CPS KNOCK DETECTION SYSTEM |
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.
