Driving pattern regenerative braking method of vehicle

Abstract

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.
