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 ensure the dynamic of hybrid electric vehicle and further reduce the fuel consumption, a forecast control strategy is established. The control strategy uses the homogeneous Markov chain to predict the characteristic parameters of the vehicle operating status and control the hybrid electric vehicle according to the forecast result Strategy engine operating range upper and lower limits to be adjusted. Compared with the original power-assisted control strategy, the established predictive control strategy reduces the impact of operating conditions on the control strategy of hybrid electric vehicles, making the vehicle have good fuel economy in different operating conditions.
