为了提高车辆的驱动防滑能力，提出了一种基于滑模极值搜索算法的驱动防滑控制策略。采用滑模极值搜索算法作为一种自寻优方法找到轮胎力一滑转率曲线的极值点，无需估计路面附着系数和建立理想参考模型就可以将轮胎的滑转率控制在最优滑转率附近，提高车辆的动力性和方向稳定性。在Matlab／Simulink中建立车辆系统仿真模型。仿真结果表明，此控制策略能使车辆在驱动过程中快速达到实时路面条件下的最优滑转率，增强了车辆的动力性能。

英文摘要：

In order to improve the vehicle anti-slip performance, an acceleration slip regulation strategy based on extremum seeking control with sliding mode was proposed. Extremum seeking control with sliding mode was used as a self-optimizing way to find the extreme point of tire force-slip rate curve. In this condition, the tire slip ratio near the optimal slip ratio can be controlled without having to estimate the road surface friction coefficient or establishing the ideal reference model to improve the vehicle dynamic performance and directional stability. Moreover, a validated full vehicle simulation model was built in Matlab/Simulink. And the controller based on extremum seeking control with sliding mode was carefully designed. Finally, simulation results showed that during acceleration the vehicle can quickly reach the optimal slip ratio which corresponded to the real-time road conditions with the proposed control strategy. It implied that the proposed control strategy can improve vehicle dynamic performance.
