초록

Regenerative braking is essential for improving energy efficiency in electric vehicles, yet control strategies for coasting remain underdeveloped. Existing control methods respond conservatively to wheel slip, limiting regenerative torque usage and degrading deceleration consistency and lateral stability. This study proposes an advanced regenerative braking control algorithm that maintains longitudinal slip stability, enhances yaw stability, and better preserves the driver's intended regenerative braking. The controller integrates a slip controller, a yaw stability controller, and a torque compensator, which are coordinated based on real-time slip conditions. Simulation and vehicle experiments verify the proposed method, confirming an average 64% improvement in preserving driver braking intention and a 37% reduction in yaw rate MAE, thereby demonstrating its effectiveness and practical applicability to production EVs.
