摘要： A control system includes a cylinder pressure sensor (CPS) that senses a cylinder pressure of an engine and generates a CPS signal based on the cylinder pressure. A CPS failure detection module selectively generates a failure signal based on characteristics of the CPS signal in a knock frequency range. A status detection module generates a CPS status signal based on the CPS signal and the failure signal.

摘要： A control system for an engine includes a heat-release rate (HRR) module, a first filter module, a second filter module, an auto-ignition energy determination module, and a corrective action module. The HRR module generates an HRR signal based on in-cylinder pressures of a cylinder of the engine. The first filter module generates a first filtered HRR signal indicative of a first HRR due to combustion in the cylinder by filtering the HRR signal. The second filter module generates a second filtered HRR signal indicative of a second HRR due to auto-ignition in the cylinder by filtering one of the HRR signal and the first filtered HRR signal. The auto-ignition energy determination module determines an auto-ignition energy of the cylinder based on the first and second filtered HRR signals. The corrective action module selectively adjusts auto-ignition of the engine based on the auto-ignition energy. A related method is also provided.

摘要： A control system includes a speed determination module and a profile estimation module. The speed determination module determines previous engine speeds based on a predetermined profile of a crankshaft position sensor and previous pulse times corresponding to teeth on the crankshaft position sensor. The profile estimation module performs data fitting to determine an estimated profile of the crankshaft position sensor based on the previous pulse times and the previous engine speeds. The speed determination module determines present engine speeds based on the estimated profile and present pulse times corresponding to the teeth on the crankshaft position sensor.
