More Information
Summary:A knocking sensor (18) detecting vibration of an engine body (1) and a pressure sensor (19) detecting a pressure of a combustion chamber (5) are provided. A value representing the knocking strength is acquired from output values of the pressure sensor (19). Weights of a neural network are learned using a value representing the vibration of the engine body (1) detected by the knocking sensor (18) as an input value of the neural network and using the acquired value representing the knocking strength as training data. The value representing the knocking strength is estimated from the output values of the knocking sensor (18) by using the learned neural network.
