摘要
通过分析双桥独立电驱动车辆寄生功率的产生原因,推导出了寄生功率的判别公式,以及寄生功率流向的判断,进一步提出了寄生功率的计算公式,结合双桥独立电驱动车辆的整车参数,利用MATLAB仿真软件对其进行了仿真,分别以路面附着情况和驱动电动机恒功率输出为依据,得出在电动机恒功率工作时,寄生功率会随着路面附着性能的改善增大,随着行驶阻力的增加而减小的结论。
According to the produce causing analysis of reactive power in electric vehicle driven by two independent motors, the distinguish formula and flow of reactive power were educed, and the calculation formula of reactive power was advanced. With the simulation of electric vehicle parameters using MATLAB, the influence factors of reactive power were obtained under road adhesion conditions and motor constant output, which was reactive power would aggrandize along with road adhesion performance improving and steaming resistance minish under the motor constant work.
