电动汽车运动控制的研究已经取得了很大的进展，但牵引力控制还没有那么复杂和实用，因为车辆的速度和摩擦力是不可测量的。该工作利用驱动电机的特点，估计的最大传输转矩输出在真实的时间的纯运动学关系的基础上，然后提出了一种创新的控制器，直接跟随估计值和约束转矩参考防滑。通过与现有控制方法的比较，所得到的控制设计方法被证明是更有效的和强大的实验电动汽车。此外，一个新的架构的二维车辆稳定性控制系统的基础上提出的牵引力控制。
Research on motion control of electric vehicles has progressed considerably, but traction control has not been so sophisticated and practical because the velocity of vehicles and the friction force are immeasurable. This work takes advantage of the features of driving motors to estimate the maximum transmissible torque output in real time based on a purely kinematic relationship, and then proposes an innovative controller to follow the estimated value directly and constrain the torque reference for slip prevention. By comparison with prior control methods, the resulting control design approach is shown to be more effective and robust on an experimental electric vehicle. In addition, a new architecture for a two-dimensional vehicle stability control system is introduced based on the proposed traction control.
