  • Engine control apparatus and engine control method
    Patent number: 9341125
    Abstract: When an accelerator operation amount is 0, a throttle actuator is controlled by means of isochronous control by using a second throttle operation amount (?tps2) for the isochronous control, and, on the other hand, when the accelerator operation amount is not 0, the throttle actuator is controlled by means of droop control by using a first throttle operation amount (?tps1) for the droop control. When an engine rotation speed is equal to or lower than a LOW rotation speed, larger one of the first and second throttle operation amounts (?tps1 and ?tps2) is used, and when the engine rotation speed is equal to or higher than a HIGH rotation speed, smaller one of the first and second throttle operation amounts (?tps1 and ?tps2) is used, to thereby control the throttle actuator by means of the isochronous control.
