Specifically, a vehicle high-voltage safety control method according to a specific embodiment of the present disclosure includes the following steps:
step S110, acquiring first information representing the opening and closing state of the charging opening cover;
step S111, determining the opening and closing state of the charging opening cover according to the first information; if the charging port cover is in the open state, jumping to step S113; if the charging port cover is in the closed state, the process goes to step S112.

And step S115, controlling the vehicle to be in a non-high-pressure state.
Of course, it can be understood that when the charging port cover is opened, the charging port is not connected with the charging gun, but the vehicle speed is greater than the threshold value, the vehicle can be controlled to display the reminding information to remind people, because although the charging port cover is opened and the charging gun is not connected, the safety risk of people may exist, at the moment, the vehicle speed is higher than a certain threshold value, people are not easy to touch the high-voltage charged part of the charging port, and at the moment, if the vehicle is controlled to be in a non-high-voltage state, other safety accidents of the vehicle may occur, so that at the moment, the vehicle is not controlled to be in the non-high-voltage state, but the vehicle.
Firstly, whether the charging opening cover is opened or not is judged, no risk exists when the charging opening cover is not opened, if the charging opening cover is opened, whether the charging opening is connected with a charging gun or not and the speed of the vehicle are judged, the vehicle is controlled to be in a non-high-voltage state when conditions are met, the subsequent process is not needed when the charging opening cover is only detected to be closed, the calculation amount can be reduced, and the reaction speed is improved.
