插电式混合动力四轮驱动SUV控制策略研究

On the Control Strategy of Plug-in Hybrid Four-wheel Drive SUV

基于无级变速可插电混合动力四轮驱动SUV系统,对其运行模式及控制策略进行研究分析,并基于MATLAB/SIMULIk/stateflow建立了整车的控制策略模型,利用Mototron快速原型开发工具对其策略进行实车验证,结果表明:该控制策略下,整车模式切换平顺,混合动力模式下城市工况下节油超过25%。

Based on the continuously variable speed system on the plug-in hybrid four-wheel drive SUV, its operating mode and control strategy are studied and analyzed. Its control strategy model of the vehicle is set up based on MATLAB/SIMULIk/stateflow and verified on real car by the rapid prototyping tools Mototron. The results show that the vehicle mode can switch smoothly and it saves fuel more than 25% under hybrid mode and urban conditions.
