摘  要：
为了充分利用四轮独立驱动(4WD)与直接横摆力矩控制(DYC)各自的优势,提出了基于全轮纵向力优化分配的4WD车辆DYC系统方案。利用改进的2DOF车辆模型制定DYC稳定性控制目标,设计基于最优动态滑模的"前馈+反馈"DYC控制器。建立全轮纵向力优化分配模式,结合HSRI轮胎模型设计了降低整车路面附着负荷的目标函数,并通过约束优化得出全轮纵向力分配值。研究表明,全轮纵向力优化分配可提高整车路面附着余量,进一步提升了DYC系统的控制性能。

摘  要：
A new 4WD vehicle DYC system based on the tire longitudinal forces optimization distribution was proposed to combine the advantages of DYC and the independent four-wheel-drive chassis.The modified 2DOF vehicle model was utilized to obtain the DYC target for vehicle stability.The "feedforward + feedback" DYC controller was designed with the optimal dynamical sliding mode.The tire longitudinal forces optimization distribution mode was established with the stability index combining HSRI tire model to increase the vehicle-road grip margin.The index was constraining calculated to obtain tire forces distribution results.The simulation result shows that the remaining part of the vehicle-road adhesion is increased by the optimization distribution under DYC,which means the vehicle stability potential is improved than using the general distribution method,i.e.DYC is enhanced further.
