ENGINE KNOCK DETECTION SYSTEMS AND METHODS
A method includes: generating an indicator of present operating conditions of an engine; determining a first amount of noise based on vibration measured during a first plurality of combustion events of a cylinder; storing the first amount of noise and a first value of the indicator in a mapping base...

| description | A method includes: generating an indicator of present operating conditions of an engine; determining a first amount of noise based on vibration measured during a first plurality of combustion events of a cylinder; storing the first amount of noise and a first value of the indicator in a mapping based on a first engine speed and a first engine load; determining the first value of the indicator from the mapping based on a second engine speed and a second engine load; generating a trigger signal when the first value is different than a second value of the indicator; and, when the trigger signal is generated: determining a second amount of noise based on vibration measured during a second plurality of combustion events of the cylinder; and replacing the first amount of noise and the first value in the mapping with the second amount of noise and the second value. |
