Cam synchronization algorithm for engine with variable cam timing |
摘要 |
A system and method for controlling first and second phase shiftable camshafts in a variable cam timing engine is provided. The method includes determining when the first camshaft is moving toward a first scheduled phase angle with respect to the crankshaft with a larger camshaft angular positioning error than the second camshaft. Finally, the method includes slowing down the first camshaft so that synchronized camshaft positioning can be better achieved.
