从动轮滑转率影响汽车的行驶稳定性，而从动轮滑转率可以通过从动轮扭矩来控制。在由内燃机提供动力的车辆中，扭矩可以由发动机管理系统控制。滑模算法是牵引力控制系统（TCS）设计背后的机制。纵向滑移由节流阀的位置控制。所使用的车辆模型具有七个自由度和两状态发动机模型，即，进气歧管中的空气质量和发动机转速。时间延迟运输被认为是在发动机模型中使用。轮胎受力计算采用非线性组合滑移模型。针对轮胎、车辆和发动机的非线性动态特性，采用滑模变结构控制方法，具有较强的鲁棒性。基于动态曲面控制设计了控制器，定义了两个一阶曲面。仿真结果表明，该控制器的有效性与不同的机动。结果表明，在不同的道路条件下，装有TCS的车辆的加速性能，方向稳定性和转向性能得到改善。原因是通过将滑差保持在期望的范围内来控制滑差。
The driving stability is affected by driven wheel slip, which can be controlled by the driven wheel torque. In a vehicle powered by an internal combustion engine, the torque can be controlled by an engine management system. The sliding mode algorithm is the mechanism behind the design of the traction control system (TCS). The longitudinal slip is controlled by the position of the throttle valve. The vehicle model used has seven degrees of freedom and a two-state engine model, i.e., the mass of air in the intake manifold and the engine speed. Time-delay transport is considered in the engine model used. A nonlinear tire model for combined slip is used for tire force computation. Due to the nonlinear dynamic of the tire, vehicle, and engine, the control method of sliding mode is used for its robustness. A controller is designed based on the dynamic surface control, for which two first-order surfaces are defined. The effectiveness of the controller is demonstrated with simulation results for different maneuvers. Results show that for different road conditions, the acceleration performance, directional stability, and steerability of a vehicle equipped with TCS is improved. The reason is that the slip is controlled by keeping it in a desired range.
