Abstract
A system for a vehicle includes a filtering module and an indicated work 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 crankshaft position sensor generates the crankshaft position signal based on rotation of the toothed wheel. The indicated work module generates an indicated work for a combustion cycle of a cylinder of an engine based on squares of first and second ones of the engine speeds and outputs the indicated work.
