Intelligent Weighted Hierarchical Direct Yaw Moment Control for Distributed Drive Electric Vehicles

Strategic Insights

— 1 min read

Researchers at East China Jiaotong University have developed a novel control method for distributed drive electric vehicles (DDEVs) equipped with four-wheel independent drive (4WID) systems. The study aimed to address the challenge of dynamic coupling between yaw rate and sideslip angle in Direct Yaw Moment Control (DYC) systems. The proposed method, Fast Adaptive Super-Twisting Sliding Mode Control (FASTSMC), utilizes a hierarchical control architecture to achieve structural flexibility and modularity. The research demonstrated the effectiveness of the proposed method in reducing sideslip angle by 54.7% under step input conditions and decreasing yaw rate by 22.4% during double-lane change conditions.

Key Takeaways:

  • The proposed FASTSMC strategy offers advantages in structural flexibility and modularity for DYC systems.
  • The method utilizes a hierarchical control architecture to address dynamic coupling issues.
  • The study demonstrates the effectiveness of FASTSMC in reducing sideslip angle and yaw rate under various driving conditions.
  • The method integrates a data-driven neural network with online updating based on phase plane stability parameters to improve adaptability.
  • The proposed approach dynamically adjusts weight coefficients in real-time according to phase plane theory, ensuring stable yaw moment control.
  • The research was funded by The Key R & D Program of Jiangxi Province, The Open Bidding For Selecting The Best Candidates Program of Nanchang, and others.
  • The study includes contributions from researchers at East China Jiaotong University, including Yuanhao Cai, Yiming Hu, Dequan Zeng, Jinwen Yang, Xiaoliang Wang, Qin Yu, Weidong Liu, and Zhiqiang Jiang.
