    • An intake passage upstream of a throttle valve is divided into a plurality of intake divided-flow conduits, and air flow meters are arranged in the respective intake divided-flow conduits. The throttle opening is obtained, and a throttle valve passing-through air amount, which is an amount of air passing through the throttle valve, is calculated on the basis of the throttle opening. Each air flow meter-detecting intake air amount, which is an intake air amount to be detected by the air flow meter, assuming that air flows through each intake divided-flow conduit by a part of the throttle valve passing-through air amount, the part being determined by a divided-flow ratio of the corresponding intake divided-flow conduit, is estimated, and a total value of the estimated air flow meter-detecting intake air amounts is then estimated. The engine is controlled on the basis of the total air flow meter-detecting intake air amount.
    • 在节流阀上游的进气通道被分成多个进气分流管道,并且在相应的进气分流管道中设置空气流量计。 获得节气门开度,并且基于节气门开度计算作为通过节流阀的空气量的节气门通过空气量。 每个空气流量计检测吸入空气量,其是由空气流量计检测的进气量,假设空气通过节流阀通过空气量的一部分流过每个进气分流管道, 估计由相应的进气分流管道的分流比确定的部分,然后估计估计的空气流量计检测进气量的总值。 基于总的空气流量计检测进气量来控制发动机。
