This paper presents a novel approach to Direct Yaw-Moment Control (DYC) for four-wheel independent motor-driven electric vehicles, emphasizing the reduction of chattering in Sliding Mode Control (SMC). The proposed methodologies integrate saturation functions and adaptive control strategies, demonstrating significant effectiveness in mitigating chattering while maintaining robust control performance. A comprehensive simulation was conducted using a standard 4WID B-class hatchback model within the CarSim software environment, linked to Matlab/Simulink for execution. Control performance was evaluated using key metrics, including Root Mean Square Error (RMSE) and peak yaw rate, revealing that the proposed methods significantly outperform traditional SMC. Specifically, the incorporation of saturation functions and adaptive control resulted in a marked reduction in chattering, leading to improved yaw rate tracking accuracy and smoother motor torque outputs. Moreover, the findings indicate that these enhancements contribute to the longevity of the motors by minimizing mechanical stress and wear. This study highlights the potential of the proposed control strategies to not only improve the effectiveness of DYC systems but also enhance the reliability and sustainability of electric vehicles in dynamic driving conditions.
