The existing car body pressure release valve is a simple paster mechanism, when a car is closed, a car door pushes gas outside the car to be pressed into the car, so that the instantaneous air pressure in the car is increased, at the moment, the air pressure difference is formed between the inside and the outside of the car, the cover paster on the pressure release valve is pushed to lift a certain angle under the action of the air pressure difference, and the air pressure in the car is discharged until the air pressure is balanced with the air pressure outside the car. After closing the door, the cover patch on the pressure release valve returns to the original cover position under the action of gravity so as to keep air tightness. However, after the door is closed, the simple paster mechanism returns to the initial sealing cover position under the action of gravity, so that the air tightness cannot be guaranteed to be good after the door is closed, if the pressure release size of the vehicle body pressure release valve is reduced, the pressure difference between the inside and the outside of the vehicle cannot be balanced rapidly in the process of closing the vehicle door, and the difficulty in closing the door can be improved.

when the pressure release valve is an electromagnetic-absorption electric pressure release valve, if the pressure release valve is in an open state, a power supply leading to the pressure release valve is opened until a metal patch on a pressure release valve blade is absorbed by an electromagnetic structure on the pressure release valve body so as to enable the pressure release valve to be in a closed state.
4. The control method of a pressure relief valve according to claim 1, wherein said step of controlling the pressure relief valve to be in an open state comprises:
when the pressure relief valve is an electric pressure relief valve which is pressed by overturning, if the pressure relief valve is in a closed state, the control motor drives the blade rotating shaft to rotate, so that the pressure relief valve blade is separated from the exhaust pressure relief channel, and the pressure relief valve is in an open state.
5. The control method of a pressure relief valve according to claim 1, wherein said step of controlling the pressure relief valve to be in an open state comprises:
when the pressure release valve is an electromagnetic-attraction electric pressure release valve, if the pressure release valve is in a closed state, a power supply leading to the pressure release valve is closed, and magnetic force between a metal patch on a pressure release valve sheet and an electromagnetic structure on the pressure release valve body is canceled so that the pressure release valve is in an open state.
6. A control device of a pressure release valve, characterized in that the control device of the pressure release valve comprises:
the detection module is used for detecting whether the vehicle is in a closed state or not;
the first control module is used for controlling the pressure release valve to be in a closed state if the detection result shows that the vehicle is in a closed state;
the second control module is used for controlling the pressure release valve to be in an open state if the detection result indicates that the vehicle is not in a closed state;
the detection module is used for:
when detecting that the structural devices which can enable the vehicle not to be in the closed state are closed and the duration exceeds the preset duration, the detection result is that the vehicle is in the closed state, wherein the structural devices which enable the vehicle not to be in the closed state comprise: vehicle doors, windows, skylights and back doors;
when detecting that the structural devices which can enable the vehicle not to be in the closed state are not closed or the structural devices which can enable the vehicle not to be in the closed state are closed and the duration time is not longer than the preset time, the detection result is that the vehicle is not in the closed state.
7. A control device for a pressure relief valve, characterized in that the control device for a pressure relief valve comprises a processor, a memory, and a control program for a pressure relief valve stored on the memory and executable by the processor, wherein the control program for a pressure relief valve, when executed by the processor, carries out the steps of the control method for a pressure relief valve according to any one of claims 1 to 5.
8. A readable storage medium, characterized in that a control program of a pressure relief valve is stored on the readable storage medium, wherein the control program of the pressure relief valve, when executed by a processor, carries out the steps of the control method of the pressure relief valve according to any one of claims 1 to 5.
