摘　　要：本文主要分析电动汽车在不同运行规律下的耗能大小,从而求出耗能最小的运行规律。其方法是:先运用拉格朗日乘子法对状态空间方程进行变分,推出目标泛函取得极值的必要条件,再通过Matlab进行求解,最后给出最优解。通过对比最优运行规律与其他几种运行规律的耗能情况,验证了最优运行规律下电动汽车的耗能最小。This paper mainly analyzes the energy consumption of electric vehicles under different operation laws,and obtain a operation law with the minimum energy consumption.The method is as follows:firstly,the Lagrange multiplier method is used to variational the state space equation,and the necessary conditions for obtaining the extreme value of the objective functional are derived.Then it is solved by matlab,and finally the optimal solution is given.By comparing the energy consumption between the optimal operation law and other operation laws,it is verified that the energy consumption of electric vehicle under the optimal operation law is the lowest.
