Application of dynamic programming algorithm in study of energy management strategy for single-shaft parallel hybrid electric vehicle

Programming (DP) as a control strategy optimization algorithm, is very suitable for the development of energy management strategy for hybrid electric vehicle, which is under the certain typical Chinese urban condition in this paper. Using the results of optimal fuel economy, emissions and non-frequent shifting to extract realizable energy management strategy and shifting strategy, which is simulated in the co-simulation platform Cruise/Simulation. The simulation results are compared to the results of logic rules-based energy management strategy and shifting strategy, which show that, the energy management strategy and shifting strategy based on DP takes full advantages of single-shaft parallel hybrid electric vehicle, and means a big guiding significance for the energy management strategy development and shifting strategy.
