Abstract

Un método puede incluir la detección de una primera presión y una segunda presión de un fluido en una tubería de freno de un sistema de vehículos que incluye una pluralidad de vehículos y se extiende desde un vehículo principal hasta un vehículo final. La primera presión puede medirse en el vehículo principal y la segunda presión puede medirse en el vehículo final. El método además puede incluir la determinación de una firma diferencial de presión entre la primera presión y la segunda presión y la evaluación de la firma diferencial de presión con un modelo de aprendizaje automático para determinar si existe una obstrucción o una fuga en la tubería de freno. Un sistema puede incluir uno o más procesadores configurados para detectar una primera presión y una segunda presión de un fluido en una tubería de freno. El uno o más procesadores además puede configurarse para determinar una firma diferencial de presión entre la primera presión y la segunda presión y evaluar la firma diferencial de presión con un modelo de aprendizaje automático para determinar si existe una obstrucción en la tubería de freno.
