Abstract

The present invention provides a method of determining a road surface based on vehicle data and by a controller, the method comprising: classifying driving conditions of a vehicle into a plurality of situations; applying a learning logic to each classified situation according to characteristics of the situations, And constructing an inference model for each situation; and based on the inference model for each situation, determining whether the road surface on which the vehicle travels is a high-friction road surface or a low-friction road surface.

Description

[0001] Cross References to Related Applications [0002] This application is based upon and claims the benefit of priority from Korean Patent Application No. 10-2016-0127658 filed with the Korean Intellectual Property Office on October 4, 2016, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The invention relates to a method for determining a road surface based on vehicle data. Background technique [0004] In order to protect the safety of drivers, vehicles have been equipped with various user-friendly systems, such as anti-lock braking system (ABS), electronic stability control (ESC) system, smart cruise control (SCC) system, and advanced driver assistance system (ADAS). [0005] For optimum performance, these user-friendly systems control the vehicle's movements by taking into account road surface conditions. Here, the road surface conditions refer to high-friction road surfaces such as dry asphalt roads and dry ceme...
