CAMSHAFT AND CRANKSHAFT POSITION CORRELATION SIMULATION METHODS AND SYSTEMS |
摘要 |
A system designed to simulate an internal combustion engine having improper valve timing is provided. The purpose of the simulation system is to calibrate and/or validate a proprietary cam-crank correlation diagnostic algorithm. The simulation system includes a simulator module that communicates with crankshaft and camshaft position sensors and an engine control module. The simulator module includes: a first selector that selects a shift value for shifting a periodic signal; and a modification module that receives a camshaft position signal from the camshaft position sensor and that generates a modified camshaft position signal based on the crankshaft position signal and the shift value.
