The invention discloses an engine starting control method of a hybrid electric vehicle, a vehicle and a storage medium. The engine starting control method comprises the steps: S100, judging a starting mode of an engine; if the engine is started by a generator, entering the step S200; and if the engine is started by adopting a starter, entering the step S700; S200, calculating a starting torque T1 of the generator; S300, calculating a balance torque Tb of the driving motor; S400, calculating an adjusting torque Tpi of the driving motor; S500, calculating an output torque T2 of the driving motor; S600, controlling the driving motor to output torque according to the T2 so as to maintain the balance of the vehicle; and S700, maintaining balance of the vehicle in a braking mode. According to the engine starting control method of the hybrid electric vehicle, a phenomenon that the vehicle moves forwards or backwards during starting can be effectively avoided, the stability of the engine during starting is improved, and furthermore, the driving experience is improved.

    本发明公开了一种混合动力汽车的发动机启动控制方法、车辆及存储介质。发动机启动控制方法包括步骤:S100:判断发动机的启动方式;若发动机采用发电机启动,则进入步骤S200;若发动机采用起动机启动,则进入步骤S700;S200:计算发电机的启动扭矩T1;S300:计算驱动电机的平衡扭矩Tb;S400:计算驱动电机的调节扭矩Tpi;S500:计算驱动电机的输出扭矩T2;S600:控制驱动电机按照T2进行扭矩输出,以维持车辆平衡;S700:车辆利用制动方式维持平衡。本发明的混合动力汽车的发动机启动控制方法能够有效避免车辆启动时发生前移或者后移现象,提高发动机启动时的稳定性,进而提升驾乘体验。
