Design and implementation of hybrid electric vehicle motor control system

在对当前国内外混合动力汽车电机控制技术现状进行研究和分析的基础上,提出了一种混合动力电机控制系统。基于数字信号处理器平台完成了一种高性能的混合动力电机控制系统的整体结构设计、核心硬件选型和控制软件设计,搭建了实验平台对方案进行了仿真验证。仿真结果表明,该控制系统在纯电动和混动模式下的各种切换及换挡操作控制中表现良好,且有较快的反应速度,有效提高了混合动力汽车的舒适性和平稳性。

Based on the review of the current situation of hybrid electric vehicle motor control technology at home and abroad, a hybrid electric motor control system is proposed, a high performance hybrid motor control system structure design, core hardware selection and control software design are completed based on digital signal processor (DSP) platform. A simulation platform is built to verify the scheme. The simulation results show that the control system performs well in all kinds of switching and gear shifting control in pure electric and mixed modes, and has a faster response speed. This design improves effectively the comfort and stability of hybrid electric vehicles.
