发明名称 KNOCK SENSOR NETWORK SYSTEMS AND METHODS FOR CHARACTERIZING NOISES
摘要 A method of analyzing a noise signal includes receiving, via a local engine control unit (ECU), a noise signal sensed by a knock sensor disposed in a reciprocating device. The method further includes processing the noise signal via at least one of the local ECU, a remote ECU, or an external system. The processing includes preconditioning the noise signal to derive a preconditioned noise signal, and applying an ADSR envelope to the preconditioned noise signal. The processing additionally includes extracting tonal information from the preconditioned noise signal and creating a fingerprint of the noise signal based on the ADSR envelope, the tonal information, or a combination thereof.

主权项 1. A method of analyzing a noise signal, comprising: receiving, via a local engine control unit (ECU), a noise signal sensed by a knock sensor disposed in a reciprocating device; processing the noise signal via at least one of the local ECU, a remote ECU, or an external system, wherein the processing comprises: preconditioning the noise signal to derive a preconditioned noise signal;applying an ADSR envelope to the preconditioned noise signal;extracting tonal information from the preconditioned noise signal; andcreating a fingerprint of the noise signal based on the ADSR envelope, the tonal information, or a combination thereof.
