Time delay compensation for thermal mass flow sensor |
摘要 |
<p>An intake air-flow rate detecting apparatus of an internal combustion engine according to the present invention has a thermal air-flow sensor for detecting an intake air-flow rate of the internal combustion engine, and a response lag compensator for compensating for a response lag of the air-flow sensor, using a first-order lag element concerning a heat release amount in the air-flow sensor. Since the response lag process is carried out on the dimension of the heat release amount, the response lag of the air-flow sensor can be compensated for with accuracy and the response lag of the thermal air-flow sensor can be compensated for with high accuracy.</p> |
