    摘要: A control module includes a sensor input, a discrete signal control module and a processor. The sensor input receives a sensor signal. The discrete signal control module includes a discrete signal input and selectively generates a digital signal based on the sensor signal. A processor includes a time-based input, a digital signal input, and an analog input. The time-based input and the analog input are in communication with the sensor input. The digital signal input is in communication with the discrete signal control module. The processor selectively receives one of the sensor signal and the digital signal via one of the time-based input, the digital signal input and the analog input.

    摘要: A system for a vehicle includes a filtering module, an indicated mean effective pressure (IMEP) determination module, and a stuck mechanism indicator module. The filtering module generates engine speeds based on positions of teeth of a toothed wheel that rotates with a crankshaft and based on a crankshaft position signal generated by a crankshaft position sensor. The IMEP determination module determines an IMEP for a combustion cycle of a cylinder of an engine based on squares of first and second ones of the engine speeds during the combustion cycle. The stuck mechanism indicator module selectively diagnoses a fault in a variable valve lift (VVL) mechanism of the cylinder based on the IMEP.
