By a News Reporter-Staff News Editor at Journal of Engineering -- Investigators publish new report on Dynamic Programming. According to news reporting originating in Luoyang, People’s Republic of China, by VerticalNews journalists, research stated, “To achieve best fuel economy control for a parallel hybrid electric vehicle, optimized control based on dynamic programming (DP) is proposed. The main effort in this paper includes the following.”
Financial support for this research came from National Natural Science Foundation of China.
The news reporters obtained a quote from the research from Henan University, “First, the global optimal control mathematic model of the best fuel economy is constructed and its corresponding recursive equation is established. Second, 2 additional augmented cost functions are proposed to prevent frequent gear shifting and frequent engine stopping and starting. Third, an algorithm of restricting the exploring region is proposed to overcome the curse of dimensionality of the numerical DP, which can greatly reduce the computational complexity. Both this DP method and a simple threshold control in corporation of a standby optimization are applied to a vehicle manufactured by the Changan company on the Federal Test Program driving cycle. The results show that the proposed method is effective in reducing fuel consumption by 15%.”
According to the news reporters, the research concluded: “Although the proposed DP method is implemented on a priori known driving cycle, it can provide a criterion to design and evaluate a control strategy to achieve better fuel consumption.”
