Abstract

Una unidad de control electronico (ECU) de motor incluye un filtro pasabanda (1) que extrae solamente vibraciones a una primera banda de frecuencia A, un filtro pasabanda (2) que extrae solamente vibraciones a una tercera banda de frecuencia C y un filtro pasabanda (4) que extrae solamente vibraciones a una cuarta banda de frecuencia D, que incluye la primera a tercera banda de frecuencia A-C. La ECU del motor determina si ocurrio o no la detonacion (knocking) basándose en una forma de onda de vibracion de la cuarta banda de frecuencia D y un valor pico en magnitud de vibraciones en una forma de onda sintetizada de la primera a tercera banda de frecuencia.
