Abstract

Un método de estimación de un estado de contacto de un neumático que comprende los pasos de: detectar una vibración del neumático durante la circulación en una parte (23) no suspendida de un vehículo; y estimar el estado de contacto del neumático a partir de la amplitud de un componente de vibración de la banda de frecuencia concreta de la vibración detectada, caracterizado por que se utiliza un neumático (20) para estimación del estado de contacto, incluyendo el neumático un patrón de banda de rodadura que tiene al menos dos tipos de: un bloque (33A, 33B, 33C) definido por una pluralidad de surcos (31) circunferenciales y un surco (32) lateral o un surco (35) de hombro, el cual está conformado en una dirección circunferencial del neumático a ciclo constante, o un bloque simulado (38) que se proyecta desde una parte de campo que continúa en la dirección circunferencial del neumático, hacia la dirección circunferencial del neumático: en el cual las longitudes en la dirección circunferencial del neumático de los al menos dos tipos de bloque o bloque simulado, son diferentes; se detecta una vibración transmitida a la parte (23) no suspendida de un vehículo desde el neumático (20) para estimación de un estado de contacto en la parte (23) no suspendida, la cual aparece cuando el borde posterior del bloque o del bloque simulado abandona una carretera; y se estima el estado de contacto del neumático de acuerdo con la amplitud del componente de vibración en una banda de frecuencia correspondiente con el ciclo de la vibración detectada.

Aplicabilidad Industrial
Como se ha mencionado anteriormente, de acuerdo con la presente invención, dado que el estado de contacto del neumático se puede estimar con precisión sin colocar el sensor sobre el neumático, se puede resolver el problema de la durabilidad del sensor, al mismo tiempo que se puede mejorar la seguridad de circulación del vehículo.
