The invention discloses a hybrid power vehicle control method and device and a readable storage medium. After a hybrid power mode is started, the current engine rotating speed is determined according to the vehicle speed by obtaining the vehicle speed and the whole vehicle required power, and the engine required torque T is determined according to the current engine rotating speed and the whole vehicle required power; and a first preset value T1 and a second preset value T2 corresponding to the current rotating speed of the engine are determined, and the output torque of the engine is determined according to the current rotating speed of the engine, the required torque T of the engine, T1 and T2. Different engine output torques are determined according to the current required torques T, T1 and T2, so that the working efficiency of the vehicle engine is improved by controlling the output of the engine torques, the purpose of reducing the overall fuel consumption of the vehicle is achieved, the fuel economy of the vehicle is improved, and the problem that the fuel economy of the vehicle is not good when the vehicle has a high-power demand or a low-power demand in the hybrid power mode is solved.
本发明公开了一种混合动力车辆控制方法、装置和可读存储介质,在启动混合动力模式之后,通过获取车速和整车需求功率,根据车速确定当前发动机转速,根据当前发动机转速和整车需求功率确定发动机需求扭矩T,并确定当前发动机转速下对应的第一预设值T1值和第二预设值T2值,根据当前发动机转速、发动机需求扭矩T、T1和T2确定发动机输出扭矩。本发明根据当前需求扭矩T、T1和T2的大小确定不同的发动机输出扭矩,从而通过控制发动机扭矩的输出以使车辆发动机工作效率提高,达到减少车辆整体燃油消耗的目的,提高车辆燃油经济性,解决了在混合动力模式下,车辆有大功率需求或小功率需求时出现的车辆燃油经济性不好的问题。
