摘要: 为解决分布式电驱动客车在低附着路面上起步时驱动轮易发生过度打滑的问题,提出一种基于路面识别和自适应滑模控制(ASMC)的驱动防滑(ASR)控制策略。建立非线性的车辆动力学模型和Dugoff轮胎模型,基于奇异值分解的高阶容积卡尔曼滤波算法设计了路面附着系数估计方法;结合目标车型的轮胎参数,利用TruckSim中的轮胎测试模块对轮胎特性进行测试,确定不同路面下的最佳滑转率,并基于此设计了ASR触发与退出机制;设计了基于ASMC的防滑控制算法,其趋近律中引入了指数自适应增益,能够依据误差大小自适应调整控制力度,加快滑转率跟踪速度并抑制超调;结合采集到的实车起步工况数据设置测试工况,基于MATLAB/Simulink与TruckSim的联合仿真平台,在不同起步工况和载重下对所提出的ASR控制策略的性能进行验证,并与传统模型预测控制(MPC)、一阶滑模控制(FOSMC)和积分滑模控制(ISMC)方法进行了对比。分析结果表明:在4种典型测试工况下,基于ASMC的ASR控制策略使滑转率跟踪的平均绝对误差和均方根误差均为最小值;使客车车速比MPC分别提升30.45%、10.01%、24.55%和13.45%,比FOSMC分别提升5.62%、5.08%、5.38%和6.35%,比ISMC分别提升4.09%、2.74%、3.21%和4.64%。所提出的ASR控制策略能够提升分布式电驱动客车的纵向稳定性和驱动性能,对分布式电驱动客车的扭矩控制系统设计具有重要参考价值。Abstract: To solve the problem of excessive slippage of the driving wheels when distributed electric drive buses start on low-adhesion roads, an acceleration slip regulation (ASR) control strategy based on road identification and adaptive sliding mode control (ASMC) was proposed. A nonlinear vehicle dynamics model and a Dugoff tire model were established. A road adhesion coefficient estimation method was designed based on the high-degree cubature Kalman filter algorithm with singular value decomposition. Combined with the tire parameters of the target vehicle model, the tire test module in TruckSim was utilized to test tire characteristics and determine the optimal slip ratios under different road surfaces, based on which an ASR trigger and exit mechanism was designed. An anti-slip control algorithm based on ASMC was designed, into the reaching law of which an exponential adaptive gain was introduced to adaptively adjust the control force according to the error size, accelerate the slip ratio tracking speed, and suppress overshoot. Test maneuvers were set combined with the collected real-vehicle starting data. Based on the joint simulation platform of MATLAB/Simulink and TruckSim, the performance of the proposed ASR control strategy was verified under different starting maneuvers and loads and compared with the traditional model predictive control (MPC), first-order sliding mode control (FOSMC), and integral sliding mode control (ISMC) methods. Analysis results indicate that under four typical test maneuvers, the ASR control strategy based on ASMC minimizes both the average absolute error and root mean square error of slip ratio tracking; it increases the bus speed by 30.45%, 10.01%, 24.55%, and 13.45% compared with MPC, by 5.62%, 5.08%, 5.38%, and 6.35% compared with FOSMC, and by 4.09%, 2.74%, 3.21%, and 4.64% compared with ISMC, respectively. The proposed ASR control strategy can improve the longitudinal stability and driving performance of distributed electric drive buses, providing an important reference for the torque control system design of distributed electric drive buses.
