Abstract

The invention relates to the technical field of hydrogen energy automobiles, in particular to a hydrogen safety system of a fuel cell hydrogen energy automobile. The system comprises a hydrogen management system, a first hydrogen concentration sensor, a second hydrogen concentration sensor, a third hydrogen concentration sensor, a fourth hydrogen concentration sensor, a vehicle control unit, an automobile instrument, a hydrogen fuel cell system, a high-voltage distribution box, a power battery system, a driving motor system, a driving motor and an air conditioner compressor. Therefore, the hydrogen safety system of the hydrogen fuel cell automobile can accurately, quickly and sensitively send alarm information according to the hydrogen leakage level and control the whole automobile to takecorresponding protective measures, the safety of a driver and passengers is guaranteed, and the running safety performance of the automobile is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of hydrogen energy vehicles, in particular to a hydrogen safety system and a control method for a fuel cell hydrogen energy vehicle. Background technique [0002] With the rapid development of hydrogen energy vehicles, its use is becoming more and more popular. However, during the operation of hydrogen energy vehicles, there will be problems of hydrogen leakage. If the hydrogen energy vehicle is not detected when the hydrogen leaks, and the driver fails to deal with it in time, it will bring great safety hazards and property losses to the driver and passengers. Contents of the invention [0003] In view of this, the present invention provides a hydrogen safety system and control method for a fuel cell hydrogen energy vehicle. [0004] The invention provides a hydrogen safety system for a fuel cell hydrogen energy vehicle, which includes a vehicle controller, an automobile instrument, a hydrogen fuel cell...
