초록 ▼

An engine valve operation timing control apparatus having a learning control function determines whether both of an actual phase difference angle and a target value between a crankshaft and a camshaft are almost constant for a predetermined time. When both of the actual phase difference angle and the target value become almost constant for the predetermined time, a control value is learned. A controller outputs the learned value to driving means to find a control value thereafter based on the learned value. As a result, the learning means learns the control value in correspondence with a rate of change of the actual phase difference angle and the control value found by the controller compensates for a disturbance factor. The learning operation is updated every time the actual phase difference angle and the target value converge to a constant value and is repeated when the convergence state continues.

대표청구항 ▼

An engine valve operation timing control apparatus, comprising: a phase control mechanism, provided within a path for transmitting rotations from a crankshaft to a camshaft within an engine, for varying a rotational phase difference between the shafts; driving means for driving said phase control mechanism; operating condition detecting means for detecting a plurality of operating conditions representing operating conditions of said engine; rotational phase difference detecting means for finding an actual phase difference angle between said shafts based on the operating conditions detected by said operating condition detecting means; target value deciding means for deciding a target value of the rotational phase difference based on the operating conditions detected by the operating condition detecting means; and control means for generating a control value for causing said actual phase difference angle to coincide with said target value of the rotational phase difference and for outputting said control value to said driving means; wherein said control means includes first determining means for determining whether said actual phase difference angle is almost constant for a predetermined time, learning means for learning said control value when said actual phase difference angle becomes almost constant for the predetermined time, and a controller for finding a control value thereafter based on the learned value.
