Abstract

Un procedimiento de estimación del estado de la superficie de una carretera que comprende: (a) detectar la vibración de un neumático (10) de un vehículo en circulación; (b) extraer señales de la vibración detectada del neumático; (c) obtener un espectro de frecuencias analizando las frecuencias de las señales extraídas de la vibración del neumático; y a continuación (d) calcular los niveles de vibración en al menos dos bandas de frecuencias predeterminadas a partir del espectro de frecuencias obtenido; y (e) estimar un estado de la superficie de una carretera en base a los niveles de vibración calculados en las al menos dos bandas de frecuencias predeterminadas, en el que en la etapa (b) la vibración de neumático detectada es dividida en una vibración en un dominio pre-final, el dominio existente antes de una posición de borde de final, y una vibración en un dominio post-final, el dominio existente después de una posición de borde de final y, al mismo tiempo, se extraen las señales de la vibración de neumático detectada en el dominio pre-final o las señales de vibración de neumático detectada en un intervalo de tiempo correspondiente al dominio pre-final, y en la etapa (d) las al menos dos bandas de frecuencias están en el dominio pre-final.
