Abstract

LA DESCRIPCION SE REFIERE A UN DISPOSITIVO PARA RECONOCIMIENTO DE FALLO EN CONEXION CON UN DISPOSITIVO DE DETECCION DE PICADO EN UN MOTOR DE COMBUSTION INTERNA. LA SEÑAL DE SALIDA DEL SENSOR SE COMPARA CON UN NIVEL DE REFERENCIA STANDARD DEPENDIENDO DE LA VELOCIDAD DE ROTACION PARA LA DETECCION DEL PICADO DE MOTOR. DEPENDIENDO DEL RESULTADO DE COMPARACION SE DETECTA EL PICADO Y, CUANDO ESTE EXISTE, SE INICIAN ETAPAS PARA PREVENIR EL PICADO. PARA PREVENIR QUE EL MOTOR DE COMBUSTION INTERNA FUNCIONE DE FORMA INAPROPIADA EN CONDICIONES DE OPERACION INACEPTABLES EN EL CASO DE FALLO DE UN SENSOR DE PICADO O DE SU CIRCUITO DE EVALUACION, SE DISPONE DE UN PROCESO DE DETECCION DE ERROR CONTINUO QUE CHEQUEA SI EL NIVEL DE REFERENCIA STANDARD SE ENCUENTRA DENTRO DE UN CAMPO PERMISIBLE DEPENDIENDO DE LA VELOCIDAD DE ROTACION, MIENTRAS QUE ESTE CAMPO ES O BIEN LA BANDA DE NIVEL DE REFERENCIA STANDARD PERMISIBLE O UN CAMPO ENTRE UN LIMITE (UGO) SUPERIOR Y UN LIMITE (UGU) INFERIOR, DEPENDIENDO AMBOS DE LA VELOCIDAD DE ROTACION. SI EL NIVEL DE LA SEÑAL DE REFERENCIA STANDARD ABANDONA ESTE CAMPO DURANTE UN TIEMPO PREDETERMINABLE, SE DETECTA UN FALLO Y SE INICIAN MEDIDAS DE SEGURIDAD QUE PERMANECE OPERATIVO HASTA QUE EL NIVEL DE REFERENCIA SE ENCUENTRA DE NUEVO DENTRO DEL CAMPO PERMISIBLE.
