The present invention relates to a method for determining a road surface based on vehicle data. After a driving situation of a vehicle is classified into a predetermined case, a learning logic matching to a feature of each case is applied to compose an inference model by case. Based on the inference model by case, a road surface on which the vehicle is traveling is determined to be a high-friction road surface or a low-friction road surface such that a state of a road surface can be quickly and precisely determined regardless of a shape of a road. To this end, the method for determining a road surface based on vehicle data of the present invention comprises: a step of classifying the driving situation of the vehicle into a plurality of cases; a step of composing the inference model by case by applying a learning logic matching to the feature of each of the classified cases; and a step of determining whether the road surface on which the vehicle is traveling is a high-friction road surface or a low-friction road surface based on the inference model by case.

    본 발명은 차량 데이터 기반의 노면 판단 방법에 관한 것으로, 차량의 주행상황을 소정의 케이스로 분류한 후 각 케이스의 특성에 맞는 학습 로직을 적용하여 케이스별 추론모델을 구성하고, 상기 케이스별 추론모델을 기반으로 차량이 주행중인 노면이 고마찰 노면인지 저마찰 노면인지 판단함으로써, 도로의 형태에 상관없이 신속 정확하게 노면의 상태를 판단할 수 있는 차량 데이터 기반의 노면 판단 방법을 제공하고자 한다. 이를 위하여, 본 발명은 제어기가 차량 데이터를 기반으로 노면을 판단하는 방법에 있어서, 차량의 주행상황을 복수의 케이스로 분류하는 단계; 상기 분류된 각 케이스의 특성에 맞는 학습로직을 적용하여 케이스별 추론모델을 구성하는 단계; 및 상기 구성된 케이스별 추론모델을 기반으로 차량이 주행중인 노면이 고마찰 노면인지 저마찰 노면인지 판단하는 단계를 포함한다.
