48 V ISG微混动力系统车辆整车控制策略研究

Research on Vehicle Control Strategy of 48 V ISG Micro Hybrid Power System

以某款传统汽车为原型车,在原车12 V电气系统的基础上,设计一种48 V微混动力系统。基于Cruise软件建立整车模型,通过与控制策略模型的联合进行动力性、经济性仿真,并与原型车的仿真结果进行比较分析。结果表明:该车在实现功率辅助的基础上降低了油耗和排放。

In this paper,a 48 V mild hybrid power system is designed based on the original 12V electric system.The vehicle model based on Cruise software is used to simulate the dynamic and economic performance by combining with the control strategy model,and the simulation results of the prototype vehicle are compared and analyzed.The results show that the fuel consumption and emission are reduced on the basis of power assistance.
