The embodiment of the invention provides a starting control method and device of a vehicle, electronic equipment and a storage medium, and can avoid the problem of voltage fluctuation of a high-voltage system of the vehicle caused by insufficient output power of a power battery when the vehicle is started in extremely cold weather. The vehicle starting control method comprises the steps that a vehicle ignition instruction of a user is responded, a vehicle high-voltage system is powered on, and an engine is started; when it is determined that the rotating speed of the engine reaches the first set value, a rotating speed increasing instruction is sent to the engine, the rotating speed increasing instruction is used for controlling the rotating speed of the engine to be increased, and generated output power is transmitted to a vehicle high-pressure system through a crankshaft motor connected with the engine; when it is determined that the voltage of the vehicle high-voltage system reaches a second set value and the fluctuation amplitude of the voltage is smaller than a third set value, an enabling instruction is sent to a direct current-direct current converter of the vehicle, and the enabling instruction is used for controlling the direct current-direct current converter to supply power to electric appliances of the vehicle.

    本申请实施例提出了一种车辆的启动控制方法、装置、电子设备及存储介质,能够使车辆在极寒天气中启动时,避免因动力电池输出功率不足导致车辆高压系统电压波动的问题。其中,车辆的启动控制方法包括:响应用户的车辆点火指令,对车辆高压系统进行上电以及启动发动机;当确定发动机的转速达到第一设定值时,向发动机发送转速提升指令,所述转速提升指令用于控制发动机的转速增大,并通过与发动机相连的曲轴电机将产生的输出功率输送至车辆高压系统;当确定车辆高压系统的电压达到第二设定值且电压的波动幅度小于第三设定值时,向车辆的直流‑直流变换器发送使能指令,所述使能指令用于控制直流‑直流变换器向车辆的电器供电。
