摘要
基于多领域统一建模语言Modelica建立了电动汽车整车模型及真空助力制动系统模型,提出了基于车辆数据采集系统VBOX-3i的测试方法,并通过对电动中巴车的实车路况测试验证了仿真模型的准确性。在此基础上,利用正交试验法对真空助力制动系统参数进行了优化匹配。采用优化匹配参数后,降低了约14.2%的真空制动系统能耗。
A simulation model of electric vehicle and vacuum assist brake system based on multi-domain unified modeling language-Modelica is established. A testing method based on VBOX-3i data logger is proposed. The simulation results agree with the test results and the accuracy of the model is verified. Based on the model, the parameters of vacuum assist brake system are optimized by orthogonal experiment method. The optimized parameters can reduce energy consumption of the vacuum assist brake system by approx. 14.2%.
