摘要： 直接横摆力矩控制（DYC）可增强车辆二维运动的稳定性。该文建立了一个两轮的车辆模型作为控制参考模型，以便提高对电动汽车轮毂电机的二维运动控制的稳定性和实用性。基于最大可传递转矩估计（MTTE）的牵引力控制，可用于抑制打滑现象以增强纵向和横向摩擦力，并可提供关于轮胎与路面间的额外信息。提出了一种新的基于MTTE的DYC策略。经过完整控制系统的MTTE增强型DYC与常规DYC的数值仿真对比，结果验证了这种控制策略的优越性。

Abstract: The Direct Yaw Moment Control (DYC) is an effective way to enhance the two-dimensional motion stability of vehicles. A two-wheel vehicle model as a reference model was built to improve the performance and the practicality of two-dimensional motion control for electric vehicle in-wheel motors. The traction control was based on Maximum Transmissible Torque Estimation (MTTE) for constraining the slip effectively to increase the longitudinal friction force and lateral friction force, but also could provide some additional information on tire-road conditions. A new DYC topology was proposed based on MTTE for electric vehicles. The comparative numerical simulation of the whole control system between the normal DYC and the DYC enhanced by MTTE demonstrated the advantages of the proposed control strategy.
