Abstract
A method for early detection of a stochastic preignition (SPI) in an internal combustion engine includes monitoring sensor data from a sensor that is coupled to the internal combustion engine of a vehicle, determining whether a SPI event will occur using the sensor data and a Hankel Alternative View of Koopman (HAVOK) model, and commanding the vehicle to take a corrective action before the SPI event occurs to prevent the SPI event from happening in response to determining that the SPI event will occur.
Claims20
A method for early detection of a stochastic preignition (SPI) in an internal combustion engine, comprising:
- monitoring sensor data from a sensor that is coupled to the internal combustion engine of a vehicle;
- determining whether a SPI event will occur using the sensor data and a Hankel Alternative View of Koopman (HAVOK) model;
- and
- commanding the vehicle to take a corrective action before the SPI event occurs to prevent the SPI event from happening in response to determining that the SPI event will occur.
A tangible, non-transitory, machine-readable medium, comprising machine-readable instructions, that when executed by a processor, cause the processor to:
- monitor sensor data from a sensor that is coupled to an internal combustion engine of a vehicle;
- determine whether a stochastic preignition (SPI) event will occur using the sensor data and a Hankel Alternative View of Koopman (HAVOK) model;
- and
- commanding the vehicle to take a corrective action before the SPI event occurs to prevent the SPI event from happening in response to determining that the SPI event will occur.
A system, comprising:
- an internal combustion engine;
- a sensor coupled to the internal combustion engine;
- a controller in communication with the sensor, wherein the controller is programmed to:
- monitor sensor data from the sensor that is coupled to the internal combustion engine of a vehicle;
- determine whether a stochastic preignition (SPI) event will occur using the sensor data and a Hankel Alternative View of Koopman (HAVOK) model;
- and
- commanding the vehicle to take a corrective action before the SPI event occurs to prevent the SPI event from happening in response to determining that the SPI event will occur.
