摘要:

基于车辆侧倾运动动力学分析,提出考虑车辆侧倾运动的电动汽车(EV)电子差速控制策略.以自主开发的后轮独立驱动电动汽车为研究对象,在CarSim中建立车辆模型,在Matlab/Simulink中建立电子差速控制模块、滑转率计算观测模块等,进行联合仿真.通过转弯工况仿真测试,验证提出的电子差速控制策略能实现差力和差速功能.在移线工况和横向坡度工况中,与不考虑侧倾运动的电子差速控制策略进行对比仿真试验.仿真结果表明:提出的电子差速控制策略能更好地根据实际工况分配左、右轮驱动转矩,降低车轮的滑转率.通过实车测试进一步验证该策略的有效性.

Abstract:

The electronic differential control strategy considering rolling movement for electric vehicle (EV) was proposed based on the analysis of vehicle rolling movement. A vehicle model was built in CarSim according to the rear wheel independent driving EV, which was developed independently. An electronic differential control module and a slip rate observation and calculation module were built in MATLAB/Simulink. The simulation under turning conditions was done to verify that the proposed electronic differential control strategy could implement differential force and speed functions. The comparing simulation against the electronic differential control without rolling consideration was carried out under the lane change and lateral slope road conditions. The simulation results indicated that the proposed electronic differential control strategy could better distribute driving force to the left and right rear wheels according to the real driving conditions and reduce the slip rate of wheels. The experimental test was done to further verify the effectiveness of the proposed strategy.
