Abstract:
An apparatus for estimating temperatures of a vehicle includes an acquirer to acquire an engine correlated temperature correlated with the temperature of an engine when the engine is stopping. The apparatus further includes an estimator to estimate a catalyst temperature of a catalyst disposed in an exhaust system of the engine, based on an inlet gas temperature estimated through a first-order lag operation with an exhaust-manifold temperature at a stop of the engine as an initial temperature and the engine correlated temperature as a target temperature.
