The invention provides an economical type transverse stability control method for a distributed-drive electric vehicle, and belongs to the technical field of vehicle control. The transverse stabilitycontrol method constitutes a kinetic model of an AFS and DYC integrated system containing economy coordination factors I, optimizes a proportion between an additional yawing moment and the AFS system,and improves work efficiency of a hub motor, thus improving economical indexes of the distributed-drive electric vehicle. The method further designs a self-trigger type model predicating control scheme based on an AMHE and NEA mode switching strategy, reduces influences, on AFS and DYC integrated control effect, by disturbance, and improves accuracy of vehicle lateral stability control on the premise of guaranteeing real-time property of the control system.

    本发明提供了一种分布式驱动电动汽车的经济型横向稳定性控制方法,属于车辆控制技术领域。本发明横向稳定性控制方法构造了含有经济协调因子l的AFS和DYC集成系统的动力学模型,优化附加横摆力矩和AFS系统之间的配比,提高轮毂电机的工作效率,进而提升分布式驱动电动汽车的经济性指标;本发明方法还设计了基于AMHE和NEA模式切换策略的自触发式模型预测控制方案,降低扰动对AFS和DYC集成控制效果的影响,在保证控制系统实时性的前提下,改善车辆侧向稳定性控制的准确性。
