Variable Parameter Self-Adaptive Control Strategy Based on Driving Condition Identification for Plug-In Hybrid Electric Bus

doi:10.15918/j.jbit1004-0579.17156
  • Received Date:2017-11-09
  • A variable parameter self-adaptive control strategy based on driving condition identification is proposed to take full advantage of the fuel saving potential of the plug-in hybrid electric bus (PHEB). Firstly, the principal component analysis (PCA) and the fuzzy c-means clustering(FCM)algorithm is used to construct the comprehensive driving cycle, congestion driving cycle, urban driving cycle and suburban driving cycle of Chinese urban buses.Secondly, an improved particle swarm optimization (IPSO) algorithm is proposed, and is used to optimize the control parameters of PHEB under different driving cycles, respectively. Then, the variable parameter self-adaptive control strategy based on driving condition identification is given.Finally, for an actual running vehicle, the driving condition is identified by relevance vector machine (RVM), and the corresponding control parameters are selected to control the vehicle. The simulation results show that the fuel consumption of using the variable parameter self-adaptive control strategy is reduced by 4.2% compared with that of the fixed parameter control strategy, and the feasibility of the variable parameter self-adaptive control strategy is verified.
