본 발명은 운전자의 주행 패턴 학습형 스마트 회생 제동방법에 관한 것으로, 주행 데이터를 수집 및 입력하는 단계와, 주행 데이터의 전처리를 통해 감속 데이터를 추출하는 단계와, 감속 데이터에 대한 군집화 및 이상치를 제거하는 단계와, 군집 형성 데이터의 감속도 변화량과 전방 차간 거리를 계산하는 단계와, 다항 회귀(polynomial regression)을 통해 감속도 변화량과 전방 차간 거리의 2차 방정식(quadratic equation)을 도출하는 단계 및, 조건 A 충족 여부를 확인하는 단계를 포함할 수 있고, 또한 상기 조건 A 충족 여부를 확인하는 단계에서, 조건 A 충족하는 경우(YES), 2차 방정식(quadratic equation)을 스마트 회생제동 시스템에 반영하여 제어하는 단계를 수행하고, 조건 A 충족하지 않는 경우(NO), 2차 방정식(quadratic equation)에서 직교 거리를 계산하여 가장 멀리 떨어진 감속 데이터를 제거하는 단계를 수행한다.

    A driving pattern regenerative braking method of a vehicle includes: collecting and inputting driving data, extracting deceleration data through preprocessing the driving data, clustering the deceleration data and removing outliers, calculating a deceleration rate change and an inter-vehicle distance to a vehicle in front from clustered data, deriving a quadratic equation of the deceleration rate change and the distance to the vehicle in front through polynomial regression, determining whether a predetermined condition is satisfied, and if so, modifying a regenerative braking system of the vehicle based on the quadratic equation, all of the above steps being performed by a controller. The method may further include calculating orthogonal distances and removing deceleration data furthest away in orthogonal distance from the quadratic equation if the predetermined condition is not satisfied.
