Abstract

Un controlador para un vehículo autónomo recibe señales de audio de uno o más micrófonos. Las señales de audio se ingresan a un modelo de aprendizaje automático que clasifica la fuente de las características del audio. Por ejemplo, las características pueden clasificarse como que se originan en un vehículo. Una dirección a una fuente de las características del audio está determinada a partir de los retrasos relativos de las características del audio en las señales de múltiples micrófonos. Donde las características del audio se clasifican con una confianza por sobre el umbral como que se originan en un vehículo, la evitación de colisiones se realiza con respecto a la dirección a la fuente de las características del audio. La dirección a la fuente de las características del audio puede correlacionarse con las imágenes del vehículo y/o los datos de mapa para aumentar una calificación de confianza de que la fuente de las características del audio es un vehículo estacionado con el motor en funcionamiento. La evitación de colisiones puede, entonces, realizarse con trayectorias potenciales del vehículo estacionado.
