Vehicle control method and device, electronic equipment and vehicle Technical Field The application relates to the technical field of vehicle control, in particular to a vehicle control method and device, electronic equipment and a vehicle. Background Currently, when a vehicle is under a low-power condition (for example, after long-distance running, the power consumption is exhausted) and the vehicle is under high voltage due to misoperation or protection of a control system of the vehicle, the control system can still execute the full power-off operation indiscriminately even if the vehicle is still in a static state and has no emergency requirement. However, in the low-temperature environment, the low-temperature environment further inhibits the discharge capacity of the battery, so that even if the State of Charge (SOC) value of the vehicle is slightly higher than the theoretical lower limit, the battery cannot output enough current to complete re-power-up. Therefore, there is still a problem that the vehicle loses the self-recovery capability due to neglecting the power characteristics at the low SOC of the battery, resulting in a problem that the vehicle cannot be controlled effectively.
