Method and apparatus for estimation of tire-road type by using ultrasonic signal

摘要

The present invention relates to a method and apparatus for estimating a road surface type using an ultrasonic signal, and to a method for estimating the type of a road surface using a machine-learned artificial neural network model for the reflected ultrasonic signal, and an apparatus for performing the same. will be. According to the present invention, a method and apparatus for providing highly accurate road surface information at low cost by establishing a model between the two by machine learning the characteristics of the ultrasonic signal reflected from the road surface and the road surface condition, and estimating the type of the road surface using the same. Provides. In particular, there is an effect of contributing to safer driving by accurately estimating even the black ice on which the conventional road surface friction coefficient could not be grasped.
