Problems solved by technology
However, the hydrogen concentration sensor is arranged in a semi-enclosed or open space, and the alarm can only be triggered when the hydrogen leakage concentration reaches a certain set threshold, and the hydrogen gas is easy to diffuse, and it is impossible to detect minor leakage, which poses a safety hazard; moreover, when the vehicle After parking and power failure, it is impossible to detect hydrogen leakage in the pipeline, resulting in the hydrogen leakage detection result being obtained after the vehicle is started, which is not conducive to driving safety

The invention discloses a hydrogen leakage detection system for an automobile. The hydrogen leakage detection system is applied to a hydrogen fuel automobile. The hydrogen leakage detection system forthe automobile comprises a control module and a pressure sensor; the pressure sensor is arranged in a hydrogen pipeline; a computer program is stored in the control module, and when the control module executes the computer program, the following steps are carried out, after a detection instruction is received, a first pressure value collected by the pressure sensor in the hydrogen pipeline is obtained; after the first pressure value is collected, a first electromagnetic valve is controlled to be opened, and a second pressure value collected by the pressure sensor in the hydrogen pipeline is obtained; and the hydrogen leakage state is determined according to the first pressure value and the second pressure value. According to the technical scheme, the mode that the hydrogen leakage is determined by detecting the hydrogen concentration in a traditional scheme is replaced, the hydrogen leakage in the hydrogen fuel cell electric automobile can be accurately detected, the hydrogen fuel cell is started only after detection is safe, and the driving safety of the hydrogen fuel cell electric automobile is improved.
Description
technical field [0001] The invention relates to the technical field of gas detection, in particular to a vehicle hydrogen leakage detection system. Background technique [0002] At present, my country is vigorously promoting hydrogen fuel cell electric vehicles, which have the characteristics of zero emission, high efficiency, low noise, and fast energy replenishment, and are recognized as the most ideal vehicle power plant to replace traditional internal combustion engines in the future. Hydrogen is a colorless, odorless and non-toxic gas at normal temperature and pressure. It has the characteristics of flammability, explosion, leakage, and diffusion. The safe use of hydrogen energy is one of the important issues in the development of hydrogen fuel cell vehicles. It is especially worth mentioning that hydrogen ranks first in the periodic table of elements. Hydrogen molecules have a small diameter and light weight. Compared with other gas or liquid fuels, they are easier to ...
