本发明公开了一种坡道预测自适应ECMS混合动力汽车能量管理方法,本发明涉及混合动力汽车技术领域,首先根据行驶在丘陵地区的混合动力重型卡车的工况特点,建立AG‑ECMS策略;在AG‑ECMS策略基础上进行坡道预测扩展,通过前方道路坡度判断长短时间下坡工况并计算对应的放电系数,对等效燃油消耗因子进行修正,得到SP‑AG‑ECMS策略;然后利用伞蜥算法,以燃油经济性为目标,对待优化参数进行迭代优化;最后以获得的最优参数制定的SP‑AG‑ECMS策略通过多种参数对发动机和驱动电机进行在线功率分配。本发明具有最大限度发挥山区混合动力重型卡车的制动能量回收潜力,提高车辆的燃油经济性的特点。

    The invention discloses a ramp prediction adaptive ECMS hybrid electric vehicle energy management method, and relates to the technical field of hybrid electric vehicles, and the method comprises the steps: firstly building an AG-ECMS strategy according to the working condition characteristics of a hybrid electric heavy truck running in a hilly area; carrying out ramp prediction expansion on the basis of the AG-ECMS strategy, judging a long-time and short-time downhill working condition according to the gradient of a front road, calculating a corresponding discharge coefficient, and correcting an equivalent fuel consumption factor to obtain an SP-AG-ECMS strategy; then, iteratively optimizing the to-be-optimized parameters by using an umbrella-exponent algorithm and taking fuel economy as a target; finally, an SP-AG-ECMS strategy formulated according to the obtained optimal parameters is used for conducting online power distribution on an engine and a driving motor through the multiple parameters. The method has the characteristics that the braking energy recovery potential of the hybrid power heavy truck in the mountainous area is exerted to the maximum extent, and the fuel economy of the truck is improved.
