The invention discloses a control method of a hybrid power vehicle, a storage medium, a controller and a vehicle, the hybrid power vehicle comprises an engine and a power generation and starting integrated motor, and the method comprises the steps that in response to an engine stop command, the rotating speed of the power generation and starting integrated motor is obtained in real time; determining a target shutdown torque according to the rotating speed; and the power generation and starting integrated motor is controlled through the target shutdown torque so as to pull and stop the engine, and in the engine pulling and stopping process, the target shutdown torque is updated according to the rotating speed in the engine pulling and stopping process. According to the method, in the process of controlling the power generation and starting integrated motor to pull and stop the engine according to the target shutdown torque determined by the rotating speed of the power generation and starting integrated motor, self-learning is carried out on the target shutdown torque of the power generation and starting integrated motor to pull and stop the engine based on the rotating speed, obtained in real time, of the power generation and starting integrated motor; and the target shutdown torque is updated, and the problems of rotating speed reversal, falling and abnormal sound in the engine shutdown process under the actual use working condition of the whole vehicle are solved.

    本发明公开了一种混合动力车辆的控制方法及存储介质、控制器、车辆,混合动力车辆包括发动机和发电启动一体电机,方法包括:响应于发动机停机命令,实时获取发电启动一体电机的转速;根据转速,确定目标停机扭矩;利用目标停机扭矩对发电启动一体电机进行控制,以拉停发动机,并在拉停发动机的过程中,根据拉停发动机过程中的转速更新目标停机扭矩。该方法在根据由发电启动一体电机的转速确定的目标停机扭矩对发电启动一体电机进行控制拉停发动机的过程中,还基于实时获取的发电启动一体电机的转速对发电启动一体电机拉停发动机的目标停机扭矩进行自学习,更新目标停机扭矩,解决整车实际使用工况下发动机停机过程转速反转、跌坑和异响问题。
