Abstract

Una unidad de control electrónico (ECU) de motor ejecuta un programa que incluye los pasos de: detectar una magnitud de la vibración de un motor (S102), detectar una forma de onda de la vibración del motor basándose en la magnitud (S104), calcular un coeficiente de correlación K en el caso en donde el NE de velocidad del motor es más pequeño que un valor de umbral NE (1), utilizando la suma de valores que se determinan individualmente restando un valor de referencia positivo de una magnitud relacionada con un modelo de forma de onda de detonación, como un área S del modelo de forma de onda de detonación, y calcular el coeficiente de correlación K, en el caso en donde el NE de velocidad del motor no es más pequeño que el valor de umbral NE (1), utilizando el área S del modelo total de forma de onda de detonación (S114), y determinar si ha ocurrido o no la detonación utilizando el coeficiente de correlación K (S120, S124). El coeficiente de correlación K se calcula dividiendo por el área S la suma de las diferencias que son en forma individual la diferencia entre la magnitud relacionada con la forma de onda de la vibración y la magnitud relacionada con el modelo de forma de onda de detonación.
