摘　　要：电动汽车的总体驱动效率是电动汽车研究的一个重要问题。通过对电动汽车进行整车运动学建模,分析比较了前轮驱动和后轮驱动、单电机和双电机轮边驱动四种情况下的整车驱动效率,提出了一种通过对双电机驱动力矩进行模糊控制的方法,应用该控制方法可以使整车驱动在转向控制时的效率有较大提高。The drive efficiency of the electric vehicle (EV) is a very important subject in the research of the EV. The EV dynamics model including tyre and whole vehicle is founded in this paper. The drive efficiency of the forward-wheel driving and the retral-wheel driving, single-motor driving and double-motor driving is discussed. Then a novel fuzzy control method is developed to control the driving moments of the double motors. The method can increase drive efficiency of EV when turning around.
