Abstract

The invention discloses a hydrogen safety control system and method for a hydrogen fuel cell vehicle. The hydrogen safety control system of the hydrogen fuel cell automobile comprises a hydrogen supply system controller, and a hydrogen bottle opening electromagnetic valve, an infrared module, a safety air bag controller, a whole automobile controller, a fuel cell controller, an automobile body controller and a combination instrument which are electrically connected with the hydrogen supply system controller. The hydrogen safety control method of the hydrogen fuel cell vehicle uses the hydrogensafety control system. The invention has the beneficial effects that when the hydrogen supply system controller detects that the hydrogen concentration inside or outside the vehicle is too high, theair bag controller detects collision, the fuel cell controller detects that a fuel cell system has serious faults, or the whole vehicle controller detects that a whole vehicle has electric leakage orhigh-voltage interlocking circuit faults, the hydrogen bottle opening electromagnetic valve can be immediately closed to ensure the safety of vehicles and users.

Description

technical field [0001] The invention relates to the technical field of hydrogen fuel cell vehicles, in particular to a hydrogen safety control system and method for hydrogen fuel cell vehicles. Background technique [0002] The characteristics of hydrogen such as volatile, flammable, explosive and hydrogen embrittlement make hydrogen have certain safety hazards in the process of use. Due to the lack of experience in the use of hydrogen, the safe use of gas in automobiles is very important. Contents of the invention [0003] The object of the present invention is to propose an intelligent hydrogen safety control system for a hydrogen fuel cell vehicle with a high safety factor in view of the above-mentioned deficiencies in the prior art. [0004] A hydrogen safety control system for a hydrogen fuel cell vehicle of the present invention includes a hydrogen supply system controller, a hydrogen bottle mouth solenoid valve electrically connected to the hydrogen supply system co...
