Abstract: A new energy optimization strategy for Toyota PRIUS hybrid electric vehicle is proposed based on the linear optimal control theory. In this strategy a quadratic performance index is built combined with several rules to restrict frequent and large-scale fluctuation on engine output power, thus, realizing direct reduction of fuel consumption while still maintaining the vehicle good driving performance. Based on the second development of ADVISOR software, the vehicle simulation model is established to verify the effectiveness of the proposed strategy. Simulation results show that the energy optimization strategy has better oil-saving effect than the rule-based energy management strategy over different driving cycles.

Key words: vehicle engineering, hybrid electric vehicle(HEV), energy management strategy, quadratic optimal control
