摘要
为了保证混合动力电动汽车动力性和进一步降低燃油消耗,建立了一个预测控制策略,该控制策略采用齐次马尔科夫链对汽车运行状态特征参数进行预测,并根据预测结果对混合动力电动汽车控制策略中发动机工作范围上下限进行调整。与原电力辅助控制策略相比,建立的预测控制策略降低了运行状态对混合动力电动汽车控制策略的影响,使得车辆能够在不同运行工况中都具有良好的燃油经济性。
In order to decrease the fuel consumption and keep the dynamic of hybrid electric vehicles,a predictive control strategy is proposed in this paper,which can predict the characteristic parameters of driving vehicles by using homogeneous Markov chain,and adjust the maximum and minimum limits of the engine working scope of hybrid electric vehicles according to the predictive result.Comparing to the power auxiliary control strategy,the predictive control strategy can reduce the influence of different driving situations to the control strategy of hybrid electric vehicles,and make the vehicle get a better fuel economy in different driving situations.
