摘要/Abstract

摘要：

通过对机电控制无级自动变速器（CVT）结构的分析,提出插电式混合动力车辆搭载机电控制CVT的传动方案。根据传动方案,分析了系统的主要工作模式;根据系统结构,建立了系统动力学模型。在此基础上提出了模式切换过程中基于CVT速比控制的模式切换策略。在MATLAB/Simulink仿真平台上,搭建了系统模式切换控制仿真模型,并进行了纯电动/混合驱动模式切换仿真。仿真结果表明,采用所提出的控制策略与传统切换方式相比,能大大降低系统冲击,提高模式切换品质。研究结果可为机电控制CVT的应用提供理论参考。

Abstract:

Configuration of plug-in hybrid electric system equipped with mechanic-electric CVT was put forward based on the analysis of working principles of mechanic-electric CVT. According to configuration the system working modes were defined and a dynamics mode of hybrid system was built up. Control strategies for mode shifting were put forward, while mode shifting ratios of CVT were controlled according to motor speed. Simulation model was designed and simulation results indicate that the mode shifting quality is improved highly by using control strategies herein.
