The invention relates toan automatic driving mode control methodfor a hybrid electric vehicle and a storage medium. The method comprises the following steps: planning a reference driving track of a vehicle by combiningworking condition historical data of a historical driving road section with working condition information collected by a vehicle-mounted GPS;when the vehicle runs on the reference driving track, carrying out calculation by taking the driving speed of the vehicle on the reference driving track and the acceleration at each moment as the input of a dynamic planning algorithm to obtain a reference torque of an engine of the vehicle, a reference torque of a driving motor and a reference working mode at each moment; after model predictioncontrol, acquiring aninput torque of the engine of the vehicle, an input torque of the driving motor and aworking mode of the whole vehicle. Through combination of the dynamic planning algorithm with model predictive control, predictive controlis carried out on the economy of the hybrid electric vehicle in the automatic driving mode of the hybrid electric vehicle, so that energy consumption of the hybrid electric vehicle in the automatic driving mode is reduced.

    本发明涉及一种混合动力汽车自动驾驶模式控制方法及存储介质,所述方法包括以下步骤:将历史行驶路段的工况历史数据及车载GPS采集的工况信息结合规划车辆的参考行驶轨迹;当车辆行驶在参考行驶轨迹上时,将该参考行驶轨迹上车辆的行驶速度及每一时刻的加速度作为动态规划算法的输入,进行计算得到车辆的发动机的参考转矩、驱动电机的参考转矩以及每一时刻的参考工作模式;进行模型预测控制后,得到车辆的发动机的输入转矩、驱动电机的输入转矩以及整车工作模式;通过动态规划算法和模型预测控制相结合,在混合动力汽车在自动驾驶模式的过程中,对混合动力汽车的经济性进行预测控制,减少混合动力汽车在自动驾驶模式时的能源消耗。
