The invention discloses a hybrid electric vehicle, a control method and device thereof and a storage medium. The control method of the hybrid electric vehicle comprises the following steps that operation parameters of the hybrid electric vehicle are obtained; the corresponding motor torque limit value is obtained according to the operation parameters, and the motor torque limit value is the motor torque enabling a speed reducing mechanism connected with a motor in the hybrid electric vehicle not to be knocked under the corresponding operation parameters; determining an engine initial torque and a motor initial torque of the hybrid electric vehicle, and adjusting the engine initial torque and the motor initial torque according to the motor torque limit value to obtain an engine target torque and a motor target torque; and an engine of the hybrid electric vehicle is controlled according to the target engine torque, and a motor is controlled according to the target motor torque. According to the control method of the hybrid electric vehicle, the knocking noise of the hybrid electric vehicle can be reduced with zero cost.

    本发明公开了一种混合动力汽车及其控制方法、装置以及存储介质。其中,混合动力汽车的控制方法包括以下步骤:获取混合动力汽车的运行参数;根据运行参数得到对应的电机扭矩极限值,其中,电机扭矩极限值为对应运行参数下,使混合动力汽车中与电机连接的减速机构不发生敲击的电机扭矩;确定混合动力汽车的发动机初始扭矩和电机初始扭矩,并根据电机扭矩极限值对发动机初始扭矩和电机初始扭矩进行调整,得到发动机目标扭矩和电机目标扭矩;根据发动机目标扭矩对混合动力汽车的发动机进行控制,并根据电机目标扭矩对电机进行控制。该混合动力汽车的控制方法,可以实现零成本地降低混合动力汽车的敲击噪音。
