Abstract
SE DESCRIBE UN METODO PARA DETECTAR UN ESTADO DE FALLO DEL ENCENDIDO MEDIANTE LA INTERPRETACION DE LA ACELERACION DE UN CIGUEÑAL DEL MOTOR (301). EL METODO CONSISTE EN TOMAR UNA MEDIDA DE UNA PRIMERA ACELERACION DEL CIGUEÑAL DEL MOTOR, (405) CERCANA A UN PRIMER ANGULO PREDETERMINADO DEL CIGUEÑAL DEL MOTOR, Y SE HACE UNA PRIMERA LECTURA (407) INDICATIVA DE LA PRIMERA ACELERACION DEL CIGUEÑAL DEL MOTOR, SE MIDE UNA SEGUNDA ACELERACION DEL CIGUEÑAL DEL MOTOR, (417) CERCANA A UN SEGUNDO ANGULO PREDETERMINADO DEL CIGUEÑAL DEL MOTOR, Y SE HACE UNA SEGUNDA LECTURA (419) INDICATIVA DE LA SEGUNDA ACELERACION DEL CIGUEÑAL DEL MOTOR, A CONTINUACION SE COMBINAN (421) LA PRIMERA Y LA SEGUNDA LECTURAS Y SE OBTIENE UN COEFICIENTE DE ACELERACION (423) INDICATIVO DE LAS LECTURAS COMBINADAS. A CONTINUACION, SE INDICA (427) UN FALLO DEL ENCENDIDO CUANDO EL COEFICIENTE DE ACELERACION NO SOBREPASA UN LIMITE PREDETERMINADO.
