An intake air flow rate control method and system comprises a circuit for determining a basic control ratio corresponding to an engine or engine coolant temperature and a plurality of circuits for correcting the basic control ratio corresponding to engine driving conditions and engine load conditions. Additionally, the system discriminates among engine driving condition to determine whether feedback control or open loop control is to be carried out. A circuit for discriminating among the engine driving conditions improves response characteristic to reduce lag that tends to occur between feedback control and open loop control when control operation is switched between feedback control and open loop control. |
