The invention is suitable for the technical field of vehicles, and provides a vehicle starting control method and device, a vehicle and a storage medium. The method comprises the following steps: acquiring gear change information of a vehicle; if the gear change information is that the parking gear is switched into the driving gear, an idle speed control instruction is sent to the engine, and the engine is controlled to operate at the idle speed at the preset target rotating speed; sending a rotating speed control instruction to the motor according to the target rotating speed, and adjusting the rotating speed of the motor; whether the rotating speed difference between the motor and the engine is smaller than a preset difference threshold value or not is judged; and if the rotating speed difference is smaller than the difference threshold value, the gearbox is controlled to shift. The engine is controlled to have a stable idle speed, the speed regulation of the motor is further influenced by utilizing the stability of the idle speed control of the engine, the rotating speed of the motor is regulated to be the same as or similar to the rotating speed of the engine, the gear shifting of the gearbox is controlled, the abnormal sound phenomenon of the gear shifting can be reduced, and the smoothness during the gear shifting starting of the vehicle can be ensured.

    本发明适用于车辆技术领域,提供了一种车辆的起步控制方法、装置、车辆及存储介质。本方法包括:获取车辆的档位变化信息;若档位变化信息为由驻车档切换为行车档,则向发动机发送怠速控制指令,控制发动机在预设的目标转速下怠速运转;以及根据目标转速,向电机发送转速控制指令,调节电机的转速;判断电机与发动机的转速差是否小于预设的差值阈值;若转速差小于差值阈值,则控制变速箱进档。本发明控制发动机有一个稳定怠速转速,利用发动机怠速控制的稳定性,进一步影响电机的调速,将电机的转速调节至与发动机转速相同或相近,控制变速箱进档,能够降低进档异响现象的发生,可以保证车辆换挡起步时的平顺性。
