基于SWIFT轮胎模型的防抱死制动系统控制算法仿真

The Simulation of Anti-Lock Brake System Control Algorithm Based On SWIFT Tire model

在汽车防抱死制动系统(ABS)开发过程中,需要通过大量的实车试验完成参数标定以保证产品性能和鲁棒性。对于缩短开发周期而言,在设计阶段基于模型实现ABS控制算法的标定和迭代优化具有重要价值。本文建立了包含平面内SWIFT轮胎模型在内的四分之一车辆模型,建立了防抱死制动系统模型并设计了基于规则的逻辑门限ABS控制算法,并基于该平台验证了ABS控制算法的合理性。

Recently,Much vehicle test is needed to improve the performance and robustness of ABS during the development,The ABS calibration and the algorithm improvement based on the model will reduce the development time.In this paper,the SWIFT tire and ABS model is built up,and the ABS control algorithm is designed.Finally,the performance and robustness of ABS control algorithm is proved based on the model.
