APPARATUS FOR ESTIMATING TEMPERATURES OF VEHICLE |
| 摘要 |
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. |

1. An apparatus for estimating temperatures of a vehicle, the apparatus comprising:
an acquirer to acquire an engine correlated temperature correlated with a temperature of an engine when the engine is stopping; and an estimator to estimate a catalyst temperature of a catalyst based on an inlet gas temperature, the inlet gas temperature being 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, the catalyst being disposed in an exhaust system of the engine. |
