Abstract
The operational state of the engine is detected and the target value of the motor is computed corresponding to the operational state (step S1); a current value of the motor is obtained (step S2); and the width of a stop target area that is a determination parameter is selected based on the target value and the current value (step S3). The stop target area is obtained based on the selected width of the stop target area and the target value (step S4). If the current value falls within the stop target area, then a motor control signal is determined so as to maintain the current value, and if the current value is beyond the stop target area, then the motor control signal is determined so as to draw the current value toward the target value (steps S6 and S7).
Claims5
A control device for 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 outputting the same as control information;
- target value computing means for computing the target value of the operational state of the control motor according to the control information outputted from the control information output means;
- current value detecting means for detecting a current value of the operational state of the control motor;
- motor control signal determining means for generating a motor control signal for controlling a drive applied to the control motor, based on the target value and the current value;
- and
- drive means for driving the control motor based on the motor control signal,
- wherein the motor control signal determining means has a parameter for determining the motor control signal to be outputted, and the value of the parameter is set by selecting one from among a plurality of values based on the control information.
