摘　　要：为了不改动传统制动系统而使电动汽车具有良好的制动能量回收能力,文章提出基于路面识别的并联式制动能量回收策略。通过对电动汽车驱动时的特性分析,提出典型路面的识别方法,设计了各种典型路面状况下的电制动力分配策略,在Matlab/Simulink中搭建了相应的仿真模型,仿真验证了策略的可行性,在该策略下,电动汽车拥有良好的制动能量回收率。In order to make electric vehicle have good brake energy regeneration ability without chan- ging the traditional braking system, a parallel brake energy regeneration strategy based on road recognition is proposed. By analyzing the driving characteristic of electric vehicle, a method of typical road recognition is proposed, and the electric braking force distribution strategies under various typical road conditions are designed. The corresponding simulation model is built in Matlab/Simulink based on the distribution strategies, the simulation results verify the feasibility of the strategies, and the electric vehicle has good brake energy regeneration rate by applying the strategies.
