  • Electronic control method for throttle and electronic control throttle device
    Patent number: 11719171
    Abstract: An electronic control method for a throttle by an electronic control throttle device that controls the throttle while an electronic control unit generates a control signal based on an input data signal. The method may include calculating an engine rotation speed deviation from a difference between an engine rotation speed and an input engine rotation speed command, calculating an engine rotational acceleration based on the engine rotation speed, obtaining a proportional torque from a product of the engine rotation speed deviation and a predetermined coefficient, obtaining an integral torque by integrating a value obtained by subtracting a product of the engine rotational acceleration and the predetermined coefficient from the product of the engine rotation speed deviation and the predetermined coefficient, and generating a control signal for the throttle by using a sum of the proportional torque and the integral torque as a value of a torque command.
