摘要：能源危机和环境污染这两大问题日益突出，传统内燃机汽车由于生产制造和运行过程中能源消耗较大，已不能适应人类可持续发展战略思想。因此开展新型动力汽车已刻不容缓。混合动力电动汽车(HEV)凭借其高效、节能、低污染的优势脱颖而出，成为了传统汽车向纯电动汽车的完美过渡，在提高功能效率和降低污染等方面有很好的应用前景。 混合动力驱动系统控制策略研究是混合动力汽车开发的核心技术之一，对混合动力驱动系统的控制策略研究具有现实意义。以燃油经济性和延长电池寿命为指标，设计以转矩差值△T和动力电池SOC为输入变量、转矩系数K为输出变量的模糊控制器，并在Matlab /Simulink环境下设计模糊控制器后，将其嵌入ADVISOR中。在道路循环CYC_UDDS和CYC_LOCAL分别调用添加的模糊控制策略，并与ADVISOR内置模糊控制策略对比仿真，结果表明设计的模糊控制策略在降低油耗和延长电池寿命方面具有一定的优越性。32474

The Design of the Driving Control of Hybrid Electric Vehicle
Abstract ：Energy crisis and environmental pollution become increasingly prominent，The manufacturing process and operation of traditional engine car consume so much energy that it can’t meet the requirements of sustainable development. Therefore, the new power car to carry out research has been pressing. Hybrid electric vehicle (HEV) comes to the fore depending advantages that’s high efficiency, energy saving，low pollution, which has become perfect transition from conventional vehicles to electric vehicles. HEV has a very good application prospect in improving economic performance and reduced emissions, etc. How to design a suitable control strategy of hybrid drive system is one of the core technologies in hybrid electric vehicle. So it is realistically significant to research on control strategy for hybrid drive system. Aiming at improving the fuel economy and extending the battery life, The proposed fuzzy logic controller built in Matlab/Simulink has two input variables: torque difference △T and SOC of battery and one output variable: torque coefficient. The designed fuzzy control strategy is called in the CYC_UDDS and CYC_LOCAL cycle separately and validated by ADVISOR. And the obtained results are also compared with the one obtained via the built-in fuzzy control strategy. The comparison results show that oil consumption is reduced and battery life is extended by using the designed fuzzy logic control strategy.
