混合动力电动汽车转矩管理控制策略设计

混合动力汽车的出现在一定程度上缓解了能源危机和环境问题。控制策略作为混合动力汽车的核心技术，对动力性和燃油经济性的实现起到至关重要的作用。主要研究模糊逻辑控制策略的制定及基于 Advisor 的仿真。提出了将总需求转矩和电池荷电状态划分为更多模糊子集以得到更细的模糊规则的方法。通过比较仿真结果验证了细分的模糊逻辑控制策略对提高动力性和燃油经济性的积极作用。

Designing of Torque Control Strategy for Hybrid Electric Vehicle

The emergence of hybrid vehicles,to a certain extent,ease the energy crisis and environmental problems. As the core technology of hybrid vehicles,control strategy plays a crucial role for the realization of the power performance and fuel e-conomy. The main content of the article is the fuzzy logic control strategy design and stimulations based on Advisor,presents that dividing the aggregate torque demand and the battery charged state into more fuzzy subset to pour more fine method of fuzz-y rules. The stimulant results verify the subdivision of the fuzzy logic control strategy is positive to improve power performance and fuel economy.
