Variable cam timing control system and method |
摘要 |
A system and method for measuring and controlling cam timing of an internal combustion engine uses a filtering method based on a number of equally spaced teeth mounted on the camshaft. The filtering method specifically removes certain oscillations caused by camshaft torsional effects. The filtering method also specifically removes oscillations due to production variations. These oscillations are removed with minimal effect on closed loop system response.
