백스테핑 기반 차선 유지 시스템

Abstract

In this paper, we propose backstepping based lane keeping system (LKS). In general, the dynamics considering the error with respect to road do not include look-ahead distance. To make use of the look-ahead distance, we reformulate the lateral dynamics of the vehicle as normal backstepping form. As a result, the state used in the lateral dynamics is change into the new state which considers look-ahead distance of the vehicle. The proposed method was validated via simulations which consists of MALAB/Simulink and CarSim.
