摘要
Abstract
Electrification has emerged as the main trend in new energy vehicles over the past decade.With the increasing number of EVs,reducing their energy consumption aligns with the national strategy for energy conservation and emission reduction,and also improves user's driving experience.The paper first analyzes actual road driving data from an electric SUV.Through dimensional reduction and correlation analysis,the acceleration variance is found as the key factor influencing energy consumption.Furthermore,three typical real-road operating conditions,i.e,constant speed driving,tip in/tip out,and ramp,are chosen for a parametric study by using a 1-D model.The trade-off between energy and time consumption is also discussed.Finally,several principles are established for eco-driving considering the acceleration and speed of vehicles,which include reducing speed during highway cruising,ensuring smooth driving in urban congestion,and utilizing vehicle inertia and minimizing regenerative braking on ramps.关键词
