    • When a throttle is fully open, a maximum torque set value is corrected based on the ratio between the maximum air volume set value under fully-open throttle conditions and the actual maximum air volume detected by an intake air volume meter such as an air flow sensor. Based on the corrected maximum torque set value, both the relation between the degree of accelerator opening and target torque and the relation between the target torque (target air volume) and the degree target throttle opening are corrected. Thus, even when various types of disturbances relating to torque error are generated, such as variations in air density generated in association with variations in temperature or altitude, variations over time such as contaminations of throttle chambers, or difference between machines such as engine bodies or auxiliary machines, it is possible to generate actual torque with respect to a target torque with a high degree of accuracy, while maintaining a desired relation between the degree of accelerator opening and the throttle opening.
    • 当节气门完全打开时,基于在完全打开节流条件下的最大空气体积设定值与由空气流量传感器等进气体积计检测到的实际最大空气量之间的比率来校正最大扭矩设定值 。 基于校正的最大扭矩设定值,校正加速器开度和目标转矩之间的关系以及目标转矩(目标空气量)与目标节气门开度之间的关系。 因此,即使当产生与扭矩误差有关的各种类型的扰动时,例如与温度或高度的变化相关的空气密度的变化,随着时间的变化,例如节流室的污染,或诸如发动机主体或机器之间的差异 辅助机器,可以在保持加速器开度和节气门开度之间的期望关系的同时以高精度产生相对于目标转矩的实际转矩。
