Vehicle collision protection method and device and computer storage medium

The invention discloses a vehicle collision protection method and device and a computer storage medium, and the method comprises the steps that a vehicle control unit receives a collision signal sent by a collision sensor of a target vehicle, and the collision sensor is assembled at the position corresponding to a collision protection part of the target vehicle and comprises a power battery bin and/or a high-voltage bin of the target vehicle; the vehicle control unit judges whether the collision effect meets a preset loop protection condition or not according to the collision signal; if yes, the vehicle control unit cuts off a high-voltage loop of the target vehicle. Therefore, when the collision signals of the power battery bin and the high-voltage bin of the vehicle are detected to meet the preset loop protection condition, the high-voltage loop of the vehicle can be automatically cut off, the situation that a driver cannot respond to early warning in time after an emergency collision accident occurs is red
