基于规则的HEV逻辑门限控制策略

混合动力汽车的控制策略对汽车运行时各性能十分重要,也对汽车油耗的高低有着重要的意义。文章以混合动力客车为基础,对其运行中的几种工作模式进行了分析。然后根据汽车的行驶车速下限、实时车速及电池状态,制定了基于规则的逻辑门限控制策略。最后,在CRUISE中搭建了整车模型,并嵌入控制策略完成仿真。结果表明:文章制定的控制策略满足了汽车经济性能,是正确合理的。

Rule Based Logic Threshold Control Strategy for HEV

The control strategy of hybrid electric vehicle is very important not only for the performance of the vehicle,but also for the fuel consumption of the vehicle.Based on the hybrid electric bus,this paper analyzes several working modes in its operation.Then,according to the lower limit of vehicle speed,real-time vehicle speed and battery state,a rule-based logic threshold control strategy is formulated.Finally,the whole vehicle model is built in cruise,and the control strategy is embedded to complete the simulation.The results show that the control strategy developed in this paper meets the vehicle economic performance and is correct and reasonable.
