Abstract

Una ECU del motor ejecuta un programa que incluye los pasos de: calcular (S200) un valor absoluto ?S( 1) de la desviacion de la forma de onda de la vibracion detectada por un sensor de pistoneo y un modelo de la forma de onda de pistoneo comparándolas entre si para cada ángulo del cigüenaI; cuando hay presente una ?S( 1) mayor que el valor umbral zS(0) (S1 en S202) y el numero de ?S( 1) mayor que el valor umbral ?S(0) es menor o igual que Q(1) (S1 en S300), corregir la forma de onda de la vibracion (S304), calcular (S308) un coefjciente de correlacion K que es un valor relacionado con la desviacion entre la forma de onda de la vibracion corregida y el modelo de la forma de onda de pistoneo; y cuando el numero de ?S( 1) mayor que el valor umbral.?S(0) es mayor que el numero predeterminado Q( 1) (NO en S300), calcular el coeficiente de correlacion K sin corregir la forma de onda de la vibracion. Se determina si hay pistoneo presente o no en base al coeficiente de correlacion K.
