摘　　要：为降低汽车动力总成冷却系统能量能耗,提高整车行驶里程,对某款自主研发的纯电动汽车动力总成冷却系统进行研究,基于动力总成零部件多热源和冷却系统多温区特点,利用一维软件搭建样车动力总成冷却系统计算模型,通过整车实验验证了计算模型的可靠性。在原有基础上提出了MPC控制策略,通过计算分析发现,相比于原有开关阀值控制策略,采用MPC控制策略的动力发热模块温度能更快到达期望温度且温控能力强,同时还降低整个动力总成冷却系统能量的消耗,有利于提升新能源汽车的续航里程。In order to reduce the energy consumption of the automotive powertrain cooling system and increase the mileage of the entire vehicle,a self-developed pure electric vehicle powertrain cooling system was researched based on the characteristics of multiple heat sources of the powertrain components and multiple temperature zones of the cooling system.,A one-dimensional software was used to build a calculation model for the powertrain cooling system of the prototype vehicle,and the reliability of the calculation model was verified through vehicle experiments.A MPC control strategy was proposed based on the analysis.Through calculation and analysis,it was found that the temperature of the power heating module adopting the MPC control strategy could reach the desired temperature faster than the original onoff threshold control strategy.It also reduces the energy consumption of the entire powertrain cooling system,which is conducive to improving the range of new energy vehicles.
