The invention provides an emergency start control method and device, electronic equipment and a vehicle, which can perform self-inspection on a motor controller after entering an emergency start mode to ensure that the motor controller can smoothly execute emergency start. After the self-inspection is passed, sufficient power supply is ensured by forbidding the engine to stop; when the starting rotating speed reaches a rotating speed threshold value, voltage output of a motor controller is controlled, and it is guaranteed that the motor controller can output stable high voltage to supply power to a high-voltage accessory; when the direct-current side voltage is larger than or equal to a preset voltage threshold value, after high voltage is converted into low voltage through a direct-current converter, power is supplied to a low-voltage accessory, and power-on of the whole vehicle is completed; after the low-voltage accessory is powered on, vehicle speed limitation is started until the quit condition is met, the emergency starting mode is quitted, and it can be guaranteed that enough power is provided for maintaining operation of the high-voltage accessory and the low-voltage accessory when the engine is independently driven through vehicle speed limitation.
本申请提供一种应急启动的控制方法、装置、电子设备及车辆,能够在进入应急启动模式后,对电机控制器进行自检,保证电机控制器可以顺利的执行的应急启动;在自检通过后,通过禁止发动机停机保证充足的动力供应;在发动转速达到转速阈值时,控制电机控制器的电压输出,保证电机控制器可以输出稳定的高电压,给高压附件供电;当直流侧电压大于等于预设的电压阈值时,通过直流转换器将高压转化为低压后,向低压附件供电,完成整车上电;在低压附件上电完成,开启车速限制,直至满足退出条件,退出应急启动模式,进行车速限制可以保证发动机单独驱动时有足够的功率维持高低压附件的运行。
