The invention discloses an engine starting control method and device, a storage medium and a hybrid vehicle, and relates to the technical field of vehicle control. The method comprises the steps that when an operation mode of the vehicle is switched to a power dividing mode, the starting demand power of a P1 motor is determined according to the current vehicle speed of the vehicle, the total permissible charging power is increased according to the starting demand power; and determining the distributed charging power of the P1 motor according to the improved total allowable charging power, and controlling the P1 motor to drag an engine of the vehicle to start based on the distributed charging power. The starting demand power of the P1 motor can be determined according to the current vehicle speed of the vehicle, then the total permissible charging power is improved, the distributed charging power of the P1 motor is improved, compared with an existing mode, engine starting can be completed without extracting the charging power used by the P3 motor in the recovery process, the energy recovery capacity of the vehicle is guaranteed, and the energy recovery efficiency of the vehicle is improved. And the problem that the vehicle moves forwards or the braking force is weak due to starting of the engine in the sliding process is solved.
本申请公开一种发动机启动控制方法、装置、存储介质及混动车辆,涉及车辆控制技术领域,该方法包括:在车辆的运行模式切换至功率分流模式时,根据车辆的当前车速确定P1电机的启动需求功率,并根据启动需求功率对总许可充电功率进行提升;根据提升后的总许可充电功率确定P1电机的分配充电功率,并控制P1电机基于分配充电功率拖动车辆的发动机启动。由于本申请可根据车辆的当前车速确定P1电机的启动需求功率,进而提升总许可充电功率,使P1电机的分配充电功率得到提升,相较现有方式,无需抽取回收过程P3电机使用的充电功率即可完成发动机启动,保证了车辆的能量回收能力,避免滑行过程中启动发动机造成的车辆前窜或制动力弱的问题。
