摘要
利用Simuink软件构建了混合动力汽车制动系统再生效率数学模型,在Simuink环境下就不同关键参数对于再生效率的影响进行了仿真实验。仿真结果显示:汽车外部阻力消耗的能量比例最大,变速机构次之,通过排量控制曲线优化混合动力汽车变量泵/马达工作区间,可以有效提高液压混合动力系统能量再生效率,有积极的应用前景。
Use Simuink software constructs the hybrid cars braking system regeneration efficiency mathematical model, in Simuink environment is different key parameters on the efficiency of the regeneration effect on the simulation results, the simulation results show that： the automobile external resistance energy consumption proportion is the largest, variable speed mechanism is the second smallest, and through the displacement control curve optimization hybrid cars variable pump/motor work interval, can effectively improve the hydraulic hybrid system energy regeneration efficiency, have a positive application prospect.
