Title: Variable valve timing control device for internal combustion engine
Inventor: TAKEMURA YUICHI
IPC: F02D45/00
Filed: 2009-04-23
Abstract: <P>PROBLEM TO BE SOLVED: To reduce the influence of the deviation of a holding duty learning value on the stability of valve timing control, in a variable valve timing device for an internal combustion engine.  <P>SOLUTION: The control characteristic of the variable valve timing device (VCT) is a nonlinear control characteristic having high response regions having high VCT response speeds at both sides of a low response region having a low VCT response speed, and a true holding duty exists in the low response region. The true holding duty exists in the vicinity of the high response region at an advance side due to an influence of cam torque. Therefore, when the learning value of the holding duty is slightly deviated to the advance side, there is a possibility of causing overshoot or the like. By this, a value with a holding duty offset by a predetermined amount in a retard direction being a direction separated from the high response region at the advance side within the low response region is learned as the holding duty learning value. At this time, the offset of a holding controlled variable is set so that the holding duty learning value reaches a value within a predetermined range in the vicinity of the center of the low response region.  <P>COPYRIGHT: (C)2011,JPO&INPIT
