ENGINE CRANKSHAFT POSITION RECOGNITION AND TRACKING METHOD APPLICABLE TO CAM AND CRANKSHAFT SIGNALS WITH ARBITRARY PATTERNS |
摘要 |
A method and system for providing data representing crankshaft position. For each rising edge of the crankshaft signal, a position value and a factor val ue are stored in a look-up table. Cam and crankshaft signals are used to locate an initial crankshaft position. This initial position value is used as a pointer to the look-up table, and incremented with each rising pulse of the crankshaft signal. Data from the table is used to extrapolate crankshaft position from crankshaft signal values to a desired resolution in degree ang le units.
