[Abstract]:In order to improve fuel economy, the optimal energy distribution control strategy of parallel hybrid vehicle is established. The dynamic programming algorithm is improved in order to optimize the output power of internal combustion engine and battery in order to improve the energy efficiency. The simulation results of the simulation software ADVISOR2002 show that under the same conditions, the simulation time is greatly shortened when the improved DP algorithm is used to optimize the energy of the parallel hybrid electric vehicle. Compared with the fuel consumption based on switching energy optimization management strategy, the fuel consumption of the energy optimization management system based on the improved DP algorithm can be reduced by 33%.
