摘要
为了提高电动汽车机电复合方式完成制动效果,开发了一种能够同时满足能量高效回收并达到安全制动性能的机械摩擦与电机制动相结合的复合制动分配方法。在新标欧洲测试循环工况下和综合行驶工况下,以MATLAB/Simulink、CRUISE进行联合仿真处理的方法完成复合制动力分配策略的评价。通过分配策略模型建立开展仿真测试,同时完成NEDC与综合行驶两种工况下的仿真分析。根据仿真结果可知,本方案再生制动系统运行测试后发现电池SOC降低程度更小,实现对更多制动能量的回收,表现出了优异的节能效果,可以达到现有车辆的制动条件。构建的控制方案获得了比常规控制方案更优的性能,对于各类工况都具备良好的适应性,适合综合行驶工况的行驶要求。
In order to improve the braking effect of electro-mechanical composite braking,a composite braking distribution method combining mechanical friction and motor braking was developed,which could simultaneously meet the requirements of efficient energy recovery and safe braking performance.In the new standard European test cycle and comprehensive driving conditions,the evaluation of the composite braking force distribution strategy was completed by MATLAB/Simulink and CRUISE co-simulation.The simulation test was carried out through the establishment of the allocation strategy model,and the simulation analysis under NEDC and comprehensive driving conditions was completed at the same time.According to the simulation results,after the running test of the regenerative braking system in this scheme,it is found that the battery SOC is reduced to a smaller degree,and more braking energy is recovered,showing excellent energy saving effect,which can meet the braking conditions of existing vehicles.The control scheme constructed in this paper achieves better performance than the conventional control scheme,has good adaptability to all kinds of driving conditions,and is suitable for the driving requirements of comprehensive driving conditions.
