摘要： A knock sensor diagnostic system may include a knock sensor. A bias circuit applies a bias voltage to the knock sensor. An input circuit receives an input signal based on the bias voltage. A control module indicates a short circuit associated with the knock sensor based on the input signal. A knock sensor diagnostic system may also or alternatively include a signal generator that generates and applies a test signal with a predetermined frequency to the knock sensor. Another input circuit receives another input signal that is based on the test signal. A control module indicates an open circuit associated with the knock sensor based on the other input signal.

摘要： A knock detection module for an engine comprises a statistics storage module and a processing module. The statistics storage module stores M times N vibration profiles corresponding to M zones of operation of the engine and N cylinders of the engine, wherein M and N are integers greater than one. The processing module determines in which one of the M zones the engine is operating and determines whether knock has occurred for one of the N cylinders by comparing measured vibration data with a selected one of the vibration profiles corresponding to the one of the M zones and the one of the N cylinders.

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.
