摘　　要：综合考虑发动机、发电机和电动机效率,提出了混联式混合动力电动汽车动力系统能量控制策略的瞬时优化方法。运用ADVISOR软件建立了混联式混合动力电动汽车动力系统能量控制策略瞬时优化控制器。在行驶工况条件下,对发动机、电动机和发电机功率进行了基于能量利用率的瞬时优化仿真分配。仿真结果表明,与ADVISOR的控制策略相比,能按行驶工况有效地调节混合动力电动汽车各动力的分配,使之具有较高能量利用率。Considering the efficiency of the engine,electric motor and generator comprehensively, instantaneous optimization method of energy management control strategy of parallel- serial hy- brid electric vehicles is proposed. In order to optimize the power distribution among engine, electric motor and generator based on energy usage rate under the driving conditions, the controller of in- stantaneous optimal control strategy is established. Comparing with the control strategy of the original model in ADVISOR, this method can effectively adjust the power distribution of the hybrid electric vehicle and improve energy usage rate.
