program for compensating for an estimation error in regard to an estimation value of the unburned fuel amount estimated from the required engine operating condition, that is, an operating condition difference amount between the required engine operating condition and an actual engine operating condition, based upon an engine exhaust gas temperature detected from the exhaust gas temperature sensor is provided.
