摘要
基于加速能力、爬坡能力、最高车速和变速器挡位数、驱动电机参数之间的耦合关系分析,开展增程式电动汽车驱动系统关键动力部件的参数匹配及选型确定。采用Matlab/simulink建立增程式电动汽车整车仿真模型,对纯电动模式下的动力性和经济性进行仿真验证,动力性表现为0~50km/h加速时间为4.24秒,50~80km/h超车加速时间为7.16秒,纯电动状态下行驶里程约为83.86km,车辆百公里能耗约为14.516kwh,表明所确定的关键动力部件满足动力性及经济性的匹配要求。
Based on analysis of coupling relationship among acceleration ability,climbing ability,maximumspeed,transmission gears and driving motor parameters,key power components parameters matching and selectionof Extended-range Electric Vehicles(e-revs)drive system is carried out.Finally e-revs vehicle simulationmodel is established with Matlab/simulink to simulate and verify the dynamic and economy performance underelectric mode.The dynamic performance of the0-50km/h acceleration time was4.24seconds,overtaking50-80km/h acceleration time is7.16seconds,pure electric mode mileage is about83.86km,the vehicle energyconsumption per hundred kilometers is about14.516kwh.The results show that key power components meet thedynamic performance and economy matching requirement.
