基于路面识别算法的分布式驱动汽车驱动防滑控制策略
Research on acceleration slip regulation strategy based on road surface recognition algorithm
摘要
Abstract
This paper proposes an Acceleration Slip Regulation(ASR)control strategy based on road surface identification algorithm and sliding mode control for distributed drive vehicles on low adhesion coefficient road surfaces,where the ASR control performance is affected by the vehicle mass variation and road slope.Firstly,the vehicle mass and road slope are estimated by recursive least squares method,and the wheel vertical load is corrected.Then,according to the relationship between adhesion coefficient and slip ratio,a road surface identification strategy is designed to obtain the optimal slip ratio as the control target.A sliding mode control algorithm is adopted to achieve fast tracking of the slip ratio.Finally,Carsim and Simulink co-simulation and real vehicle tests are conducted to compare it with the traditional PI control strategy.Our simulation results show the proposed strategy reduces the RMSE value of slip ratio error by 75.1%,but the real vehicle RMSE is larger.The vehicle test demonstrates the control algorithm proposed in this paper performs better in vehicle slip rate control.关键词
