The control device 110 includes a detection module 112 and a control module 114. S10 may be implemented by the detection module 112 and S20 and S30 may be implemented by the control module 114. Alternatively, the detection module 112 is used to detect the battery status of the vehicle; the control module 114 is configured to control the vehicle to perform an early warning prompt when the battery is in the thermal runaway state, and to control the door state of the vehicle to be switched to the unlock state.
Specifically, the causes of thermal runaway include mechanical and electrical causes such as battery crash squeezing, pin punching, etc., and electrochemical causes such as battery overcharge and overdischarge, low-temperature charging, etc. When thermal runaway of one battery cell occurs, adjacent battery cells are affected by the thermal runaway, and thermal runaway can occur successively, so that thermal runaway spreads. When the vehicle battery is out of control thermally, personnel in the vehicle can not correctly deal with the situation due to panic or the vehicle is trapped in the vehicle due to the fact that the vehicle self-ignites and the vehicle door cannot be unlocked, and finally a vehicle safety accident is caused. Therefore, when the thermal runaway of the vehicle battery occurs, it is important to prompt the action of the vehicle occupant and to control the vehicle.
In the running process of the vehicle, the vehicle central control large screen judges whether the Battery is in a normal state or not by monitoring a Controller Area Network (CAN) signal provided by a Battery Management System (BMS).

When the thermal runaway of the battery has spread, the vehicle should be stopped as soon as possible to avoid casualties.
Therefore, when the thermal runaway of the vehicle battery occurs, the vehicle is controlled to be switched to the automatic driving mode, and the vehicle is further controlled to stop nearby, so that the output power of the battery can be effectively reduced, and the battery is gradually restored to a normal state.
In some embodiments, under the condition that the thermal runaway is spread, the vehicle is controlled to be switched to an automatic driving mode and to be parked nearby, so that more escape time can be reserved for people in the vehicle, and the accident occurrence probability is reduced.
