基于能量效率的HEV多模式控制策略及判据研究
|
摘要
以某款混联式HEV为研究对象,建立了车辆动力系统仿真模型及整车能量控制策略优化模型。对比不同需求驱动转矩下的整车能量转换效率发现,在电池剩余电量及车速相同条件下,随着驾驶人需求驱动转矩的增加,HEV能量转换效率呈现"凸抛物线"规律。基于该规律,形成了HEV能量控制策略动力性、平衡性和经济性控制规则的划分判据。
Simulation model of vehicle driving system and energy control strategy optimization model have been built with a series-parallel HEV as research object. Vehicle energy conversion efficiency under different demanded driving torques was compared, which indicated that HEV energy conversion efficiency showed a "U" parabola rule with the increase of demand torque, under the same battery remaining capacity and vehicle speeds. Based on this rule, the division criteria of control rule for HEV energy strategy dynamic property, balance and economy was formed.
