CPC F02D 11/105 (2013.01) [F02D 41/1497 (2013.01); F02D 2200/0404 (2013.01); F02D 2200/101 (2013.01); F02D 2200/1004 (2013.01)] | 5 Claims |
1. An electronic throttle control method by an electronic control throttle device that performs opening and closing control of the throttle while an electronic control unit generates a control signal based on an input data signal, the method, by the electronic control unit, comprising:
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 the control signal for the throttle by using a sum of the proportional torque and the integral torque as a value of a torque command.
