Abstract:
A control device for controlling a control motor of an internal combustion engine which follows a target value that changes in response to an operational state of the internal combustion engine, the control device comprising:control information output means for detecting the operational state of the internal combustion engine and turning it into control information; target value computing means for obtaining the target value of the control motor corresponding to the control information outputted from the control information output means; current value detecting means for detecting a current value of the control motor; motor control signal determining means for generating a motor control signal for controlling a drive of the control motor, based on the target value and on the current value; drive means for driving the control motor based on the motor control signal; and control state information determining means for generating control state information indicating a change in the operational state of the internal combustion engine, based on a change in the control information outputted from the control information output means; wherein the target value computing means corrects the control information based on the control state information, and obtains the target value corresponding to the corrected control information; and wherein the internal combustion engine is in one of four operational states, the four operational states being an acceleration state, a steady state after acceleration, a deceleration state, and a steady state after deceleration, and wherein the control state information determining means identifies the state of the internal combustion engine so as to generate the control state information.
