    • Embodiments of the present invention include an engine control method for controlling an engine having an accessory. In the method, a relationship between a torque of the accessory and a controlled variable corresponding to each rotational speed of the engine is stored in advance. An estimated value of the controlled variable is calculated based on a calculated value of the torque of the accessory and the engine rotational speed by reference to the said relationship. A command value of the controlled variable is calculated based on at least one of the engine rotational speed, opening of a throttle, opening of an accelerator and an air supply pressure. A calculated difference is determined by comparing the estimated value of the controlled variable and the command value of the controlled variable.
    • 本发明的实施例包括用于控制具有附件的发动机的发动机控制方法。 在该方法中,预先存储附件的扭矩与对应于发动机的每个转速的受控变量之间的关系。 通过参照所述关系,基于附件的转矩和发动机转速的计算值来计算控制变量的估计值。 基于发动机转速,节气门开度,加速器开度和供气压力中的至少一个来计算控制变量的指令值。 通过比较受控变量的估计值和受控变量的指令值来确定计算出的差值。
