摘要 论述了分布式驱动电动汽车性能,并以试制的样车为研究对象,在四轮转鼓试验台上进行了行驶特性试验,表明了其百公里加速时间为12 s以内、最高车速在150 km/h以上的优越性。为提高整车能量利用率及延长续驶里程,提出了行驶能耗优化方法,并通过仿真对比分析了多种转矩分配策略下的行驶能耗。结果表明,所提出的优化方法可减少3.41%的能耗,从而提高了整车行驶效率,延长了行驶里程。 Performance of distributed driving electric vehicle is discussed in the paper, and driving characteristic test is performed to a prototype as research object on four-wheel drum dynamometer, which demonstrates less than 12seconds of 0~100 km acceleration, maximum vehicle speed of over 150 km/h of the electric vehicle. To improve vehicle energy utilization rate and extend driving range, driving energy optimization method is put forward, which is analyzed under multiple torque distribution strategies by simulation and comparison. The results show that the proposed optimization can reduce energy consumption of 3.41 %, thus improve vehicle driving efficiency and extend driving range.
